Dosing technology in industrial metalworking

When perfection is not left to chance.

In the metalworking industry, optimisation and precision are mainstays of manufacturing.

Liquid process media must be prepared and maintained in the correct quantity and composition at all times. Variations in pressure, flow rate, temperature, viscosity or suction height are possible sources of error here. With optimally matched metering systems, we counteract these problems before they occur. We offer a wide range of dosing systems from Dosatron (water-driven proportional dosing units) and high-precision electronic dosing pumps from Iwaki and Etatron, plus application-specific modules with these components.

Mixing and dilution of emulsions and cooling lubricant with dosing systems.

Cooling lubricants and emulsion solutions have their place in manufacturing process chains. In order to be able to operate a system properly, it is important to maintain the correct mixing ratios and eliminate sources of error when producing water-mixed cooling lubricants and mixing emulsion and solution. profluid has 20 years of experience in the use and analysis of cooling lubricants and offers you highly professional advice in this regard..


Proportional dosing

  • Volumetric, mechanical proportional dosing, independent of water flow rate, water pressure and line impacts

  • Dosing rates from 0.03 - 0.3% / 0.2 - 2% / 0.5 - 5% / 1 - 10% / 5 - 25%

  • Water flow rate from 10 l/h

  • Working pressure 6bar (4bar at 25% model)

  • Series switching for multiple dosing units for multi-component dosing

  • Supplied as single unit or completely pre-assembled on PE plate for wall mounting

    with filter, pressure reducer, system separator, impact damper, non-return valve and ball valves.

Optional

  • Mobile version with drip tray for 200l tanks available

  • On request with concentratmangel probe and water supply cut-off.  


Further application possibilities


Degreasing of surfaces and workpieces

When degreasing surfaces or workpieces, alkaline or acidic corrosion inhibitors are used. Correctly adjusted baths provide clean and grease-free parts, protect against corrosion and ensure economical use of bath additives. 

Water-based quenching and hardening media

Thermal treatment is a critical moment in many productions, where high scrap may be produced. If the quenching and hardening media are optimally dosed and coordinated, this reduces scrap and production is more efficient.

Hygiene and biofilm control in evaporative cooling systems and hot water pipes

Cooling tower and hot water pipes must be installed and operated in the EU in accordance with VDI2047 and VDI6023 or corresponding national regulations of the member states. This includes the control of legionella and other microorganisms as well as the addition of corrosion protection agents and hardness stabilisers. 

Systems that are made for the job

Our (pump) systems are insensitive to outgassing additives, to pressure, temperature  and flow rate fluctuations and guarantee safe, homogeneous dosing. In addition to high-quality dosing pumps, we offer modules tailored to your requirements with pumps, fittings and interfaces that can be easily fine-tuned on site. In addition to user-friendly and easy-to-maintain currentless (hydrodynamic) systems from Dosatron, our portfolio also includes high-precision electric pumps from Iwaki and Etatron. We also use the products of these manufacturers in our modules.
