PSM XP Submersible Mixer

Flexible Mixing for your Toughest Applications

The PSM XP submersible mixer is the most innovative mixing technology currently available on the market. The powerful, gearless direct drive combined with the dynamic mixer controller delivers a mixing system that gets the most out of the energy it consumes. With full torque right off the line, floating layers and high solid digesters do not pose a problem for the PSM XP.

High torque motor with full power (up to 800Nm) even at low speeds (between 80rpm and 150rpm)


DMC control unit regulates everything automatically


Explosion proof according to Cl. I, Div. 1


Gearless drive, high-quality components


Electrical savings potential of 50% and more

Average power input

The PSM submersible mixer with an average power input of 7.5kW (10HP) to 12.5kW (16.5HP) is suitable for installation in all common tanks of biogas plants, wastewater treatment plant anaerobic digesters or anoxic tanks.

With the permanent synchronous magnet (PSM) motor, a gearbox is completely avoided, and high torque is available as soon as the mixer starts. Less wear means longer service life of the mixer and of course, less maintenance costs.

PSM XP Features

Schaubild PSM XP - Rührtechnik

State-of-the-art drive technologyPowerful direct drive without gear unit

Robust housing available in epoxy coated ductile iron or 316 stainless steel

Dedicated high thrust bearings independent of motor roller bearings

Optimized 3D propeller

2 independent liquid seals prevent nuisance alarms and eliminate frequent maintenance. The first barrier is a pair of lip seals with a flushless mechanical seal as secondary protection.

The 3D blade geometry has been designed, improved and optimized to perfection with an ideal ratio of shear force and fluid flow. The result is consistently mixed digesters and bioreactors with maximum gas yield.

Start saving now

Decreased mixing time and reduced energy consumption due to controlled speed and torque of your PSM XP mixer result in a savings potential of up to 50%. The powerful PSM mixer can generate a shearing force of up to 5.3kN, which enables wastewater treatment plant co-digestion or high solids digestion. Additionally, the backward sweeping propeller prevents rags or fibres from snagging on the propeller. The PSM XP mixer guarantees a uniform heat distribution and assimilation of influent sludge for maximum contact with microorganisms.

Intelligent mixing

The DMC (Dynamic Mixer Controller) is our control unit developed exclusively for the PSM mixer. It expands the possibility of the PSM XP and takes full advantage of output power and energy consumption. The DMC regulates the PSM XP according to the operator’s needs or the requirements of the mixing application. This all takes place fully automatically without intervention by the operator. Additionally, the DMC outputs data and allows for insightful understanding of the mixing process.


PSM + Service Box

We offer custom mixing equipment and installation solutions for the PSM XP submersible mixer. Our Service Box Classic, Service Box Pro and Service Box HP are equipped with an integrated mixer post pivoting bracket and a gas lock service opening to mention just a few of advantages. With the Service Box you can adjust the height of the mixer any time or rotate it to the left and right in order to mix the content of the entire tank.
