General Information
Description
The model 30000-S DHPU is an open frame type power unit designed to provide hydraulic
power to an open center circuit such as a casing tong, tubing tong or other open centered
circuits. The unit is self contained.
The DHPU is powered by an air cooled, 6 cylinder Deutz diesel engine. Attached to the
engine is a two section gear pump. Both sections provide fluid power for the casing circuit.
When the tubing tong circuit is active, fluid power only comes from one section of the gear
pump. There is an auxiliary hydraulic pump mounted on the engine to provide power for the
heat exchanger motor. Also included within the unit are the following items.

Instrument panel with engine speed, oil temperature and oil pressure
