March 0125-0061-1000 Shaft 0125-0061-1000

The March 0125-0061-1000 Ceramic Shaft is an OEM wet-end component used in multiple compatible March Series 2 magnetic drive pump configurations. The stationary shaft supports and aligns the rotating impeller assembly, making its condition important to smooth wet-end operation.

Series 2 Pump Compatibility

March identifies 0125-0061-1000 as the standard ceramic shaft in pump configurations such as the AC-2AP-MD and AC-2CP-MD, and the part also appears across additional compatible Series 2 assemblies. This makes the part useful for maintenance of several related March pump models, but compatibility should always be verified against the exact pump parts breakdown.

Ceramic Wet End Construction

Ceramic is used by March for wear-related wet-end components in many magnetic drive pump designs. In the AC-2AP-MD, the ceramic shaft works with a ceramic thrust washer and polypropylene impeller containing a ceramic magnet. This arrangement supports the rotating impeller without requiring a conventional motor shaft to pass through the pump housing.

Replacement During Pump Maintenance

Inspect the shaft whenever the wet end is disassembled. Chipping, scoring, abnormal wear or damage can affect the way the impeller rotates and may indicate that related components should also be examined. The impeller bore and thrust washer should be inspected before reassembling the pump with a replacement shaft.

Important Material Variant

Do not assume every Series 2 pump uses this ceramic shaft as standard. For example, March currently lists a stainless steel shaft as standard in the 2CP-MD, with 0125-0061-1000 available as a ceramic option. Exact model configuration therefore matters when selecting a replacement.

Selection Guidance

Match the manufacturer part number, pump model and existing shaft material before ordering. If a material change is being considered rather than a direct like-for-like replacement, confirm that the resulting wet-end configuration is appropriate for the liquid and operating conditions.
