The Multiquip EM80423A Main Cylinder is a genuine OEM component designed for LS300, LS300G, and LS300GK hydraulic-driven concrete pumps. Sourced directly from Multiquip, this cylinder meets the exact dimensional and material standards of the original part, ensuring a correct installation without guesswork. It is a direct-fit replacement for the LS300 series, confirming compatibility with each of the listed model codes.
Key Features
- Genuine OEM Construction — Manufactured to the same dimensional tolerances and material specifications as the original cylinder, maintaining consistent stroke volume and pumping pressure output.
- Direct-Fit Replacement — Engineered to align with the hydraulic circuit and mounting points of the LS300, LS300G, and LS300GK, allowing installation without modification to porting or fittings.
- LS300 Series Compatibility — Verified fitment across the LS300, LS300G, and LS300GK hydraulic concrete pump models.
- Sustained Pumping Performance — A correctly functioning main cylinder maintains consistent concrete displacement per stroke; a worn or failing cylinder causes output loss, pressure irregularities, and unplanned stoppages mid-pour.
- Pressure System Integrity — As a hydraulic pressure-bearing component, using a correctly rated OEM cylinder is critical to safe and stable operation of the pump's drive circuit.
The main cylinder is the core reciprocating component in a hydraulic concrete pump's pumping circuit. It receives hydraulic pressure and converts it into the mechanical stroke that pushes concrete through the delivery line, working in a timed sequence with the swing tube or valve system to maintain continuous flow. When the main cylinder wears, develops scoring, or loses sealing integrity, the pump will experience reduced output pressure, inconsistent concrete delivery, and potential hydraulic fluid contamination — all of which can bring a pour to a halt and lead to more extensive repairs if left unaddressed.
