Modern fuel oil systems incorporate flow and pressure control, this enables a low pressure ‘stand by’ status to be adopted when the trigger nozzle is closed. This feature allows the easy manipulation of the delivery hose which is in constant use when the system is in operation. This requires continual actuating of the relief valve which, overtime, can rupture the membrane of the original equipment valve supplied with some radial vane cargo pumps. This damage to the membrane cause’s leaks before complete failure.
At MechTronic we have developed our own robust version of the relief valve which incorporates a simple O-ring seal design. This feature ensures trouble free running of the system and can be retrofitted to the Blackmer TXH3 and TXD2.5 pumps.
