Camalot Dispensing Pumps

Camalot Systems designs and manufactures the most precise rotary positive displacement valve for dispensing materials in highly repeatable volumes. The precision of the valve is derived from superior mechanical, electrical, and software engineering that provide complete control over the volume of dispensed material.

The valve is powered by a D.C. motor. An electromagnetic clutch engages and disengages the Archimedian screw. Mounted above the screw is a bellow coupling that aligns the clutch and lead screw and reduces the impact of the Z-axis by more than 60%. The Archimedian screw is made from stainless steel and rotates in a furrow that is precision honed for a perfect fit. Constant, low pressure maintains a steady flow of material into the valve. The combination of constant motor speed, low air pressure, the software-controlled clutch, and the precise rotation of the Archimedian screw ensures a repetability that is far superior to pulsed air or piston dispensing systems.
