Product Description
The SP series is a high-capacity deep well water pump engineered for demanding extraction from standard and large-diameter wells. Constructed from corrosion-resistant stainless steel (304/316), the deep well pump guarantees water purity and delivers exceptional longevity across diverse groundwater conditions. Capable of surpassing 500 meters in head and handling substantial flow rates, this industrial-grade stainless steel deep well submersible pump meets the needs of large-scale irrigation, municipal water supply, mine dewatering, and major fluid transfer operations.
Product Features
High-Efficiency, Multi-Stage Hydraulics: As the core of the deep well pump is an optimized multi-stage centrifugal system designed to deliver large flow volumes from significant depths, focusing on sustained high performance and energy savings under continuous heavy loads.
Complete Stainless Steel Wetted Parts: All internal components in contact with water-including the shaft, impellers, diffusers, and intake-are fabricated from stainless steel. This eliminates corrosion risks, ensures hygienic water output, and provides excellent resistance to abrasion from sandy water.
Modular Pressure Configuration: The output pressure of this deep well water pump is not fixed. It can be custom-configured at the factory by assembling the precise number of impeller stages required, allowing exact matching to the well's dynamic water level and system pressure demands.
Built-In Protective Features: Includes an integral stainless steel check valve to prevent water hammer and reverse rotation upon shutdown. A durable stainless steel intake screen offers primary protection against larger particulate matter.
Engineered for Continuous Deep-Well Service: Built to tolerate submersion depths up to 70 meters and endure continuous high-pressure operation, the stainless steel deep well submersible pump is crafted for decades of dependable service within critical water supply infrastructure.

FAQ
Q: What are the main reasons for choosing a stainless steel deep well pump?
A: Primary reasons include: superior corrosion resistance for groundwater with potentially corrosive elements; a hygienic and eco-friendly material that safeguards drinking water quality; high strength and durability for prolonged deep well operation; and relatively lower maintenance costs. For demanding applications, a stainless steel deep well submersible pump represents a premium, long-term investment.
Q: Why is a minimum 3-meter clearance from the well bottom necessary during installation?
A: This distance is primarily maintained to prevent the intake from drawing in sand, silt, and sediments settled at the well bottom, which can cause impeller wear and clogging. Drawing from cleaner water strata above extends the deep well pump's operational life and helps maintain water quality. This guideline is essential for both stainless steel and standard electric deep well pump installations.
Q: How is the head related to the number of stages in a deep well water pump, and how is the model selected?
A: The total head is directly and primarily determined by the number of impeller stages. Each stage contributes a specific head increment, and the total head is approximately the sum of these increments. For selection, calculate the total dynamic head required (elevation from dynamic water level to discharge point plus all pipeline friction losses). Then, refer to the pump's performance curves to choose a model and stage count that meets these requirements. Professional consultation is advised for high-head deep well pump applications.
