Catalog excerpts

Hand pumps type PM 2-plunger PM are double alternate-acting hand pumps with simple and rugged construction for minimum service and long operating life. They are provided with one by-pass valve ᕃ which connects directly the delivery ports with the inlet port through the delivery valves ᕄ. The by-pass valve is operated by a handwheel ᕅ. Pumping operation is made by alternative movement of the lever ᕆ and consequently movement of plungers ᕇ, after having locked the by-pass valve by means of the handwheel. The splined shaft attachment ᕈ permits to turn the lever shaft in the best position. On the pump body are available two outlet ports (one supplied plugged). Suitable for hydraulic oils according to DIN 51524…535 or synthetic fluids having similar lubricating characteristics. Displacements: from 6 to 20 cm 3 for double stroke. Max pressure 500 bar MODEL CODE Seals material: omit for NBR (mineral oil & water glycol) PE = FPM Displacement, see section ‫ݘ‬ 106 = 6 cm3/double stroke 112 = 12 cm3/double stroke 120 = 20 cm3/double stroke Series number OPERATING CHARACTERISTICS with hydraulic fluid having a viscosity of 24 mm2/s and 40°C Displacement for double stroke [cm3] Shaft rotation angle [degree] Maximum torque required [Nm]

MAIN CHARACTERISTICS OF HAND PUMP TYPE PM Installation position Commissioning Ambient temperature Fluid Recommended viscosity Fluid contamination class Fluid temperature Vertical position, with inlet port facing upward to ensure complete case filling Pumping operation is made by alternative movement of the lever after closing by-pass valve. Note: the by-pass valve connects the delivery ports with inlet port and when locked it could allow some leakage from outlet ports. Two opposite outlet ports are available for pump delivery: one of these is supplied plugged. The pumps are supplied without...
