Features

• Unbalanced Air Valve Eliminates Stalling -
  Start it up, shut it down - no matter how often or how long, the IR Diaphragm Pump will start pumping every time.
• No Lubrication Required -
  One less maintenance detail to log. No oil droplets to contaminate your process or work site. And, the IR Diaphragm is more forgiving in dirty air service.
• Pumping Efficiency Remains Constant -
  Since IR Diaphragm Pumps contain no rotors, gears, vanes or pistons to wear out - there is no gradual decline in pump performance. And the IR "Unstallable" air valve uses less power to operate than competitive brands.
• No Foaming or Shearing of Material -
  Process fluids enter and exit the IR Diaphragm Pump unchanged.
• Variable Flow Rates -
  By simply adjusting air pressure to the pump, or restricting the discharge line, you have better, more precise control over your pumps flow rate - without pump damage.
• Positive Priming Provides Easy Start-Ups -
  Internal pump fluid check valves are located close to the diaphragm chambers - assuring positive self-priming - even from dry start.
• Runs Dry Without Damage -
  Because there are no sliding or close-fitting parts at risk - the IR Diaphragm Pump can run dry without damage.
• Lightweight and Portable -
  Most IR Diaphragm Pumps can be carried from job to job with ease.
• No Complex Controls -
  Unlike electric pumps, IR Diaphragm Pumps contain no wires, circuits, fuses or bypass controls to burn out and replace.
