Multiquip EM18800HD Pumping Cylinder

The Multiquip EM18800HD Pumping Cylinder is a genuine OEM component designed for the C30 series concrete pumps, including the C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, C30HDGA, C30HDZ, and C30HDN. As a direct OEM replacement, the EM18800HD is manufactured to the exact tolerances required to maintain consistent pumping pressure and output in demanding concrete placement applications. Sourced from Multiquip, this cylinder meets the original engineering specifications for Mayco C30 cycloidal-driven pump models. If you are servicing a C30-series unit and need a part you can trust to perform from the first pour, the EM18800HD is the correct replacement.

Key Features

• OEM-Grade Bore Tolerancing — Manufactured to original dimensional specifications to maintain correct hydraulic sealing and consistent concrete displacement per stroke.
• Direct Drop-In Replacement — Engineered to swap directly into the pumping assembly of C30 series units without modification to surrounding components.
• Broad C30 Series Coverage — Fits C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDG, C30HDGA, C30HDZ, and C30HDN Mayco concrete pump models.
• Sustained Output Pressure — A correctly sized pumping cylinder maintains line pressure and volume, preventing short-stroking or material starvation at the discharge end.
• Wear-Critical Component — The pumping cylinder is one of the highest-wear surfaces in the system; replacing it at the right service interval prevents accelerated damage to seals, pistons, and the pump housing.
• Genuine Multiquip OEM Part — Backed by Multiquip's parts program and sold by DHS Equipment, an authorized Multiquip parts distributor.

The pumping cylinder is the primary hydraulic bore through which the concrete piston travels on each stroke, generating the displacement pressure that moves mixed concrete through the delivery line. It works in direct contact with the piston and its seals, so surface finish and dimensional accuracy are critical — even minor wear or out-of-round conditions cause pressure loss, uneven flow, and accelerated seal failure. When a pumping cylinder is worn or damaged, the pump loses output consistency, begins to short-stroke, and can ultimately fail to move material through the line entirely, causing costly job delays and potential blockages.
