Flowplant manufacture a range of high flow hydrostatic test rigs. We specialise in building units that combine a fast filling function with a final high pressure test. This often requires integration of several different pumps onto a single skid. Our hydrostatic test rigs often have a high flow centrifugal pump for quick prefill, a triplex plunger pump for a medium pressure test and possibly an intensifier for a final high pressure test.

Adopting this integrated approach can provide, for example, a unit capable of 10m3/hr at 10 bar all the way up to 200l/hr at 2,000 bar. If pressure control needs to be monitored, adjusted or recorded from a remote location we can offer solutions to cover all aspects.

The Flowplant range of fast fill and test rigs have been deployed on many sites and vessels in the last 30 years where our Aqua triplex pump and Harben radial diaphragm pumps have operated reliably and economically. It is common for such systems to use sea water for testing and Flowplant has developed corrosion resistant fluid heads and valves to prolong service life and reduce downtime.

The Flowplant skid range offers a complete solution for all pipe and vessel hydrotesting tasks. If, however, you need a bespoke system please give us a call. We will work with you to ensure you get exactly the system you need.

We are also able to offer a complete set of complimentary products such as test manifolds and integrated chart recorder systems that will provide a permanent log of results achieved.
