A starting point for selection. The following maximum flow rates are reference values for selection; actual performance depends on the installation.
½-inch connection
49.2 L/min maximum flow. ½–14 NPTF fluid connection. Published maximum particle diameter: 2.4 mm.
1-inch connection
178 L/min maximum flow. 1–11.5 NPTF fluid connection. Published maximum particle diameter: 3.2 mm.
1½-inch flange option
378 L/min maximum flow. 1½-inch ANSI flange fluid connection. Published maximum particle diameter: 6.4 mm.
Plastic-series reference values only. Confirm fluid compatibility, diaphragm materials, particle characteristics, suction conditions and air supply. A published maximum is not a guaranteed duty point.
