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.

Features of the Azcue KB Progressing Cavity Pump: High pressure progressing cavity pump Self priming to handle difficult suction conditions Enables the free passage of solids up to 95mm Max viscosity of 200,000 mPas Compact close coupled pump head to drive Lifetime lubricated roller bearings Equivalent diameter joint connections to prevent blockages Low pulsation, continuous flow Suction housing with large inspection and clean openings Easy to replace cartridge format seal package Available in cast iron or stainless steel Electric or hydraulic motor driven Marine Applications: Industrial Applications: Oily or dirty bilge water Black/grey water pump including toilet waste Highly contaminated water water pump Fish waste and guts Any viscous fluids Refinery oil sludge Cargo and marine fuel transfer Sewage pumping Slurries, mud and sludge transfer Highly contaminated waste water pump Food waste, organic matter and biowaste Paper and pulp Shear sensitive products Any viscous fluids and fuels Material options for the KB eccentric screw pump: Cast Iron Construction Grade Steel Stainless Steel Hardened Tool Steel FPM Silicone EPDM POM Casing X X X Flanges X X X Joint X X Rotor X X Stator X X X X Bilge Water Transfer – Progressive Cavity Pumps One of our repeat clients, a supplier of parts to the marine market, approached us with an enquiry for three pumps for their customer. These were needed for the pumping of bilge water onboard a vessel. Water collected in the bilge of a ship is typically harsh in nature due to the presence of oily sludges, waste and debris that may be contaminating it. Therefore, unlike the clean water pumps they had onboard, a typical centrifugal pump is not suitable as it is likely to clog and leak.

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. − + Why use a progressive cavity pump? 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. − + What are progressive cavity pumps used for? 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. − + Are progressive cavity pumps self priming? Yes! A progressive cavity pump's tight tolerances mean it has excellent suction capabilities. − + Can progressive cavity pumps handle solids in my fluid? 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. − + Can these pumps be supplied with hopper? 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. − + Can progressive cavity pumps run dry? 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.
