General Description
    IS series single stage single suction(axial suction) centrifugal end suction pump, deliver clean water or other liquid which chemical & physical feature similar with clean water, the temperature less than 80°C.Inlet pressure less than 0.6MPa, it suitable for delivering water in industry, city and farm irrigation.
    IR series heat centrifugal pump, the serial pump design reasonable, installing & repairing conveniently, it suitable for delivery clean water or which chemical & physical feature similar with clean water. Inlet pressure less than 0.6MPa, the temperature not more than 130°C.n It can equipped with boiler and heat-changer, as circulating water pump or feed pump, also used to supply water, for example, supply water in city and mine etc.   

    IY series single stage single suction centrifugal oil pump, suitable for delivery no corrosive liquids and petroleum products, which not contain solids and the viscosity less than 120Cst. Also used to deliver clean water or other liquid which chemical & physical feature similar with clean water, the temperature less than 80°C.Inlet pressure less than 0.6MPa

Structure

Pump designed according to National Standard ISO2858.Main parts are pump casing, pump cover, impeller, shaft, sealing parts and cantilever parts etc.
Pump designed at full back pullout, the pump casing and pump cover separate from impeller back face, Pump casing and pump cover are combined a working house; impeller, shaft, and rolling bearing are combined a rotor; cantilever support and bearing parts support the rotor. To balance the axial force, impeller rear cover have balance holes, impeller have wearing. If the axial force small, the impeller rear back hasn't wearing and balance holes.
IR pump have same construction type with the IS pump, pump cover and sealing hose are combined a cooling house, used for cooling packing and shaft, and prevent heat sending to bearing.
Bearing: adopt two radial ball bearing, ( IR pump is one set radial ball bearing, two set radial thrust-force ball bearing), installed in cantilever support, to support pump shaft, and bear pump axial force and radial force.
Seal:  IS pump adopted packing seal, in seal, shaft sleeve installed to protect shaft; mechanical seal can be used according to user requirement.
IR Pump seal have two type: packing seal and mechanical seal, in pump cover have water sealing hole, outer water sealing hole and cooling house.
IY pump adopted mechanical seal; packing seal can be used according to user requirement.

Type of sealing and cooling has several kinds as follow: 
(1) packing sealing: itself water sealing without cooling water
(2) packing sealing: itself water sealing with cooling water
(3) packing sealing: outer water sealing without cooling water
(4) packing sealing: outer water sealing with cooling water
(5) mechanical seal: without cooling water
(6) mechanical seal: with cooling water
