Description
Wennstrom • Gear pump with a mechanical pressure relief valve • DN100 (4″) 700-2000 L/MIN
High reliability and robust design combined with active product development have given the Wennstrom fuel gear pump a genuinely good reputation. The pump has been developed to meet the most varying installations and demands.
Many applications
The fuel gear pump is mostly used within the petroleum distribution industry but has also, thanks to its versatility, found many other industrial applications.
It can be configured in eight different ways which simplifies installation and pipe layout. The pump can be powered directly linked to a truck PTO. For truck and PTO installations the pump can be extended with a hydraulic pump to supply other power consuming equipment.
Mechanical pressure relief valve
To achieve the most optimized and safest working conditions the pump pressure can be set between 1.5 and the maximum permissible 10 bar. This spring loaded version is suitable for fixed installations with stable working conditions pumping a liquid with uniform viscosity. The pressure is set by adjusting the tension of the relief spring. Normally the pressure can be set between 4 and 10 bar.
Shaft seal
A well proven design with both teflon and graphite parts combined with teflon impregnated cotton braid. The seal is lubricated by the pumped liquid and can easily be tightened up which gives a very long life span. When required the seal is easily dismantled and new parts fitted.
Assembly configurations, flow and rotation directions
The three flange connections of the pump can be used as either in- or outlet and there are two possible shaft positions giving in total eight different assembly possibilities. Configurations one to four have a low fitted main shaft and five to eight come with the top placed shaft.
