Stingray Diaphragm Pumps & Parts

Mec-O-Matic Stingray Pump Series Positive Displacement Metering Pumps for water treatment chemical solutions

The Mec-O-Matic Stingray Series of positive displacement pumps offers a rugged, chemical resistant, flame retardant plastic housing and wetted components with a continuous duty motor featuring lifetime-lubricated, heavy-duty gearing. The diaphragm and Viton seals are PTFE coated for a long life in high corrosive applications. For high reliability, the check valves are spring loaded. To assist in priming and to prevent tubing rupture and/or motor failure the 100 Series Stingray features a patented relief/release valve. The Stingray Series offers a range of models, offering feed rates from 8 GPD to 90 GPD and with operating pressures up to 100 PSI. Agency approvals are also available. Complete systems are also available, with solution tanks up to 200 gallons. A wide range of accessory fittings and assembles are available to enhance performance and simplify operation.
The Stingray series pumps have the ETL Sanitation Mark (Certified to NSF Standard 50 for pools, spas, or hot tub systems).
