High Heating Power without Hot Surfaces
HOUTTUIN’s non-contact, friction-based screw friction heating pumps are extremely versatile and can operate at temperatures up to 400°C. Our horizontal or vertical heating pumps provide a robust solution for simultaneous heating and pumping of fluids in one compact unit. They avoid hot surfaces and use hydraulic friction to efficiently heat the fluid. An impressive heating capacity of up to 2000 kW per pump is possible, and multiple heating pumps can be operated in parallel. With an innovative self-cleaning feature, our heating pumps minimize the risk of clogging and there are no heat exchanger surfaces to foul.

Efficient Heat Production in Heating Pump Applications
HOUTTUIN twin-screw pumps are a popular solution for heat generation in heating pump applications. Thanks to their innovative design, these pumps enable extremely efficient heat generation in thermal processes. The unique screw profile ensures a continuous and uniform heat transfer, optimally adapted to your requirements.
The twin-screws and their precise fit provide smooth and efficient heat transfer regardless of the temperature and viscosity of the fluid. This ensures smooth heat transfer without temperature fluctuations, while maintaining the quality and integrity of the fluid being transferred. The heat pump is usually equipped with an electric drive (e-motor) to help reduce the carbon footprint, but other drive types are available.



Our twin-screw pumps are designed for efficiency, ruggedness and reliability in thermal applications. The slim design and innovative technology ensure trouble-free heat generation with minimal effort. The simple design of our twin screw pumps contributes to trouble-free operation and high system availability.
A characteristic of HOUTTUIN twin-screw pumps is that they are self-priming. This makes starting easier and speeds up commissioning. They also have a low NPSH (Net Positive Suction Head), which means they can operate efficiently at low pressures without the risk of cavitation. These features are especially important in heating applications with different fluids to ensure optimal performance and long pump life. You can count on our pumps for reliable and efficient heat generation, regardless of pressure conditions.
