The pressure control pumps L5-4S and L7-4S, are designed to provide a pressurised water supply at good flows from a break tank.  Each pump unit is fitted with a control system which combines both flow and pressure switch activation, making it a completely automatically operated pump.

Ideal for pressurisation of either hot or cold water services in commercial applications, these units are easy to use and install.
