Why Choose the Sulzer XJ 900 Submersible Pump
Designed for the most demanding mining , tunneling , and heavy-duty construction dewatering applications.
Converts easily between high-head (HD) and high-flow (ND) configurations by swapping impellers and diffusers—minimizing inventory needs.
Built on a robust white cast‑iron structure with strong cooling properties , allowing performance even down to the strainer level.
Equipped with a high-efficiency IE3 motor and low‑friction bearings for reduced energy use and operating costs.
Advanced motor protection features: thermal sensors , seal leakage sensors , optional bearing temp monitoring , all triggering automatic shutdown to prevent damage.
The Sulzer XJ 900 is a top-tier pump in the XJ series, delivering exceptionally high flow and head performance with the operational flexibility to convert between high-flow and high-head hydraulics. It features rugged construction , intelligent motor protection , and a design built for tough , heavy-duty dewatering environments.
