    Environmental water and wastewater applications

    For decades, Watson-Marlow Fluid Technology Group has helped water and wastewater treatment plants safeguard end-product quality, reduce cost of ownership, and minimize risk.

    Our peristaltic pumps have no valves, diaphragms, rotors, stators, universal joints or lobes to fail. The risk of siphoning and gas locking, common in diaphragm pumps, is eliminated. They’re simple to operate, accurate, self-priming and capable of being run dry. This results in pumps that deliver:

    • accurate, contamination-free metering and dosing
    • reliable handling of slurries, viscous, abrasive and corrosive fluids
    • significantly lower total cost of ownership

    The combination of the right products, supported by a global network of experienced support, is the reason leading water engineers turn to Watson-Marlow Fluid Technology Group to help them meet today’s challenges.
