  • Hydrostatic Test Equipment Hydraulic Test Services and Pressure Test Pumps Hydrostatic pressure testing is a critical process in the oil and gas industry, both onshore and offshore, for assessing the integrity and strength of pressure vessels, pipelines, and other equipment used in fluid transportation and containment. Available for rent or for sale, Proserv’s hydrostatic test equipment plays a crucial role in ensuring safety, compliance with regulations, and reliable operation of oil and gas facilities. Hydrostatic Test Equipment Rental At Proserv, we have a comprehensive inventory of hire equipment including electrically driven hydraulic flushing units for mineral oil and water-based subsea control fluids, air-driven hydrostatic test pumps, ancillary equipment, and a wide range of air-driven chemical injection pumps. We have a large fleet of hydrostatic test pumps available for hire, providing a hydrostatic test capability up to 30,000 psi. Pumps range from small hand-operated units to single and double-acting air-operated pumps. With large equipment stocks and logistical support, we can deliver the right equipment to any onshore or offshore location across the world. Our dedicated hire service can also combine hire agreements with modification service and maintenance packages designed specifically to meet your requirements. All our test pumps, gas intensifiers, and flushing rigs are assembled in robust stainless steel frames for both protection and ease of transportation.

  • Flushing Systems and Services Ensure Hydraulic System Cleanliness Flushing systems play a crucial role in the energy industry, both onshore and offshore, for the maintenance and cleaning of hydraulic and lubrication systems. These systems are designed to remove contaminants, such as dirt, debris, and residual fluids, from pipelines, vessels, and other equipment used in the industry. Proserv’s flushing systems ensure the cleanliness, integrity, and efficiency of fluid systems, reducing the threat of equipment malfunctions. Proserv can provide clients with a wide variety of equipment for hydraulic fluid and system cleanliness monitoring and clean-up. Hydraulic System Cleanliness Even under normal operation, modern hydraulic systems generate particle contamination and must be flushed to ensure safe, efficient operation. Generally, newly delivered systems are flushed after manufacture and prior to commissioning to ensure both fluid and system are within specification. This has the advantage of reducing the risk of early failure and consequential warranty claims. Proserv’s flushing equipment ensures that systems are flushed at high velocities through filters designed to pick up the smallest of particles. Proserv can deliver a varied fleet of flushing and hydraulic system cleaning equipment to suit most applications. Designed for cleaning to international standards, these rigs have been specifically developed by Proserv with flow rates from 5 to 34 litres per minute. All units accommodate standard mineral-based hydraulic fluids, and special units are available for synthetic and water-based fluids. Fully certified ATEX units are available for hazardous area (Zone 1) operation as well as normal industrial use. Proserv can also supply AS4059 and NAS 1638 compliant automatic particle counters to ensure that hydraulic fluids and systems contain the minimum amount of solid particle contamination. These can be employed on-site where mineral or synthetic hydraulic fluids are used and a physical count is required. These devices can instantly define the number of particles found in a single fluid sample, within the set ranges of between 5 and 100 microns. Proserv can manage the cleanliness of existing, recently installed, and newly manufactured hydraulic systems, or rent out the equipment, enabling suitably qualified clients to undertake the work themselves.
