The Multiquip 43438 Electric Drive Coolant Pump is a genuine OEM component designed for the PRX series hybrid ride-on power float. Sourced directly from Multiquip, this part meets the exact specifications required by the PRX hybrid trowel platform, which relies on a precisely controlled electric-driven cooling circuit to protect its powertrain. Confirm your model number against the PRX series before ordering to ensure correct application.
Key Features
- Genuine OEM Cooling Performance — Engineered to deliver the correct flow rate and pressure for the PRX hybrid system's thermal management demands, not a generic pump adapted to fit.
- Direct-Fit Electric Drive Design — Matches the original electrical connector, mounting flange, and flow orientation for a straightforward swap with no improvised adapters.
- Built for PRX Hybrid Trowels — Verified fitment for the PRX series hybrid ride-on power float, covering the combined internal combustion and electric blade-drive architecture.
- Protects Critical Hybrid Components — Consistent coolant circulation prevents heat buildup in the electric drive system; a failing pump risks overheating and unplanned machine downtime.
- Exact OEM Part Number — Part number 43438 matches Multiquip's own service documentation, giving technicians and operators confidence they are installing the correct component.
The electric drive coolant pump circulates coolant through the PRX hybrid trowel's powertrain to regulate operating temperature across both the combustion engine and the electric motor drive system. Unlike a passive cooling arrangement, the electrically driven pump maintains consistent flow independent of engine speed, which is especially important during low-RPM finishing passes when heat still builds in the drivetrain. When this pump weakens or fails, coolant flow drops, temperatures rise, and the hybrid drive system becomes vulnerable to heat-related damage that can take the machine out of service entirely.
