Why Choose the Sulzer XJ 50 Submersible Pump
The XJ 50 is built for rugged dewatering tasks in construction , mining , tunneling , and stormwater applications:
Designed for pumping water and dirty water with light abrasives in environments where durability is essential.
AquaTronic control (optional or built‑in) ensures optimal impeller rotation regardless of phase connection and provides built‑in protection against overload , phase loss , motor overheating , and dry‑run. It also enables anti‑clog backspin and automatic restart.
Plug‑and‑pump setup allows installation without external control panels; diagnostics available directly from the pump without disassembly.
Modular design promotes easy serviceability—external inspection ports , wear-ring adjustment , and USB interface for condition monitoring.

Features & Options
AquaTronic (AT) versions integrate electronics for phase correction , automatic start/stop , thermal and overload safety , anti‑clog operation , and status logs.
Level‑sensor combinations (AquaPlug) enable automatic stop/start by water level with status indicators and diagnostic alerts.
Accessory options: various discharge couplings (3″, 4″, 6″ BSP/NPT/Storz), flotation rings , zinc anode belts for corrosion protection.
Wear-resistant materials: white cast‑iron impeller and wear ring , nitrile rubber coating , dual mechanical seals in an oil bath.
The Sulzer XJ 50 is a high-capacity , robust , and intelligent dewatering pump suitable for demanding site conditions. It delivers significantly higher flow and head than the XJ 40 while maintaining rugged construction , modular design , and advanced electronic protection. Ideal for automated , continuous , or intermittent operations in confined or abrasive environments.
