What Are the Benefits of Constant Pressure Well Pumps?

Constant pressure well pumps, also known as “city water pressure” pumps, offer many advantages over older mechanical systems that simply send water at a fixed pressure level to a storage tank every so often, a process known as pressure cycling. According to Environmental Equipment & Supply, a constant pressure pump constantly monitors and adjusts the water pressure it sends through the well system. This more precisely controlled operation prevents equipment clogs and failures while giving users a consistent, reliable water supply.


Constant pressure well pumps offer greater control over water pressure from wells to delivery sites.

Constant pressure well pumps have a more efficient, sophisticated design than those found in older systems. An electronic pressure controller takes continuous water samples to determine the pressure of the water as it moves through pipes. It relays this information to a microprocessor, which in turn sends signals to the pump motor to speed up or slow down as necessary. Well operators can set the system to whatever pressure level their everyday applications may require.


A well equipped with a constant pressure pump will provide a more consistent, uniform supply of water than a well equipped with a conventional pump. Conventional pumps run on a motor that operates at a constant speed, pumping water into a bulky storage tank at regular intervals, regardless of the actual level inside the tank. This action may result in too much or too little water at any given time. A constant pressure pump’s ability to precisely control its output ensures that critical applications will always receive no more or no less water than they require.


A constant pressure well pump can sidestep some of the operational problems associated with conventional well pumps. For example, when a conventional well must run constantly to irrigate crops or feed lawn sprinklers, its system of on-and-off pressure cycling can stir up excess silt, which then clogs the pump. Pressure cycling also puts the equipment under unwanted stress from shearing forces every time the system engages. A constant pressure well pump can do its job with less force, avoiding clogs and other equipment failures.

Cost Efficiency

Constant pressure well pumps can save owners and operators money in several ways. The initial installation tends to cost less for these pumps than for standard pump systems, despite the more sophisticated controls. Unlike conventional pump systems that call for the purchase of a large, expensive storage tank, some constant pressure pumps can run on a tank with a capacity of only 4.8 gallons, according to the Dean Bennett Supply Company. Since the more efficient operation of these pumps also puts less stress on other equipment over time, owners may get more life out of their well components while spending less on repairs and maintenance.
