Plastic Body Pumps

The most important advantage of these pumps is to prevent seal leaks caused by aggressive and dangerous chemicals, besides being economical. Thus, dangerous chemicals are prevented from harming the environment and people.

Polypropylene and PVDF body plastic pumps are ideal for many applications where the pressure is not too high (maximum 6 bar). Both self-priming and non-self-priming models are available for these two body options.

The equipment used for the transfer of liquid-phase fluids from one place to another is called a pump. Pumps have a wide range of uses. It is used in almost every technical application from metal surface coating to automotive, mechanical installations to oil and gas industry, agriculture to medicine. The operating principles of the pumps may differ depending on the location and purpose of use. Pumps can be produced in more than one type. Likewise, it is possible to produce pumps at different capacity levels depending on the liquid they deliver and how much they pressurize this liquid. Pumps can be classified according to the type and chemical properties of the liquid. Accordingly, the design of the pumps may vary according to fluid types such as water, acid, solvent, oil, sludge, etc. In case the substance to be transferred is any acid or acid-derived chemical, the pumps can be called Acid Pumps.

What is an Acid Pump?

The type of pump used to transfer or circulate liquids with acidic properties from one place to another can be called Acid Pump. The most important feature of acid pumps is that their material selection such as design and body, o-ring, bearing, etc. is made in accordance with the acid used. Since acids generally have corrosive effects, it is necessary to use materials that are resistant to acid for longer and more efficient transfer in the places where the acid comes into contact with the pump.

What Does an Acid Pump Do?

Acid pumps, especially used in the chemical and coating industry, can be used in the transfer of dangerous liquids even at high capacities, thanks to their centrifugal feature and electric motors. Centrifugal pumps, which are generally made of thermoplastic material, can be defined as types of electric motor pumps used in processes to transfer liquids quickly and efficiently and vary according to their capacities.

One of the most important options in acid applications is magnetic pumps. Thanks to its fan surrounded by magnets inside, it can be used to transfer dangerous fluids with its magnetic force. In cases where the fluid is sensitive, the use of acid pumps is preferred. When choosing an acid pump, the type of fluid and its chemical resistance should be considered.

Due to their special design, magnetic coupling pumps prevent leakage of chemicals, corrosive liquids, explosive and flammable liquids. Thus, they prevent the occurrence of situations that can be extremely dangerous for the people who take care of the pump and the environment, and allow the application of occupational health and safety principles. Since the fluid is kept in a closed chamber and provides transfer, it reduces the leakage and leakage problems caused by the gland to zero. Another advantage of the sealing feature is that it prevents the loss of valuable fluids and can eliminate possible refill costs. Pumps with magnetic coupling (glandless) stand out with their reliability. Thanks to their simple design, their maintenance needs are minimal. Compared to pumps with mechanical glands, it has the advantage of operating without interruption at minimum time loss and maximum production capacity in the facilities, thanks to the low maintenance periods and the ease of this maintenance process. O-rings and bearings must be checked at regular intervals to ensure that there is no wear/tear due to the aggressiveness of the chemicals and acids being transferred. Coupling can be done very easily as there is no need for motor/pump adjustment.

How to Use an Acid Pump?

Acid pumps are preferred in the chemical industry and in processes that require chemical transfer using dangerous, aggressive, valuable acids. They can be used in tankers carrying acids, bases, chemicals, solvents, pharmaceutical raw materials, sea water or brine, cleaning injection molds, baths used in surface coating and galvanization industries, transfer of ultrapure water, high pressure transfer of chemicals in waste water treatment plants and many more industries. The main feature of acid pumps is that they are generally used in the process of transferring aggressive and corrosive liquids.

Acid Pump Usage Areas

Acid pumps are generally used in liquids that are considered dangerous and have a corrosive effect. Acid pumps can be used in almost any process where these liquids are used. Accordingly, the liquids and applications in which acid pumps are used can be listed as follows:

  • Chemicals with acidic properties, especially sulfuric acid, hydrochloric acid;
  • Acids used in acid baths in surface coating processes;
  • All kinds of solvents and chemicals;
  • Fluids in tankers carrying chemical liquids;
  • Chemicals used in treatment plants;
  • Transfer and circulation of all kinds of chemicals with abrasive effect.
Acid Pump Types

Acid pumps are divided into different categories, depending on their operating principles. Pumps, whose body material is made of thermoplastic material for almost all, can operate with shaft gland or magnetic coupling. In addition, acid pumps also have submerged pump types. There is the need to use additional sealing element and leakage problems arising from this in the models with gland. Since there is no leakage risk in magnetically coupled centrifugal acid pumps, they are considered as a much better and advantageous alternative to gland models.

Magnetic coupling pumps have the feature of preventing leakage and emission thanks to their special sealing design. Therefore, they are suitable for pumping corrosive and dangerous liquids. These pumps, which have a simple structure, are also economical in terms of repair and spare parts costs. The movement of the external magnet placed on the drive shaft leads to the internal magnet attached to the impeller, which rotates and moves the fluid along the pump. Thus, the transfer is made.
