Why Choose the Sulzer XJS 50 Sludge Pump?
Built to handle heavy sludge and solids-laden water, with a clog-resistant vortex impeller and volute
AquaTronic electronic control (optional) ensures correct motor rotation even if phases are misconnected, and provides protection from overload, overheating, phase loss, and clogging, with USB-based diagnostic access
Plug-and-pump ready, with built-in contactor and thermal protection—no external control gear needed
Designed for robust, reliable operation even at low water levels or during intermittent duty
Key Characteristics
Compact and portable (approximately 59 kg / 130 lb without cable), slim enough for constrained jobsite use
Durable ductile iron hydraulics built for abrasive, contaminated fluids
Dual mechanical shaft seals in oil bath—silicon carbide surfaces ensure excellent abrasion resistance and long service life
Long-interval serviceability: modular hydraulic and motor components, top-access junction box, and oil inspection ports
Energy-efficient motor and hydraulics , paired with low-friction bearings and environmentally safe oil in the oil casing
Core Performance Highlights
Capable of moving up to 25 L/s (~1,500 L/min or ~400 GPM) and delivering head up to around 28 m (~90 ft) at 50 Hz
Accepts solid particles up to approximately 48 × 60 mm, making it ideal for sludge, slurry, or grit-laden water
Maximum 30 starts per hour , supporting level-activated cycles without overheating
Designed for continuous duty in fluids up to ~40 °C (104 °F), with density up to ~1,100 kg/m³ and pH between 5–8
Protection rating: IP 68 with maximum submergence capability of ~20 m (65 ft)
