RPG Gear Pump Flow Management

 The Robotic Paint Gear pump range "RPG" is used for the supply of liquid paints, when a regular and accurate flow is mandatory, either solvent-based or water-based, for all SAMES KREMLIN automatic sprayers. This pump comes in 3 capacities defined by the number of cubic centimeters of paint delivered per revolution:
 

• 4.5 cc / rev
• 6 cc / rev
• 9 cc / rev

These different models allow covering a flow range from 8 to 65 l/hour. The choice is made with respect to the target flow and the rotation speed range. We recommend to run at less than 120 rpm. The gear pump ensures a paint flow that is proportional to its rotation speed. In the case of a distribution system, the material pressure regulator is to be connected before the pump, whereas a flow meter is always connected after the pump. Upstream pressure facilitates priming but also ensures the flow corresponding to the capacity and speed of the pump.
 
All the RPG range is fully compatible with the UPside CCV color change block as well as the innovative PaintSave push-out technology from SAMES KREMLIN. To allow high flexibility, these pumps can also fit perfectly the robot motor coupling. The Robotic Paint Gearpump "RPG" is 15% lighter than our previous range of gearpump. New pressure sensors are available to monitor the process with a compact design to be integrated directly in the robot process arm.
 

• Compact Design: Designed to be the most compact of the market integrating a paint pressure sensor with a ¼" only interface to reduce the paint loss during color change and ease the integration on robot arm.
• Fast Color Change: Thanks to the ADLC coating and the dedicated solvent valve to clean the gear teeth, the color changing is faster than ever.
• High Reliability: Lifetime of the pump is increased thanks to the fact that key operating components are made of ceramic.
