The Wacker Neuson Gear Motor is a genuine OEM component designed for the E1250 and HSH380 series hydronic surface heaters. Sourced directly from Wacker Neuson, this gear motor meets the exact specifications required for correct operation across the E1250S, E1250B, E1250P, HSH380S, and HSH380B heater models — covering LP/NG, diesel, and generator-equipped configurations. As a genuine OEM part, it provides a direct, like-for-like replacement with no guesswork on compatibility. Whether you're servicing a Standard, Basic, or Premium variant, part number is the correct replacement gear motor for this family of hydronic heaters.
Key Features
- Genuine OEM Torque and Speed Spec: — Manufactured to Wacker Neuson's exact output specifications, ensuring the gear motor drives fluid circulation at the correct rate for consistent heat delivery.
- Direct Drop-In Replacement: — Engineered to mount and connect exactly as the original unit, matching bolt pattern, shaft dimensions, and electrical interface across the E1250 and HSH380 series.
- Broad Series Coverage: — Fits E1250S, E1250B, and E1250P models in LP/NG and diesel configurations, plus HSH380S and HSH380B in both generator-equipped and non-generator variants.
- Sustained Circulation Performance: — A functioning gear motor keeps heated fluid moving through the system continuously; a worn or failed unit will cause uneven surface heating or complete loss of heat output.
- Verified OEM Part Number: — Part number 5200011250 is the Wacker Neuson-assigned reference for this component, giving you confidence you're ordering the correct part before it ships.
The gear motor in a hydronic surface heater is responsible for driving the circulation pump that moves heated fluid through the hose network and heating blankets or mats laid on the concrete or ground surface. Without consistent motor-driven flow, heat cannot be distributed evenly across the curing area, leading to inconsistent concrete curing temperatures or system shutdown. A worn or seized gear motor will stop fluid movement entirely, making prompt replacement critical to keeping hydronic heating operations on schedule during cold-weather pours.
