What is Peristaltic Pump?
Simple design. The major components are only the pumphead, tubing and two or more rollers. Squeezing the tube and push the fluid forward. allowing the tube to re-expand draws in more liquid, and this action creates a self-priming, positive displacement pump. 

Design philosophy
1. High Output Gear Motor combines advanced electronics with essential torque at full speeds, regardless of viscosity. Surface mounted advanced electronic motor controls, assure reliable operation and long motor life.
2. Control ink flow with motor speed, not valves. Variable speed control allows accurate flow management without valves and by-passes.
3. Reversible flow for easy draining and flushing. Toggle type forward/reverse switch stops motor before reversing direction.
4. Splash-Resistant design with shielded rear and bottom vents for use in environments where it would be subject to splashes and spills in a messy environment.
5. Dual Roller Technology delivers full flow with fewer compressions reducing tube wear for maximum life.Rollers material is Kevlar-reinforce Nylon that is quite possibly the world's first“bulletproof” peristaltic pump roller. 
6. Design of permanent foot flange integral to the base assures ideal air flow and keeps the internal at a cooler temperature. 7. Patented “Straight-Thru” thread design allows the tube to run “straight-thru” from the bucket to thepress eliminating “pinch points’, where kinks from that slow the flow and weaken the tube. Threadpattern also locks the tube in place, eliminating snaking or creeping movement common in most peristaltic. 
8. “Swivel Lock Fasteners” design allows to release quickly the pump head cover, without tools or loose parts, facilitating a quick change of tubing. 
9. Housing material is Lexan, strong, light. It covers the motor and electronics to protect against damage. Baked-on powder coating provides a long lasting durable finish.
