Hydraulic Power Unit (HPU)

• Electric-drive HPU – Ex d motor-driven pumps, duty and standby, where site power is available.
• Air-driven HPU – pneumatic pumps for hazardous areas or sites where instrument air is the only utility.
• Wellhead and HIPPS HPU – accumulators sized for stored energy so valves close on loss of power or supply.
• Intensifier HPU – for pressures above 10,000 psi, using intensifiers on the high-pressure circuit.
• Test bench HPU – for workshop testing of actuators, valves and hydraulic components.
• Skid, cabinet or containerised build – open skid for sheltered areas, stainless cabinet for outdoor service, or container for a self-contained installation.

• High availability – duty and standby pumps keep pressure available during pump maintenance or failure.
• Energy on demand – accumulators sized for stroke volume and stored energy complete valve strokes without the pumps running.
• Clean hydraulic fluid – pressure and return filtration to the ISO 4406 target protects valves and actuators.
• Corrosion-resistant reservoir – SS 316L reservoir with level, temperature and breather.
• Stable operating temperature – the cooler keeps fluid within its working range in continuous duty and hot climates.
• Early warning – local control panel with alarms and remote signals to the plant control system.
• Safe by design – pressure control and relief valves, engineered to ISO 4413 hydraulic safety practice.

Pressure: up to 10,000 psi; higher with intensifiers | Flow: to the application | Reservoir: SS 316L | Cleanliness: to the ISO 4406 target | Drive: electric (Ex d) or pneumatic

ISO 4413 hydraulic fluid power safety; ASME B31.3 tubing; IEC 60079 hazardous-area equipment.

• Designed in Canada, built in India – engineering from Vaughan, Canada and manufacturing in Chennai, India give you international design quality with competitive pricing and lead times.
• Built to your specification – we engineer to your P&ID, data sheets and company standards, and submit GA drawings and 3D models for approval before fabrication starts.
• Proven in demanding service – our high-pressure Inconel 625 sampling stations have been supplied in series to Saudi Aramco refineries, and our lab, pilot and skid systems are used by national laboratories, universities and industrial R&D teams.
• Traceable quality – PMI, dye-penetrant and hydrostatic testing as specified, EN 10204 3.1 material certificates, and NACE MR0175 / ISO 15156 materials for sour service.
• Witnessed FAT and full documentation – factory acceptance testing with you or your third-party inspector, and a complete documentation dossier with every unit.
• One point of responsibility – engineering, fabrication, testing, installation support, commissioning, operator training and spares from one supplier.
• For this product: pumps, accumulators and filtration sized to your actuator stroke volumes, duty and cleanliness target, with duty and standby redundancy.

Engineering to your P&ID, data sheets and company standards; drawings submitted for approval before manufacture; factory acceptance testing (FAT) with client or third-party inspection; export packing and full documentation dossier; installation support, commissioning, SAT and operator training; spares and after-sales support worldwide.
