Durable Concrete Pump Delivery Cylinder | Precision Honed ST52 Hydraulic Cylinder for Putzmeister & SANY Pumps
Product Introduction
The Concrete Pump Cylinder, also known as the delivery cylinder or main pumping cylinder, is one of the core components of a concrete pump system.
The concrete pump delivery cylinder plays a vital role in the hydraulic delivery system of concrete pumps, transferring the concrete mixture smoothly and continuously. Built from high-grade ST52 or CK45 seamless steel, it undergoes precision honing and hard chrome plating to deliver unmatched wear resistance and hydraulic performance.
