March 0320-0004-0300 Polypropylene Impeller

Product Overview

The March 0320-0004-0300 is a polypropylene replacement impeller for compatible March Series 320 magnetic drive centrifugal pumps. The impeller transfers rotational energy to the pumped liquid and is a key component of the internal wet-end assembly.

March identifies this impeller in the manufacturer parts breakdowns for the 320-AP-MD and TE-320AP-MD pump families. It works with the corresponding ceramic shaft, thrust washer, front cover, and rear housing.

Key Features & Benefits

• Polypropylene Construction: Matches the manufacturer-specified impeller material.
• Series 320 Application: Listed for compatible air-cooled and TE configurations.
• Internal Pump Component: Supports the original centrifugal liquid-moving arrangement.
• Individual Replacement: Allows targeted impeller maintenance instead of complete pump replacement.

Applications & Maintenance

This replacement impeller supports approved liquid circulation and transfer applications using compatible Series 320 pumps. Impeller vanes and internal bearing surfaces should be inspected when pump operation becomes abnormal or physical damage is suspected.

During service, examine the ceramic shaft, thrust washer, O-ring, and housing surfaces. Confirm that debris, dry running, or other operating problems have been addressed before returning the pump to service.

Compatibility & Ordering Notes

Identified for compatible March 320-AP-MD and TE-320AP-MD pumps. Confirm the complete pump model and original impeller part number. This is an impeller replacement, not a complete wet end kit.
