SHA Series - Submersible Grinder System - Brochure

SHA SERIESSUBMERSIBLE GRINDERSYSTEMRSHA SUBMERSIBLE GRINDER SYSTEMMG SERIES CENTRIfUGAL AUToMATIC GRINDER PUMP• Heads to 138 feet and flows of 70 GPM.• Recessed impeller provides steep non-overloading operating curve and reduces radial bearing loads, increasing bearing life.• Oil-filled motor for maximum heat dissipation and constant bearing lubrication.• High torque capacitor starts single phase motor for assured starting under heavy load. No external capacitor needed.• On-winding current and temperature-sensitive overload.• Shredding ring and grinder impeller are replaceable without dismantling pump or motor.MGPD SERIES SEMI-PoSITIVE DISPLACEMENT AUToMATIC GRINDER PUMP• Heads to 173 feet and flows to 19 GPM.• Buna-N pump stator for long life• Oil-filled motor for maximum heat dissipation and constant bearing lubrication.• High torque capacitor starts single phase motor for assured starting under heavy load. No external capacitor needed.• On-winding current and temperature-sensitive overload.• Grinding cutter and shredding ring are replaceable without dismantling pump or motor.Available in depths from 4' to 8'Optional Electrical Junction Box (not shown)Preassembled Discharge PipingHigh Level Alarm Float SwitchSubmersible Centrifugal or Semi-Positive Displacement Grinder Pump Wide Angle Float Switch for Pump Operation2EEFFDDBABACCfIBERGLASS BASIN CHoooSE YoUR PUMPSHA CoNTRoL PANELCoNTRoL PANEL SPECIfICATIoNSPUMP PERfoRMANCE Overall Dimensions 9.5" x 11.75" x 7.25" Enclosure Nema 4X Polycarbonate with Mounting Feet Alarm Piezo 95 db with “Touch to Silence” circuitry Flashing LED Alarm Light Weight 6 lbs.

High torque oil-filled motor conducts heat and lubricates bearings. Class F VFD/continuous duty rated.Cable entry system provides double seal protection. Cable jacket sealed by compression fitting. Individual wires sealed by potting epoxy. Power cord can be replaced without disturbing motor.Overload-heat sensor protects motor from burn-out due to excessive heat from any overload condition. Automatically resets when motor has cooled.Shaft seal single carbon and ceramic faced seal. Oil lubricated.Volute case cast iron, 11/4" vertical, flanged discharge.The shaft and all fasteners are made from corrosion resistant stainless steel.Grinder impeller and shredding ring are replaceable without dismantling pump. Constructed of 440 SST hardened to 56-60 Rockwell.Engineered thermoplastic recessed impeller handles ground slurry without clogging or binding. Provides unobstructed flow passage. Reduces radial loads. pump-out vanes help keep trash from seal, reduces pressure at seal face.
