Absolutely Leak Free

• Care to avoid leaks from secondary sources
• Casing flange fasteners precision tightened
• True Union Coupling for pump inlet and outlet
• Hand tightened and uses an o’ring to avoid leaking from under or over compression
  
  

Proven Reliability and Durability

• Twenty plus years of experience
• Well over 80,000 units sold
• Europe’s best selling magnetic drive pump 
• 100% of the units are performance tested
  
  

Exceptionally Quiet and Vibration Free

• All components have precision tolerances
• Designs (larger than BTMD10) are hydraulically balanced
• Motors are precision balanced
• Bearings operate on a thermally stable hydrodynamic film
• Result is a pump that you can hardly hear when in operation!
• Quietest pump in its class.
  
  

Benefits:

• Quieter production area
• Longer lasting pumps
  
  

Unsurpassed Quality

• Every pump performance tested prior to shipment
• Testing includes momentum reversal to simulate worst case field conditions
• Every pump performance tested prior to shipment
• Performance test covers ten points over the full curve
• Testing includes momentum reversal to simulate worst case field conditions
  
  

Withstands Common Upset Conditions Run Dry

• Ceramic bearings will tolerate run dry for short periods after the loss of flow
• Teflon impregnated graphite bearings will tolerate slightly longer periods of run dry after loss of flow
  
  

De-Coupling

• De-coupling can result in permanent loss of magnetic strength in the magnets
• BTMD Series motors have a built in service factor of 1.25 to prevent decoupling caused by overloads
  
  

Thrust Reversal

• Changes in conditions may cause sudden changes in thrust load
• Uncontrolled thrust swings can cause internal damage and de-coupling
• All BTMD Series pumps have thrust bearings to control thrust at all times
