Smart Air Injection (SAI) is a customized package unit with many varied applications. The innovative combination of progressive cavity pump and compressed air conveying results in a low-pressure level in the conveying pipeline. This results in an extended service life and reduced investment and operating costs.
Smart Air Injection is used in the environmental sector for transporting sewage sludge up to 1,000 meters using compressed air and boundary layer injection – convenient, extremely low-friction, and energy-efficient.
Total energy consumption reduced by up to 72% compared to conventional conveying technologies
Long service life and low investment costs due to less expensive pipes and fittings with low pressure stability (PN 10)
Easy Maintenance Concept: Maintenance-in-Place possible - Smart Conveying Technology for rotor/stator replacement with minimal space requirements in less than one hour
Long transport distances of up to 1,000 meters and easily overcomes changes in direction and differences in height
Increased component lifetimes and up to 88% savings in maintenance costs due to extremely reduced discharge pressure of only 2-4 bar
Control and monitoring of all functions via the SAI controller and easy integration into all automation and control systems
Closed system with integrated cleaning function
Compressed air is pulsed into the pipeline to convey the pre-compacted sludge plug.
To reduce friction losses in the pipeline. To optimize costs the conveying capacity of the lubricant is automatically adjusted to the conveying capacity of the main pump.

The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.
For rapid replacement of the rotor and stator. Maintenance downtime reduced by up to 85%.
Ensures optimal feeding of the media. Quick and easy maintenance: available as a conical compression casing in conjunction with Smart Conveying Technology or as a sliding compression casing.
These pumps are equipped with a rectangular feed hopper with vertical hopper walls and a concentrically rotating ribbon screw. Even in the case of media with a high solids concentration, efficient emptying of the feed hopper and an optimum supply of viscous sludge into the pump's conveying elements is guaranteed.
Connected to the upstream dewatering machine. Controls the pump speed with a level sensor.
TSE monitors the temperature of the rotating stator and shuts down the pump when the limit value is reached to protect the pump from dry running.
