SHANGHAI KAQUAN KQDP25-1-17 Light Vertical Multistage Stainless Steel Centrifugal Pump

(For Tap Water Supply & Non-Negative Pressure Water Supply)

SHANGHAI KAQUAN PUMP GROUP CO., LTD.

KQDP25-1-17 is the 3rd-generation light vertical multistage centrifugal pump by Shanghai Kaiquan,

. All wetted parts are

with stamping & welding structure, featuring high efficiency, hygiene, stability, and reliability. It is the ideal core booster for municipal water supply, building secondary water supply, and industrial pure water systems

.

• KQDP: Kaiquan Light Vertical Multistage Pump (SS wetted parts)
• 25: Inlet/outlet diameter (25mm)
• 1: Single-stage impeller design
• 17: Rated head approx. 17m

• Flow Rate: Approx. 2.5–6 m³/h (typical: 4–5 m³/h)
• Rated Head: 17m
• Motor Power: 0.55kW / 0.75kW
• Voltage: 380V/50Hz (single-phase optional)
• Speed: 2900r/min
• Liquid Temp: -20°C to 70°C (hot water version up to 120°C)
• Wetted Material: 304 stainless steel (impeller, diffuser, stage casing, shaft)
• Shaft Seal: Cartridge mechanical seal (leak-free, maintenance-free)
• Application: Vertical installation, pipeline direct connection, suitable for non-negative pressure booster sets

1. Hygienic Stainless Steel, No Secondary PollutionImpeller, diffuser, and casing made of 304 stainless steel by precision stamping and welding. Smooth flow passage, corrosion-resistant, rust-free, and compliant with drinking water standards. Ideal for tap water, pure water, and food-grade media.
2. High Efficiency & Energy Saving (MEI ≥ 0.7)Advanced hydraulic design, 5%–10% higher efficiency than traditional cast pumps. Equipped with high-efficiency motors, 2%–10% more energy-saving than standard motors, significantly reducing long-term operating costs.
3. Compact, Low Noise, Low VibrationVertical multistage structure for smaller footprint, lighter weight, and lower profile. Precision dynamic balancing ensures smooth operation with low noise (≤60dB) and minimal vibration.
4. Optimized for Non-Negative Pressure SupplyDirectly connectable to municipal pipe networks. Works with steady-flow compensator and vacuum suppressor to achieve pressure-superposed boosting without creating negative pressure, protecting the municipal network. Fully enclosed operation eliminates secondary pollution from water tanks.
5. Maintenance-Free & Easy ServiceStandard cartridge mechanical seal allows seal replacement without removing the pump or piping. imported SKF/NSK bearings ensure long service life and extremely low failure rate.
