Conveying and cutting in one process step without expensive additional equipment, this is exactly what the hopper pump with integrated cutting device makes possible. With the progressing cavity pump, for example in the food industry, large solids such as pieces of fruit or vegetables can be easily and quickly chopped and pumped for further processing.
The BO/SO progressing cavity pump with hopper and coupling rod with feeding screw and force-feed chamber is employed in almost all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance. The hopper housing with cutting unit guarantees optimum feed of chunky medium into the conveying elements. If the medium passes the force-feed chamber with the cutting unit the larger fruits and vegetables are cutted immediately. This unit consists of a rotating knife with three blades and a variable number of stationary knives adjustable to the size and consistency of the particles. Optionally the pump can be equipped with an additional cutting unit at the discharge flange of the pump. With its perforated disc and rotating knife it allows for further fine definition of the particle size. As any other progressing cavity pump also the BO/SO pump has the ability to dose the conveyed media in proportion to rotation speed. In block construction with a flanged drive, this pump is particularly compact and economical In addition, the pump is characterised by low investment, operating and maintenance costs. However, it is also available in bearing block design with a free shaft end. This means that the pump can be operated with different types of drive, such as servo motors, diesel engines or hydraulic drives.
