Low speed radial piston hydraulic motor NHM31

Model: NAM31 Series


Replace for: Hagglund NHM
Series,Denison,
Intermot


Displacement: 213-10019 ml/r


Torque: 935-36667 N.m







NAM series bent
axle connecting rod type motor has such characteristics as: high mechanical
efficiency and good reliability, thus it 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.






Features:




1. As the product adopts eccentric crankshaft and five-piston structure
with comparatively low frequency, it has low noise characteristic;

2. It has big startup torque, perfect stability at low speed, so it can
stably operate at very low speed.

3. The patented plane compensation port plate has perfect reliability and
almost no leakage. The piston bushing is sealed by seal ring, so it has
comparatively high volume efficiency.

4. The crankshaft and the connecting rod are supported by roller, so it
has very high mechanical efficiency;

5. The rotational direction is reversible, the output shaft allows endure
certain radial and axial force;

6. It has comparatively high power mass ratio.
