Key points for selecting fluoroplastic centrifugal pumps for transporting oxidized water (pH=2 with sand)

2025-06-20

This article analyzes the available pump types for specific media to help you make a faster and more effective selection, and also provides some data for your reference.

1.Working condition characteristics analysis

Medium characteristics

Strong acidity: pH=2 is a strong acid environment, and the acid corrosion resistance of the material needs to be considered

Oxidation: The medium has oxidizing properties, and the material's antioxidant capacity needs to be evaluated

Containing solid particles: The presence of small sand particles will cause wear problems (it is recommended to confirm the particle size distribution and concentration)

2.Material selection

2.1 It is recommended to use PTFE (polytetrafluoroethylene) or F46 lined pump body, which has the following features:

✓ Strong acid resistance (applicable to the full range of pH 0-14)

✓ Excellent oxidation resistance

✓ Smooth surface and not easy to scale

2.2 Mechanical seals are recommended to use SiC/SiC pairing, which is more resistant to particle wear than graphite

2.3 Key selection parameters

Required notes Speed ≤ 2900rpm: reduce particle erosion and wear

Impeller type semi-open/open impeller: avoid blockage of closed impeller flow channel

Gap design is 0.3-0.5mm larger than standard pump to accommodate particle passage

Shaft seal type: double-end mechanical seal + flushing water (Plan53B external flushing solution is recommended)

3. Special design points

Wear-resistant structure

The impeller front cover is thickened by 2-3mm

A replaceable wear-resistant plate is set at the volute of the pump body

The surface of the flow-through parts can be hardened

4. Operation suggestions

It is recommended to install a Y-type filter at the inlet (the mesh size is determined by the particle size)

The minimum flow rate should be >30% Qn to prevent solid deposition

The flow channel should be flushed in time when the machine is shut down

5. Recommended typical models

Domestic: IHF80-65-160 fluoroplastic centrifugal pump (with wear-resistant modification kit)

Imported: CPK80-200F (with impeller for granular media)

If the budget is li mited, you can consider: FSB80-50-200 (need to confirm the actual particle parameters)

If you have better ideas, please leave a message. We are happy to learn new knowledge and provide better service.

Air cooled screw chiller an efficient and energy-saving cooling solution

2025-06-20

With the continuous development of industrial production, the demand for cooling equipment is also increasing. As an efficient and energy-saving cooling solution, air cooled screw chillers have been widely used and recognized.

The air cooled screw chiller uses advanced air-cooling technology to quickly and effectively discharge the generated heat through cold water circulation and fan heat dissipation, thereby achieving cooling purposes. Compared with traditional water cooling methods, air-cooled screw chillers have the following significant advantages.

First of all, air cooled screw chillers perform well in terms of energy saving. The traditional water cooling method requires additional cooling water systems and water pumps for circulation, which not only consumes energy, but also requires a lot of maintenance and management. The air-cooled screw chiller dissipates heat through fans and does not require an additional water cooling system, which greatly reduces energy consumption and operating costs, achieving high efficiency and energy saving.

Secondly, air cooled screw chillers have a smaller footprint. The traditional water cooling system requires the establishment of a special computer room and the installation of water pumps, cooling towers and other equipment, which takes up a lot of space resources. The air-cooled screw chiller has a compact structure and can be placed directly next to the production line or in the corner of the factory, saving valuable space and improving production efficiency.

In addition, the air cooled screw chiller has good flexibility and stability. It can be adjusted according to production needs to achieve matching cooling capacity. At the same time, the air-cooled screw chiller uses reliable screw compressor technology, which has a low failure rate and stable operation. This means that it can maintain a stable cooling effect under various working conditions and ensure continuous production.

After the above summary, it can be seen that air cooled screw chiller, as an efficient and energy-saving cooling solution, has become the first choice of many enterprises. It can not only meet the needs of industrial production for cooling equipment, but also save energy, reduce floor space, improve production efficiency, and contribute to the sustainable development of enterprises. As a supplier of air cooled screw chillers, we aim to provide the best services to more companies.

How to chose a water chiller system for your stretch film machine and film blowing machine

2025-06-20

In the process of producing stretch film, the cooling system is very important, which directly affects the quality and output of stretch film. In general, we recommend choosing a chiller model with a cooling capacity slightly larger than the flow rate required for cooling, so as to ensure that the temperature and water flow rate can be kept within the required range under long-term stable operation.

When choosing a water chiller system for your stretch film machine and film blowing machine, there are several factors to consider:

Cooling Capacity: Determine the cooling capacity required for your machines based on their heat load. Consider factors such as the machine size, material type, production rate, and ambient temperature.

Temperature Control: Assess the temperature control requirements of your machines. Depending on the application, you may need precise temperature control to achieve optimal production conditions.

Chiller Type: Select a chiller type that suits your specific needs. Water-cooled chillers offer more efficient cooling but require a water source, while air-cooled chillers are easier to install and maintain but may be less efficient in certain environments. Oumal Chiller will provide professional suggestion of water cooling system for your stretch film machine. Below is the picture of our air cooled screw chiller in a plastic factory cooling the film stretch machine.

Industrial air chiller vs industrial glycol chiller Choose the cooling solution that’s right for you

2025-06-20

The cooling demand in the industrial field is growing day by day. Industrial water chillers and industrial glycol chillers are two common cooling devices. Although they can both effectively reduce the temperature, there are some differences in function and applicability.

Industrial water chiller is a cooling device that uses a fan to cool air through a radiator. It reduces the temperature of the cooling medium through a compression refrigeration cycle, and then dissipates the cooling medium through the fan of the radiator to remove the heat from the system. This type of chiller has the characteristics of small size, easy maintenance and simple installation. It is suitable for small power cooling needs in some industrial environments, such as computer rooms, laboratories, small processing equipment, etc.

4Ton Industrial Water Chiller

Industrial glycol chillers use ethylene glycol as the cooling medium, and send ethylene glycol to the cooling equipment for cooling through a circulating pump. Ethylene glycol has good low-temperature performance and thermal stability, can provide stable cooling effect at lower temperatures, and is suitable for some industrial production scenarios with high temperature requirements, such as chemical, pharmaceutical, semiconductor manufacturing, etc. Glycol chillers are usually larger in size and require relatively complex piping systems for transportation and installation, but they can provide more stable and precise temperature control.

So the choice between industrial water chillers and industrial glycol chillers should be based on specific needs. If your cooling needs are small and the temperature control requirements are not high, industrial water chillers are an economical and practical choice.

If you need precise cooling at lower temperatures and have strict requirements for temperature control, then industrial glycol chillers will be a more suitable choice. If you want to understand cooling solutions, you can choose oumalchiller reliable supplier and high-quality equipment.
