D、DG Multistage Pump
Product Description
This series of multistage booster pump has a sub-horizontal, multi-stage, single-suction, and centrifugal flow design, and employs state-recommended hydro module technology. This multistage pump is composed of four parts, including the stator, rotor, bearing, and shaft seal. Here, we will discuss each part in detail.
- The stator is comprised of the suction section, the middle section, the discharge section, and the guide vanes. Each section is clamped by a tightening bolt to form a working room. D-type pumps generally suck horizontally and spit upwards vertically; when used for oilfield water injection, the pump inlets and outlets are oriented vertically and upwards. The outlet and inlet of the DG multistage pump are also oriented vertically and upward.
- The rotor is composed of the shaft, impeller, balance disk, and shaft sleeve. The axial force is balanced by a balance disc.
- The multistage pump bearings are composed of bearing bodies, bearings, and bearing glands. The bearings are lubricated with grease or thin oil.
- The shaft seal employs a soft packing seal, composed of a sealed box, packing, and water retaining ring on the water inlet section and the tail cover. The D-type model water seal water comes from the pressure of the water in the pump; the DG model water seal water comes from an external water supply.
- The multistage pump is driven directly by the prime mover through the elastic coupling. Looking at the pump from the end of the prime mover, the pump rotates clockwise. The D and DG models are horizontal, single-suction, multistage, segmented centrifugal pumps.
Product Features
Main Application
- The unique structure and attractive appearance
- Rust-resistant, fully sealed shaft structure, preventing contact with mediums
- Packing seal and mechanical seals are safe, reliable, simply designed, and convenient to maintain
- Low noise
- Advanced hydraulic model, high efficiency, wide performance range
- Suitable for transporting clean water (impurity content of less than 1%; the granularity of less than 0. 1mm) and/or other liquids with similar physical and chemical properties.
- The D/DG multistage pump model is suitable for transportation of mediums with temperatures no greater than 80˚C, including mine discharge and water feeding to factories and cities.
- The D/DG multistage pump is suitable for transportation of mediums with temperatures no greater than 105˚C, water being fed to a small boiler, or similar applications.
- Oilfield water injection pumps use different materials, depending on the corrosive nature of the medium. The temperature of the DG pump must be less than 120 ˚C, which is suitable for various boiler feed water.
