Grinder Pumps Buyers Guide & Reviews By

 Sewage Grinder pumps have cutting blades that grind the raw sewage into a slurry before passing it through the discharge line. Grinding the sewage into a slurry also allows the pump to reach higher heads. Sewage Grinder Pumps are designed to handle the same type of materials as a Sewage Ejector Pump, but have the ability to pass tougher solids.

Grinder Pumps are often installed in a pressure sewer system using small-diameter pipes, typically 1-1/4 inch to 2 inch along with a sewage basin to collect the sewage from wastewater discharged from the bathrooms. The grinder pump station collects all of the wastewater from the home or business and grinds it into slurry. The wastewater is then pumped to a city sewer main or directly to a septic pump system on the property.


What Is The Difference Between A Sewage Pump & A Grinder Pump?

Welcome to Inspector Pumphead’s Frequently Asked Questions! I will be answering some of the most common questions we get on a specific topic. Some of this information may also be available elsewhere, but this feature will serve as a convenient one-stop source. In this edition, I’ll talk about sewage pumps and grinder pumps.

Are sewage pumps and grinder pumps the same thing?
Sewage and grinder pumps are indeed related but are different in its construction and use. The idea that they are the same is a common misconception because many people will often use both terms interchangeably to refer to a basement pump that moves sewage water out of a building.


This is where taxonomy becomes important: all grinder pumps are sewage pumps, but not all sewage pumps are grinder pumps. Much like the old quadrilateral adage (“all squares are rectangles, but not all rectangles are squares”), this aptly describes a relationship where one (sewage) is general and the other (grinder) is specialized. The key fact is that both pumps are built to move sewage when the sewage line is above the point of collection (such as with a basement toilet).

So what’s the difference between these two kinds of pumps?

Inspector Pumphead is here to answer your questions!

The difference between the two is the type and size of the solids that can pass through the pump. Sewage pumps can pass up to 2” waste solids. “Waste solids” in this instance generally refers to human waste (gross) or other ‘soft’ solids that can easily be broken down or dissolved. Harder and thicker solids will clog and eventually damage the pump.

Grinder pumps incorporate a cutter or cutting mechanism that macerates (grinds/chops) the solids into a fine slurry to be exported. The fine slurry can be pumped higher than the solids from the sewage ejector pumps.

So should I just get a grinder pump for my house if I’m worried about clogging and waste solids?

Grinders are more costly than standard sewage pumps, require more power and are typically built for residential, commercial and/or light industrial applications where a sanitary sewer system might be strained by trying to process larger solids. Think motels or any place where a lot of people will use the system everyday without caring about what they flush. I’m talking about diapers, plastic, wipes, gloves, etc. So unless something very strange is going on at your house, you probably won’t need a grinder.

Sewage pumps are less expensive and more suitable for domestic and/or light commercial applications. Still, if you really want a grinder for more domestic applications, Liberty makes the PRG ProVore/Omnivore grinder pump series for just such a purpose.

So if I do have a grinder, can I just throw any old thing down there without worry?

Not exactly. While grinders are well equipped to macerate solids, they are not impervious to wear and tear over time. If things that should not be flushed down the toilet keep getting flushed down there, eventually, yes, even a grinder pump will suffer damage and have to be replaced. That is why you should do everything possible to make sure that people – whether they be employees, guests, tenants – do not abuse your system. As I always say, preventative care is the best way to ensure that your equipment keeps operating in good health for a long time.


The Difference Between Manual Vs. Automatic Sewage Pumps

Q: What does it mean when you say a pump is ‘manual?’ Does that mean I have to work the pump by hand?

A: Nope! It simply means that the pump has to be manually plugged in every time you want the pump to run. There is no mechanism to start the pump automatically.

Conversely, automatic pumps feature a mechanism that will start the pump in certain conditions, typically a float switch. There are a variety of different types of switches, but probably the easiest way to help you visualize it is with a tethered switch. When the water level in a pit or basin rises, the tethered float will “swing” upward and activate the switch, which in turn activates the pump.

Float switches can be purchased separately and attached to manual pumps.

Q: Okay, quick followup: when is it better to have a manual pump or vice versa?

A: It’s really just a matter of control: if you want to know exactly when your pump runs, how long it runs, how much water it pumps, etc. then you should buy a manual pump. If you’d rather just set up your pump system and let the amount of  water determine its operation, buy an automatic pump. Generally speaking, our application engineers recommend getting an automatic pump with a piggyback float – you can always detach the float and run the pump manually if you so desire.

Keep in mind that manual pumps also need to be hardwired directly into a control panel.

Top Rated & Best Selling Liberty Grinder Pumps:

Widespread clogging of sewage disposal systems as a result of an increase in the disposal of plastics is causing many to rethink the pumps they choose. And foreword-thinking pump manufacturers are taking note and designing sewage pumps capable of shredding difficult solids that jam traditional solids-handling pumps. This has been happening in the commercial and industrial markets for quite some time, with specialty manufacturers like BJM developing high performance shredder pumps capable of shredding cell phones and sneakers with the ease of a blender whipping a smoothie.

New York-based Liberty Pumps is among the pump manufacturers currently developing high performance grinder pumps for the residential market.

“For years customers experiencing chronic clogging have called asking for a domestic grinder with these specs but there was never anything like it on the market,” says Product Expert Will Perillo. “Liberty Pumps designed the ProVore to operate in a residential setting, providing maximum efficiency and grinding power in a unit that can be plugged directly into a standard 115 volt outlet. We think it’s going to solve a lot of problems.”

In addition to eliminating the rewiring, control panels and electrical expertise required to install a standard 2hp grinder pump in a home, the ProVore features a 2” discharge that provides high flow rates (46 gpm) and allows for direct connection to existing sewer lines.

“Typically grinder pumps have a 1 ¼” discharge which limits flow and makes adapting to existing 2” sewage pumps an issue,” explains Perillo. “ProVore grinders come out of the box with a 2” discharge so there’s no piping adjustment necessary. This makes the ProVore ideal for new construction installations and for upgrading a home’s existing 2” sewage pump.”

We currently offer the following PRG-Series residential grinder pump Models: PRG101M 115V, 12a, Manual; PRG101A 115V, 12a, Automatic; PRG102M 230V, 6a, Manual; PRG102A 230V, 6a, Automatic.

The ProVore 380 is a 1 HP Residential Simplex grinder System designed for basement bathroom additions and remodeling projects. Comprised of a compact heavy-duty polyethylene basin and cover, it can be installed above or below floor level.  Features include a 41 gallon capacity, patented V-Slice cutter technology that shreds difficult solids such as feminine products, rags, towels and wipes that can jam solids-handling pumps, and QuickTree technology that allows easy access and removal of switches without disturbing pump or plumbing.  Ask about the P382XPRG101, 1HP, 115 volt model and the P382XPRG102, 1HP,  230 volt model.

The ProVore 680 is the duplex version of the same system for large residential applications. It has a 46 gallon capacity and contains two pumps to provide secure uninterrupted service, in addition to all of the features of the ProVore 380. We offer 1HP models in 115 and 230 volts.

Liberty has also developed the PDC Series ProVore Duplex Control System to monitor the operation of the ProVore 680. In addition to emitting audible and visual alarms when the system is out of order, it automatically alternates pump operation, equalizing wear and extending pump life.  Ask about Models: PDC-115 115V, for PRG101-Series pumps and PDC-230 230V, for PRG102-Series.


Liberty Omnivore LSG Series Grinder Pumps Rank Best In Class !

 The Omnivore LSG200-series grinder pumps are designed for use in systems that produce high amounts of wastewater. Think motels, apartment complexes, hotels, shopping centers – any type of facility, whether commercial or residential, with high frequency usage and high volume of waste.

LSG200 series pumps are constructed with a sturdy one-piece uni-body cast iron housing, while the impeller is 316 stainless steel. The impeller contains back vanes (or pump out vanes) to better clear solids. The pumps also features dual seals – one unitized silicon carbide, the other Viton double-lip – for extra protection from solids.

Each model uses Liberty’s patented V-Slice cutter to macerate waste solids. The cutter is constructed of hardened 440 stainless steel – Rockwell C 58 and can perform up to 108 alternated cuts per revolution – perfect for turning waste solids into a fine slurry to be collected and transported. This video demonstrates the powerful macerating ability of the Omnivore’s cutter.

The pumps operates at 2 HP and features a 1-¼” discharge. Depending on the model, the pump could operate at 208-230 volts, 208/230 volts, 440-480 volts or 575 volts. Each model operates at either one or three phases of power.

The LSG202M and LSG202A have internal capacitors, so they do not need an external control. The LSG202M-C has an external capacitor so that model requires an additional control panel.

The LSGX-series variations are ideal for multi-unit land developments that share a sewage system, such as apartment complexes. LSGX pumps are similar to their cousins the LSG200, except that they are 2-stage pumps designed for high head applications.

2-stage simply means that each LSGX pump has two stainless steel impellers. The double impellers increase the velocity and can drive the maximum head up to 180 feet.

Both the LSG200 and the LSGX are constructed with the same construction materials, outer dimensions and V-Slice cutter technology. Both series also have the same guide rail configuration. Thus, Omnivore pumps are easily interchangeable within the same basin and guide rail system.

All models in the LSG200-series and LSGX-series come with three-year warranties serviced by Liberty.

Liberty ProVore PRG Series Grinder Pumps Rank Best In Class !

The ProVore PRG-series is expressly designed for use in residential or home wastewater systems. ProVore pumps are equipped with Liberty’s patented V-Slice stainless steel cutter that is capable of turning solids such as plastic bags, feminine products and towels into a fine slurry to be collected and exported.

The pumps are constructed with a cast iron corrosion resistant frame. The motor is oil-filled and thermally protected.

Each model in this series operates at 1 HP, 115 or 230 V, single phase power. The pumps have a 2 inch discharge and can be used as replacement pumps for systems that also have 2 inch discharge lines (that already use LE40 or LE50-series solids handling pumps). Automatic models include a wide-angled float switch with the exception of the PRG101AV which has an integral vertical float switch.

All models in the PRG-series come with three-year warranties serviced by Liberty Pumps.

Zoeller Grinder Pumps That Get The Job Done

Zoeller Gets It Right From the Get Go.Zoeller gets it right from the get go.

The dreaded call back. For plumbing contractors it’s a recurring nightmare. That’s why many of our customers in the plumbing and contracting trades opt for Zoeller Grinder Pumps for applications with chronic clogging issues. Zoeller grinder pumps are engineered to cut through the tough solids that jam ordinary sewage pumps and lead to repeated call backs. The Zoeller grinder pump line ranges from small indoor and outdoor residential systems using a fractional HP grinder, to larger commercial and industrial pumps for applications that require the industry standard 2 HP grinder.

Zoeller’s 915 Grinder Pump System is the industry’s first, 1/2 HP, 115 volt grinder pump for residential and light commercial use. The system was designed for home basements without a gravity sewer that require pumping wastewater up to a municipal sewer. The 915 Grinder System efficiently focuses the torque of a 1/2 HP grinder and 115 volt motor directly on to the cutting surface so that large solids that would clog an ordinary ejector system are easily ground down. Compared to traditional 2 HP systems, this package greatly reduces the initial outlay and annual operating costs of a grinder system.

 For applications notorious for clogging, the industry-leading 840 Shark Series Grinder Pump is specially designed to reverse in direction every other cycle in order to prevent plastic, rope and other debris from getting trapped in the scissor action cutter assembly. As the only single phase automatic reversing pump on the market, the 840 Shark Grinder is the clear choice for light commercial and industrial applications prone to tough clogging. Zoeller maintains a high level of quality by factory testing each pump under water prior to shipping to the customer. This testing ensures that the pump will operate out of the box every time.

Designed, machined and assembled in the USA, Zoeller grinder pumps get the job done right once and for all.
