The customer contacted us requiring quantity 5 x sea water cooling pumps on a quick lead time.


We selected 5 of our AN 40/250 long coupled centrifugal pumps in bronze. The long coupled design separates the pump from the motor allowing easier maintenance and also reducing the risk of any fluid entering the motor in the event of a mechanical seal failure. The pumps are fitted with 4 pole motors running at 1750RPM, the slower motor speed reduces the wear on the pump in the long term making them perfect for 24/7 applications such as this. All 5 sea water cooling pumps were manufactured and delivered to the customer in less than 5 weeks.
