The Multiquip EM25711 Engine Diesel Hatz 4M40L is a genuine OEM replacement engine designed for the ST-70 submersible pump. Sourced directly from Multiquip, this is the factory-specified power unit for the ST-70, ensuring correct mechanical integration and output characteristics. Buyers can order with confidence knowing this engine matches the original specification without adaptation or compromise.
Key Features
- Genuine OEM Power Unit — Factory-specified Hatz 4M40L diesel engine with confirmed displacement, output rating, and mounting configuration matched to Multiquip's build standards for the ST-70.
- Direct-Fit Installation — Engine mounts, shaft dimensions, and connection points align directly with the ST-70 pump housing, allowing a straightforward like-for-like swap.
- Confirmed ST-70 Fitment — Verified compatibility with the Multiquip ST-70 submersible pump — use part number EM25711 to confirm accuracy before ordering.
- Sustained Pump Output — A properly functioning Hatz 4M40L maintains consistent drive torque for continuous submersible pumping operations; a worn or failed engine results in loss of flow rate and pump failure under load.
- Hatz Diesel Durability — Hatz multi-cylinder diesel engines are known for high thermal efficiency and robust construction, suited to demanding continuous-duty pump applications in wet or confined environments.
The Hatz 4M40L is a multi-cylinder diesel engine that serves as the primary power source driving the ST-70 submersible pump. It converts fuel combustion into rotational output, which drives the pump impeller to move water or fluid from the source. When this engine degrades or fails, the pump loses the mechanical power needed to maintain flow, making timely replacement essential to keeping operations running.
