Multiquip 301010630 Spring Cylinder 80A DNS - OEM Replacement Part

This spring cylinder is a critical hydraulic component in the concrete pump's reciprocating piston system, providing the necessary force and return tension to maintain consistent pumping action under the LS450's 1,100 psi piston face pressure. The 80A durometer rating ensures the spring maintains its compression characteristics even during extended pumping operations up to 45 cubic yards per hour. This DNS (Do Not Substitute) specification indicates precise engineering tolerances required for proper cylinder operation and hydraulic system integration.

In concrete pump applications, the spring cylinder works in conjunction with the reciprocating piston mechanism to deliver continuous material flow through 3-5 inch diameter hoses. Failure symptoms include irregular pumping rhythm, reduced output pressure, or hydraulic fluid contamination in the cylinder lubrication system. Regular inspection of spring cylinders should be performed during the 50-gallon hydraulic fluid service intervals to prevent catastrophic pump failure on jobsites.

Compatible with the following Multiquip concrete pump models:

• LS450
