Water System Pumps & Parts

A pressure pump is an essential part of any household water system, that is not connected to a water utility service. Typically, a pressure pump will be used to pump water from your holding tank to the rest of your water system. Some water systems may require more than one pump (a deep well pump or a transfer pump, for filling the holding tank), while other systems may do well with just the pressure pump.

Properly designed systems will also include an inlet filter, to protect the pump from waterborne debris. We carry a variety of Flojet inlet strainers. The U.S. 40 Mesh strainer screen will block any particle larger than 0.0165 inches (420 microns) from entering the pump, and the transparent covers allow quick visual inspection of the filter screen. You can remove the cover to easily rinse any debris out, if it becomes clogged.

Most water pressure pumps should also be used with an accumulator/pressure tank. Unless you purchase a variable speed pump (like the Flojet R4525), an accumulator tank will help reduce pump cycling, and sudden changes in water pressure ("chatter" or "water hammering") in your pipes. An accumulator tank is installed after the pressure pump and matched to the pump's pressure switch settings, to hold a small reserve of pressurized water to supply a smooth, constant flow of water.
