World Chemical GV Self Priming



Self-Priming Magnetic Drive Pumps

The GV poly-propylene self-priming magnetic drive pump range is ideally suited for a wide variety of applications. The compact and powerful design and manufacture of the GV units means a 5-metre suction lift can be achieved in 2 minutes. The GV range can be used with long horizontal & vertical suction pipework and is ideal for emptying tanks without a bottom outlet e.g. iso-tankers.

Internationally patented valve-less design ensures air release and a siphon break when the unit stops. This means that liquid remains in the auxiliary tank and no further priming is required. A unique rotating flange design allows easy connection & installation. Minimum maintenance and all parts can be replaced individually.

Compatible with hazardous liquids, carbonated liquids with potential for air lock and liquids with a high specific gravity.

The GV range offers transfer volumes up to 25m3/hr and is fitted with a standard IEC motor frame for compatibility with a wide variety of motor options.
