Pump application:
These positive displacement low inertia pumps are excellent at pumping fluids at medium to high pressures. These pumps can be used to pump water and a large range of other non abrasive fluids including oils and molasses. Very useful for pressure boosting, liquid transfer, factory process pumping and lubrication duties.
Performance data:
Performance curves are based on a kinematic viscosity value of 1mm2/s and a density of 1000 Kg/m3 at 20ºC.
- Flow rates up to 4m3/h.
- Heads up to 140m.
- Fluids must be clean and free from suspended abrasive particles.
- Maximum fluid temperature: +60ºC.
- Maximum ambient temperature: +60ºC.
- Maximum allowable pressure in casing: 15 Bar.
- Rotational speed: 700rpm recommended maximum.

Installation:
Securely bolt the pump unit in location. The gear pump can be installed in any orientation except for engine driven units which must be installed in a horizontal position. However always ensure that the pump is running in the right direction. Gear pumps can run in either direction by operating the power unit in reverse or alternatively by changing the delivery and suction pipes to opposite sides of the pump. If closed heads are to be encountered than a pressure relief or bypass valve must be installed and set to the required pressure. If full bypass is required ensure that the vee belts are correctly aligned with the correct tension. Always prime the pump with the fluid to be pumped and start with a fully open discharge before throttling to pressure requirements.
Caution: Pumps will self lubricate using the pumped fluid however avoid running the pump dry as this will create rapid wear.
