PTM - The manufacturer

For heavy duty mixers in biogas plants


As a highly specialised manufacturer, we bring many years of experience together with state-of-the-art technology. The result is a submersible mixer for the most challenging situations - the PHANTOM.

The PHANTOM is the product of our in-depth application knowledge in the biogas sector, and provides a comprehensive solution for your biogas plant. The PHANTOM combines the utmost efficiency and maximum durability in one product for the first time. Well-thought out and tested down to the last detail, a shielded mechanical seal in tandem execution provides for reliable sealing, for example. The motor with high reserve also resists even increased temperatures without a problem, providing a solution to the challenges posed by high-fibre and high-viscosity media.

Propellers in submersible mixers in biogas plants naturally sustain a lot of wear. This is why the PHANTOM is equipped with a monolithic propeller made of a high-performance plastic. Clearly superior to both conventional metallic and also glass-fibre materials, it delivers the required high level of efficiency and reliability even over a long period of use.

PHANTOM - our goal is your success!

Adaptation of the Phantom model range for low fill level applications.

The Typhoon 650 generates a strong turbulence, making it ideally suited for use in the residue storage tank.

The Typhoon can also be operated even at low fill levels thanks to its three-bladed propeller with a diameter of 650mm.
