DC Pumps

Magnetic Coupled DC Pumps (INTG series)

The INTG series consists of small, magnetically coupled centrifugal pumps with an integrated brushless DC motor (BLDC). They are sealless and couplingless, wear-free in the drive and made from highly chemical-resistant PPS - ideal for apparatus and systems handling critical media such as acids, alkalis and organic liquids.

Compact Plastic Centrifugal Pumps with Brushless DC Motors (BLDC)

The INTG series belongs to the group of magnetically coupled centrifugal pumps. The pump impeller is driven by a brushless DC motor, which allows infinitely variable speed control and low power consumption. The INTG pumps can be used in a wide variety of industrial applications.

Materials and Chemical Resistance

Our INTG pumps are made from high-performance thermoplastic PPS (polyphenylene sulfide). PPS is resistant to a wide range of aggressive media and is ideally suited for use in the chemical and pharmaceutical industries. PPS also remains dimensionally stable at media temperatures of up to 107 °C while offering high strength and hardness.

Fields of Application

  • Transfer and circulation: circulating and recirculating liquids
  • Server and electronics cooling: transporting coolant to the heat exchanger
  • Medical technology: handling liquids in medical devices
  • Cooling systems and coolants: cooling of laser systems and industrial machinery
  • Hydronic systems: HVAC installations in buildings
  • Marine applications: cooling and transfer on ships and offshore installations
  • Fuel cells: coolant transfer in fuel cell systems
  • OEM solutions: individual adaptation of duty point and dimensions to your requirements

Tailor-Made OEM Solutions

If the duty point required for your application or the dimensions of the standard pumps do not fit, please contact us. We specialise in OEM solutions and will be glad to develop the pump you specifically need together with you.

Protection class

  • Sealless and couplingless, therefore leak-free
  • Wear-free and maintenance-free thanks to the brushless drive
  • High efficiency due to low friction losses
  • High power density in a small installation space and at low weight
  • Flexible speed control via voltage or 0-5 V signal




Frequently Asked Questions about Magnetic Coupled DC Pumps

What is a magnetic coupled DC pump?

A compact, magnetically coupled centrifugal pump with an integrated brushless DC motor (BLDC) that operates without seals or couplings, with minimal wear and infinitely variable speed control.

What are the advantages of a BLDC motor over a conventional drive?

The absence of brushes makes the drive wear-free and maintenance-free, increases efficiency through lower friction losses and delivers high torque within a small installation space.

What temperatures is the INTG series designed for?

The material PPS remains dimensionally stable and chemically resistant up to a media temperature of 107 °C.

Does VENTAIX also offer OEM adaptations of the INTG pumps?

Yes, various connections and control options (analogue or digital) are available. If your requirements differ, we will be happy to develop a specific solution with you.
