Line of stamped 304 stainless steel pumps with NPT connections includes ANSI-flanged centerline discharge models. Series 320-328 covers up to 385 gal/min and 275 ft of head. The pumps have a slip-fit O-ring/flinger design that prevents leaks caused by deformation as a result overtightening. They are mounted on a JM frame and incorporate a back pull-out design and weep holes in the impeller. The weep holes extend seal life by creating fluid movement in the seal cavity, says the manufacturer, which aids in venting of air at startup.
