Key Features
- Genuine OEM Material Spec — Manufactured to Multiquip's original material grade and dimensional tolerances, ensuring correct load distribution and surface contact for this pump application.
- Drop-In Replacement — Designed to install in the same position as the original, with no reworking of mating hardware or fasteners required.
- CX400 Fitment Confirmed — Directly compatible with CX400 series Multiquip submersible pumps; part number 020CX400400 identifies this washer precisely within that model family.
- Maintains Fastener Integrity — A correctly sized washer distributes clamping force evenly across mating surfaces, preventing fastener pull-through, surface damage, and loosening under vibration.
- Fluid and Vibration Resistance — Built to withstand the wet operating environment and continuous vibration characteristic of submersible pump service.
A washer serves as a load-distributing interface between a fastener and the surface it clamps against. In a submersible pump like the CX400, washers are critical to maintaining secure, leak-resistant assemblies across housings, impeller stacks, and seal plates that operate under continuous submersion and hydraulic pressure. When a washer is undersized, deformed, or missing, the fastener can work loose over time or damage the mating surface, leading to misalignment, vibration-related failures, or fluid ingress into areas of the pump that must remain sealed.
