The Multiquip 2131 Discharge Plate is a genuine OEM component designed for Whiteman ride-on mechanical trowels — including the HHN34TVD, HTN28K, and HTN27K — as well as MQD3H and MQD2H diaphragm pumps. As a direct Multiquip OEM part, the 2131 is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation without guesswork. Whether you are servicing a finish trowel on a concrete flatwork crew or maintaining a diaphragm pump on a dewatering application, this discharge plate keeps your equipment running as intended. Verify your model code against the fitment list and order with confidence from DHS Equipment.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, so the plate seats and seals exactly as the factory-built unit did.
- Direct Drop-In Replacement — Engineered to match the original mounting pattern and port geometry, so installation follows the same procedure as the part being replaced.
- Broad Fitment Coverage — Compatible with HHN34TVD, HTN28K, and HTN27K Whiteman ride-on mechanical trowels, plus MQD3H and MQD2H diaphragm pumps under a single part number.
- Maintains Flow and Pressure Integrity — A correctly seated discharge plate controls the direction and pressure of fluid or air discharge; a worn or cracked plate leads to backflow, pressure loss, and accelerated wear on surrounding components.
- Verified Multiquip Part Number — Sourced directly through the Multiquip OEM supply chain and listed under part number 2131, so you can cross-reference with your service manual before ordering.
A discharge plate controls the one-way flow path through a pump or valve body, directing output toward the discharge port while preventing backflow into the system. In a diaphragm pump, it works in tandem with the inlet plate to create the pressure differential that moves fluid with each stroke cycle. When the discharge plate cracks, warps, or loses its sealing surface, the pump loses prime, output volume drops, and the diaphragm and valve assembly take on additional stress — making timely replacement critical to keeping the pump operating at rated capacity.
