When your project demands serious vertical lift, standard drainage pumps simply won’t cut it. Deep-well pre-dewatering, deep open-pit mining, and high-elevation civil engineering require a specialized breed of equipment.
The TUSSU® SH Series High-Head Submersible Dewatering Pump is engineered precisely for these heavy-duty, high-pressure environments. Designed as a rugged, highly reliable, and cost-effective equivalent to the industry-standard Tsurumi LH series, the TUSSU® SH series delivers identical hydraulic performance and uncompromising durability without the premium price tag.

Why Site Managers Choose the TUSSU® SH Series Over Traditional Alternatives
1. Direct Tsurumi LH Equivalent Hydraulic Matching
Upgrading or replacing existing high-head pumps shouldn’t mean re-engineering your entire setup. The TUSSU® SH series fully matches the Tsurumi LH model’s hydraulic curves. You get the exact same flow rates and pressure characteristics, making it a seamless, drop-in alternative for fleet managers looking to optimize capital expenditure (CAPEX) without sacrificing operational efficiency.
2. High-Chrome Cast Iron Hydraulics (≥ 58 HRC)
Pumping dirty water filled with abrasive sand, gravel, and slurry destroys standard ductile iron impellers in weeks. TUSSU® SH pumps feature closed impellers made from high-chrome cast iron, treated to a hardness of at least 58 HRC. This extreme wear resistance ensures consistent, long-term performance and minimizes the total cost of ownership (TCO) in highly abrasive environments.
3. Premium Double SiC-SiC Mechanical Seals
The mechanical seal is the lifeline of a submersible pump. Instead of relying on cheap carbo-ceramic materials, the SH series utilizes premium double Silicon Carbide to Silicon Carbide (SiC-SiC) mechanical seals. This provides superior hardness, low friction, and an airtight barrier against water ingress, even when operating under the immense pressure of a 30-meter submergence.
4. Continuous Self-Cooling Top-Outlet Design
Space is a premium in deep-well casings and narrow bypass trenches. The slim, top-outlet design of the SH series allows it to fit into tight spaces effortlessly. More importantly, the pumped water travels around the motor jacket before discharging. This continuous flow ensures the motor remains cooled even during intermittent dry-run conditions or when the pump is only partially submerged.
Core Applications
The TUSSU® SH series is built for heavy industries where downtime is not an option:
-
Mining & Quarries: Efficiently handles high-lift dewatering in deep pits, coal mines, and abrasive mineral slurries.
-
Civil Engineering & Deep Foundations: Ideal for deep-well pre-dewatering during large-scale excavations and subway constructions.
-
Industrial Water Management: High-volume, high-pressure bypass and transfer inside factories, water treatment plants, and reservoirs.
