Submersible drainage pump XJ

Drainage solutions reduce water-related downtime

The submersible drainage pump XJ is ideal for pumping water and dirty water mixed with light abrasives. Pumps with built in AquaTronic unit will always have correct direction of impeller rotation, ensuring peak performance and reduced wear.

MAIN BENEFITS

Plug-and-pump installation without having to worry about overheating

Reliable, trouble-free operation also at low water levels

Pumps with built-in AquaTronic unit will adjust incorrect phase order, ensuring correct impeller rotation

Modular design increases serviceability and makes it easy to convert the pump for different hydraulic requirements

Pumps with built-in AquaTronic can be checked without disassembly, using its service software

Designed for difficult application environments with abrasives and small solids

Innovative design that allows for easy conversion from high head to high flow

MAIN APPLICATIONS

Drainage & Flood control projects

Construction site dewatering

Pumping of water and dirty water mixed with light abrasives

Difficult application environments with abrasives and small solids (XJ 900)

Instead of a built-in contactor, an optional AquaTronic unit can be used. The AquaTronic unit compensates for incorrect phase order, which ensures correct motor rotation every time.
The pump XJ 900 is fitted with impellers and diffusers for both HD and ND versions. When connected in series they give high head and when connected in parallel they give high volume. This innovative design with dual impellers allows for a quick and simple conversion between hydraulic performance options, reducing the need to addition inventory to cover the range. Both high head and high flow versions use the same two impellers.
For XJ 25, XJ 40, XJ 50, XJ 80 and XJ 110, the conversion between high-volume and high-head hydraulics is managed with only a few parts, ensuring the right performance for the application.
Impellers and wear rings in white cast iron, as well as diffusers coated in oil-resistant nitrile rubber, provide high abrasion resistance. For XJ 900, the impellers are built back-to-back together with double exit volutes which gives low axial forces and secures long bearing life.
Double mechanical shaft seals in an oil bath, with primary seal surfaces in silicon carbide and secondary seal surfaces in silicon carbide on carbon, extend the life of the pump. A double cable-entry seal system increases the protection against moisture entering the electrical junction area. A double outer casing and good heat convection enable the pump to operate continuously at low levels – or even run dry without damaging the motor.
Due to the modular design, the same parts can be used for different pumps, which lowers the overall service costs. The adjustable wear ring ensures proper clearance throughout the impeller lifetime. External inspection ports for the oil and motor chambers enable quick and easy evaluation of the shaft seal during service. By removing the top cover of the pump, the electrical junction area can easily be checked.
The high-efficiency motor and new hydraulics combine with low-friction bearings to reduce power losses. The result is low total energy costs and minimized carbon footprint.
