Pump Solutions have been agents for Vimpi, supplying gear pumps, hot oil centrifugal pumps, valves and other ancillary equipment since 1999.
The pumps are able to handle both very thin and viscous liquids up to 2,000,000 SSU. They can also achieve capacities of up to 120m³/h and temperatures up to 400°C.
The pumps are available in general purpose bareshaft or heavy duty bracketed (K model) configurations and can be supplied with internal relief valves to prevent damage to the pump or system.
Materials of construction include cast iron, bronze, steel and stainless steel. Bushes are also available in carbon graphite and tungsten carbon, dependent on application.

Operating Principle:
Internally the pump has two gears and a crescent. The rotor (large gear) is driven by the motor and drives the idler gear. As the gears unmesh, liquid is drawn into the pump (1). The crescent separates the liquid and acts as a seal between the rotor and the idler (2). In (3) the pump casing is full of liquid. As the gears mesh (4) the liquid is forced out of the discharge port. This action gives continuous non-pulsating flow.
Operating Principle:
The external pump also has a drive gear (driven by the powers source) and a driven gear. The gears run in opposite directions (1) and the liquid carried around the outside between the gears and the casting (2). As the gears re-mesh on the discharge side, the liquid is forced out into the discharge line. The action gives a continuous non-pulsating flow.
