“Simply the Best  Non-metallic Magnetic Drive Pump Available Anywhere!” Wolfgang Renner, founder, Renner Pumps	Applications Absolutely Leak Free Proven Reliability and Durability Exceptionally Quiet and Vibration Free Unsurpassed Quality Withstands Common Upset Conditions
Applications Wherever you need absolutely leak free , corrosion resistant pump performance:- Chemical plants Pharmaceutical plants Water and wastewater treatment plants Electronics manufacturing OEM’s Our range offers the perfect pump for:- Acid and alkaline solutions High purity water Water treatment chemicals Electroplating chemicals Photographic chemicals Electronics cooling 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
