Bulk Solids Pump Feeders BSP

Coperion K-Tron

Gentle, precise feeding of free-flowing materials

The unique Coperion K-Tron Bulk Solids Pump (BSP) feeders have been specifically designed and engineered to provide gentle, precise feeding of free-flowing pellets, granules, flakes, powders and friable products. The BSP feeders do not use the usual screws/augers, belts or vibratory trays to convey the material. Instead, they utilize positive displacement action to feed free flowing materials with astounding accuracy, offering uniform discharge, consistent volume and gentle handling. All BSP feeders have vertical rotating discs that create a product lock-up zone, conveying the material smoothly from storage hopper to discharge outlet, achieving true linear mass flow.

The BSP-100 features a single feeding duct formed by two rotating discs. It includes a conical inlet transition piece which can be combined with a variety of standard extension hoppers. A slide gate on the inlet allows for material shutoff and removal of feeder for cleaning and hopper emptying. The BSP-100 is available as a volumetric unit or as a gravimetric unit with a choice of two platform scales, single point suspension scale or three-point suspension scale.

Product contact parts are manufactured of electroless nickel plated cast aluminum. Hazardous location options (ATEX, NEC) available. Consult Product Specification Sheet for more details.


Feed Rates
Nominal feed rate: 2 to 400 dm³/h (0.07 to 14 ft³/h) at 0.3 to 60 rpm
Theoretical displacement: 0.11 dm³/rev (0.0039 ft³/rev)

The BSP-135 is a slightly larger version of the BSP-100, with all the same features except that it has three feeding ducts instead of one. The BSP-135 is available as a volumetric unit or as a gravimetric unit with a choice of platform scale, single point suspension scale or three-point suspension scale.
