Submersible Pumps

The most common pump system in our area is the “conventional” submersible pump, where the pump is inside the well, generally 5 to 10 feet from the bottom. The pump delivers water to a pressure tank which is sized to the pump. Once the water pressure in the tank reaches a specific pressure, the pressure switch will turn the pump off. When any water is used in your home, the pressure will decrease until the pressure switch turns the pump back on and the cycle begins again.

Usually there is a pressure differential of 20 PSI. Generally, the pressure switch turns on at 40 PSI and off at 60 PSI, which with a properly sized pressure tank; you will get about a minute of pump run time, which is required in a conventional pump system.

Kellner LLC has always relied on top of the line Gould's GS series submersible pumps for use in a conventional system. We have been installing them for over 30 years. Gould's pumps are designed for residential and small municipal water supply as well as light irrigation applications. They are constructed with a cast 303 stainless steel discharge head and motor adapter, superior sand handling capability, built-in stainless steel check valve, lexon impellers, and a Centripro motor designed for continuous operation. Gould's offers many size pumps ranging from 5 GPM to several 100 GPM.

Kellner, LLC stocks a wide range of Goulds pumps that will fit almost any application so that when you run out of water, we can quickly get you back up and running.Goulds Logo

Jet Pumps

Jet pumps are located above the well, usually in the basement or a well house. With a submersible pump, the water is pushed to the home. It is the opposite with a jet pump. Jet pumps draw a vacuum on the water and draw the water to the pump where the water is pressurized to the home. There are two types of jet pumps:Kellner LLC Well Pumps

  • A Shallow well jet pump has just one pipe going down the well. As the name implies it is just for shallow well applications to a depth of about 20 feet. The deeper the water the harder it is to draw the water to the pump.
  • Deep well jet pumps have two pipes going down the well and they are attached to a device called a jet assembly. The pump forces water down one pipe thru the jet assembly which in turn creates a vacuum drawing water in from the well. The water is then discharged into the water system. The pump uses some of that water to go back down the pipe and continue the cycle. Deep well jets can be used to a depth of about 175 feet. It is important to realize that when the jet pump is replaced that the jet assembly and foot valve, be replaced as well.

If the jet pump sounds as thou it is not very efficient, that's because it is not. Before the submersible pump, the jet pump was better than pumping by hand, but with new technology we have come a long way with efficiently.

We at Kellner, LLC believe that although jet pumps do have a place, a submersible pump is far superior to it. Submersible pumps are quieter, more efficient, cost less to operate, easier to troubleshoot, and in many cases, would be less expensive that a jet pump to install.
