Single Stage Horizontal Centrifugal Chemical Process Pumps Stainless Steel 1450RPM-2950RPM

DINKONDA GLOBAL Power Plants Special IH Type Corrosive Chemical Liquid Stainless Steel Single-stage Single Suction Horizontal Chemical Centrifugal Pump

Product Overview
IH type chemical centrifugal pump is a single-stage single suction horizontal chemical centrifugal pump designed according to international standards, belonging to the general process pump in the petrochemical industry. This product uses stainless steel overcurrent components, installed on a horizontal base, and connected to a motor through an elastic coupling. It is specifically designed for transporting various corrosive chemical liquids and is suitable for continuous chemical process transportation scenarios such as chemical, pharmaceutical, metallurgical, and environmental protection.

Structural Composition
1. The whole machine consists of a pump body, stainless steel impeller, pump cover, shaft, mechanical seal components, suspension components, elastic coupling, coupling guard, motor, and common base.

2. Overcurrent components: 304/316L stainless steel material, resistant to acid and alkali corrosion, precision cast;

3. Shaft seal: Single end/double end mechanical seals can be selected to adapt to different media and reduce leakage;

4. Suspension assembly: built-in rolling bearings, stable lubrication, support pump shaft, stable operation;

5. Coupling+Yellow Safety Shield: Elastic coupling provides cushioning and shock absorption, while the shield ensures safe operation of the equipment;

6. Integral cast iron base: Good rigidity, easy to level and install the whole machine.

Core Features
1. Strong corrosion resistance: The overcurrent components are made of stainless steel and can transport various corrosive media such as weak acids, weak bases, salt solutions, etc; Materials can be replaced as needed to adapt to strong corrosion conditions;

2. Standardized design: IH is an internationally recognized chemical pump series with strong component universality and convenient spare parts procurement;

3. Rear door structure: During maintenance, there is no need to disassemble the inlet and outlet pipelines, and the rotor components can be directly extracted, saving time and effort in maintenance;

4. Stable operation: The rotor has undergone precise dynamic balance correction, with low vibration and noise, suitable for long-term continuous 24-hour operation;

5. High hydraulic efficiency, low energy consumption, and stable flow rate;

6. The sealing scheme is flexible and can be equipped with flushing and cooling structures to cope with high temperature and easily crystallizable media.

Metallurgy, printing and dyeing, food: transportation of various corrosive process fluids;
Petroleum and light industry: transportation of light crude oil and various chemical intermediates.

Installation And Usage Precautions
1. The installation of the pump base must be leveled, and the weight of the pipeline cannot be borne by the pump flange. Independent supports should be added to the pipeline;

2. Fill the medium and exhaust the air inside the pump before starting, and strictly prohibit idling to prevent the mechanical seal from burning out;

3. When the medium contains impurities, install a filter in the inlet pipeline to prevent particle wear on the impeller and seal;

4. After the installation of the unit is completed, calibrate the coaxiality of the coupling to avoid vibration and bearing damage caused by eccentricity;

5. Transport crystallization prone media, rinse the pump chamber promptly after shutdown to prevent crystallization from jamming the impeller;

6. Regularly inspect the temperature rise of bearings and mechanical seal leakage, and replace lubricating oil and seals on schedule.
