    Water treatment pumpKey features of water treatment pumps

    Capacity

    The capacity of a pump is determined by its ability to pump a certain volume of water per unit of time. It is important to choose a pump based on the required water treatment capacity.

    Head

    The head of a pump shows how high it can lift water. For water treatment systems, choose pumps with a head that ensures efficient operation of all system components.

    Materials for pumps

    The materials from which the pump is made must be resistant to corrosion, chemical attack and abrasion. Stainless steel, plastics and composite materials are popular choices for pumps in water treatment systems.

    Types of pumps for water purification

    Centrifugal pumps

    Centrifugal pumps are widely used in water treatment systems due to their high performance and ability to generate high pressure. They are suitable for pumping large volumes of water.

    Dosing pumps

    Dosing pumps are used for the precise injection of reagents in the water treatment process. They automate the dosing process, ensuring high accuracy and repeatability.

    Submersible pumps

    Submersible pumps are used to pump water from wells, boreholes and tanks. They can operate completely submerged in water, making them ideal for deep water sources.

    Industrial pumps for water purificationChoosing a water treatment pump

    When choosing a water purification pump, it is important to consider not only its technical characteristics, but also the operating conditions, the type of water treatment system, and the requirements for the quality and quantity of purified water. It is recommended that you consult with professionals to find the best solution.

    Maintenance and operation of water treatment pumps

    To ensure the long-term and trouble-free operation of water treatment pumps, it is necessary to carry out regular maintenance, which includes checking the condition of the pump, cleaning it from dirt and replacing worn parts.

    Conclusion

    Water treatment pumps play an important role in ensuring the efficiency and reliability of water treatment and purification systems. The correct selection, installation and maintenance of pumping equipment can significantly improve the quality of treated water, as well as save resources and money for system operation.
