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.
