MEC-O-MATIC VSP Peristaltic Metering Pump – Variable Speed Chemical Feed | 0.13–97 GPD | Chlorine, pH, Coagulant Dosing | Self-Priming, Low Maintenance

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.

Key Features: Precise, Reliable Chemical Dosing

• Variable Speed Control – Potentiometer adjustment from 10% to 100% for highly accurate feed rates.

• Durable Design – Chemical-resistant ABS case, heat-treated all-metal gearing, and heavy-duty bearings for long-term performance.

• Quick-Release Pump Head – Exclusive twist-off, clear polycarbonate head resists acids and allows for fast tubing replacement.

• Self-Lubricating Roller Assembly – No tube adjustments required; reduces maintenance and downtime.

• Continuous-Duty Motor – Heavy-duty shaded pole gearmotor with lifetime lubrication ensures reliable 24/7 operation.

• Flexible Feed Rates – VSP-12 dispenses up to 12 gallons per day, and VSP-20 up to 20 GPD. Variable-speed control allows 10%–100% adjustment for precise dosing.
