ANSI PUMPS REDEFINED

Seal-less – Revolutionary Dynapump LE Canned Motor Pumps

Now you can get engineered, canned motor pumps at a price comparable to mechanical seal pumps. Dynapump LE Canned Motor Pumps are environmentally friendly. You already know about the benefits of canned motor technology. There's no reason to spec anything else for your ANSI pump applications.

  • Environmentally friendly - It's the greenest pump you can buy – no leaks...ever!
  • Seal-less
  • Leakproof - 100% leak-free, double containment surpasses mag drive pumps
  • Innovative design keeps the bearings running cooler – greatly increasing service interval time
  • Quick availability - Stock to 3 weeks for delivery

Dynapump LE Canned Motor Pumps:

  • Totally eliminate hazardous emissions & costly leaks
  • Totally eliminate leaking mechanical seals, associated maintenance & costly downtime
  • Totally eliminate single containment mag drives
  • Totally eliminate mag drive high cost

FEATURES

  • ANSI/ASME B73.3M Compliant - No modifications necessary to the piping, base plate or electrical switchgear when replacing your existing ANSI pump.
  • Bearing Wear Detector - Powerful diagnostic tool for monitoring the condition of the pump. Allows users to perform simple parts replacement well before significant damage occurs.
  • Positive Secondary Containment - Contains the process fluid within the pump.
  • Low Cost - Price is comparable to a single mechanical sealed ANSI pump.
  • 316SS Construction with Hastelloy C Liners - Offers excellent corrosion resistance for the majority of liquids.
  • Carbon Graphite Bearings - Excellent chemical resistance and very forgiving bearings when process upsets occur.
  • Field Replaceable Wear Parts - Allows users to perform most repairs in-house.
  • Automatic Thrust Balance - Eliminates contact between rotating and stationary elements. The single rotating assembly "floats" in the liquid.
  • Best in Class Efficiency - Low & high flow impeller designs for each size.

Dynapump LE Series Bearing Wear Monitor

BEARING WEAR MONITOR

A standard feature supplied on all Dynapump LE pumps is Teikoku USA's patented bearing wear monitor, the Teikoku Rotary Guardian or "TRG". The TRG takes the mystery out of pump reliability by continuously monitoring the critical running clearances between the rotating and stationary components.

The bearing wear monitor is mounted on the Dynapump LE electrical junction box as standard, and remote output options are also available. This information allows the user to perform planned maintenance and replacement of simple wear parts long before a costly failure occurs.
