product feature

front shroud

Energy-saving and efficient, green and environmental protection

Efficiency index reaches international advanced level, energy efficiency index reaches MEI 0.7.

blade

Compact structure, safe and reliable

Under the same flow head parameters, the pump height is lower, the vibration is smaller, the noise is lower, the space is smaller, and the weight is lighter.

back shroud

Durable and easy to repair

Special configuration of modular mechanical seal is adopted to ensure smooth operation and no leakage in slight vibration and impact environment. At the same time, the mechanical seal position is designed to be sufficient for disassembly and assembly.

Space, convenient maintenance, in the replacement of the machine seal, without dismantling the pump.

Precision manufacturing, quality first

Stainless steel cold drawing stamping welding impeller, guide vanes, middle and other important parts, flow parts smooth flow channel, strong corrosion resistance, high efficiency, generally 5%-10% higher than the casting pump efficiency, impeller by the front cover plate, blades, rear cover plate welded. KQDP40 series blades have protruding solder joints. When large current passes between blades and front and rear cover plates, high temperature is generated at the bumps due to high contact resistance, which makes the bumps melt into one body with high welding efficiency. Impeller rear cover plate due to the small thickness of the plate, punch a spline groove, impeller by spline shaft connection torque transmission. A plurality of grooves of the rear cover plate are stressed, so that the working reliability is improved. KQDP50 series impellers are welded by robot laser, and the strength of joints is much higher than that of steel plate base metal.

Efficient motors, pursuit of excellence

Fully enclosed self-fan cooling squirrel cage type high-efficiency three-phase asynchronous motor, 2%-10% higher efficiency than ordinary motor. Motor bearings come standard with imported SKF bearings or NSK bearings. NSK bearings are used for motor power below 4kW (including 4kW), SKF bearings are used for motor power above 5.5kW (including 5.5kW),

Inlet and outlet flanges in the same straight line, installation is more convenient

KQDP25, 32, 40 standard round flange, optional cast iron oval flange (threaded connection).

KQDQ25, 32 standard round flange, optional bayonet type, outer tube thread connection. KQDQ40 comes standard with round flange and optional bayonet coupling.

KQDP/Q50, 65, 80, 100 standard round flange, KQDQ50 optional bayonet coupling.

Kaiquan KQDP/Q multistage pump is a centrifugal pump with superior performance and compact structure. The following is a detailed analysis of its characteristics:

Energy saving:

The KQDP/Q multistage pumps have been carefully designed and optimized for efficient performance and significant energy savings.

Wide range of application:

The pump is suitable for building water supply, boiler water supply, air conditioning cooling, hot water circulation, fire fighting and other occasions.
It can transport clean water or liquid similar to clean water, and the liquid temperature can reach 105 degrees Celsius at high temperature and-20 degrees Celsius at low temperature.

Advanced seal design:

Pump shaft seal adopts integrated mechanical seal, no leakage, ensure the safety and reliability of operation.
Mechanical seal maintenance is convenient, replacement does not need to disassemble the pump body, greatly reducing the maintenance cost and time.

Excellent motor configuration:

Equipped with the motor for the Y2 series fully enclosed fan cooling squirrel cage three-phase asynchronous motor, with high efficiency, energy saving, low noise and other characteristics.
The voltage of the motor is 380V, the frequency is 50HZ, the protection class is IP55, and the insulation class is F, which ensures the stable and reliable operation of the motor.
