The Multiquip 1601350350 Check Valve is a genuine OEM component designed for QPT405SLT centrifugal pumps and MQ62TDD and MQ62TK trash pumps. Sourced directly from Multiquip, this check valve meets the same specifications as the original part installed at the factory, ensuring a direct, hassle-free installation. Whether you are servicing a centrifugal dewatering pump or a heavy-duty trash pump, part number 1601350350 is the correct OEM replacement to restore proper pump operation. DHS Equipment stocks this part to keep your Multiquip pump fleet running at full capacity.
Key Features
- Genuine OEM One-Way Flow Control: — Built to the exact sealing and cracking-pressure specifications of the original valve, ensuring consistent one-directional flow without bypass or backflow leakage.
- Direct-Swap Installation: — Matches the original port size, thread pattern, and valve geometry of the 1601350350, dropping into place without rework or adaptation.
- Broad Pump Fitment: — Confirmed for QPT405SLT centrifugal pumps and MQ62TDD and MQ62TK trash pumps, covering both dewatering and solids-handling pump applications.
- Protects Pump Prime and Pressure: — A functioning check valve holds prime between pump cycles and prevents discharge water from flowing back through the pump, protecting the impeller and maintaining output pressure.
- Fluid-System Safety Compliance: — On pump systems handling wastewater, slurry, or site runoff, a correctly rated check valve prevents uncontrolled backflow that can contaminate water sources or damage downstream equipment.
A check valve is a one-way flow control device that allows fluid to pass in only one direction through the pump system. It maintains prime by preventing water from draining back out of the suction line when the pump is idle, and it stops pressurized discharge water from reversing through the pump casing when the unit shuts down. When a check valve fails — through cracking, seat wear, or debris damage — the pump loses prime rapidly, output pressure drops, and the impeller can be subjected to reverse-flow stress that accelerates wear across the entire pump assembly.
