March 0130-0021-1000 Polypropylene Cover 3/4 Inch FPT Inlet 0130-0021-1000

The March 0130-0021-1000 Pump Cover is an OEM polypropylene front housing used on multiple compatible March Series 3 magnetic drive pumps. March identifies this cover with a 3/4-inch FPT female inlet, where it forms the suction side of the pump wet end.

The same part is currently shown in AC-3CP-MD, BC-3CP-MD, LC-3CP-MD and related Series 3 assemblies, making it an important shared service component across several March magnetic drive pump configurations.

Key Features

• Genuine March OEM Series 3 pump cover
• Part number 0130-0021-1000
• Polypropylene construction
• 3/4-inch FPT inlet
• Used in compatible AC-3CP-MD, BC-3CP-MD and LC-3CP-MD pumps
• Forms the front section of the pump wet end
• Compatible with the applicable Series 3 O-ring and thrust washer arrangement

Wet End Function

The front cover directs incoming fluid into the impeller chamber and works with the rear housing and O-ring to contain the process liquid. Correct internal geometry and sealing surfaces are important for reliable wet-end operation.

Polypropylene Material

Polypropylene is used as the standard cover material in many March Series 3 chemical pump configurations. It provides a practical balance of corrosion resistance and mechanical performance for compatible fluids.

Threaded 3/4-Inch Inlet

The 3/4-inch FPT inlet is an important identification feature because March also manufactures related Series 3AP configurations using smooth 3/4-inch OD inlet connections. Confirm the connection style before selecting a replacement.

Replacement Guidance

Replace the cover if it is cracked, distorted, damaged at the threaded connection or chemically degraded. Inspect the cover O-ring, thrust washer and nearby impeller components during the same service procedure.

Selection Guidance

Verify the exact pump model, inlet type and original March part number. The 0130-0021-1000 is the correct OEM cover where the compatible Series 3 wet end requires the polypropylene 3/4-inch FPT inlet configuration.
