MEC-O-MATIC Dolphin Series Peristaltic Metering Pump – NSF 61 Chemical Feed Pump with 1–100% Control for Chlorine, pH & Water Treatment | 0.13–97 GPD

MEC-O-MATIC Dolphin Series Peristaltic Metering Pumps with Percentage Control – Reliable Chemical Feed for Water Treatment

The MEC-O-MATIC Dolphin Series Peristaltic Metering Pumps are engineered for precise, reliable, and low-maintenance chemical dosing in water treatment and industrial applications. These NSF/ANSI 61 and CSA B483.1 certified pumps are trusted for low-pressure chlorine, fluoride, enzyme, and a wide range of chemical feed applications.

Built with a rugged chemical-resistant ABS housing and heat-treated, all-metal gearing, Dolphin Series pumps are designed to last even in the harshest environments. The clear polycarbonate, acid-resistant pump head allows quick inspection, while the self-priming, self-lubricating roller assembly ensures long-term durability without adjustments. With programmable percentage control from 1–100% within a 10-minute cycle, operators enjoy flexibility in chemical feed rates ranging from 0.13 gallons up to 97 gallons per day.
