The NHM70 Series PisTon Hydraulic Motor is produced according to ltalian standards but in consideration of actual situations of China. The main parts and components are machined by machining center and CNC machine tools.
All the seal parts and high strength interior hexagonal bolts are imported from Germany, Italia and Taiwan. The casting is made of polyester sand nodular cast iron to ensure the performance and appearance quality of the products to overpass the similar products in China and overseas market.
This The NHM70 Series PisTon Hydraulic Motor can be widely applied in hydraulic and transmission systems of plastics machinery, light industrial machinery, heavy type metallurgical machinery, petroleum and coal mining machinery, lifting and transportation equipment, ship's deck machinery, geological prospecting equipments, etc.
1. Low noise due to an eccentric crankshaft and low excitation frequency of five-piston design;
2. Revolve steadily under very low speed due to high starting torque and good low-speed stability;
3. Good reliability and less leakage due to the patented flat compensation distributor, spcial sealing between piston and plunger bushing guarantees higher volumetrically efficiency;
4.High mechanical efficiency due to roller bearing between crankshaft and connecting rod;
5.Reversible rotation, and the output shaft can bear certain external force from both radial and axial direditons;
6.High power-mass ratio, small volume and light weight.
7.The mounting dimension and more than 80% of internal components can be interchanged with The NHM70 Series PisTon Hydraulic Motor.
