Product Description Product DescriptionIH end-suction pump is single-stage single-suction (axial suction) cantilever centrifugal pumps, conveying corrosive liquid with viscosity similar to water without solid particles. Mark, rated performance and size in accordance with international standards ISO2858, with characteristics of a wide range of performance, high efficiency and easy maintenance, the efficiency of an average 5 percent up compared with F-type pump, is the international promotion of energy-saving products.The transmission medium temperature of IH chemical pump is -20 oC ~ 105 oC, can transport medium with a higher temperature with better cooling measurement if necessary , suitable for chemical, petroleum, metallurgy, electric power, paper, food, pharmaceutical and synthetic fiber industries, for transport all kinds of corrosive media similar to water without pollution.Main design featuresSuitable for high-pressure applications with flanges in PN 10 and PN 16"Back pull-out" design makes it possible to remove hydraulic parts without having to remove the pump body from the plant pipesDynamically balanced closed impeller to minimize radial loads and provide smooth rotation of impellerSuction profile designed to reduce NPSH for trouble-free operation in demanding conditionsStainless steel shaft designed to withstand the bending-torsion loadOversized ball bearings provide reduced working noise and a long service lifeLarge selection of mechanical seals or gland packings (SES) configured according to the requirements of the fluid characteristics and conditions of use Pump Speed1450 and 2950rpm;Motor Voltage380V/415V, 3.3KV, 6KV and 10KV;Caliber50-400mm;(flange dimensions conform GB/T17241.6-1998)Flow range6-1000m3 / hrHead range6-130m;Temperature rangeMedium maximum temperature ≤170'C, ambient temperature ≤60'C;Maximum operating pressure (inlet pressure + pump pressure)1.0Mpa (G) (Hsp75m) or 1.6Mpa (G) (Hsp75m);Special configuration of up to 2.5Mpa (G);Transmission mediumWater or other liquids physical and chemical properties similar to water;Seal plumbing partsNo installment when inlet pressure above 0.03Mpa (G)Structural Design29 basic types, of which 22 pairs speed (1450rpm, 2900rpm) through A, B with two forms of the impeller diameter cutting variants, reaching 112 specifications.Detailed Photos In order to balance axial thrust, there are both wear rings in front and at the back of the majority of the impeller and the balance hole is on the back shroud of the impeller. The axial thrust of some pumps is not big enough, so there is no wear ring and balance hole at the back of the impeller.High-precision casting impeller can ensure the performance, material in cast iron, stainless steel and bronze. Packing pump cover is equipped with stuffing, for soft packing seal, the stuffing may pass into a certain pressure of water for seal cooling, lubrication, cleaning;Single mechanical seal and double mechanical seal two species for mechanical seal, a certain pressure into the seal cavity through the water, rinse the end surface friction, while cooling effect. According to demand while allowing the use of a sealed cavity adapted to form a predetermined size of ISO3069 other structures, such as mechanical seal with corrugated pipe and expeller seal. Flexible couplingsUnlike rigid couplings, flexible couplings can accommodate some movement e.g. vibrations and thermal expansion without damage. This makes them ideal for applications where there is a degree of unavoidable misalignment between the drive and pump shafts. As they can absorb vibrations well, they can also be used to reduce excessive operating noise. With these benefits come a more complex, expensive design. However, as flexible couplings protect the shaft and bearings from damage and premature wear, there are maintenance savings to be had in the long run.We use wear-resisting disc coupling or pin coupling. Product ApplicationThis product is widely used in urban water supply and drainage, urban water supply, central heating systems and drainage, iron and steel metallurgy companies, oil refineries, paper mills, oil, power plant, airport construction, chemical plants, textile mills, sugar mills, chemical plants, power plants and drainage, plant mines consumer drainage systems, air conditioning systems of water supply, agricultural irrigation, drainage and various water projects. Facilities & Equipments Professional cooperation agencies This company has established long-term cooperation relationship with a number of large domestic pump-testing institutions, such as: National Quality Supervision and Inspection Center of Industrial Pumps (Tiexi District,Shengyang city), Irrigation Machinery Products Quality Inspection Center of Machinery Industrial (Zhenjiang City), Ministry of Agriculture, Water Pump Quality Supervision and Testing Center (Chongqing city), Shanghai Mechanical and Electrical Products Quality Inspection Center (Shanghai city) and so on.
