Fluid pumping systems: how they work, types of pumps and selection criteria

Pumping systems operate with a specialised pump that is installed directly into the drum or other container. The liquid is sucked by the pump through a submersible tube and fed into the outlet pipe.

The main stages of work:

  1. Immersing the pump in the barrel: The pumping tube is lowered into the interior of the container.
  2. Liquid suction: The pump's working element creates a vacuum or mechanical pressure to lift the liquid.
  3. Transportation: The liquid is pushed through the outlet to the desired delivery point.

Components of the pumping system

  1. Pump:
    The central element that determines performance and fluid compatibility. The type of pump is selected according to the characteristics of the fluid:
    • Centrifugal pump: For liquids with low viscosity.
    • Gear pump: For thick and viscous liquids.
    • Diaphragm pump: For aggressive, abrasive or viscous media.
    • Screw pump: For use with delicate products.
  2. Immersion tube:
    The tube that goes down into the barrel. It is made of chemically resistant materials such as stainless steel, polypropylene or PVDF.
  3. Reason:
    • Electric drive: Delivers high performance and is suitable for continuous operation.
    • Pneumatic drive: It is used in explosive atmospheres.
    • Manual drive: An economical solution for small volumes.
  4. Controllers and filters:
    Ensure accurate fluid delivery and cleaning before transport.
  5. Additional accessories:
    • Adapters for different types of containers.
    • Fluid supply hoses.
    • Automatic shutdown systems when the set level is reached.

Areas of application

  1. Chemical industry:
    Pumping acids, alkalis, solvents and other aggressive substances from sealed containers.
  2. Pharmaceuticals:
    Precise dosing of active ingredients from containers to production lines.
  3. Food industry:
    Pumping out syrups, oils, liquid dough, dairy products and other foodstuffs.
  4. Cosmetics industry:
    Work with thick masses such as creams, shampoos, gels, oils.
  5. Oil and gas industry:
    Pumping fuels, oils, greases and other petroleum products.
  6. Cleaning systems:
    Pumping out reagents, detergents and disinfectants.

Features of pumping systems

  1. Compatible with various liquids:
    Thanks to a wide range of materials, the systems are suitable for transporting aggressive, viscous, thick, toxic and delicate liquids.
  2. Mobility:
    The systems are easy to install and move between different tanks.
  3. Energy efficiency:
    Modern models consume minimal energy while providing high performance.
  4. Durability:
    High-quality materials ensure a long service life, even in harsh environments.
  5. Performance control:
    The pumping speed can be adjusted to suit the fluid characteristics.

How to choose the right barrel pumping system?

  1. Fluid characteristics:
    • Take into account the viscosity, chemical composition, temperature and aggressiveness of the working environment.
  2. Material of execution:
    • Polypropylene or PVDF for aggressive substances.
    • Stainless steel for food or petroleum products.
  3. Productivity:
    • Select a pump with the appropriate flow rate for the volume of the vessel.
  4. Type of drive:
    • Electric for large volumes.
    • Pneumatic for explosive environments.
    • Manual for cost-effective solutions.
  5. Protection systems:
    • Availability of dry running protection, automatic shutdown or overflow sensors.
