The NEMO® BO/BS progressing cavity pump with hopper and coupling rod with feeding screw as well as force-feed chamber for improved product feed into the conveying elements is used for applications in the environmental technology, food and chemical industries.
The NEMO® BO/BS is particularly suitable for shear-sensitive, lubricating and non-lubricating, thixotropic, dilatant, highly viscous and crumbly media that do not tend to bridge, as well as for slowly flowing to non-free-flowing media with and without solid content. The difference between the BO/BS types lies in the inlet hopper. The BO series has a rectangular inlet hopper and the BS series has a square inlet hopper. Both pump types are used in almost all branches of industry for continuous, pressure-stable, gentle and low-pulsation conveying. This special design ensures a better product feed into the conveying elements. In addition, the progressing cavity pump ensures speed-proportional dosing of almost all media. In block construction with a flanged drive, this pump is particularly compact and economical.
