Multiquip EM14334 Compensator Spring - OEM Replacement Part for C30HD Concrete Pumps

The compensator spring installs on the compensator piston rod and deflects with each piston stroke to produce an uninterrupted, smooth flow of material during concrete pumping operations. This spring cushion works in conjunction with the cam profile to eliminate shock and stress between components under average pumping conditions, preventing premature wear and ensuring consistent performance.

Critical to pump operation, this spring maintains proper pressure balance between the pumping and compensator cylinders. When replacing the compensator spring, maintain the backing plate dimension of 3 inches as specified in Multiquip technical documentation to produce proper pre-loading for smooth performance. Failure to maintain correct spring preload can result in rough operation, material flow inconsistencies, and increased stress on cam rollers and rocker arm assemblies.

Compatible with the following Multiquip concrete pump models:

• C30HDGA
• C30HDN
• C30HDNI
• C30HDZ
