Why Choose the Sulzer XJ 25 Submersible Pump?
The XJ 25 is ideal for demanding dewatering tasks in construction , mining , tunneling, and site drainage:
Built‑in AquaTronic control ensures correct impeller rotation , avoiding wear, and provides overload, phase‑loss and over‑temperature protection.
Slim, compact design (≈ 39 kg) allows easy transport and quick installation in tight sump areas.
Plug‑and‑pump operation—no external panel needed. Features include anti‑clog backspin, automatic restart, and optional level control.
Durable construction: white‑cast‑iron impeller and wear ring, nitrile‑coated volute, adjustable rings for long wear life.
IEC‑efficient motor (IE2/IE3) with low‑friction bearings reduces energy consumption and operational cost.
Up to 30 starts per hour capability ensures suitability for intermittent operation or level‑controlled start/stop.
Technical Specifications of XJ 25
Motor power: 2.5 kW (50 Hz) or 2.9 kW (~4 hp at 60 Hz)
Max flow / head: ~19 L/s and 26 m (50 Hz); ~20 L/s and 30 m (60 Hz)
Solids handling: light abrasives up to ~7 mm
Weight: ≈ 39 kg (without cable)
Protection: IP 68; rated for submergence to ~20 m
Medium limits: density ≤1100 kg/m³; pH 5–8
Cycle rate: up to 30 starts/hour

When to Consider Upgrading to the XJ 40
If your site requires higher flow or head:
Motor power: 3.7 kW (50 Hz); 4.3 kW (~6 hp at 60 Hz)
Performance: ~23 L/s and 34 m (50 Hz); ~22 L/s and 36 m (60 Hz)
Weight: ~42 kg
Maintains the same AquaTronic control, IP 68 rating, 20 m maximum submergence, pH 5–8 range, and strainer size of ~7.5 × 22 mm.
The XJ 25 is a compact, energy‑efficient, and intelligent submersible pump that performs reliably in harsh dewatering environments. It is perfect where portability, automation, and low service needs are priorities. If you need increased flow or higher head, the XJ 40 delivers that while preserving the same rugged features and smart controls.
