multistage water pump OUTLINE Model GDL multi-stage pipeline centrifugal pump is a new generation product designed and made by this Co, on the basis of the excellent pump types both domestic and overseas and combining the requirements of use and the related fire-fighting standards and following the standard of JB/TQ 6435-92. This pump uses a vertical, sectional and stainless steel casing structure to have both inlet and outlet on a same level, of a same aperture and capable of being mounted in a pipeline just as a valve and collects the merits of the high pressure of a multi-stage pump, a less land area of a vertical pump and convenient installation of a pipeline pump and, due to the excellent hydraulic model it adopts, also features a high efficiency, energy-saving, stable running etc., in addition, because of the wearable mechanical seal it uses as the shaft seal, it has no leak and a long duration of use. To provide a better satisfaction to the requirements of users, this Co. also develops model GDL the outlet of which is located on the upper part and both inlet and outlet can be mounted in different opposite positions (0°, 90°, 180°), leaving an extremely convenient use. RANGE OF APPLICATION Mainly used for the circulation and boost of both cold and hot pure waters in a high pressure moving system, water supply with pumps in parallel in a high building, the water supply and cooling water system of fire-fighting and boilers and the transporting of various rinsing liquids. WORKING CONDITIONS 1. This pump can transport pure water and the liquid the natures of both physics and chemistry of which are similar to those of pure water. 2. Liquid temperature: -15+120. 3. Working pressure: maximum one2.5MPa, i.e. the system pressure+ the pressure at work with valve closed2.5MPa. 4. The ambient temperature should be below 40, RH no more than 95%. 5. Please make a note at order if the pump is used to transport corrosive media and hot liquid so as for us special materials to meet with the demand.
