HJ series chemical centrifugal pump

Overview

The HJ and IJ single-stage single suction cantilever chemical centrifugal pumps are new products optimized and designed based on the IH series pumps and with reference to foreign new technologies. Their rated performance and installation dimensions comply with the 1SO2858 standard, and their manufacturing technical conditions comply with the ISO5199 standard. They are mainly suitable for transporting slurries with solid content less than 50% in chemical processes.

Compared with IH pumps, HJ and IJ chemical pumps have the following structural characteristics:

1. Fully open impeller;

2. Shortened the cantilever of the impeller and increased the diameter of the shaft;

3. Asymmetric cross-section volute and pump casing without mouth rings;

4. The impeller nut is integrated with the impeller;

5. Equipped with a new type of seal similar to advanced foreign double end mechanical seals or packing seals.

Due to the above structure, the pump has the following advantages:

1. It can transport high viscosity or solid containing media, and the efficiency of the pump is higher than that of the IH pump;

2. Asymmetric cross-section snail shell reduces fluid impact loss and shortens pump casing size;

3. Increasing the strength of the shaft reduces the deflection of the rotor, resulting in stable operation and long sealing life;

4. The impeller nut is integrated with the impeller, improving the inlet conditions of the pump and enhancing its anti cavitation performance;

5. Advanced shaft seal form ensures better sealing effect and reduces pump leakage;

6. The clearance of the pump can be adjusted without disassembling the pump casing and impeller, reducing maintenance time and saving maintenance costs.
