ITT has enhanced its Goulds Pumps line of stainless steel, vertical multi-stage pumps with the introduction of new e-SV™ models.  Featuring an innovative hydraulic design and efficient motor that lowers lifecycle costs and increases energy savings, the pumps are suited for a wide variety of commercial and industrial applications.

From ITT, the Goulds Pumps line of stainless steel, vertical multi-stage pumps now includes e-SV™ models.

The new hydraulic design also provides superior NPSHR levels. Maintenance time is also significantly reduced because the new design has eliminated the need to remove the motor while work is performed.  The mechanical seal is also replaceable without the need for pump disassembly, and the “O” ring seat is designed to allow easy disassembly of the outer sleeve.

All stainless steel construction and NSF certification allow the e-SV pump to meet municipalities’ requirements for pure water while providing superior corrosion resistance and easy installation.

Other features of the new e-SV pump include:

  • Superior pump efficiency that allows greater energy savings with lower horsepower motors. And when combined with ITT’s HydroVar® controller, the e-SV pump offers an additional 10% savings potential from the previous generation pump, and a “green” system solution;
  • E-SV pump’s hydraulic design results in lower NPSHR, reducing piping and elevation expenses by over 20%;
  • Robust design methods targeting an MTBF of 20,000 hours;
  • Expanded pump portfolio allowing pump selection aligned with optimum duty point for greater cost efficiency;
  • Impeller axial thrust is minimized, resulting in longer bearing life and use of standard motor configurations; and
  • Patented i-ALERT™ monitor continually measures vibration to support optimum performance. Available on pumps 10HP and above.

The e-SV pump can be used for many applications, including:

  • Water supply and pressure boosting;
  • Water treatment;
  • Light industry;
  • Irrigation and farming; and
  • Heating, ventilation and air conditioning.
