IH Chemical Centrifugal Pump

WYT's IH chemical pump stands as a prime example of an advanced chemical centrifugal pump, specifically designed as a single-stage, single-suction cantilevered centrifugal pump. It incorporates a metal casing lined with fluoroplastic, a strategic structural design that significantly boosts its corrosion resistance. The pump cover, impeller, and axle sleeve are meticulously sintered and molded as an integral unit by embedding fluoroplastic with metal inserts. This robust construction ensures the pump's ability to reliably and steadily transport a wide range of strong corrosive media, including sulfuric acid, hydrochloric acid, nitric acid, aqua regia, strong alkalis, strong oxidizing agents, and organic solvents, over extended periods. While distinct from compact 12 volt chemical pump units and precision chemical feed pumps in its specific application and design, the IH chemical pump exemplifies the innovation and reliability expected in high-performance chemical handling solutions.

Application Scenarios

Basic Chemical

Sulfuric acid, nitric acid, hydrochloric acid and other strong acid transportation.

Petrochemicals

Crude oil, solvent, catalyst circulation.

Pharmaceutical and foodstuff

Aseptic media, high-purity drug delivery.

Environmental engineering

Wastewater treatment, exhaust gas scrubbing system.

Product Advantages

Excellent corrosion resistance

The sintering process ensures that the fluoroplastic layer is tightly bonded with the metal substrate without seams or weak points, which significantly improves the overall structural strength, sealing and corrosion resistance.

Efficient sealing performance

Mechanical seal design is tight and reliable, and the material combination of static ring and dynamic ring ensures zero leakage, making it suitable for chemical production environments with very high sealing requirements—a critical feature for any chemical centrifugal pump, including compact 12 volt chemical pump models, and especially advantageous when precise dosing is needed in chemical feed pumps applications.

Direct-coupled horizontal mounting eliminates alignment complexities of diaphragm chemical metering pump systems. This chemical pump deploys leak-free in minutes: connect ANSI flanges, secure baseplate, and start continuous transfer – a critical advantage over maintenance-intensive chemical feed pump alternatives.

1. The reasonable installation of the pump has a significant impact on its normal operation and service life. Therefore, careful calibration must be carried out before installation, and the appearance and installation dimensions of the pump are detailed in Figure 5 and Table 4.

2. It must be ensured that the pump does not exceed its allowable cavitation allowance during operation. The suction height (or backflow height) of the pump must be determined based on the cavitation allowance characteristics of the pump, the resistance loss characteristics of the pipeline, and the suction liquid level pressure of high-temperature water. When using the pump suction, a bottom valve should be installed on the suction pipeline, and a filling screw hole or valve should be set on the outlet pipeline for filling the pump before starting; When using a pump for backflow, valves and filters should be installed on the suction pipeline to prevent debris from entering.

3. The suction and discharge pipelines should have additional brackets and cannot be supported by pumps.

4. The location for installing the pump should be convenient for patrol inspection and maintenance.

5. Installation sequence

(1) Place the unit on a foundation with embedded anchor bolts, and place pairs of wedge pads between the base and the foundation for alignment.

(2) Release the coupling. Place a spirit level on the pump shaft or base respectively, adjust the wedge pad to align the level of the unit, and then tighten the foundation bolts appropriately to prevent movement.

(3) Pour concrete into the base and anchor bolt holes.

(4) After the concrete has dried and solidified, the anchor bolts should be tightened and the levelness of the pump shaft should be rechecked

(5) After connecting the pipeline and determining the direction of motor rotation, connect the coupling and double check the concentricity of the shaft. Measure the difference between the outer circle of the coupling, which should not exceed 0.1mm. The gap between the end faces of the two couplings should not exceed 0.3mm between the maximum and minimum gaps within one week.

(6) After 3-4 hours of actual operation of the unit, a final inspection should be conducted. If there are no defects, the installation is considered qualified.
