Multiquip 37104 Hydrogear Pump

The Multiquip 37104 Hydrogear Pump is a genuine OEM hydraulic pump designed for PS, SP, and CS series pavement saws. This factory-sourced component is built to the original engineering specifications for the full range of Multiquip flat-cut and pavement saw platforms, including PS403016, PS403020, PS403026, PS403030, PS706016, PS706020, PS706026, PS706030, PS706036, SP403016, SP403020, SP403026, SP403030, SP706016, SP706020, SP706026, SP706030, SP706036, CS403016, CS403020, CS403026, CS403030, CS706016, CS706020, CS706026, CS706030, and CS706036. As a genuine OEM part, the part delivers the hydraulic output and dimensional fit the machine was engineered around. Sourced directly through DHS Equipment, this pump is the correct replacement when your existing unit shows pressure loss, erratic blade drive, or hydraulic failure.

Key Features

• Genuine OEM Hydraulic Output: — Manufactured to the original flow and pressure ratings the PS, SP, and CS saw platforms were designed around — not a close approximation.
• Drop-In Hydraulic Fit: — Matches the original port configuration, shaft dimensions, and mounting pattern for a clean swap with no rework to hydraulic lines or mounting hardware.
• Broad Saw Compatibility: — Confirmed fitment across the PS, SP, and CS pavement saw series, covering both 30 HP Deutz diesel configurations and a wide range of blade-size variants.
• Restores Full Blade Drive Performance: — A failed or worn hydrostatic pump causes loss of blade speed control and inconsistent cutting depth; replacing it with part this part restores consistent, controlled hydraulic drive to the blade system.
• Critical Hydraulic System Integrity: — The pump is the heart of the hydraulic circuit on these saws; using a correctly rated OEM unit ensures system pressure stays within the safe operating range for the blade, drive, and feed controls.

The Hydrogear Pump is the hydraulic power source that drives the blade rotation and feed systems on Multiquip pavement saws. It converts engine mechanical power into pressurized hydraulic flow, which the saw's control circuit uses to regulate blade speed and cutting force. When the pump wears or fails, operators typically see sluggish blade engagement, erratic speed control, or a complete loss of hydraulic drive — all of which bring cutting operations to a stop and can place unsafe loads on the engine and hydraulic circuit downstream.
