IS end-suction water 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 IS end-suction water pump is -20 ℃ ~ 105 ℃, 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.
Flow capacity 6.3 ~ 400m3/hr;
Head 5 ~ 125m;
Speed 1450rpm and 2900rpm;
Required power 0.55 ~ 90kw;

IH chemical pump has 29 basic types, of which 22 pairs speed (1450rpm, 2900rpm) through A, B with two forms of the impeller diameter cutting variants, reaching 112 specifications.
IS type end-suction pump is jointly designed product by the whole domestic industry through adopting the international standard ISO, which are mainly composed of the pump body, impeller, seal rings, impeller nuts, pump cover, sealing parts, the middle frame, axle, suspension components.
Structural characteristics of the pump: pump cover fixed in the middle bracket by the seam allowance and clamp pump cover in the middle by the connection of middle bracket spigot pump case. Pump case is an axial suction and radial discharge, foot support type, can be directly fixed onto the base. Suspension department is fixed on the intermediate frame by the seam allowance, and supported on a base with a suspension bracket. To facilitate the demolition, design lengthened coupling, without disassembling overhaul inlet and outlet connection piping, pump and motor, just remove the intermediate connector couplings longer, you can remove the rotor parts for maintenance, which is a common international structure.
The direction of rotation of the pump: The pump is directly driven by the coupling by lengthening the motor, clockwise from the motor end.
Pump shaft seal: mechanical seal and packing seal in the form of pump seal. 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.
