Description
MEC-O-MATIC VSP Series Peristaltic Metering Pumps with Variable Speed Control
The MEC-O-MATIC VSP Series Peristaltic Metering Pumps deliver precise, adjustable chemical dosing for chlorine, fluoride, enzymes, and a wide range of other treatment chemicals. Designed for low-pressure applications, these self-priming tubing pumps provide reliability, accuracy, and long service life—all while requiring minimal maintenance.
Built with a rugged, chemical-resistant ABS housing and heat-treated all-metal gearing, the VSP Series stands up to demanding environments. A variable-speed gearmotor with potentiometer control allows operators to adjust feed rates from 10% to 100%, providing flexibility for exact dosing requirements in municipal water treatment, pool and spa maintenance, and industrial chemical processes.
