PSM Submersible Mixer

A revolution in mixing

The PSM submersible mixer is the most innovative mixing technology currently available on the markt. 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. Depending on the initial situation, CO2 and electrical savings of 50% or more can be realized.

Benefits at a glance

Efficient

Average power input of 8kW – 12.5kW

Powerful

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

Intelligent

DMC control unit regulates everything automatically

Protected

ATEX and Cl. I, Div. 1 approved

Robust

Gearless drive, high-quality components

Economical

Electrical savings potential of up to 50%

Average power input

The PSM submersible mixer with an average power input of 8kW to 12.5kW is suitable for installation in all common tanks of biogas plants, wastewater treatment facilities and industrial applications.

With the permanent synchronous magnet (PSM) motor, a gearbox is completely avoided. Less wear means longer service life of the mixer and of course, less maintenance costs. Also, because of its high thrust and motor torque, floating layers and high solid digesters do not pose a problem for the PSM.

PSM Features

Schaubild PSM - Rührtechnik

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

Robust housing with reinforced suspension

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 flushless mechanical seal as a 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 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 you to switch over to lower cost substrates with high dry matter content, such as grass or manure. Additionally, the geometry of the mixer blades ensures optimum flows to achieve gentle metabolic/gas exchange processes for the bacteria and uniform mixing of the entire fermenter. This results in significantly higher gas yields.

Intelligent mixing

The DMC (Dynamic Mixer Controller) is our control unit developed exclusively for the PSM mixer. It expands the possibility of the PSM and takes full advantage of output power and energy consumption. The DMC regulates the PSM 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 submersible mixer. Our Service Box Classic and Service Box Pro 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.
