Why Choose the Sulzer XJS 40 Sludge Pump?
Specifically designed for pumping sludge-laden or abrasive dirty water that contains solids.
Features a free‑flow vortex impeller and volute that prevent clogging and allow operation even at low water levels.
Available with the AquaTronic electronic control unit, which ensures correct impeller rotation regardless of phase wiring, provides motor protection (overload, phase loss, high temperature), anti‑clog reverse spin, and supports plug‑and‑pump start‑up.
Ready for deployment straight out of the box—no external control panel required.
Built for continuous, trouble‑free operation under demanding sludge-pumping conditions.
Key Characteristics
Lightweight and slim (~41 kg / 90 lb), making it easy to transport and position in tight or remote job-site environments.
Effective thermal management via dual housing construction permits operation even when submerged minimally or intermittently.
Integrated level sensor option enables automatic stop/start based on fluid level to guard against dry running.
Designed for simplified field servicing: modular assembly, oil-bath seal inspection ports, and diagnostics available via USB when equipped with AquaTronic.
Hydraulics and motor engineered for high efficiency and low wear, with durable materials suited for abrasive media.
