Multiquip 511307 Pin Check Valve - OEM Replacement Part

The pin check valve maintains prime in your Multiquip trash pump by keeping water in the pump casing between operations, eliminating the need for repriming and ensuring immediate startup when you need it. This internal check valve component uses neoprene rubber reinforced with internal steel construction to withstand the demanding conditions of high-volume trash pumping applications.

Designed specifically for the MQ600H series trash pump, this check valve works in conjunction with the pump's 6-inch NPT suction and discharge ports to maintain system pressure. The MQ600H operates at up to 64.9 PSI with a maximum head of 150 feet and pumping capacity up to 1600 gallons per minute. The check valve's steel-reinforced neoprene construction provides reliable sealing even with maximum fluid temperatures up to 104°F.

Check valve failure symptoms include loss of prime, extended startup times, or inability to maintain suction. Regular inspection of the check valve during routine maintenance helps prevent unexpected downtime on jobsites.
