The Azcue KB Progressive Cavity Pump is a quality and robustly constructed solution designed the transferring of difficult fluids even over long distances thanks to the high pressures they can achieve. Thanks to its low internal velocity of helical rotor pumps, the KB can transfer viscous liquids containing particles and contaminants efficiently such as sewage and slurries, as well as shear sensitive mediums that have a structure can be impacted when high shear is applied.

The KB is a more compact and cost effective progressive cavity pump compared to the KL model, as rather than having a bearing bracket, the motor is close coupled directly to the pump housing. Available in smaller sizes and at lower flows than the KL, it is ideal for less abrasive conditions and smaller volumes of liquid being transferred, whilst still being able to handle solids up to 95m.

In order to ensure reliable operation and a long service life, the KB eccentric screw pump has a fully encapsulated cardan shaft and joint with lifetime lubricated needle roller bearings that prevent wear and mean they don’t need to be regularly maintained. It also benefits from joint connections that have continuous diameters, ensuring there is a constant flow within the suction housing and blockages do not occur.
