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 95mm.
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.

FAQs
It consists of a spiralled helical rotor (like a cork screw) that sits tightly inside a rubber stator/sleeve. As the rotor turns inside the stator, it forms a set of fixed-shaped cavities that progress along the length of the stator and force the fluid inside to move along with them as they turn.
Their pressure capabilities and viscosity handling is unrivalled, which means that whilst they are quite expensive in design and large in footprint, they are often selected for applications when all other pumping technologies will fail.
The design is best suited to highly viscous and lubricating fluids including oils, sludges, waste matter, biomass, pastes and grape pressing that may contain very large solids, as well as pumping viscous products over long distances.
Yes! A progressive cavity pump's tight tolerances mean it has excellent suction capabilities.
Yes they have excellent solid handling capabilities! However, it should be noted that abrasive fluids e.g. low viscosity/water based fluids containing solids may cause shorter stator wear.
Our progressing cavity pumps can be supplied with auger feed allowing non-flowing mediums such as dry sludge and waste matter to be pumped without clogging. We can also provide liquid injection ports which are popular when liquid waste is added to dry content waste to allow it to flow.
No! Even short period of dry running can result in damange to the rotor and stator, making dry run protection a must if there is risk of this.
