vertical turbine pumps

Hydroflo provides investment cast stainless steel impellers in all of their vertical and submersible turbines to 9000 GPM. The stainless provides all customers with better abrasive and chlorine resistance in their pumps. Gold, copper, zinc, and coal mining companies are using Hydroflo abrasive duty pumps for their dewatering needs. Their pumps are built with standard stainless steel impellers, vesconite bearings, and 17-4PH shafting, allow the mines longer life cycles and less down time. Construction using all 316 stainless steel enables us to meet all of their engineering requirements for corrosive resistance.

Hydroflo Pumps has provided over 140,000 GPM of cooling capacity to one of the largest nuclear plants in the USA. With individual pump capacities over 30,000 gallons per minute, Hydroflo has provided many industrial and municipal cooling tower projects. Steel mills to classrooms, our engineers have met the pumping requirements.

LOST WAX INVESTMENT CAST STAINLESS STEEL

Lost wax investment castings are superior to all other impeller castings.

  1. The smoothness of the casting increases efficiencies.
  2. The wax is injected into a stainless pattern, thus a perfect mold each injection.
  3. Sand castings will have core shifts, increased void areas, and rough surfaces.

Stainless is superior to bronze in all engineering applications.

  1. Strength and Hardness are considered two of the most important physical properties when choosing pump impeller material. Stainless impellers have a Brinell Hardness Range of 212-280, the best choices in bronze are 60-159.Tensile Strength for stainless is 80,000-135,000 PSI, again bronze is only 26,000- 85,000 PSI
  2. Stainless steel is better against abrasion and corrosion. Stainless is the choice in high chlorine concentrations, salt water aplications, and in low PH water.
  3. Stainless should always be chosen for applications where the presence of sand or abrasion particles are known to be in the water.

DUCTILE IRON DISCHARGE HEADS

  • Ductile Iron is a superior casting material over Class 30, Cast Iron.
  • Ductile Iron Tensile Strength: 65,000 lbs
  • Class 30 Cast Iron Tensile Strength: 30,000 lbs
  • Because of this strength, Hydroflo Ductile Iron discharge heads can handle higher pressures and more hang weight.
  • The porosity in Ductile Iron is much smaller, thus providing a better corrosive resistance than Cast Iron.
  • Cast Iron is a brittle casting. Ductile Iron has a stretch factor and will not break or crack as easy as Cast Iron.
  • Hydroflo provides 4”, 6”, 8” and 10” Ductile Iron discharge heads with identical centerlines.This allows different size pumps to connect into the same height header pipe.
  • Hydroflo has a 4” and 6” Ductile Iron discharge heads with a 300lb ANSI discharge flange.
