The IHE type chemical standard pump is an improved type of IH, which is a single-stage single-suction cantilever centrifugal pump. Its marking, performance and dimensions conform to the GB5662-85 "Axial Suction Centrifugal Pump (16bar) Marking, Performance and Dimensions" equivalent to the ISO2858-1984 standard. Manufacturing technical conditions adopt GB5656-94 "Single-stage single-suction chemical centrifugal pump technical conditions" (equivalent to ISO/DIS5199-1986)
This series of pumps are widely used in chemical, fertilizer, metallurgy, electric power, paper, food, pharmaceutical, synthetic fiber and other industrial sectors to transport corrosive or non-contaminating media without solid particles.
Pump delivery medium temperature is generally -20 ° C ~ +150 ° C, special up to +180 ° C.
Compared with the IH pump, the IHE pump shaft is thicker and the reliability is greatly improved.
The rear door structure is adopted, and it is not necessary to disassemble the pump body and the pipeline during maintenance.
Shaft seals are available with packing seals, built-in and exterior-mounted single-end mechanical seals, and double-faced mechanical seals. The mechanical seal is suitable for cleaning media without suspended particles. The newly installed pipeline should be rinsed clean. For the crystallized medium, it should be washed frequently. The sealing surface should be rinsed off after stopping and restarting.
