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
