North Ridge Pumps has supplied on-board pumps with marine type approval for a ship\u2019s hot water boosting and air conditioning cooling system.
One of its customer\u2019s ships was undergoing a refit during dry dock when it was discovered the pumps were damaged beyond economical repair.
There was limited space in the engine room so North Ridge Pumps selected two of its VM 80\/20A vertical inline centrifugal pumps\u00a0with cast bronze casings and impellers for corrosion resistance. Marine type approval is mandatory for equipment onboard many vessels and the pumps are Lloyds type approved. The flange to flange and inlet\/outlet connections are the same as the existing unit, making installation straightforward.\u00a0
Two of the company\u2019s MO 19\/20 horizontal side channel self-priming pumps\u00a0were also selected for the hot water boosting system. As they are pumping fresh water at 70\u00b0C, a cast iron casing with bronze impeller is sufficient. A low flow rate of 3m\u00b3\/hr at 4.5 bar was required and because of the pumps\u2019 design, they can produce low flow rates at medium to high pressures which is difficult for centrifugal pumps to achieve.<\/p>\n","protected":false},"excerpt":{"rendered":"
