Piston Pumps

The Series 2665/2685 WOB-L piston pumps by Thomas Products Div. (Sheboygan, WI) incorporates epoxy-coated head and valve plates for exterior corrosion protection, aluminum construction, and a Teflon piston seal that remains flexible even in cold. The pumps are intended for use where fan guards are not required; Series 2685 pumps include a stainless steel fan guard. Oil-less, non-lube pistons and cylinders prevent airflow contamination, while twin fans provide cooling of the motor and cylinder. All series 2265/2685 pumps provide up to 100 psi of pressure, and a pressure relief valve is also included. Thermally protected AC motors are of ultra-reliable permanent split capacitor design. Maximum flow for pumps equipped with 115 VAC 60 Hz single phase motors is rated at 3.68 CFM; maximum flow for pumps equipped with 220-240 VAC 50 Hz single phase motors is 3.23 CFM.
