K-Tron's Bulk Solids Pump™
K-Tron Expands Bulk Solids Pump™ (BSP) Feeder Line
with Introduction of BSP Model 150;
Volumetric and Gravimetric Models Available
Pitman, NJ--- (May 21, 2004)--- K-Tron expanded the company’s Bulk Solids Pump™ Feeder Line with the introduction of the BSP Model 150 at the May Powder Show in Chicago. The BSP 150 is the third model in the company’s new Bulk Solids Pump™ (BSP™) feeder line; models BSP 100 and BSP 125 were introduced in December at the ChinaPlas Show. This revolutionary new concept for feeding bulk material utilizes positive displacement action to feed free flowing materials with astounding accuracy, offering uniform discharge, consistent volume and gentle handling.
The BSP employs one or more specially designed vertical rotating spools that create feeding ducts. Incoming material is captured in the duct and rotated to discharge. While within the duct, the material “locks up” and moves in “plug flow,” moving smoothly from storage hopper to discharge outlet, achieving true linear mass flow, producing excellent linearity and breakthrough accuracy levels. The smoothness of the discharge is evident to even the untrained eye compared to the pulsing flow from a rotary valve or screw feeder. The smooth, even flow results in significantly improved accuracy levels, especially at short one-second sample durations.
The BSP 150 utilizes four feeding ducts to reach feed rates of 1.6 to 160 ft3/hr (45 to 4500 dm3/hour). While within the ducts, the material “locks up” and moves smoothly in “plug flow” from storage hopper to discharge outlet, achieving true linear mass flow, producing excellent linearity and breakthrough accuracy levels. Both gravimetric and volumetric models are available and the BSP 150 can also be incorporated into K-Tron’s new K4G continuous gravimetric blender.
The two smaller K-Tron Bulk Solids Pump feeder models introduced in December are the Model BSP 100, utilizing one duct to feed 0.07 to 7 ft3/ hour (2-200dm3 /hour), and model BSP 125, utilizing two ducts to feed 0.32 to 32 cu3 ft/hour (9-900 dm3/ hour).
The accuracy improvements the BSP produces over screw feeders were demonstrated in controlled tests at K-Tron’s Pitman test lab. The same three materials were fed on volumetric versions of the BSP 125 and a K-Tron single screw feeder: plastic pellets, wax granules and citric acid granules. Automated data collection of catch samples enabled durations as short as one second to be reliably obtained. Feeder accuracy was measured for both linearity and repeatability. The volumetric BSP 125 approached a linearity error of +/- 0.1 percent at over its 100:1 turndown range compared with the volumetric screw feeder’s average error of +/- 2.0 percent over the same turndown. The BSP also exhibited a 50-70% improvement in repeatability over the screw feeder. Loss-in-weight versions of the BSP would offer even further improvements in accuracy.
The BSP’s open design minimizes material build-up in the feeding zone. With no pockets or screws and only one moving part, the compact BSP feeder is cleaned in seconds, making it ideal for applications with frequent material changes. In addition to offering ease of cleaning, the simple design allows for economic pricing as well.
The Bulks Solids Pump feeder uses a brushless direct drive stepper motor and incorporates K-Tron’s Smart Stepper Motor Drive. Several discharge options are available to meet a variety of downstream needs.

K-Tron Debuts Bulk Solids Pump™ (BSP) Model 150
in Worldwide Introduction at Powder Show 2004 in Chicago
Pitman, NJ--- (April 28, 2004)--- The worldwide introduction of the K-Tron Bulk Solids Pump™ Model BSP 150 will take place at the Powder and Bulk Solids Trade Show in Chicago, May 4-6, 2004. The K-Tron Feeder Group will also exhibit in North America for the first time BSP Models 100 and 125, first introduced by K-Tron at the ChinaPlas Trade Show in December 2003. This revolutionary new concept for feeding bulk materials does not use the usual screws/augers, belts or vibratory trays to convey the material. The Bulk Solids Pump (BSP) utilizes positive displacement action to feed free flowing materials with astounding accuracy, offering uniform discharge, consistent volume and gentle handling.
The BSP employs one or more specially designed vertical rotating spools that create feeding ducts. Incoming material is captured in the duct and rotated to discharge.

The BSP 100 utilizes one duct to achieve feeds rates of 0.07 to 7 cu3 ft/hour (2-200 dm3/hour). The BSP 125, with two ducts, achieves feed rates of 0.32 to 32 ft3 / hour 9-900 dm3/hour). The BSP-150 utilizes four ducts to reach feed rates of 1.6 to 160 ft3/hr (45 to 4500 dm3/hour). Both gravimetric and volumetric versions of all three BSP models are available. Gravimetric versions of the BSP 100 and 125 will be available in both platform and suspension scale models. The loss-in-weight version of the BSP 150 will only be available hanging on a suspension scale. All three models can be incorporated into K-Tron’s new K4G continuous gravimetric blender.
