Our BOP test systems and pumps are designed and packaged in a variety of formats to suit the specific location, operating, and application requirements. All design and manufacturing takes place at our factory in Worcester, UK.

The high pressure pump has a space-saving, vertical design. Discharge pressures of up to 3,000 bar, variable stroke options, long time between services, and superb reliability make our pumps ideal for blowout preventer testing.

The optional self-contained mixing tank can prepare the test water to suit the prevailing environmental conditions. A stand-alone accumulator skid can also be supplied which allows the pressure to build to pre-set levels to provide adequate flow rates of test water into the blowout preventer. Our speciality is BOP test units requiring higher test flowrates & pressures due to our use of the triplex plunger pump within our design. Control system packages are tailored to suit your requirements, from basic functionality to complete control system philosophy. Options include on-board control, remote operation, system monitoring, fault finding, and data logging.

We offer full after-sales support through our team of offshore trained engineers. Call us +44 1905 751790 to find out how we can assist you with your BOP test pump requirements or email our sales engineers: sales@calder.co.uk
