KSB Introduces New Low-speed Submersible Mixer


KSB presents a new kind of low-speed submersible mixer for use in biogas production and waste water treatment. The new Amaprop 1380 can serve as a back-up mixer, scum breaker or flow accelerator. It can be used alone or in combination with larger mixers.

The new mixer for biogas plants has a hard-wearing propeller made of robust nodular cast iron designed for years of reliable service. Its contours were developed with the aid of computational fluid dynamics (CFD) simulations. It can generate high volume flow rates, producing an axial bulk flow.

Two mechanical seals in tandem arrangement reliably seal off the gearing and motor compartment. An oil reservoir between the two mechanical seals is filled with environmentally friendly oil that keeps the seal faces lubricated and cool. A leakage chamber between the oil chamber and the gear unit provides additional safety.

The cable entry is absolutely water-tight, and a plug connector in the motor space connects the cable to the motor winding, hence facilitating in-situ replacement of the cable.

Robust, quiet-running, long-life helical spur gears are used, and the three-phase motors occupy a rating range of 6 to 13 kW. The motors are series-equipped with maintenance-free bearings and temperature sensors – plus a moisture sensor - to protect the windings against overheating and ingress of moisture.

A stainless-steel lowering device makes it possible to adjust the mixer’s mounting angle and height with ease.
