Hydro Pneumatic System

Hydro Pneumatic System

The hydro pneumatic system consists of a pressure pump and a pressure tank. The pressure tank consists of a rubber bladder surrounded by pressurized air.

A hydropneumatic tank contains pressurized air and water. It does not have a bladder and air is in direct contact with the water. The compressed air acts as a cushion exerting or absorbing pressure. This type of tank serves three main functions

  • Delivers water within a selected pressure range so the well pump is not continuously running.
  • Prevents a pump from starting up every time there is a minor call for water from the distribution system.
  • Minimizes pressure surges (water hammer).
