Multiquip EM98257 Main Pump 100CC Parker P1-100 Series

The Multiquip EM98257 Main Pump 100CC Parker P1-100 Series is a genuine OEM hydraulic pump designed for LS60TD, LS600, and LS600P hydraulic-driven concrete pumps. As a factory-sourced component, EM98257 is built to the same engineering standards as the original unit, ensuring a direct, correct-spec replacement for the hydraulic drive system at the heart of these machines. Sourced directly through Multiquip's OEM supply chain, this Parker P1-100 Series pump is the specified replacement for operators and service technicians maintaining LS-series concrete pumps in demanding production environments.

Key Features

• Genuine OEM Hydraulic Integrity — Factory-sourced Parker P1-100 Series piston pump matched to the original hydraulic output ratings of the LS-series drive system, not a generic substitute.
• Direct-Fit Replacement — Engineered to bolt into the existing hydraulic circuit on LS60TD, LS600, and LS600P concrete pumps using the original mounting configuration and port connections.
• LS-Series Concrete Pump Compatibility — Confirmed fitment for LS60TD, LS600, and LS600P hydraulic-driven concrete pump models.
• Sustained Output Under Load — A properly functioning main pump maintains consistent hydraulic pressure and flow to drive concrete displacement; a worn or failed unit causes output loss, irregular strokes, or complete pump shutdown.
• Hydraulic System Safety — Correct pump displacement and pressure ratings are critical to safe operation of hydraulic concrete pumps; using the specified OEM unit prevents pressure imbalance and protects downstream hydraulic components.

The main hydraulic pump is the power source of a hydraulic-driven concrete pump, converting mechanical energy from the engine into the pressurized hydraulic flow that drives the concrete piston circuit. On LS-series machines, the Parker P1-100 Series axial piston pump delivers the high-pressure output required to push concrete through the delivery line at consistent volume and pressure. When the main pump loses displacement efficiency — through internal wear, seal failure, or cavitation damage — the machine will produce reduced concrete output, erratic cycling, or fail to prime, requiring immediate pump replacement to restore full production capacity.
