Babcock utilised Crests ‘No obsolete parts’ policy after 13 years of continuous operation, improved efficiency and saved money.


Babcock Marine is the UK’s leading naval support company providing servicing, infrastructure management, operations management and strategic planning to the Ministry of Defence and variou other ship builders, marinas and energy companies including BP and Shell.

Babcock were working longside the Ministry of Defence to start on a raft of renovation works to improve cost efficiency and streamline operationg at the HM Naval Base in Clyde.

Part of the operation improvmenets incdlued to the efluent treatments parts to the vessel docks. Effluent water would be unloaded into deep sumps and then process into a regeneration tank.

We originally supplied the SVB in 1990 for the construction of that part of the site. These pumps were supplied to provide an efficient pump in a stainless steel construction, with an extended column length for the depth of the pump.

Babcock utilised our ‘No obsolete Parts’ policy and after 13 years of continuous operation, reordered the 2 SVB’s with upgraded efficiency and motor requirements.

These upgraded pumps needed a further extension of 1 meter on the column length, bringing the total to 4.3 meters depth. Stiffening bars were included to give maximum strength.

These upgraded SVB pumps with their improved efficiency, meant to the motor size could be reduced from 4.4kW down to 2.2kW giving a saving of £980 per pump, per annum, from the previous pumps.

By Choosing Crest Pumps as the supplier of a customer made UK manufactured vertical pump, Babcock and the Ministry of Defence ensured continued safe and reliable pumping over a long period of time. While the original pumps lasted over 13 years with trouble free operation, at least the same is expected with the updated models.
