SH Series High-Head Submersible Drainage Pumps

The SH Series is engineered for contractors and engineers who require high-pressure water displacement in the most demanding environments. Covering a power range from 2.2kW to 45kW, these pumps are the go-to solution for deep-well dewatering, mining, and large-scale civil engineering projects.

Comprehensive Model Specifications

We offer a full range of SH models designed to balance flow rate and discharge head requirements. Below are our core configurations:

Model	Outlet (inch)	Output (kW)	Max Head (m)	Max Flow (m3/h)
SH422 / SH622	4″ / 6″	22	70 – 90	100 – 150
SH430 / SH630	4″ / 6″	30	90 – 110	120 – 180
SH637 / SH837	6″ / 8″	37	100 – 120	150 – 240
SH645 / SH845	6″ / 8″	45	115 – 140	180 – 300

Selection Tip: Models like the SH430 are optimized for extreme vertical lift (High Head), while the SH845 is designed for high-volume water transfer (High Flow) at significant depths.

Technical Advantages for Industrial Use

• Extreme High-Head Performance: With power ratings up to 45kW, the SH series can reach heads exceeding 100 meters, overcoming gravity in deep mining shafts and high-rise construction sites.

• Ductile Iron & High-Chrome Construction: To handle abrasive solids and sandy water, the impeller and suction plate are cast from high-chrome alloy, significantly extending the wear life compared to standard aluminum or cast iron pumps.

• Advanced Motor Cooling: The slimline, top-discharge design ensures the motor is cooled by the pumped fluid, allowing for continuous operation even when partially submerged.

• Dual Mechanical Seals: Equipped with premium Italian or Japanese-standard mechanical seals in an integrated oil chamber, ensuring 24/7 protection against leakage.

Applications

• Open-pit and Underground Mining: Reliable dewatering of abrasive slurry and runoff.

• Infrastructure Projects: Tunneling, bridge cofferdams, and deep foundation drainage.

• Disaster Relief: High-capacity urban flood control and emergency drainage.

• Industrial Plants: Efficient handling of sediment-laden process water.

Why Global Projects Trust Tussu SH Series？

At Tussu Pump, we don’t just manufacture hardware; we deliver dewatering reliability. The SH series represents our commitment to “Interchangeability, Durability, and Efficiency.” Here is how Tussu SH pumps are performing in the field:

Case Study 1: Deep-Level Iron Mine Dewatering (Argentina)

• The Challenge: A Tussu client in South America needed to clear groundwater from an iron mine at a vertical depth of 110 meters. The water was highly abrasive, containing iron ore particles that quickly eroded standard cast iron pumps.

• The Tussu Solution: We supplied the Tussu SH645 (45kW).

• The Result: By utilizing Tussu’s signature High-Chrome (27%) alloy impellers, the SH645 operated for over 3,000 hours without a drop in performance. The client noted that Tussu’s parts were 100% interchangeable with their existing high-head fleet, simplifying their maintenance inventory significantly.

Case Study 2: Rapid Urban Flood Response (Southeast Asia)

• The Challenge: A municipal emergency department required a high-volume pump that could be quickly deployed during flash floods. The pump needed to handle large debris while fitting into standard drainage manholes.

• The Tussu Solution: A fleet of Tussu SH837 (37kW) and SH845 (45kW) pumps was deployed.

• The Result: The slimline top-discharge design allowed for rapid installation in confined urban spaces. With a discharge capacity of up to 300 $m^3/h$, Tussu pumps successfully cleared flooded intersections 40% faster than the department’s previous equipment, preventing significant property damage.

The Tussu Advantage: Engineering Excellence

Why do procurement managers specify Tussu SH Series for their critical operations?

1. Precision Engineering: Every SH422 to SH845 model is built to exact tolerances, ensuring that when you replace a wear part, it fits perfectly—no onsite modifications required.

2. Advanced Thermal Protection: Tussu pumps feature integrated sensors that automatically shut down the motor in case of dry-running or phase failure, protecting your investment.

3. Field-Tested Materials: From the ductile iron casing to the dual silicon carbide mechanical seals, every component is selected for long-term immersion in harsh industrial liquids.
