The Multiquip 511307 Check Valve Pin is a genuine OEM component designed for MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, and MQ600TD80-TLRP trash pumps. As a direct OEM replacement, part 511307 is manufactured to the same specifications as the original, ensuring a proper fit within the check valve assembly without modification. Sourced directly through authorized Multiquip supply channels, this pin delivers the exact fitment your pump requires to maintain consistent flow control and priming performance.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring correct dimensional tolerancing for secure seating within the check valve assembly.
- Drop-In Compatibility — Designed to install directly into the check valve on MQ600H, MQ600HTB, MQ600HTP, MQ600TD80-TLRB, and MQ600TD80-TLRP trash pumps.
- Maintains Valve Integrity — A properly fitted check valve pin holds the valve in correct alignment, allowing the pump to build prime and sustain one-directional flow under demanding trash pump conditions.
- Prevents Priming Loss — A worn or missing check valve pin allows the valve to shift or fail to seat, causing the pump to lose prime, reduce output pressure, or fail to self-prime altogether.
- Verified Part Number — Order with confidence using Multiquip part number 511307, matched to the MQ600 series trash pump family for accurate fitment.
The check valve pin is a small but critical component within a trash pump's check valve assembly. Its role is to anchor and guide the valve disc or flap so that fluid can only flow in one direction — allowing the pump to self-prime and maintain pressure during operation. When this pin becomes worn, bent, or lost, the check valve loses its ability to seat correctly, which typically causes the pump to fail to prime, surge erratically, or deliver reduced flow. Replacing the 511307 Check Valve Pin restores proper valve function and gets the pump back to reliable operation.
