HPX-MagAPI 685 Pump
API 685 – HPX Mag Drive
• Desio, Italy Build• Test R&D pump – Successful!!• (2) 1.5HPX13-Mag – recently sold (Aug
2016) to eastern Europe refinery• New RFQ’s Welcome!
Mag-Drive Protection Options
• Pump Power Monitor• Temperature probe• Fiberoptic leak protection
Power Protection Monitor
• For overload protection– Excessive wear or
rubbing– Bearing failure– Decoupled magnets– Motor overload
Power Protection Monitor
• For under-load protection– Dry run– Blocked suction– Decoupled magnets– Failed spacer element– Air entrainment– Minimum flow– Loss of prime
Temperature Probe (RTD or Type J)• Shell Probe
– Probe in constant contact with exterior surface of the shell– Detects temperature increases that indicate
• Pump running dry• Recirculation path blocked
• Process Probe– Probe in a thermowell located in the bearing holder– Thermocouple contacts the fluid as it leaves the shell– Detects unusual temperature increase
• Responds quicker than shell probe but does not detect dry run• Practical for monitoring temperature sensitive liquids
– High vapor pressure– Polymer that polymerizes at elevated temperature
Fiberoptic Leak Detection
• Located on bearing housing• Sensor can be located in hazardous area
with electrical relays in safe area• P/N: AY56318A-VEND
Typical Applications & Services
• Applications– Dosing– Metal finishing - pickling– Etching and plating– Tank car loading and unloading– Scrubber systems
– Chemical processing – Mining/Ore Processing– Reactor feed– Pure Water, RO & DI– Chlor-alkali– Waste treatment chemicals
• Services– Acids– Ammonia– Benzene– Caustic soda– Chlorine– Corrosives– Ferric chloride– Fertilizers
– Hydrogen peroxide– Methyl ethyl ketone– Oleum– Pharmaceuticals– Pesticides, Insecticides, Herbicides– Sodium hypochlorite– Solvent– Sulfuric acid
