The Williams “W’ Series is a piston plunger pump with a mechanical seal. It is capable of precisely injecting chemical into a wide variety of process applications. Whether you need to inject a catalyst in a reactor for a refinery or high volume batch dosage treatments offshore such as biocides for water and fuel treatments. The “W” Series pump can deliver up to 90 gph (336 liters per hour at pressures up to 2500 psig (172 barg).
NOTE : (1) The minimum volume recommended for any pump should be calculated on the basis of 1/4 inch minimum stroke length per minute minimum speed with controller, or 1 stroke per minute with solenoid.
(2) The maximum discharge pressure is achieved using 150 PSI (10.3 BAR) air/gas supply pressure.
