Notes
- R=Clockwise, L=Counter-clockwise (viewed from shaft end); 05: standard shaft extension, 01: alternative shaft type; 11N/10N=NBR nitrile seal; 11W=FKM fluororubber seal, high temperature resistance and compatible with fire-resistant hydraulic fluids.
- Flow value is theoretical flow at 1500rpm; IGP internal gear pumps achieve much higher volumetric efficiency than GP external gear pumps and maintain stable output flow at low speed.
- IGP5 can be assembled as multi-stage pumps. For multi-combination assembly, pumps shall be connected in descending order of displacement. Can be combined with IGP3/IGP4/IGP6 to satisfy independent oil supply for multiple circuits, widely used in servo hydraulic systems.
- Avoid additional external radial and axial loads on pump shaft. Elastic coupling is recommended for driving.
