Germany’s KSB Group has added a new submersible motor pump to its Amarex type series, suitable for applications including wastewater, sludge treatment and the transport of storm water.
The pump can handle wastewater containing long fibres, solid substances, fluids containing gas and sludge, service water and grey water. It is equipped with either free-flow impellers (F-max) or open two-vane impellers (D-max), with users able to choose the appropriate impeller types.
Pump variants featuring D-max impellers are available with a D-flector, which significantly increases resistance to clogging. A variety of material and mechanical seal variants allows the user to transport a wide range of corrosive and abrasive fluids.
The impellers’ non-clogging feature reduces maintenance requirements compared with conventional designs. The Amarex NG offers high levels of hydraulic efficiency combined with high-efficiency IE3 motors creating low energy consumption during operation. It has a maximum head of 42m and a maximum flow rate of 320 cubic metres per hour.
An environmentally friendly, non-toxic oil fill provides continuous lubrication of the mechanical seal, installation in the pump sump made via a ‘duckfoot’ bend. Moreover, a large range of adapter claws allows the use of duckfoot bends from other manufacturers.
Sealing between duckfoot bend and the pump discharge flange is by a newly developed water-tight and durable U-profile ring. Users also have several options when choosing the arrangement for placing the pump on the duckfoot bend: they can opt for guide hoop, guide wire, single guide rail or twin guide rail arrangement.
The pumps are designed for easy repair and maintenance, and at the end of the pump’s life, most of components can be dismantled and recycled.
