1 CLDF stainless steel multi-stage pumps introduce CDLF stainless steel multi-stage pump with small size, light weight, high efficiency, energy saving, low noise and smooth operation, long life, vertical installation, small footprint, light weight and beautiful appearance notable features, is the ideal replacement products. 2 Features 1, CLDF stainless steel multi-stage pump for the vertical structure, with a small footprint features, pump pump foot center coincides with the center of gravity, thus smooth running, small vibration, long life. 2, the pump of the same caliber and the center line at the same level, without changing the pipeline structure, can be directly installed in any part of their pipes, the installation is very easy. 3, the motor plus rain cover can be placed directly outdoor use, and without the construction of pumping stations, significant savings in capital investment. 4, the pump head can be meet different requirements by changing the pump stages (impellers number), so for a wide range. 5, seal with carbide mechanical seal, reliable seal, no leakage, no mechanical losses. 6, energy efficient, beautiful appearance. 7, injection molded castings more than 50 caliber. 3 uses CDLF stainless steel multi-stage centrifugal especially suitable for boiler feed water, it can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, irrigation, fire booster, water washing, food, brewing, pharmaceutical, chemical, aquatic farming, environmental protection, chemical processes and tools supporting other industries, as the water supply and drainage of the power plant. 4 Conditions 1, used to transport water or physical and chemical properties similar to liquid water; 2, transmission fluid should be no solid particles, no fiber, no strong corrosive, non-explosive; 3, the maximum liquid temperature does not exceed 120 ℃ ; 4, the maximum working pressure does not exceed 2.5MPa; 5, the power supply for 3-phase 380V, 50HZ. Voltage fluctuations within ± 5%; 6, the ambient temperature should be below 40 ℃, relative humidity less than 95%. Installation Instructions 1. When installing piping weight does not bear on the pump, or fragile ring pumps; 2, Joseph pump motor is an integral structure, factory by factory calibration, so no adjustment during installation, and therefore very easy to install ; 3, installation of pumps should be carefully checked before the pump runner whether the impact of a hard object pump operation, (such as rocks, iron ore, etc.) so as not to damage the pump runtime also flow components; 4, the installation must be tightened into the bolt, and each time interval of one fact respond pumped through the line checking to prevent it from loosening, so as to avoid excessive vibration occurs when pump start to affect performance; 5, in order to facilitate the maintenance and use of safe, import and export pipeline pump installation of a control valve and Importers pump installed in the vicinity of a pressure gauge, for high-lift, in order to prevent water hammer, but also in front of the outlet of a check valve installed to cope with a sudden loss of power outages and other power accident, the pump in order to ensure optimum working conditions run, increase pump life; 6, there are suction pumps for the occasion, it should be equipped with a foot valve and inlet pipeline should not have too many corners, but may not have leaks, air leaks, so as not to affect the pump suction performance; 7, in order not to impurities entering the pump and block the flow path affect performance, the filter should be installed in front of the pump inlet; 8, before installation of the pipes to rotate the pump rotor parts, there should be no friction sound or stuck phenomenon, otherwise The reason should check the pump apart.
