HRP
Hydraulic Power Unit

Advance, Intelligent and Compact all in one package that is field proven, tested and improved for over 33 years.
Features & Benefits
HRP's Hydraulic Power Unit (HPU) is a compact, intelligent and advance all in one package that includes the hydraulic pump, prime mover, hydraulic valves, cooling system, oil reservoir, motor controller and PCL pump controller on a bunded skid. 

Our HPU is designed with simplicity, robustness and trouble-free in mind. We've been improving on our design over the last 33 years and had incorporated the latest innovation in hydraulic technology. Our HPUs are capable of single and dual-well operations, and had been field tested and proven to outperform and outlast competitors. We welcome challenges and thrive on engineered and customized solutions, there is no application too difficult for us.

HRP Hydraulic Power Unit

Cooling System

The cooling system consist of an air over oil heat exchanger and is sized in accordance to the horsepower rating of the prime mover. The cooling system keeps the hydraulic oil cooled at all times to ensure maximum performance and reliability. 

Motor Control Panel & PLC Pump Controller

The HRP power unit is an all inclusive package that integrates the motor control panel and PLC pump controller into one compact unit. The PLC controller comes with an integrated cellular modem with wifi capabilities. 

Hydraulic Reservoir & Control Valves

All of the hydraulic valving system and sensors are contained above the hydraulic oil reservoir, where any leak (if any) is flowed back to the oil reservoir, ensuring that no spills and leaks out of the power unit.  

Prime Mover

HRP's prime mover comes standard with an electric motor with gas and diesel engines as optional. 

Hydraulic Pump

The hydraulic pump comes in 2 versions, a vane pump or piston pump and is selected based on application.

Features & Benefits

All in one compact & semi-mobile

HRP's HPU is truly an all in one plug and play package. The HPU consist of the prime mover, hydraulic pump, valving and sensor system, cooling system, PRL control panel and pump controller. Smaller units can be transported in a pickup truck and lifted with a forklift. 

Hydraulic Oil Leak Containment

All of the hydraulic valving system and sensors are contained above the hydraulic oil reservoir, where any leak (if any) is flowed back to the oil reservoir, ensuring that no spills and leaks out of the power unit.  The HPU is available with spill pans, offfering secondary containments. 

Low Sound Emission and Sound Attenuation

HRP's HPU runs quietly and efficiently. For highly noise sensitive areas a sound attenuation enclosure option is available. 

Low & Easy Maintenance

Decades of experience, feedbacks from producers and R&Ds had resulted in our engineers developing HPUs that are easy to maintain and repair. 


Our units are used in some of the most isolated and sensitive areas where regular breakdowns are not tolerated.
