Product overview
GDL type vertical multistage pipeline centrifugal pump is a new generation product designed and manufactured by our company on the basis of better pump types abroad, combined with the user's requirements and fire related standards, and according to JB / tq6435-92 standard.
The suction and discharge ports of the water pump are in the same straight line. The rotor component is composed of shaft, impeller, impeller baffle sleeve, shaft sleeve and other parts. The water inlet section, middle section and outlet section are connected with tension bolts. The shaft seal adopts mechanical seal, lubricated and cooled by pressure water from balance chamber. It is the best pump type for conveying cold and hot water or similar physical and chemical properties to water and other liquids in various industries.
The company has strong technical force, rich production experience and perfect detection means, so as to ensure the stability and reliability of product quality.
Product features
