The KSB Group has launched a new generation of its time-tested submersible grey water pumps. The AmaDrainer 3 type series is available in four sizes, and is the company’s response to its customer requests for a design that is more compact and easier to handle.
The AmaDrainer 3I is a compact design with integrated float switch and a maximum diameter of 155mm, making the pump ideal for narrow spaces such as light wells, for example. The maximum head is 11.3m. All four sizes are designed for continuous duty at a fluid temperature of up to 70oC, and for short periods even up to 90oC.
A new feature is the integrated low water level intake. By removing the suction strainer, the two smaller pump sizes can achieve residual water levels as low as 2mm. The larger pump sizes are characterised by free passages of up to 35mm, so they can also transport coarse matter contained in the waste water. For aggressive waste water and other fluid handled, a special variant is available for all sizes.
All four pump sets feature a plastic casing. A jacket-cooled motor permits operation even when the motor is not submerged. In addition, AmaDrainer 3 comes with integrated motor protection. Fitted with a 10m power cable, the pump set allows for more flexible handling. The submersible motor pumps are robust, and provide operating reliability.
The AmaDrainer 3 series can be used for draining shafts and cellar rooms as well as for extracting water from reservoirs and rivers. In emergency situations, the pumps can be used for applications such as draining external basement stairwells and underground passages. The pump sets are supplied ready to be plugged in, enabling fast installation and commissioning.
