KLW4000N Series Hydraulic Torque Wrench Pump-Pneumatic Operation

KLW4000N Series Hydraulic Torque Wrench Pump-Pneumatic Operation

KLW4000N special pump adopts the integrated method for hydraulic spanner, the oil pump, control valve, fuel tanks, pneumatic motor, cooler, such as instrument of a kind of independent complete hydraulic device, has small volume, light weight, simple structure, convenient operation, high working pressure, etc. The pump is high and low pressure oil pump, can obtain the larger output oil. When high pressure, the low pressure pump is automatically returned to oil by unloading overflow valve and can reduce the power consumption, and (A) the oil pressure can be adjusted anywhere from 70 to 700 bar.


Product characteristics

Use where air(4-8 bar)is the preferred.
Compact power there stages flow design.
