The Multiquip 1378100020 is a genuine OEM Back Plate QP-205SM designed specifically for the QP-205SM quick-prime trash pump. Sourced directly from Multiquip, this part meets the original engineering specifications for the QP-205SM, ensuring a proper fit within the pump assembly. DHS Equipment supplies this as an authorized Multiquip OEM replacement, so you can be confident you are receiving the correct component for your machine.
Key Features
- OEM-Grade Pump Housing Integrity — Manufactured to the same material and dimensional standards as the original, maintaining proper sealing surface contact within the QP-205SM pump casing.
- Direct-Fit Replacement — Engineered to bolt directly into the QP-205SM pump housing with no rework or machining required to mating surfaces.
- Confirmed QP-205SM Fitment — Compatible with the Multiquip QP-205SM quick-prime trash pump; use part number 1378100020 to verify application before ordering.
- Sustained Pump Output — A properly seated back plate maintains the tight clearances needed for efficient fluid movement; a worn or damaged plate causes pressure loss and reduced flow performance.
- Genuine OEM Sourcing — Supplied as an authentic Multiquip component, not a generic substitute, so fit and function align with the original pump design.
The back plate is a critical structural component of the pump's wet-end assembly. It forms the rear boundary of the pump volute, working in close tolerance with the impeller to direct fluid flow and maintain pumping pressure. When the back plate wears, becomes scored, or cracks, the pump loses the ability to move water efficiently — resulting in reduced discharge volume, loss of prime, or complete pump failure. Replacing a damaged back plate with a correct OEM part restores proper hydraulic performance and extends the service life of the surrounding pump components.
