Power units BKA

Compact Hydraulic Power Unit, 700bar

BIERI power units of type BKA are compact heavy-duty power units. They are part of our new power pack concept M.PACK 700 bar. The BKA is lightweight and space-saving by integration of pumping elements into the pump flange. BKA consists of an electric motor, radial piston pump (HP and HP / LP), pressure relief valve, oil reservoir and another components.
Several valves of type WVM and WVH can be assembled directly on the pump flange by the modular conception. In addition the modular blocks of type series M.BLOCK both 700 bar and 500 bar can be combined with the motor-pump assembly.

[Translate to EN:] M.Pack 700 BKA
Features Advantages
Externally mounted motor: Less heating of oil and easier change of motor
Identical interface for electric motors from 0.55 kW up to 2.2 kW: Multiple variations
Multi-functional valve-interface: Enables to mount a single dump valve directly or to implement a valve stack by a flat adapter plate
Design of reservoir of BKA besides the air-cooled motor: Superior rate of the effective volume to the filling capacity
