1 Lowara Rewindable motors LW - L8W - LW - L12W Series

maximum thrust Protection class: IP8 WRAS approved

2 Superior thrust bearing design: performances higher than NEMA Standard Bidirectional motor operation at maximum thrust Protection class: IP8 WRAS approved cables Stator easy to rewind Different versions available on request

The thrust bearing is designed to support the maximum thrust of the pump in the worst conditions Horizontal and vertical installation* Mechanical seal as standard Carbon/Ceramic All the thrust

3 The thrust bearing is designed to support the maximum thrust of the pump in the worst conditions Horizontal and vertical installation* Mechanical seal as standard Carbon/Ceramic All the thrust bearings are designed to support the maximum axial load up to 22 kw000 N from 2 kw to 37 kw N N and N The outside pressure is compensated internally by the use of a special membrane which works with a non-return valve that does not allow water to enter the motor from the borehole well. The cable supplied complies with WRAS (Water Regulation Advisory Scheme - BS 920) Maximum allowed voltage fluctuation 00 V +/-% Rewindable stator: the design of the winding heads are easy to inspect and repair Suitable to operate with variable frequency inverter* Available on request: High temperature HT Sand protection Different materials PT0 * See the limits reported in the instruction manual

4 Mechanical seal as standard Upper and lower carbon bearing bush Stator Easy to Rewind Wet rewindable stator Up thrust ring included Kingsbury bi-directional axial thrust bearing
