Why Choose the Sulzer XJS 25 Sludge Pump
Engineered for pumping sludge and heavily contaminated water containing solids and abrasives.
Features a free‑flow vortex impeller design to ensure clog-free operation even when handled at low water levels or with suspended solids.
Available with AquaTronic electronic control, which corrects phase order automatically, protects the motor from overload, overheating, phase loss, and provides anti‑clog reversal. USB diagnostics allow access to operating history, fault logs, and service data.
Operates as a plug‑and‑pump unit, ready to run without external starter panels.
Designed for continuous, reliable operation even in slurping conditions when the intake is near or below the surface.
Key Characteristics
Compact and lightweight (approximately 39 kg / 86 lb without cable), making it easy to transport and position.
Slim yet robust construction with dual-layer housing and efficient heat dissipation to prevent thermal damage during low fluid operation.
Integrated level sensor allows automatic stop/start cycles to save energy and prevent dry-running.
Maintenance-friendly: modular hydraulic and motor design, accessible service ports in the oil casing, and diagnostics accessible via USB (AquaTronic versions).
Hydraulics and motor are optimized for high efficiency and low friction, keeping power draw and energy costs low.
