Product Overview IS IS Pump water pump, IR horizontal single-stage single-suction centrifugal pump water, is the joint design of energy-efficient pump, which is a type BA, BL-type and other single-stage centrifugal pump water newer. Benefits include: a full range of hydraulic performance, reasonable layout, user selected range, easy maintenance; efficiency and suction lift up to international advanced level on average. This pump is suitable for industrial and urban water supply, drainage, can also be used for agricultural irrigation and for conveying water or physical and chemical properties similar to water or other liquids, the temperature is not high 80 ℃. IS Pump Product Features 1, IS, IR horizontal single-stage single-suction centrifugal pump water according to ISO2858 international standard of performance required and the size of the design, mainly by the pump, pump cover, impeller, shaft, seal rings, bushings and suspension bearings and other components missing. 2, IS, IR horizontal single-stage single-suction centrifugal pump and water pump cover part of the split at the back of the impeller, which is usually said rear door structure. The advantage is easy maintenance, overhaul does not move the pump, suction line and discharge piping and electric motors, simply remove the spacer coupling intermediate couplings, can exit the rotor section for maintenance. 3, the pump casing (ie, pump and pump cover) constitute pump studio. Impeller, the pump shaft and the rolling bearing of the rotor. The suspension member support bearing rotor portion of the pump, the pump bearing by radial and axial forces. 4, in order to balance the axial force of the pump, the majority of pump impeller before and after the sealing ring has, and a rear panel of the impeller balance holes, not because some force pump, the impeller is not set back seal rings and balance holes. 5, the pump axial sealing ring is made of packing gland, packing rings and packing, etc., in order to prevent the intake or a large leak. If pump impeller balancing, with soft packing cavity communicates with the impeller inlet, such as the impeller inlet liquid in a vacuum, it is very easy along the surface of the inlet sleeve, so the packing with packing ring cavity through pump cover holes, will lead to pump the water pressure in the chamber is sealed packing rings. The pump impeller if there is no balance hole, because the back of the impeller fluid pressure greater than atmospheric pressure, and thus there is no leakage problem, it is time to install the packing rings.
