GDL (GDLF) series multi-stage pipeline centrifugal pump is a new generation of products designed and manufactured according to JB / TQ6435-92 standard based on excellent pump type at home and abroad combined with user requirements. This series of pumps with vertical segment plus stainless steel shell structure, making the import and export of the pump in the same horizontal line and the same caliber, the same as the valve can be installed in the pipeline, it also focused on the multi-stage pump high pressure, legislation The small footprint of the pump and the advantages of easy installation of the pump. Due to the excellent hydraulic model, it also has the advantages of high efficiency and energy saving, stable operation, etc., and the shaft seal adopts the wear-resistant mechanical seal, no leakage and long service life. GDL pump for high-pressure operating system in the transport of water or physical and chemical properties of the liquid, such as high-rise building water supply, boiler feed water, fire control systems such as transmission or pipeline pressurization purposes. GDLF pump is made of stainless steel (ZG1Cr18Ni9Ti) material, suitable for chemical, food, brewing, pharmaceutical, textile and other industries. According to user requirements can be customized stainless steel 306 or 316L material. Second, the model meaning 80GDL (F) 36-12 × 5 80-pump import and export diameter (mm) GDL --- vertical multi-stage pipeline pump F --- that the overall stainless steel 36 --- Design Point Flow (m 3 / h) 12 --- single-stage head (m) 5 ---- grade 5 Third, the performance range Head: 18.4-270m Flow: 18-155m 3 / h Fourth, working conditions a) The pump can transport clean water or physical and chemical properties similar to clear liquid; b) Temperature range: -15 ℃ ~ +120 ℃; c) working pressure : the maximum pressure of 2.5MPa, that is, the system pressure = inlet pressure + valve working pressure <2.5MPa; d) the ambient temperature should be below 40 ℃, the relative humidity does not exceed 95%; e) When transporting corrosive medium and hot liquid, please put forward when ordering, so that special materials can be used to meet the requirements.
