LH & LH-W (1000V) Series – Submersible Drainage Pumps
Underground mining drainage pump using 1000V
The LH & LH-W 1000V 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.
Features
- 1000V Cable for demanding underground mining applications, improving operational efficiency
- Top discharge, flow-thru design allows pumped liquid to cool the motor for reliable operation at low water levels
- Seal pressure relief port protects the mechanical seal from excessive pump pressure while submerged, helping to improve seal life and long-term reliability (excludes LH4110W)
- Anti-wicking cable entry system prevents water ingress, protecting internal components
Typical Applications
- Underground Sumps & Pump Stations
- Fish Tanks (Water Containment Tanks)
- Water Transfer
- Tunnelling and underground works
