pump impeller brass

1. What is Credo IS/IR/IY pump ?

1) Type IS pump is single stage single suction (axial suction) centrifugal pump, deliver clean water or other liquid which chemical& physical feature is similar with clean water, the temperature is less than 80 °C. Inlet pressure is less than 0.6Mpa, it is suitable for delivering water in industry, city and farm irrigation.

 2) Type IR pump is heat centrifugal pump, the serial pump design reasonable, in stalling& repairing conveniently, it suitable for delivery clean water or which chemical & physical feature is similar with clean water. Inlet pressure is less than 0.6Mpa, the temperature is no more than 130 °C. It can be 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.

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

3.What is the construction of Credo IS/IR/IY pump  ?

Type IS/IR/IY pump is designed according to National Standard ISO2858. Main parts are pump casing, pump cover, impeller, shaft, sealing parts and cantilever parts etc.

1) Type IS is designed at full back pullout, the pump casing and pump cover is saparate 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 is small, the impeller rear back hasn't wearing and balance holes.

2) Type IR pump have ssame construction type with IS pump, pump cover and sealing hose are combined a cooling house, used for cooling packing and shaft, and prevent heat sending to bearing.

3)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 ssupport pump shaft, and bear pump axial force and radial force.

4) Seal: IS pump is adopted packing seal, in seal, shaft sleeve is installed to protect shaft; mechanical seal can be used according to user srequirement. IR pump seal have two type: packing seal and mechanical seal, icin pump cover have water sealing hole, outer s water sealingbg hole and cooling house. IY pump iss adopted mechanical seal; packing seal can be used according to user requirement.

4. What are the types of sealing and cooling ?

(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
