Hydraulic power packs type MPN and MPNW
30Pages

Hydraulic power packs type MPN and MPNW for the short time, on/off- and intermittent operation Operating pressure pmax = 700 bar (radial piston pump) Flow Qmax = 139 lpm (gear pump) Design and general information For additional information see: Hydraulic power packs type MP type HK type A Connection blocks type B type C Directly mountable valve banks type BA Valve banks Directional seated valves type VB Directional seated valves type BWN, BWH Directional seated valves type BVZP type NE Two stage valves type CR Pressing tax valves The compact hydraulic power pack serves to supply pressurized fluid for intermittently or short-term operated hydraulic circuits. The basic hydraulic power pack consists: o Tank (available in different sizes) o Drive motor (available for different voltages and power requirements) o Radial piston and/or gear pump directly driven by the motor shaft The compact style obtained with this design represents an essential advantage opposite conventional units. Complete turn-key solutions can be easily arranged via a wide range of connection blocks (see D 6905 ++) and directly mountable valve banks. There is a wide field of applications for theses compact power packs within tool machines, jig assemblies and general mechanical engineering. Versions - Single circuit pumps (radial piston or gear pump) - Dual circuit pumps High pressure - High pressure (H-H) High pressure - Low pressure (H-Z) - Tank or cover plate version Electrical connection - 3+ or 1+phase Operating ode The pumps are rated for use in short time and on/off service S2 and S3. Intermittent service S6 is possible as long as the tank has a sufficient size (dep. pump size and load).
