Zoeller Pump 72 HD Series
Zoeller Pump’s 10 and 15 hp 72 HD Series is an expansion to its existing grinder product offering, now ranging from 1 to 15 hp. The units include a dual carbon ceramic shaft seal, moisture and thermal sensor, a buna-N gasket to protect the 3,450 rpm motor, and class F windings. Pumps are available in 208, 230, 460 or 575 volts using a three-phase connection. The 3- or 4-inch ANSI flanged horizontal discharge allows for easy adaption to a variety of grinder or solids-handling rail systems. Pumping performance ranges from 250 feet at shutoff and a maximum flow at 150 gpm at 50 feet TDH. Removable legs clear the bottom of the pump to allow debris to flow easier into the cutter assembly when used with a guide rail assembly. This assembly uses a 440 stainless steel with a Rockwell C hardness of 55-60 cutter and cutter plate in a scissor-like cutting motion that reduces solids down to 1/8 inch.
