Deep Well Piston Pumps

Air Pump In this case, an air-pump air-release type of control will be needed. With this type of control, instead of air being supplied to the tank only when needed, air is supplied continuously while the pump is operating. When the water level is high and more air is needed, the float rides high in the tank and keeps the float valve closed. This allows the incoming air to remain in the tank. When too much air accumulates in the tank, the float rides low enough to keep the float valve open and allow air to escape into the outer chamber of the control.

A pressure valve in the outer chamber keeps too much air from escaping when the tank pressure is below 30 pounds with a pressure-switch setting of 20-40 pounds.
