Tsurumi LH Series Submersible Pump

The Tsurumi LH Series Submersible High-Head Pump represents the pinnacle of heavy-duty site dewatering, specifically designed to meet the extreme demands of deep underground mining, tunnel excavation, and high-pressure civil engineering projects.

Constructed with a slimline, cylindrical motor casing, the LH series allows liquid to pass around the motor housing before discharging at the top. This top-discharge flow-through design ensures optimal motor cooling during low-water conditions and allows the pump to be lowered directly into narrow sumps, boreholes, and tight drainage shafts.

Key Features & Benefits

• Extreme High-Head Performance: High-pressure multi-stage impeller options capable of pumping against extreme elevation heads.
• Slim Top-Discharge Design: Compact cylindrical structure fits into narrow casings and provides continuous motor cooling via pumped liquid.
• High-Chromium Iron Impellers: Exceptional resistance to abrasive wear from quartz, slurry, sand, and mining debris.
• Double Inside Mechanical Seal: Features silicon carbide seal faces enclosed in an oil chamber for ultimate protection against high water pressure ingress (permits operation in water up to 100m depth)
• Patented Oil Lifter: Ensures continuous lubrication of seal faces even under partial oil volume or low-level operation.
• Constructed of cast iron, the centre discharge design reduces the base area size and facilitates locating and positioning in confined spaces.
• Supplied with 20 metres of heavy duty, H07RN-F rubber power cable, although IDS (individually screened cable) is available, at an extra cost, on most models, for quarry and mining applications.

Applications

• Deep shaft dewatering in underground mining and tunneling
• High-elevation water transfer on large construction sites
• Quarrying, aggregate washing, and abrasive slurry pumping
• Civil engineering projects requiring long-distance drainage discharge

Note: Due to the high head pressures and motor capacities of the LH series, proper power supply sizing and discharge hose pressure ratings must be verified prior to installation. Contact our technical team for assistance.
