chemical pump factory

As a chemical pump supplier for over ten years, finding the right solution for your chemical process is critical. Pumps incompatible with your chemicals can cause swelling, dissolution or embrittlement, eventually leading to leaks and failure. This is why special consideration needs to be given to the materials of chemical transfer pumps, as well as the temperature and concentration of the fluids being handled. 

To ensure that the chemical transfer pumps we select will give you a long, trouble-free life, we request complete fluid information to consider the material thoroughly.

What is a chemical pump?

Chemical pumps are needed when moving liquids that cannot be moved with standard pumps. They are typically used when the chemicals to be transferred are corrosive or abrasive. Some industrial fluids commonly used in chemical pumps include acetic acid, sulfuric acid, and sodium hypochlorite.

They are more durable than traditional pumps. It gives you the option to move the fluid in several ways. When purchasing one of these units, it is essential to ensure that you are getting the correct pump for the type of chemical you plan to transfer.

choosing a chemical pump

Different types of chemical pumps play different roles. When choosing a chemical pump, be sure to clarify which field the chemical pump needs to be applied to, and the purpose of the chemical pump. If you have special requirements, you can ask BISON, such as pump casings, impellers, shafts and bushings, couplings, seals, etc. Ensure that the model and performance of the chemical pump meet the requirements of process parameters such as flow, head, pressure, temperature and suction.

Chemical pump specifications

The critical step in purchasing a chemical pump is determining the required performance specifications. Key specifications to consider include the following:

• Flow

• Pressure

• Head

• Horsepower

• Operating temperature

power source

Chemical pumps are powered by many different sources. Depending on the equipment you want, it can be powered by one of many sources: AC or DC voltage, hydraulic or pneumatic systems, diesel, or petrol engines, water, steam and natural gas.

Types of chemical pumps

Air-operated diaphragm pumps

These chemical pumps come in various sizes and specifications, so choosing the one that suits your needs is essential. Diaphragm pumps also include a discharge check valve to help prevent backflow.

Centrifugal pumps

The speed at which centrifugal force is generated makes this pump very effective in transferring extraordinarily corrosive and dangerous chemicals. By utilizing a rotating impeller, they increase velocity and help push fluid through the outlet valve.

Lobe pumps

This positive displacement pump is ideal for pumping thicker products such as creams and oils.

materials of chemical pumps

Different materials are used to make chemical pumps, which give it different properties. For example, some chemical pump materials cannot transport flammable and explosive materials. In addition, the corrosion resistance of different materials is different. For the petrochemical production industry, the corrosion resistance of the pump is particularly important. The material used in the pump mainly considers the strength, rigidity, hardness, plasticity, impact toughness and fatigue resistance of the material.

• Substrates such as cast iron, plastic and stainless steel have different strengths in handling these other properties.

• Plastics and thermoplastics are probably the cheapest base materials and have excellent resistance to acids and various chemicals.

• Stainless steel alloys resist chemical attack and rust and have a higher pressure rating than most plastics.

• Cast iron offers excellent strength and wear resistance with high-pressure ratings.

performance of chemical pumps

Are chemical pumps wear-resistant? How about the heat resistance of chemical pumps? How about the noise produced by chemical pumps? BISON offers many types of chemical pumps, which are corrosion resistant, airtight, long service life, small in size, light in weight, stable in performance and easy to install. It is widely used in petroleum, chemical, metallurgy, synthetic fiber, pharmaceutical, food and other industries, and is specially used to transport alkaline corrosive media.

after-sales service of the chemical pump supplier

BISON has a dedicated after-sales service team and technical team that can quickly solve your chemical pump problems. In addition, we also provide complete chemical pump videos, chemical pump images, and other files to help you understand chemical pumps in more detail.

Applications of chemical pumps

Chemical pumps are used in unloading raw materials, raw material preparation, processing, and conversion processes up to storage and in many other areas, such as wastewater treatment. For example:

• Chemical manufacturing and processing

• Pulp and paper manufacturing

• Cryogenics

• Oil & gas production

• Automotive

• Semiconductors

• Food processing

• Agriculture

Precautions

1. When different chemical solutions are mixed, they will react or even generate heat and damage the pump. Do not use the same pump to pump other chemical solutions.

2. Chemicals may cause serious injury. 

3. Please check the discharge and suction pipes and valves before the operation. Make sure the valves are in the correct position, then start. During the process, the discharge is usually checked.
   

4. Improper handling, such as valve closure, incompatible materials, and dry running, can be hazardous. Especially idling will generate heat and steam, and even some chemicals will decompose hydrogen and explode.
   

5. Start the pump and check the discharge outlet. If it is too low, unplug the pump immediately and check the line for blockage.
   

6. The pump can be equipped with explosion-proof and pressure-resistant motors.
