LH-W Series – Submersible High-Head Drainage Pumps
Max Flow Rate: 33.3L/sec (2m3/min)
Head Max: 215m
Deep well and high-head dewatering for mining, industrial and construction industry
The LH-W-series is a three-phase cast iron extra high head drainage pump having dual impellers. Being the pump cylindrical and slim, it can be installed in a well casing for deep well dewatering. The centre flange construction assures a stable installation even if it is fixed by the discharge pipe.*1 The top discharge, flow-thru design provides maximum motor cooling efficiency allowing continuous operation at low water levels and extended dry-run capability. The pump incorporates seal pressure relief ports that prevent the pumping pressure from applying to the shaft seal.*2
