HYDRAULIC POWER UNIT
HKB (CE + ATEX EXPLOSION PROOF) power units
Since the introduction of the HKB35 and HKB66, NOV has
continuously worked towards improving the efficiency, reliability
and safety of its design. This expanded product range will
respond to the industry demands for reliable easy maintenance
power units built according to ATEX-rules (Explosion Safety)
for safer operation.
HKB FEATURES
•
•
•
Variable displacement piston pump, stops the flow at
maximum pressure to prevent unnecessary heating up
of the oil.
A power compensator is mounted to prevent an overload
of the electric motor
Automatic temperature control. The cooler starts
automatically at an oil temperature inside the tank of
38ºC (100ºF). The unit automatically shuts down if the oil
temperature inside the tank reaches 70ºC (158ºF)
• Automatic oil level safety. Unit automatically shuts down if
the oil level inside the tank is too low.
• Pressure and return connections by with quick disconnect
couplings
• Electric powered
• Skid mounted unit unit van be lifted using a forklift or
crane
• HKB units can be lifted using a forklift or a crane.
