The Multiquip EM403000 is a genuine OEM Material Cylinder 3.75" Dia designed for MG30 series fireproofing pumps and mixers. This cylinder is a direct-fit replacement for MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 equipment, ensuring proper installation without improvisation or adaptation. Sourced directly through Multiquip's authorized parts network, the part meets the original engineering specifications required to keep your pump operating at rated output. DHS Equipment stocks this part to support contractors who depend on consistent material throughput on demanding fireproofing and masonry applications.
Key Features
- OEM-Grade Bore Integrity — Manufactured to the original 3.75" diameter specification, ensuring consistent compression and material displacement with every stroke.
- Drop-In Installation — Engineered to match the original cylinder housing dimensions on MG30 series units, allowing straightforward removal and replacement in the field.
- Broad MG30 Series Fitment — Compatible with MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 fireproofing pumps and mixers.
- Sustained Pumping Pressure — A correctly sized cylinder maintains the seal and stroke volume needed to deliver steady, uninterrupted material flow; a worn cylinder causes pressure loss and uneven output.
- Genuine Multiquip OEM Part — Carries the full backing of Multiquip's OEM parts program, giving you confidence in long-term dimensional stability under high-cycle pumping conditions.
The material cylinder is the core pumping component inside an MG30 series fireproofing pump. As the piston cycles through the cylinder bore, it draws material in on the intake stroke and forces it through the discharge line on the compression stroke. The 3.75" bore diameter directly determines how much material is moved per cycle, which controls both output volume and line pressure. When the cylinder wall wears or becomes damaged, the piston can no longer maintain an effective seal, leading to pressure drop, inconsistent flow, and accelerated wear on surrounding pump components.
