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

Special note: 1, elliptical flange connection pressure grade 1.6MPa and below, greater than 1.6MPa please choose circular flange connection;

2. All standard flanges shall comply with GB/T17241.6-2008 design standard, pressure grade PN 2.5 MPa;

3. Pairing flanges and pipe clamps for pipeline connection shall be ordered separately.

The advantages of Kaiquan KQH chemical pump are mainly reflected in the following aspects:

Energy saving:

KQH chemical pump adopts excellent hydraulic model, after unique improvement and CAD optimization, the whole pump operation efficiency is higher.

Structural design and materials:

Simple structure, strong reliability and convenient maintenance. Pump body, pump cover, impeller and other parts blank precision casting, to ensure the size accuracy and smoothness of the flow channel.
Pump shaft adopts split shaft design, special clamping structure, high concentricity, small vibration, reliable use.

Maintenance and operation:

Easy maintenance: replace the machine seal, impeller without moving the pipeline, especially in the motor power is large, replace the machine seal without moving the bracket and motor, making maintenance easy and fast.
Convenient pipeline connection: pump inlet and outlet diameter is the same, and located in the same straight line, convenient pipeline installation and connection.

Strong versatility:

Pump parts overall series versatility, the use of national standard vertical, horizontal motor and the series of pump cover, pump shaft, connecting frame and other parts, so that the whole series has the greatest versatility.

Widely used in industry:

Suitable for chemical, petroleum, metallurgy, papermaking, food, pharmaceutical, synthetic fiber and other industrial sectors, used for conveying corrosive, viscosity similar to water medium.

Performance parameters:

This series of pumps has a wide range of flow, from 2.2 to 240m/h; high lift, from 2.8m to 87m; wide medium temperature range,-10℃ to 80℃; working pressure up to 1.6Mpa.

To sum up, Kaiquan KQH chemical pump has significant advantages and competitiveness in the industrial field, especially in the chemical industry, due to itsenergy-saving, reasonable structural design, convenient maintenance, strong versatility, wide industry application and excellent performance parameters.
