Product Overview:
GDL type vertical multi-stage pipeline centrifugal pump is a more common vertical multi-stage pipeline centrifugal pump, and the suction and discharge ports of the water pump are located on the same straight line. The rotor parts are composed of shafts, impellers, impeller block sleeves, shaft sleeves and other parts, and the water inlet section, middle section and outlet section are connected by tensioning bolts. The shaft seal adopts a split mechanical seal, which is lubricated and cooled by the pressure water of the balance chamber. It is an ideal pump type for hot and cold water or liquid with physical and chemical properties similar to water (it has been replaced by QDL series pumps in recent years).
Scope of application:
It is widely used in the working conditions of conveying head that cannot be reached by single-stage pumps such as ISG series.
Product Features:
1. Pipeline type, easy to install.
2. The lift range is larger than that of a single-stage pump.
3. The cylinder of the pump body is made of stainless steel and has a beautiful appearance.
4. The shaft seal is a mechanical seal. If the user uses it properly, it will have an ideal service life, and there is no trouble of packing seal leakage.
5. The flow channel has been redesigned, and the hydraulic noise of the operation is not large.
6. Vertical structure, small footprint.
