The Multiquip 336005001 Suction Plate is a genuine OEM component designed for MQD2HA, MQD3HA, MQD2H, and MQD3H diaphragm pumps. As a direct factory replacement, this part ensures the pump's fluid check and suction valve assembly seats and seals exactly as intended. Sourced directly through Multiquip's OEM supply chain, the 336005001 meets the same material and dimensional standards as the original part installed at the factory. If you're servicing any of the MQD2H or MQD3H series diaphragm pumps, this is the correct replacement suction plate to restore full pumping performance.
Key Features
- Genuine OEM Material Integrity — Manufactured to Multiquip's original material specifications, ensuring the plate maintains correct flatness and surface finish for proper valve seating in the pump body.
- Drop-In Replacement — Matches the original bolt pattern, port alignment, and thickness of the factory suction plate, allowing straightforward installation during pump servicing.
- Confirmed Fitment for MQD2H and MQD3H Series — Verified for use on MQD2HA, MQD3HA, MQD2H, and MQD3H diaphragm pump models.
- Restores Full Suction Efficiency — A worn or warped suction plate causes pressure loss, reduced flow rate, and inconsistent priming; replacing it with this OEM part restores the pump's rated suction and discharge performance.
- Fluid Compatibility Assurance — Constructed from materials suited to the fluid handling demands of diaphragm pump operation, including the abrasive or chemically active media these pumps commonly handle on the jobsite.
The suction plate is a critical internal component in a diaphragm pump's check valve system. It forms a precision mating surface against which the suction check valve seats during the pressure stroke, creating the seal that directs fluid flow in one direction through the pump. When the suction plate becomes worn, scored, or warped, the valve can no longer seal cleanly — resulting in backflow, loss of prime, reduced output pressure, and inefficient pumping cycles. Replacing a damaged suction plate with a correct OEM part like the Multiquip 336005001 is one of the most direct ways to return a diaphragm pump to its full rated performance.
