Industrial Grade Pumping Excellence

Our 1 2 hp deep well submersible pump series sets the gold standard in the general equipment manufacturing sector. By utilizing 50W400 grade high-quality cold rolled silicon steel and high-speed punch stamping, we ensure exceptionally low stator iron loss and minimized self-heating for continuous industrial operation.

Engineered for extreme environments, the pumps feature 3CR13 stainless steel impeller shafts and high-temperature durable bushings. This technical synergy allows for seamless integration with frequency converters, automatically adjusting to water consumption and ensuring a lifespan that far exceeds industry averages.

Advanced Core
Engineering Pillars

Three fundamental technological advantages that ensure unmatched reliability in deep-well water extraction.

Premium Metallurgy

Utilizing high-grade alloys to prevent corrosion and mechanical wear in deep well environments.

  • 3CR13 Steel: Anti-corrosive impeller shaft for longevity.

  • Durable Bushings: High-temperature resistance for continuous load.

Wet Submersible Tech

A sophisticated water-filled motor structure that provides natural cooling and lubrication.

  • Water Lubrication: Reduces friction and extends bearing life.
  • Pressure Film: Balances internal expansion and contraction.
  • High-Insulation: Specialized winding for anti-aging performance.

Precision CAD Design

Computer-optimized hydraulics ensure the best flow-to-power ratio in the market.

  • Optimized Impellers: Minimal cavitation risk.
  • Sand Prevention: Dual oil seals and sand rings.
  • Balanced Torque: Reducing vibration during start.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries about our pumps.

1

What is the ideal operating depth for these pumps?

Our 1 2 hp deep well submersible pump series can operate at diving depths up to 70m, provided the pump bottom remains at least 3m above the well floor.

2

Can the pump be used with frequency converters?

Yes, they are specifically designed to work with frequency converters, allowing the flow rate to be automatically adjusted based on real-time water consumption.

3

How do I prevent the motor from overheating?

Ensure the motor cavity is completely filled with clean water before use and that the pump is fully submerged to allow the water-filled wet structure to cool the motor effectively.

4

What water quality is required for the pump?

The pump is designed for clean water: PH value between 6.5-8.5, chloride ion content ≤ 400mg/L, and solid impurities ≤ 0.01% mass ratio.

5

How often should the pump be maintained?

We recommend dismantling for maintenance after one year of operation or every two years of diving time to replace worn parts like impeller shafts and sealing rings.

6

Can the pump run without water?

Absolutely not. Running the pump without water (no-load test) is strictly prohibited as it can lead to immediate bearing failure and motor burnout.
