Function in Pump Assembly

The flat washer spreads fastening pressure across the contact surface. This helps maintain the intended assembly arrangement and reduces localized loading beneath the fastener head.

Stainless Steel Construction

March specifies stainless steel for the component, providing corrosion resistance for the manufacturer-approved hardware location.

Compatible Pump Families

Official parts documentation lists the washer in compatible TE-6K-MD, TE-7P-MD and TE-7K-MD pump-less-motor configurations. It also appears in March Series 830 assemblies.

Maintenance and Replacement

Inspect washers for bending, corrosion, cracking and abnormal wear during pump service. Replace unsuitable hardware before reassembly and follow the correct fastener tightening instructions.

Confirm the pump model, original washer location and exact March part number. The 0155-0021-1000 is an assembly washer rather than a hydraulic or sealing component.
