Hughes Pumps Delivers Unique High Pressure Twin Pump Solution

April 22, 2012

   Hughes Pumps has recently supplied a leading multi-national offshore contractor with a unique high pressure twin pump system for the flushing and pressure testing of subsea pipelines during pre-commissioning operations.

   The system, comprising of a twin pumpset mounted in a compact, fully enclosed, certified offshore crashframe, was specifically configured to enable one pump to operate alone with the second on standby for critical operations or for both pumps to operate simultaneously; either individually or together.

   Each HPS2200 pump produces 170 liters per minute at 300 bar (45 gallons per minute at 4,350 psi) and was built with 316 stainless steel pumpheads, suitable for use with seawater. The unique integral gearbox and SAE engine adaptor pump design make for an extremely compact installation, reducing the machine’s footprint to a minimum – a pre-requisite for any offshore installation where space is at a premium.

   Designed for use in semi-hazardous areas, the unit utilises “Rig-Safe” diesel engines comprising an air start system, spark arresting exhaust silencer, Chalwyn air intake shutdown valve and mechanical shutdown system for both engines and pumps, negating the need for any electronics.

   Housed in a DNV (Det Norsk Veritas) certified offshore crashframe, the unit is suitable for use offshore in both freezing conditions and ambient temperatures up to 50 degrees Celsius (122 degrees Fahrenheit).
