Product Overview
GDL multi-stage pipeline centrifugal pump is a new generation product designed and manufactured according to JB/TQ6435-92 standard based on the excellent pump type of our company and the user's use requirements and fire-related standards. The vertical segment type plus stainless steel shell structure makes the inlet and outlet of the pump on the same horizontal line and the same diameter. It can be installed in the pipeline like a valve. It also concentrates the high pressure of the multistage pump. The advantage is that the footprint is small and the installation of the pipeline pump is convenient. It has the advantages of high efficiency, energy saving, stable operation, and the shaft seal adopts wear-resistant mechanical seal, and has no leakage and long service life.
 
Product Features
It has the advantages of high efficiency, energy saving, stable operation, and the shaft seal adopts wear-resistant mechanical seal, the use temperature &100; C, working pressure ≤ 1.6MPa (16kg / cm3). Flow rate: 5-300m3/h Head: 5-250m speed 2900r/min
 
Product usage
The GDL pump is suitable for conveying clean water or physicochemical liquids in high-pressure operation systems, such as high-rise building water supply, boiler feed water, fire protection systems, etc. The GDLF pump is made of monolithic stainless steel (ZG1Cr18Ni9Ti) and is suitable for chemical, food, brewing, pharmaceutical, textile and other industries. Stainless steel 304 or 316L material can be customized according to user requirements.
