When a plumbing system is set lower than a municipal sewer line, sewage pumps are used to pump wastewater from a collection basin up to the main sewer. In septic tank systems sewage pumps often move fluid waste to a leach field. Sewage pumps are designed to pump fluids containing soft solids of up to 2” in diameter. They are submersible and often controlled by float switches that activate the pump when the liquid level in the basin rises. Sewage pumps are rated in horsepower and most models are capable of moving several thousand gallons of fluid per hour.

Zoeller Sewage Pumps Review:
Zoeller Ejector Pumps are often referred to as a sewage pump or sewage grinder pump. These types of pumps replace gravity during the transportation of waste from a plumbing space that is situated underneath the remainder of the system. These pumps are often found in a bathroom, laundry room or other plumbing fixture that is installed below the level of the main sewer. Ejector Pumps are considered high volume/low pressure solids handling pump. Ejector pumps do not have grinding blades. They use an intake that spins the gray water or sewage through the bottom of the pump and forces it under pressure out of the outlet and into the discharge pipe. These pumps are generally designed to handle up between 0-2” diameter solids. The most common application for the Zoeller Sewage Pump is to move gray water or raw sewage from the residence to a septic tank or sewer main. These pumps are made for the tough and demanding task of transferring effluent and wastewater.
Zoeller has many popular Series under this category, for example the “Builder Series”, “Aqua-Mate” and “Waste-Mate” all fall under the Zoeller Sewage Ejector Pump category. These submersible pumps are designed for use in residential or light commercial dewatering and wastewater applications and can be used to transfer effluent or raw sewage. The innovative vortex impeller design reduces the risk of clogging and allows each pump to pass 2” spherical solids. These pumps are constructed of a non-corrodible engineered plastic motor housing, pump housing, base and impeller.
Another popular model is the Sewage Waste 600, which is part of Zoeller’s Sewage Pump collection.

How To Size A Sewage Pump System
Sewage stinks. It’s not a very pleasant thing to think about and most people probably would prefer their sewage to be out of sight and out of mind. Few things are as big a headache for a property owner or municipality manager as backed up sewage water. Whether the building in question is a home or business, the smell of sewage can produce a dreadful environment. Removing wastewater and sizing a new pump for your sewage pump system is an involved process.
If you are experiencing a problem such as the sewage water backing up or simply not draining quickly enough, it is important to determine the origin of the problem and think about possible solutions. If a pump stopped working because of age or natural wear, it is easy enough to replace the old model with a new one. But you should take the opportunity to examine the holistic health of your sewage system.
PumpProducts.com technicians installing a sewage pump system.
Similarly, if you are building a new house or you just refurbished your basement and want to add a bathroom, it is imperative to consider all the aspects of wastewater removal in your system. If the system is a new project, you may need to dig a new sewage pit to have a basin installed.
Examining the whole of a system can help you update your infrastructure to comply with new codes, identify potential problem points before they occur or simply make your fluid transportation more efficient, saving time and money in the long run.
PumpProducts.com will walk you through the process of sizing a sewage pump for a system. First, it is essential to understand the basics of municipal sewage systems and whether or not you actually need a sewage pump.
UNDERSTANDING HOW SEWAGE SYSTEMS WORK
Most American municipal systems have two types of underground sewer lines dedicated to water collection and disposal: the storm sewer and the sanitary sewer.
The storm sewer collects rainwater surface runoff from catch basins and transports the water to the nearest natural reservoir, such as a river or stream. The sanitary sewer transports wastewater directly from building sewage systems to a water treatment plant where contaminants are removed (Some older cities have combined sewer systems).
For buildings at grade (ground level), gravity takes care of transporting the wastewater to the sanitary sewer. Sewage pumps are necessary if the sanitary sewer line is located at a level above your home wastewater line or if you have a toilet below the sanitary sewer line, as is often the case for basement bathrooms.
As the name suggests, sewage lifting stations also rely on sewage pumps. Lifting stations are integral links in the chain connecting neighborhoods to water treatment facilities.
Check the codes for your area to see what aspects you are responsible for within the system. Your municipality should also have exact records of where your property line ends and public property begins. To determine if a problem is with the property sewer line or the public line, try contacting the town or utility company. A plumbing professional can also assist with diagnosis.
The sewage system can be configured in various ways. Automatic systems will require float switches and a control panel to turn the pump on or off.
A simplex system is a one pump system while a duplex system is a two pump system in which each pump serves as a redundancy to share the workload, resulting in less wear on the pumps. Simplex systems are mostly used in domestic settings. Duplex systems are recommended for municipal, commercial and industrial applications.
Selecting a Model
When selecting a pump model you should know the voltage, phase of power, amperage and horsepower of your previous pump. This information should be listed on a pump tag. The video below provides a guide to using the tag to identify your pump. If you cannot locate the tag or if the label is degraded, you can try taking a picture of the pump and sending it to the experts here at PumpProducts.com.
The pump’s discharge size is important for configuring the pump with the existing pipe system; the discharge pipe size should never be a smaller diameter than the pump’s discharge outlet. Suction/discharge sizes will sometimes be listed on the casing.
The average size for waste solids in residential systems is 1 ½” or larger. For commercial or industrial systems, the average solids size is 2 ½” or larger.
Flow and total dynamic head (TDH) are integral in selecting a pump. Your water flow requirements, measured in GPM, are based on the number of people using the system, peak usage times and the number of water fixtures (e.g. toilet, sink). The charts for discerning water supply fixture units for both individual and group fixtures, as well as a chart for converting the WSFU demand to GPM can be found here.
The GPM is also critical information that you need to calculate your TDH. Scouring the pipes is important to prevent clogs, water hammer and backflow. Once you have the flow and head you can select a pump using a manufacturer’s pump performance curve charts.
Selecting a Basin
The sewage basin or holding tank serves as a temporary receptacle for the wastewater while also housing the submersible sewage pump that ejects the wastewater to the main sewer line. Correct sizing of the basin is critical for smooth discharge, preventing overflow and ensuring safe pump cycling.
To size your basin, here’s what you should keep in mind:
–Whether you are using a simplex or duplex system. –Required construction material of the basin body and of the lid (poly, fiberglass, steel). –Pipe fits: The basin has a discharge and suction pipe that should size match with both the sewer line pipe and the pump’s discharge pipe. –The basin lid should have a vent to prevent air locking and aid in the management of gases. –Required size for the basin inlet. –Guide Rails: It is strongly recommended to install a basin on a guide rail system. The guide rail makes removing the pump easy, reducing maintenance time and cost while keeping personnel safe.
The actual basin capacity is important to make sure the pump cycles properly. For instance, if the basin is too small for your flow requirements, the pump will keep running to evacuate the water and prevent overflow.
A minimum diameter of 24” is required for simplex systems while duplex systems require at least 36”. Here’s a handy chart from Goulds that explains how to use your GPM and gallons per inch to size your basin.
Other Accessories and System Components
If you are installing a new control panel, make sure you know the proper electrical supply requirements for the pump and building in question. Most homes and standard commercial buildings in the United States typically operate at a single phase power and 115/230 V. In the U.S., electrical grids operate with a frequency of 60 Hz. Amp range is also an important factor.
PumpProducts.com experts recommend using a wide angle tethered style float switch as other switches might be more susceptible to clogging from waste solids. If you have correctly sized your basin, make sure the float switch cord is the proper length to operate within that basin. The amperage range of the float should be compatible with the pump.
A check valve is required to prevent backflow and for code compliance.
Sewage or Grinder (or Shredder?) What’s the Difference?
When considering terminology, remember that all grinder pumps are sewage pumps but not all sewage pumps are grinder pumps. Sewage pumps are designed to pass waste solids up to 2” in diameter. Grinder pumps can turn waste solids into a slurry that can be more easily transported through the piping. In this case, “waste solids” refers to organic waste and standard issue toilet paper that can be easily broken down.
A common misconception is that grinder pumps can macerate heavy objects such as feminine products, plastics and loose items of clothing. If clogging is a consistent problem – say you own a motel and guests are inconsiderate about what they flush down the toilet – it may behoove you to select a dedicated nonclog shredder or cutter pump. As seen in this video, shredders are expressly designed to destroy synthetic solids, such as diapers or plastic bottles.
Sizing and configuring a sewage system is a delicate, comprehensive process. Other important factors to keep in mind are the temperature of the liquid that will be pumped, as well as the construction materials of the pump itself. Durable materials and a strong warranty are recommended. Know if the materials are rated for indoor or outdoor applications. Outdoor components require weatherproofing.
If you do not want to deal with the inconvenience and expense of buying separate components consider buying a sewage system package. Packages can include all the pre-assembled components, streamlining the process considerably.
How To Identify The Parts Of A Sewage Pump
Most people never consider the components of a pump until one breaks. If you are not getting water or your basement is flooded, you might know that something is wrong with the pump – but you have no idea what you’re looking at. PumpProducts.com will break down the parts of a submersible sewage pump to give you a better understanding of how a pump is constructed how the parts fit together to move fluid.
Why should you be able to identify pump repair parts? As with any other piece of mechanical equipment, familiarity with the components can help you understand proper functioning, assist you in diagnosing potential problems and enable you to repair the pump yourself, should you be so inclined.
Plus, a little extra knowledge never hurt anybody.
PUMP COMPONENTS
A pump is composed of two main parts: the volute and the motor. A volute is the curved casing that receives the fluid. The fluid’s rate of flow decreases while the flow pressure increases.
Volute
Inside the volute and connected to the motor shaft is the impeller. An impeller is a rotor used to increase both the pressure and flow of a fluid. There are four components to an impeller:
–The eye, where the fluid enters. –The veins, which push the fluid. –The channels, which are the spaces in between the veins where the fluid flows. –The bore, in which the motor shaft attaches.
Impellers exist in a wide variety of types. All impellers are either single or double suction; single suction impellers allow the fluid to enter through one direction, while double suction types allow fluid to enter on either side of the impeller simultaneously.
Impellers have three main configurations: open, semi-open or closed. Open impellers have a series of vanes attached to the central unit. Semi-open impellers contain the vanes in a wear ring design to allow solids to pass through. Closed impellers have a wear ring completely surrounding the vanes. The wear ring is designed to protect the impeller from degradation over time.
It is important to keep in mind that changing the impeller type and dimensions will change the application, flow and differential head.

The next component is the diffuser. The diffuser increases the flow rate while decreasing flow velocity, which in turn increases flow pressure. Diffusers can come in a ring form separate from the impeller or as vanes on the impeller itself.
Some pumps, like submersible well pumps for instance, will be multi-stage, in which there are multiple levels of the pump, each housing its own impeller and diffuser.
The volute will also feature a suction inlet where the water enters and a discharge outlet from which the water exits.
It is important to understand how the components work together to move fluid. The shaft, powered by the motor, connects to and spins the impeller, creating suction. The suction power brings water into the volute through the inlet and ejects water out through the discharge outlet.
Motor
The next main pump component is the motor or the drive that converts electrical energy into mechanical energy. The motor is the workhorse of the pump, the thing that drives the fluid and allows it to work. The motor can either be fan cooled (TEFC) or oil cooled (ODP).
The motor consists of several parts:
–A rotor: The moving part that turns the shaft. –A stator: The stationary part of the motor’s electromagnetic circuit. –The windings, which are wires that are laid in coils, usually wrapped around a laminated soft iron magnetic core so as to form magnetic poles when energized with current. –The commutator, which consists of slip ring segments used to switch the input of most DC machines and certain AC machines. –Attached to the rotor is the spline shaft, which attaches at the other end to the impeller. This shaft delivers the mechanical power, transferred from the motor to the volute. –Covering the motor shaft is the shaft sleeve or bearing. The shaft sleeve supports the applied load while allowing the motion of the shaft and reducing friction.
The power source supplies the electricity which is transferred to the motor by the power cable. The stator consists of the windings and laminations (or thin metal sheets) and form the electromagnetic poles. The commutator alternates these poles which interacts with the rotor, making it turn. The shaft connects to the rotor on one end turning the impeller attached to the other end.
Mechanical Seal
One of the most important components is the mechanical seal, which reduces leakage between the rotating shaft and the stationary pump casing. Two seal faces or surfaces maintain contact at a sealing interface. One seal face rotates with the shaft and one is stationary.
A mechanical seal: includes a spring actuator, a primary seal face and a secondary seal face.
The seal must contain four functional components:
–First, the primary seal face, often constructed with silicon carbide, ceramic or tungsten carbide, is embedded in the pump casing and in the rotating assembly. The seal face rotates with the shaft. –The secondary seal face is stationary. –You also need a means of actuation such as a spring, in conjunction with the water pressure itself. –Finally, a means of drive. In this case, the motor.
The seal sits inside of the seal cover plate. The stationary surface presses against the cover plate and has the other surface rotating with the shaft seal, which slides inside of the entire seal. The configuration creates a watertight barrier that prevents water from leaking through to the motor.
