Dewatering Pump Tsurumi LH430 is a submersible general dewatering high head pumps for deep well.
Features :
- Cylindrical channel
The entirely cylindrical drive channel maintains the motor cooling efficiency adequately high even during operations at a low water level. Also, with the discharge port on its top (sketch), the pump can be installed in a narrow place. - Dual impeller
Enables the pump to be lifted up/ down without disconnecting it from piping and stably installed true to the center of gravity
Dewatering Pump Tsurumi LH430 for deep – well pre – dewatering or high – head dewatering in civil engineering and construction works.
