Page 7: General Description
Introduction General description Danfoss Series 45 E frame open circuit piston pumps convert input torque into hydraulic power. Rotational force is transmitted through the input shaft to the cylinder block. The input shaft is supported by tapered roller bearings at the front and rear of the pump and is splined into the cylinder block . A lip- seal at the front end of the pump prevents leakage where the shaft exits the pump housing. -
