Product Overview

The IHG vertical pipeline chemical pump is a new-generation vertical chemical centrifugal pump designed and manufactured in accordance with the international standard ISO 2858, using advanced hydraulic models and selecting performance parameters from the IS-type centrifugal pump. It boasts advantages such as high efficiency, energy savings, low noise, zero leakage, and ease of installation and operation. Depending on the operating temperature and medium, it gives rise to a series of products—including IRG, IHG, and YG—that are suitable for hot water, corrosive media, and petrochemical products.
 IHG Vertical Pipeline Chemical Pump

For IHG-type pipeline chemical pumps with motor power exceeding 30 kW, two structural designs are available: direct-coupled and disassemblable. The disassemblable design allows the pump rotor to be removed without moving the motor or pump body, significantly reducing maintenance costs and labor intensity.

Operating Conditions and Application Scope of IHG Vertical Pipeline Chemical Pumps

  1. The suction pressure shall be ≤1.0 MPa, or the maximum working pressure of the pump system shall be ≤1.6 MPa—i.e., the suction inlet pressure plus the pump head shall not exceed 1.6 MPa. The static test pressure for the pump shall be ≤2.5 MPa. Please specify the system’s working pressure when placing your order. If the pump system’s working pressure exceeds 1.6 MPa, this should be explicitly stated at the time of ordering so that the pump’s flow passages and connecting parts can be made of cast steel during manufacturing.

  2. Ambient temperature < 40℃, relative humidity < 40%.

  3. The volume content of solid particles in the conveyed medium shall not exceed 0.1 per unit volume, and the particle size shall be less than 0.2 mm.

  Scope of application:

  1. Suitable for industrial and municipal water supply and drainage, pressurized water delivery in high-rise buildings, landscape irrigation, fire-fighting boosting, long-distance water transportation, HVAC and refrigeration circulation, cold and hot water circulation boosting in bathrooms, and equipment配套. Operating temperature: T < 80℃.

  2. Suitable for boosting and circulating high-temperature hot water in boilers used in metallurgy, chemical industry, textiles, wood processing, papermaking, as well as in hotels, bathhouses, guesthouses, and other similar facilities; also suitable for heating circulation in urban residential buildings. Operating temperature: below 120℃.

  3. Widely used for boosting and circulating high-temperature hot water in boilers in industries such as energy, metallurgy, chemical engineering, textiles, papermaking, as well as in hotels, bathrooms, and guesthouses; also suitable for circulating heating systems in urban residential buildings. Operating temperature: below 240℃.

  4. Suitable for use in industries such as petroleum, chemical engineering, metallurgy, power generation, papermaking, food and pharmaceuticals, and synthetic fibers, with an operating temperature range of -20℃ to 120℃.

  5. Suitable for conveying flammable chemical liquids.

 

Product Features of IHG Vertical Pipeline Chemical Pumps

  1. The IHG chemical centrifugal pump features a vertical design with identical inlet and outlet diameters aligned on the same centerline, allowing it to be installed in pipelines just like a valve. It boasts a compact and aesthetically pleasing appearance, occupies a small footprint, and requires low capital investment for construction. With the addition of a protective cover, it can even be used outdoors.

  2. The impeller is directly mounted on the motor’s extended shaft, resulting in a short axial dimension and a compact structure. The pump and motor bearings are arranged reasonably, effectively balancing the radial and axial loads generated during pump operation, thereby ensuring smooth pump operation with very low vibration and noise levels.

  3. The shaft seal employs either a mechanical seal or a mechanical seal combination, featuring imported titanium alloy sealing rings, medium-sized high-temperature-resistant mechanical seals, and seals made from hard alloy materials that offer excellent wear resistance, thereby effectively extending the service life of the mechanical seal.

  4. Easy to install and maintain—no need to disassemble the piping system; simply remove the pump coupling base nut to extract the entire rotor assembly.

  5. IHG pipeline chemical pumps can be operated in series or parallel configurations according to usage requirements, specifically based on the desired flow rate and head.

  6. The IHG pipeline chemical pump can be installed either vertically or horizontally, depending on the requirements of the piping layout.

  7. Scope of the complete set: The pump, motor, baseplate, coupling, and inlet/outlet short pipes are supplied as a complete set.

Q

What is your typical delivery time?

A

Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。

Q

Do you have centrifugal pumps in stock?

A

Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.

Q

What information should I provide when requesting a quote?

A

Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.

If you are not sure, don't worry, our business managers will assist you in determining this.

Q

What products do you mainly produce?

A

Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.

Q

Could you help me with the selection?

A

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Q

Why is it so slow to get a price quote?

A

Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
