Application Case Studies & Customer Experience

The real-world performance of the 175QJR Deep Well Submersible Pump is best illustrated through successful deployments and positive client feedback. These case studies highlight the tangible benefits delivered in diverse industrial settings.

Case Study 1: Municipal Water Supply Upgrade (Large City, Southeast Asia)

**Challenge:** A major city faced increasing demand for potable water and struggled with aging, inefficient deep well pumps, leading to high energy costs and frequent breakdowns. The existing infrastructure could not meet peak demand, resulting in water shortages in certain districts.

**Solution:** After a detailed hydrogeological survey and system analysis, five 175QJR Deep Well Submersible Pumps (each rated at 150 kW, 250 m head, 180 m³/h flow) were installed to replace the legacy units. The pumps were specified with SS316 components due to local groundwater characteristics and integrated with VFDs for optimized flow control.

**Results:** Within the first year, the city reported a 28% reduction in energy consumption for the well field, translating to significant operational savings. Water delivery became more consistent, eliminating prior shortages. The robust construction and VFD integration led to a substantial reduction in maintenance costs and downtime, improving the overall reliability of the municipal water supply system. Customer feedback emphasized the "unwavering reliability" and "tangible energy savings."

Case Study 2: Industrial Cooling Water for a Steel Mill (North America)

**Challenge:** A large steel manufacturing plant required a continuous, high-volume supply of cooling water from deep wells. The existing pumps suffered from rapid wear due to abrasive particles in the well water and corrosion from slightly aggressive water chemistry, leading to constant repairs and production interruptions.

**Solution:** Two customized 175QJR Deep Well Submersible Pumps were deployed. These units featured impellers and diffusers made from hardened SS316 with specific anti-abrasion coatings, and the motor casing was upgraded to a higher-grade stainless steel for enhanced corrosion resistance. Remote monitoring sensors were installed to track vibration and temperature in real-time.

**Results:** The customized 175QJR pumps demonstrated a remarkable increase in service life, operating continuously for over 3 years without significant maintenance, compared to the previous pumps which required interventions every 6-9 months. The enhanced material selection and coatings effectively resisted both abrasion and corrosion. The client lauded the "exceptional durability" and "significant reduction in operational headaches," allowing them to focus on core steel production.
