When deep-pit excavation, open-pit mining, or high-rise basement construction demands relentless water clearance against high vertical lift, equipment reliability is non-negotiable. The Tussu® SH Series high-head submersible dewatering pump is engineered specifically for these high-pressure, abrasive environments, delivering continuous 24/7 operational uptime where standard drainage pumps fail.
Technical Specifications & Performance Curves Overview
The Tussu® SH Series features an advanced hydraulic design optimized for both 50Hz and 60Hz power grids, offering seamless global deployment for international contracting teams.

Key Performance Advantages of the Tussu® SH Series
1. Functional Performance Drop-In Replacement for Tsurumi LH Models
For contractors looking to optimize project procurement costs without sacrificing structural integrity, the Tussu® SH series serves as a direct functional equivalent to mainstream high-head drainage pumps like the Tsurumi LH model. It perfectly matches the original curves for rated head, maximum flow capacity, and flange connection dimensions.
Technical Note on Spare Parts: While the Tussu® SH series offers identical on-site hydraulic performance and drop-in installation, its internal mechanical spare parts are proprietary and not interchangeable with Tsurumi. This allows us to maintain strict material quality control and offer highly competitive component pricing directly from our factory.
2. High-Chrome Alloy Metallurgy for Severe Wear Resistance
Pumping grit-laden groundwater accelerates impeller wear. The SH Series mitigates this with premium material selection:
-
Impeller: Hardened Chrome Steel that resists erosion from suspended solids and abrasive sand.
-
Volute & Diffuser: Heavy-section Cast Iron absorbing high kinetic impacts.
-
Mechanical Seals: Dual silicon carbide-to-silicon carbide (SiC/SiC) mechanical seals isolated in a dedicated oil chamber, preventing moisture ingress into the motor casing even under deep submersion pressures.
3. Versatile Solid-Handling Impeller Passages
From clean, deep-well water bypass to heavy stormwater runoff containing silt, the SH series provides distinct configurations:
-
6 mm Passage (SH422, SH430, SH637, SH645): Engineered for ultra-high-head municipal and industrial drainage.
-
15 mm to 20 mm Passage (SH622, SH630, SH837, SH845): Built for civil engineering, tunneling, and basement dewatering where larger suspended particles are unavoidable.
Primary Industrial B2B Applications
-
Mine Dewatering: Efficient handling of abrasive mine water accumulation in open-pit and deep-shaft operations.
-
Civil Engineering & Tunneling: High-pressure water transfer out of deep foundation pits, subway shaft excavations, and cofferdams.
-
Municipal Infrastructure: Flood control, high-volume stormwater drainage, and emergency bypass pumping.
