IH Chemical Pump  General Description

IH series pump is a single suction and single stage cantilever centrifugal one for chemical industry use, which adopts an international standard, being in conformity with the standards in ISO2858、ISO3069、ISO3661. This product is confirmed by the Mechanical Industry Department of the state to take place F type corrosion – resisting centrifugal pump (above 50 diameter)for it is an energy – saving novel product. Its efficiency is 3～5% higher than F type pump, the cavitation residual volume is superior and sucking function is fine, which is suitable to convey the liquid with erosion, being able to apply on the departments of chemical industry, petroleum, metallurgical industry, paper making, food, pharmaceutical industry and compound fabric industry etc.

IH Chemical Pump  Feathers of Structure

The pump consist of pump casing, impeller, sealing ring, pump cover, shaft and bearing house etc. The pump adopts a structure of rear-door, for facilitating maintenance without dismantling pipe system of inlet and outlet. Much convenience in application.

The pump casing is designed with feet below, and discharge is positioned upward, suction in the axial.

The size of the pump flange adopts GB9113.3-88（1.6MPa），equivalent to HG20595-97（1.6MPa）.

Rotor part is supported by rolling bearings, the bearing uses N32 machine oil for lubrication, if you want to use grease for lubrication, please make a note in the ordering.

The impeller nuts adopt steel spacer for preventing loose, which can effectively prevent loose and misplace of the impeller nuts due to the vibration in the operation and reverse rotation.

Oil meter adopts automatic making-up type, so to guarantee the lubrication during operation, thus raising up the lifetime of the pump.

Viewing from the end of driver, the rotation direction of the pump is in clockwise.

The material of parts which contact with liquid are made by 1Cr18Ni9、1Cr18Ni9Ti、1Cr18Ni12Mo2Ti、304、304L、316、316L、904、alloy 20#、CD4MCu、Hastelloy alloy etc. we can also adopt the other corrosion-resistance materials according to user’ s requirement.

IH Chemical Pump   Shaft Sealing

The shaft sealing adopt with stuffing sealing, single mechanical sealing, or double –end mechanical sealing. In case that the pump suction pressure is bigger, it is advised to select balance mechanical sealing.

The stuffing sealing is used in the case that the requirement for site in clearance is not strict and a little leakage is permissible. Or in case that the liquid conveyed is easily crystallized or contained with grain, it is also advised to use stuffing sealing.

The mechanical sealing is characterized by the function reliable, leakage less and life time longer. It divides single mechanical sealing and double mechanical sealing. In which the double mechanical sealing is suitable to apply on the occasions in high temperature, being flammable, easily blasting, and easily volatilizing poisonous agent and with strong erosion, with suspending particles, easily crystallized and with fabric agent.

There sets up an automatic flush device in the inside of single mechanical sealing. Whereas the double mechanical sealing needs connecting with the outside for flush liquid, which is various in degree due to the difference in pumping liquid, temperature and pressure etc. working conditions. The flush liquid takes clear water or medium pumped. In case that the temperature of the agent is high or contained with grain, it should conduct

cooling proceed to the agent first, after filtering then getting through into sealing cavity.

The pressure of washing liquid should be 0.05～0.1MPa higher than the pressure in the front of sealing cavity. Before starting the pump, it needs to open washing and cooling system at first, and not to cut off that system before stopping operation.

Flush liquid pressure: Pump suction pressure + Head×45%

(Maximum not above 0.8MPa for unbalance mechanical sealing)
