Product details

Rural customers usually rely on wells to supply their water. Pumps are used to bring up the water from the well and to pressurize the water pipes in the home. Water is pumped into a storage tank to compress an air bladder that exerts pressure on the water in the home. When the desired pressure is reached, the pump must be stopped. This is where the pressure switch opens a set of electrical contacts to stop the pump. As your customer uses water, the pressure in the storage tank falls. When the lowest desired pressure is reached, the switches close to start the pump and recharge the system pressure. The most common water pump pressure settings are 20 to 40 pounds per square inch (p.s.i), 30 to 50 p.s.i. or 40 to 60 p.s.i. The high number is the cut-out pressure. Match replacement pump to pressure settings of an existing system for replacement.
