05.02 What accessories are needed for fuel transfer pumps?

• Isolation Valves: Typically manual ball valves to isolate the pump for service.
• Gauges: Typically liquid filled gauges 2.5” to 4” dials both vacuum for pump inlet and pressure for pump outlet.
• Strainers: Inlet strainers to prevent debris in piping system from damaging pump.
• Check Valves: at pump discharge to prevent backflow through pump, or on pump inlet to maintain prime on suction pumps.
• Flex Connectors – Vibration Isolators: to isolate the pump vibration from the piping system.
• Pressure Relief / Regulating Valves: To allow flow through pump when downstream valves are closed and prevent overheating of pump body, and for thermal expansion relief in piping.
