LH-Series - High-Head Dewatering Pumps (Single Impeller)
The LH-series is a submersible three-phase cast iron high head drainage
pump. Being the pump cylindrical and slim, it can be installed in a well
casing for deep well dewatering. The center flange construction assures
a stable installation even if it is fixed by the discharge pipe. 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.*
