Multijet pump unit for Subsea Coatings Removal

Work Starts on Pump Unit for Subsea Coatings Removal

June 2018


Our latest MultiJet high pressure pump unit is in build at our factory in Worcester. This diesel-engine-powered unit will be housed in a sound-reducing, DNV-compliant container with two sets of double access doors.

A Hammelmann reciprocating pump will deliver 120 lpm of seawater at 1200 bar in ambient temperatures up to 50°C. Operation will be through an integral control panel which will display performance data.

The MultiJet unit is a common sight on offshore installations, where its reliability and long time between services is much valued by our customers. This unit is designed and built in conjunction with hydrodemolition equipment specialists Conjet for Norwegian company 4C Solutions as part of a system that will be delivered to a customer in the Middle East and will be supported by our locally based service and spares team.
