Pentair Berkeley 7TMH Submersible Turbine Pumps

The 7TMH pump series features abrasion and corrosion resistant materials for maximum performance and longevity under the toughest operating conditions, and delivers industry-leading efficiencies and head per stage.

  • Discharge Ductile iron ASTM 536-84: Threaded with large wrench flats and sized for the pumps flow range
  • Upthrust nut/screw: Factory pre-set upthrust screw is retained by a stainless steel locknut, providing maximum upthrust protection.
  • Discharge bearing - Vesconite: Low friction, no water swell, long life. Specific for water-immersed applications, clean or dirty
  • Shaft - 416 stainless steel: Precision ground and polished for reduced running friction and increased service life
  • Impeller - 304 stainless steel, investment cast: Smooth and efficient performance, long life
  • Bowls - Class 30 cast iron: Heavy-walled construction incorporates precision hydraulic design for maximum efficiency and performance. Coated internal passageways on the 7TMH series increases overall pump efficiency and performance.
  • Isolator bearings - neoprene: Unique design channels abrasives away from the stainless steel shaft bearing journal.
  • Lead guard - 302 stainless steel: Protects the motor leads across the full length of the pump (not shown)
  • Suction bracket - Ductile iron: ASTM 536-84 Available with either 6 or 8 intake adapters. Designed to effectively divert debris away from the spline engagement area, maximizing durability.
  • Suction screen 304 stainless steel: Form fitted, provides corrosion resistance, and prevents particulates larger than .19 (4.8 mm) from entering the pump (not shown).
  • Motor coupling - 416 stainless steel: Fully machined for positive fit; highly corrosion resistant
