Selecting a Pump for Groundwater ApplicationsJanuary 2, 2019
As long as gravity exists, people will need pumps. If your application requires the pumping of groundwater, making sure you have the right pump for the job is essential. Using a pump that is incorrectly sized for an application can lead to damages in equipment and your wallet. The first thing to keep in mind is the type of fluid you intend on pumping. Is it clear water or water, such as grey water, that is mixed with solids such as dirt and silt The material you’re pumping can drastically change the model of pump you need. If you do expect solids, make sure your pump is suited for solids handling. Next you’ll need to figure out how far exactly and where the water is going to be pumped. Knowing this will help you determine the required total dynamic head (TDH) and flow rate of your application, which are key factors when picking a pump. Total dynamic head refers to the total resistance in a pumping application. To calculate the required total dynamic head, you will need to figure out two factors: vertical rise and friction loss. Vertical rise is how high your water will need to travel before gravity takes over. Friction loss is the loss of flow in a system due to friction created by factors like pipe type or fittings. You can follow this guide for more information on calculating TDH. Once you know the TDH, you will need to figure out the total distance the water needs to be pumped, or how far from the source of the liquid to its ultimate destination. This will help determine your flow rate, or the velocity of the liquid traveling within a certain amount of time (usually measured in gallons per minute). Once you know your specifications, you can refer to a pump curve chart to see if that model of pump will work for your application. Pump curve charts are a helpful tool in figuring out what a pump is capable of and in mapping out their efficiencies over various specifications. You can find these charts on PumpProducts.com, which are usually located in a pump’s brochure under the manuals tab on our product pages.

What is a Jet Pump?November 14, 2018
Believe it or not, jet pumps are not associated with the awful New York football team. They are referred to as such because they work similarly to a jet engine in the way they create large amounts of pressure. Jet pumps are mounted above ground and are non-submersible. They are typically used to draw water from a well through a suction pipe in order to provide potable water or domestic water pressure. Other common applications (though certainly not limited to) include light commercial or residential irrigation and supplying water for sprinkler systems. Jet pumps are typically more popular in warmer climates or areas with high water tables. Jet pumps come in two variations: deep well and shallow well. The type of jet pump most suitable for your application will be dependent on the depth of your well. Shallow well jet pumps are used to transport water from wells as deep as 25 feet. Deep wells are generally used for depths up to about 200 feet. Deep well jet pumps can move larger volumes of water more quickly and over longer distances than shallow well pumps. Please note that altitude can affect the specific depth to which a pump can draw water from. Deep well pumps can also be referred to as convertible jet pumps. This means that the pump can be used in either shallow or deep wells. In a shallow well setup, an ejector kit (or jet kit) is built in or attached to the pump. For deep wells, the kit is placed down in the well. This ejector kit helps force water up from the bottom of the well. If you already have a jet pump and you are looking to determine whether it is a deep well or shallow well pump, look at how many pipes are between the pump and the water source. One pipe indicates a shallow well pump while two pipes indicate a deep well pump. It is important to keep in mind that jet pumps should never run dry. Running a pump dry may significantly and permanently damage the pump. Jet pumps need to be primed first before they are ready to draw water. In order to prime your jet pump, first make sure the electricity to your pump is off. Next remove the priming plug on the wet end of the pump (or the side opposite the motor). Then fill the priming vent with water until it reaches the top of the vent. The idea behind this is to remove all the air from the pump housing. After the pump is primed, your pump is ready to go and you can turn the electricity back on to the pump. If the pump does not pull water within five minutes you may need to re-prime the pump.

Why is My Submersible Well Pump Short Cycling?May 8, 2018
Welcome back to another edition of Inspector Pumphead’s Quick Tips! In this space I, Inspector Pumphead, will be dispensing wisdom regarding your pump, whether it be about performance, maintenance, repair parts or navigating our site to find a new product, I’m here to help! Today we’re going to be talking about short cycling. Is your pump turning on and off so fast it’s bringing you back to your strobe light-disco days, complete with afros and bell bottoms No Just me Sometimes the Inspector likes to think back to simpler times when he had a full head of hair. But I digress. Let’s talk about some common causes and fixes for your short cycling submersible well pump. Short cycling is when a pump turns on and off too rapidly. Not only can short cycling result in pump failure, but it can harm the rest of your system as well. Short cycling can occur for a number of reasons. One of most common reasons for short cycling is a loss of air in the water pressure tank. This is especially common in older, non-bladder pressure tanks. For these older tanks, the solution to this problem entails repairing the water tank air volume control. If you have a more modern tank, your tank’s bladder may be damaged, which means it won't be able to hold pressure properly and will need replacing. If the tank is damaged in any way, replacing it as soon as possible should be a priority so the rest of your system doesn't become stressed. Short cycling can also occur because of the state of some of your pump’s components such as the pressure switch and check valve. You will want to examine these parts for wear and tear as they may be the culprit. The settings on your pressure switch may need to be readjusted or the switch could potentially need replacing if damaged. Your pressure tube may be clogged due to hard water or sediment in the system so this is something to check as well. A failed check valve means your system will not be able to hold pressure when the pump shuts off, which means this part may also need replacing. If you've tested your pump's components and they are in working order, something as simple as a leak in your system may be responsible for your pump's malfunctioning. It's important to look for damp spots around your system. If you are still unsure of the problem, or which repair part you need, you can always consult and schedule an appointment your local plumber or professional.

What’s the Difference: 2 Wire vs 3 Wire Submersible Well PumpsApril 17, 2018
Welcome back to another edition of Inspector Pumphead’s Quick Tips! In this space I, Inspector Pumphead, will be dispensing wisdom regarding your pump, whether it be about performance, maintenance, repair parts or navigating our site to find a new product, I’m here to help! This week we’ll be talking about the difference between 2 and 3 wire submersible well pumps. Firstly, both types feature a ground wire which shouldn’t be counted. Two wire pumps will have 2 black wires and a green wire. Three wire pumps have a black, red, yellow, and green wire. Let’s dive in and figure out which one is right for your application! The main difference between 2 wire and 3 wire well pumps is characterized by where the starting components for the motor are located. Three wire well pumps house the starting components (starting capacitors, running capacitors, relays, and thermal overloads) in a control box or panel. Control boxes are usually mounted on a wall above ground. Though the potential of failure for the parts is greater than a two wire system, the components can be easily accessed and cheaply repaired or replaced. For example, if a capacitor malfunctions on a three wire, just the capacitor itself will need to be replaced. Two wire well pumps do not use a control box. All the elements already come built within the motor or pump house itself. This allows for easier installation. However, if any of the starting components fail, the pump will have to be pulled up and the whole motor will have to be replaced. The likelihood of component failure in a two wire system is much lower than a three wire, although it is a much more expensive and time consuming endeavor if a part does fail. At the end of the day, it’s up to you to determine the more convenient approach for your application. Your circumstances may dictate one configuration over the other. Keep in mind, motors that are more than 1.5 HP requires a three wire configuration and a control box to start the heavier motors.

Five Telltale Signs You Need Well Pump ServiceJune 21, 2016
Over 43 million Americans still get potable water from a private well according to a U.S. Geological Survey study - roughly 15 percent of the population. The well pump is thus one of the most important day-to-day tools for many Americans and well pump service is a critical need. The responsibility for maintaining a private well system thus falls to whoever owns the property the well is situated on. It can be a headache for a private homeowner with no technical expertise to understand and address maintenance issues as they crop up. Well pumps come in various types: shallow well jet pumps mounted above a well use suction power to create atmospheric pressure that pushes water up from a source no more than 25 ft. underground. Deep well jet pumps, for pumping from a source more than 25 ft. underground, place the jet mechanism at the bottom of the water source; the jet pushes and pulls water in a circulating motion through a two-pipe system. In a submersible well pump system, the entire body of the pump is placed underwater and pushes the water up the well instead of using suction. These compact pumps are generally more efficient and reliable than older jet pump models. Each type of well pump has its strengths and weaknesses, but they all require consistent maintenance. People who get their potable water from municipal systems probably have the luxury of not thinking about pumps. If you draw your potable water from a well, you must remain vigilant about the problems you could face. That means being watchful of certain symptoms that could indicate your well pump might need maintenance or replacement. The following are some of the most common symptoms that cause customers to consult Pump Products technicians. [This post is meant to be a basic overview. It is not a comprehensive how-to manual or a call to poke around in your system. Please do not hesitate to contact the trained professionals at Pump Products to directly address specific issues. It is recommended that all electrical work be handled by a qualified electrician.] (more…)
