March 0809-0012-1000 Stainless Steel Rear Housing

The March 0809-0012-1000 is an original equipment stainless steel rear housing for compatible March Series 809 magnetic drive centrifugal pumps. March identifies the component in its 809-SS pump parts breakdown, while distributor listings identify the replacement housing as 304 stainless steel.

The rear housing forms part of the pump wet end and works with the front housing, impeller, shaft and sealing components to maintain the intended liquid-handling chamber.

Rear Housing Function

The housing contributes to the fluid-containing assembly of the magnetic drive pump. Its geometry is important for correct positioning of the internal components and maintaining the original pump construction.

Replacing a damaged housing with the specified March component can help address physical damage or deterioration without requiring replacement of the entire pump.

Stainless Steel Construction

The stainless steel housing is associated with selected Series 809 pump configurations. The exact alloy and chemical suitability should be checked against the original pump documentation and service conditions.

Compatible March Pumps

The official March 809-SS parts breakdown includes part 0809-0012-1000. Other Series 809 versions may use different housing materials or configurations, so the exact model must be verified before ordering.

Maintenance and Inspection

Inspect the original rear housing for corrosion, cracks, damaged sealing surfaces and signs of contact with the rotating assembly. Check the O-ring, impeller and shaft during pump disassembly.

Choosing the Correct OEM Housing

Choose March 0809-0012-1000 when the pump requires the corresponding stainless steel rear housing. This is an individual wet-end replacement component, not a complete pump or replacement kit.
