Filter Pumps

These pumps are operated on water or compressed air, and produce a satisfactory vacuum, even when the water (or compressed air) pressure is low, i.e. it requires little water (or compressed air) for its operation. The fact that the pumps are fitted with a NON RETURN VALVE ensures the maintenance of vacuum. even when the water (or compressed air) supply is interrupted.
