AC Motors – Hermetic

Peerless Electric Canned Motors have made a significant contribution to the ever growing popularity of canned pumps. This type of pump eliminates the nuisance of dynamic shaft seals and stuffing boxes.

Product Inquiry Form

Our hermetically sealed motors provide silent, vibration free operation and eliminate many conventional pump limitations such as:
  • Mechanical Seal Leakage resulting in loss of solution, system pressure or vacuum

  • Corrosive Limitations

  • Excessive Floor Space

  • Excessive Maintenance

  • High Pressure Limitations

  • Alignment problems between motor stuffing box and pump

Advantages:

  • Hermetically sealed enclosure of rotor area obtained without use of static O-rings, gaskets, or epoxy

  • Standard units can handle liquid temperatures up to 400°F and system pressures to 600 PSI

  • Fully welded joint construction. All welds gas tested to an allowable rate of .0005 ounces / year of standard air

  • Self-alignment automatic as bearings are lubricated by the solution being pumped to keep the rotor in perfect alignment

  • Reduced noise levels

  • Required floor space approximately one-half of that needed for a conventional pump

  • Squirrel cage rotor fully encased in stainless steel

  • Back-withdrawal of stator and frame permits winding replacement without opening of pumping system

  • Our varnish and encapsulated stator windings offer maximum protection against high humidity environment

  • UL and RoHS Compliant

  • Product markings are available

Peerless AC Hermetic Motors are application engineered to meet your specific needs.

Industrial Applications

  • Chemical Processing
