Series XRW 210

Sulzer submersible mixer XRW 210

Compact submersible mixer, designed to achieve an optimum flow pattern in a wide range of mixing and stirring applications, in large tanks and open waters.


The submersible mixer is designed as a compact, water-pressure-tight unit, with propeller and mounting bracket which allows for vertical and horizontal adjustment. A mounting kit for attachment to a square guide rail is also available. A flow ring is fitted on selected models. The mixer is available in cast iron (EC) and stainless steel (CR) versions.


Premium Efficiency IE3, three-phase, squirrel-cage motor; 400 V*; 50 Hz; 4-pole. Protection type IP 68, with stator insulation Class H. Start-up: direct on line (DOL) Max. submergence 20 m. * other voltages available


Technically optimized, axially operating 2- or 3-blade propeller, designed to achieve high thrust and therefore a high flow capacity in an axial direction. The propeller is self-cleaning and so ensures vibration-free operation.

Solids deflection ring

The patented solids deflection ring protects the mechanical seal from damage by ingress of solid or fibrous matter.


All bearings are lubricated-for-life and maintenance-free, with a calculated lifetime of more than 100,000 h.

Shaft sealing

Sic-Sic mechanical seal at medium side.
Optional lengths (m): 15, 20, 30, 40, 50.


Explosion-proof version, additional seal (Sic-C) at motor side, flow ring, seals in viton, EMC cable, PTC thermistor in stator, vertical angle adjustment, vortex shield, lifting hoop, guide rail bracket, vibration damper.
NBR O-rings and lip seals.

Seal monitoring

DI-system with sensors in the oil**, motor, and cable connection chambers.

Temperature monitoring

Thermal sensors in the stator which open at 140 °C.


10 m sewage-resistant CSM material, type S1BN8-F.
