Horizontal Centrifugal Pump

Horizontal Centrifugal PumpProduct Overview

DFW type DongfangHorizontal Centrifugal PumpIt is designed and manufactured based on the IS single-stage centrifugal water pump and ISG pipeline centrifugal pump;

Due to the direct connection between the motor and the pump, the DFW pump simplifies the structure of the intermediate transmission, enhances the smoothness of operation, and reduces the footprint by 30% compared to ordinary horizontal pumps. It also has the advantages of low noise, easy maintenance, and low vibration.

Product Usage

1. Suitable for industrial, urban water supply, and high-rise building water supply

2. Fire pipeline pressurization:

3. Cold and hot water circulation in air conditioning systems

4. Long distance water delivery

5. The production process involves cyclic pressurization and conveying, and is suitable for supporting various water supply and drainage equipment, boilers, and other equipment

DFWTechnical parameters of centrifugal pump

Flow range: 2~1450m ³/h;

Head range: 5-135m;

Environmental temperature: T ≤ 40 ℃;

Pump system working pressure: ≤ 1.6MPa;

When the import pressure exceeds 0.8MPa, the material of the pump body and pump cover must be changed, such as ductile iron QT450-10.

Motor protection level: IP54 or IP55;

Motor insulation level: Class B or Class F;

Medium temperature: -15 ℃<T ≤+80 ℃, hot water type is 80<T<105 ℃, special orders are required for temperatures equal to or higher than 105 ℃.

Mechanical seals can be made of different materials and have reliable sealing performance. Adopting rubber bellows sealing type can prevent sealing caused by shaft corrosion

Failure issue. Special protective measures are taken at the contact between the shaft seal and the shaft to ensure that rust will not affect the sealing of the empty space; The DFW pump is directly connected to the motor, simplifying the intermediate transmission structure.
