GPL4 series hydraulic oil pump manufacture

   GPL4 series gear pump is a new generation 25MPa-class hydraulic power components self-developed successfully by the company to adapt the present middle and high pressure host system with displacement range from 80ml / r to 160ml / r

Based on the computer programming and finite element analysis technology to choose the best design parameters, to improve the use pressure of gear pump, reduce operating noise, and maintain long-term steady pressure and high output efficiency.

Using a special needle bearing technology and imported high-strength cast iron housing to improve the gear pump life and impact resistance.

It can form a tandem pump used for all kinds of hydraulic systems in engineering machinery, mining machinery, metallurgical machine.

 

 

Advantage:

1,Monolithic structure, use the pure radial fluid pressure on the low voltage side of local equilibrium technology and nodular cast iron pump body and double row needle roller bearings, coating,multiple pump in series is available.

2,The front cover can be divided into two parts: installation flange and front cover.The front cover is commonality parts,it can adapt to a wider range.

3,Patent technology, double row needle roller bearings, coating side panel, and pump body guarantee cost is more competitive than rivals.
