Design
KSB Amacan K – Wet-installed submersible motor pump with non-clogging impeller, singlestage, single-entry, for installation in discharge tubes, explosion protection to ATEX II G2 T3.
Applications
Handling of pre-cleaned, chemically neutral waste water, industrial effluents and sewage, fluids not containing any stringy substances pre-treated by screens and sills, as waste water, mixed water and activated sludge pump in effluent treatment plants, irrigation and drainage pumping systems.
Function
The fluid enters the pump axially via the inlet of the pump casing (1) and is
accelerated outward in a radial flow by the rotating impeller (2). The required energy
is transmitted from the electric motor (7) to the impeller (2) via the shaft (4). In the
pump casing (11) the kinetic energy of the fluid is converted into pressure energy.
The rotational movement diverts the fluid flow in axial direction. The casing wear
ring (12) prevents any fluid from flowing back from the casing into the inlet of the
pump casing. At the rear side of the impeller, the shaft enters the casing via the
discharge cover (3). The shaft passage through the discharge cover is sealed towards
the fluid by a shaft seal (10). The shaft runs in rolling element bearings (5 and 8),
which are supported by a bearing housing (9) and a bearing bracket (6).
Standard
▪ Temperature monitoring of the motor
▪ Temperature monitoring at the lower bearing
