Proserv is an industry expert in flushing and hydraulic pressure testing services with over 30 years’ experience both onshore and offshore. We have designated testing facilities for hydro testing (0 to 40,000 psi) and gas testing (0 to 30,000 psi). Our products range from small test pumps to complete test and flushing systems for liquid or gas usage. We offer customers test and flushing product options ranging from a bespoke solution to a prefabricated test unit for immediate usage.

We provide our clients with safe operating systems for the pressure testing of assemblies and components, and remotely controlled test systems allowing hydraulic flushing and testing to be controlled within a safe environment.

Proserv provides a comprehensive range of electrical driven mobile flushing units, including zone rated units for onshore and offshore applications. All our units are suitable for use with mineral and synthetic oil and water-based glycerol fluids for subsea hydraulic control lines. Our high-pressure mobile pumps range consists of high pressure mobile hydrostatic pumps with pressure testing, chemical injection, valve actuator control, hydraulic cylinder actuation and hydraulic power with pressure output capability of up to 21,000 psi. Proserv has extensive experience in providing testing services for subsea equipment. Tests can be conducted to national, international or industry standards or to the client’s own enhanced test specification. At our purpose-built test facilities, we can undertake testing including hydrostatic/gas testing, high pressure testing, site integration testing (SITs) and factory acceptance testing (FATs).

Our team of fully trained and experienced technicians ensure equipment is maintained to the highest possible standard with the appropriate certification.
