Studied and designed to feed filter presses; they can be supplied with single or double speed motors, with pump-motor coupling via belts and pulleys or with direct coupling via coaxial coupling.
Depending on the versions, a range of flow rates is available, ranging from 100 lt/min to 10,000 lt/min with indoor pressures up to 16 bar.
The bodies and impellers can be made of superalloys or spheroidal cast iron coated with special anti-abrasive rubber compounds.
The suction inlet is positioned so that the sludge does not come into direct contact with the mechanical seals, the latter made of tungsten carbide, drained with water and protected by a pressurised barrier chamber.
The functionality of the bearings is guaranteed by lubrication in an oil bath.
