Housing Cover Sealing Function

The O-ring seals the joint between the applicable pump housing components. When installed correctly, it helps prevent liquid leakage while preserving the original wet-end sealing arrangement.

Viton/FKM Material

Viton is a fluoroelastomer used in selected chemical-service sealing applications. The correct seal material must be selected according to the process liquid, concentration, temperature and operating environment.

Compatible March Pump Applications

Manufacturer and distributor documentation identifies 0130-0033-1000 for compatible AC-3C-MD, BC-3C-MD and LC-3C-MD pump configurations. Other Series 3 variants may require different O-ring dimensions or materials.

Maintenance and Replacement

Inspect the original O-ring whenever the pump cover is removed. Replace seals showing cracking, cuts, swelling, flattening or hardening. Clean the sealing groove and housing surfaces before installing the replacement.

Viton vs. Buna-N Replacement

The March 0130-0033-1000 Viton seal has the same nominal dimensions as the Buna-N part 0130-0011-1000, but the elastomer materials are different. Material selection must be based on the original equipment requirement and chemical compatibility.

Selection Guidance

Confirm the complete pump model, sealing location and required elastomer before ordering. Choose March 0130-0033-1000 when the application specifies the OEM Viton/FKM cover O-ring.
