DUPLOMATIC IGP3 Internal Gear Pump
Product Features
IGP3 is a fixed-displacement internal gear pump adopting axial + radial pressure compensation structure. Compared with external gear pumps, it features low noise, small flow pulsation, high volumetric efficiency and excellent low-speed performance, capable of continuous long-time operation under high pressure. It supports single pump and multi-section tandem combinations (IGP3+IGP3 / IGP3+IGP4).
- Displacement range: 3.6～10.2 cm³/rev
- Continuous working pressure: 330 bar; Peak pressure: 345 bar
- Max speed: 3600 rpm; Min working speed: 400 rpm
- Mounting flange: SAE J744 standard flange; Port: SAE J518 flange-type oil port
- Recommended hydraulic oil: Mineral oil, viscosity 25～100 cSt, oil temperature -20～+90℃
- Seals: NBR nitrile seal (11N/10N); FKM fluororubber seal (suffix W, for fire-resistant hydraulic oil)

Notes
- R=Clockwise, L=Counter-clockwise (viewed from shaft end); 05/01 represent different shaft extension specifications; 11N/10N = NBR nitrile seal; 11W=FKM fluororubber seal, compatible with fire-resistant hydraulic oil and high-temperature working conditions.
- Flow rate is theoretical value at 1500rpm. Internal gear pumps have high volumetric efficiency with far less actual flow loss than GP external gear pump series.
- IGP3 can be manufactured as multi-stage pumps, and can be combined with IGP4/IGP5 to form double/triple pumps for independent oil supply of multi-circuit systems.
- The pump shaft should avoid external radial and axial additional loads. Elastic coupling drive is recommended.
