Multiquip EM14904 Piston Cup Kit C-30HD - OEM Replacement Part

The piston cup kit is a critical wear component in the concrete pumping system, providing the essential seal between the piston and cylinder wall that creates the pressure needed to move concrete through the discharge line. This kit includes all necessary cups and seals to restore proper piston sealing and maintain optimal pumping performance in your C-30HD concrete pump.

During operation, piston cups are subjected to constant abrasion from concrete aggregate, leading to gradual wear that reduces pumping efficiency and output pressure. Signs that replacement is needed include decreased pumping performance, increased cycle times, concrete leaking past the pistons, or visible wear on cup surfaces during routine inspection. Regular replacement of piston cups during scheduled maintenance intervals helps prevent costly downtime and ensures consistent concrete flow rates on the jobsite.

This kit is designed specifically for C-30HD series concrete pumps and ensures proper fit and durability when servicing the pump end assembly. The hopper on these units holds 6.0 cubic feet of concrete, and maintaining proper piston cup condition is essential for achieving rated output and preventing material bypass.

Compatible with the following Multiquip concrete pump models:

• C30HDGA
• C30HDN
• C30HDNI
