The Multiquip EM25573 Cylinder Oil 7D2 ST30 60 is a genuine OEM lubricant component designed for the ST30 swing tube concrete pump series. As a factory-sourced part, EM25573 meets Multiquip's original material and formulation standards, ensuring compatibility with the demanding hydraulic and mechanical environment inside ST30 concrete pumps. This cylinder oil is a direct OEM replacement, giving you confidence that the correct specification is being fulfilled every time you service your machine.
Key Features
- OEM-Specified Lubricant Grade — Formulated to the exact viscosity and additive profile required for cylinder lubrication in Multiquip swing tube concrete pumps, preventing metal-to-metal wear under high-cycle pumping loads.
- Direct OEM Replacement — Sourced directly from Multiquip as a genuine OEM part, this part installs without modification and meets the original service specification for the ST30 platform.
- ST30 Series Fitment — Confirmed compatible with the Multiquip ST30 swing tube concrete pump, making it straightforward to order the correct product for your machine.
- Protects Cylinder Integrity — Proper cylinder lubrication maintains smooth piston travel and sealing performance; running with degraded or incorrect oil accelerates cylinder bore wear and shortens seal life.
- Supports Consistent Output Pressure — A correctly lubricated cylinder sustains the pressure consistency your pump needs to move concrete efficiently through the line without surge or pressure drop.
Cylinder oil in a concrete pump serves as the protective film between the piston and cylinder bore, reducing friction and heat during the high-pressure, repetitive strokes that push concrete through the delivery line. Without adequate lubrication at the correct specification, cylinder walls and piston seals wear prematurely, leading to pressure loss, increased leakage, and ultimately pump failure. Using the manufacturer-specified oil, such as Multiquip EM25573, ensures the cylinder assembly operates within its designed parameters and delivers the service life the machine was built for.
