Triplex Process Diaphragm Pump

LEWA triplex is the most compact process diaphragm pump in the world for high-pressure processes. Its space and weight-saving monoblock design also makes it suitable for any application with extremely small installation space.

  • Maximum flow rate 180m³/hr per pump
  • Maximum discharge pressure 1,200bar

Advantages:

  • Solid, durable and long-lived total design based on a one-part crankcase and double bearing crankshaft
  • Extremely smooth running and low pulsations flow due to even phasing of pistons
  • Integrated reduction gear unit and vertical flange motor
  • Lowest possible lifetime costs due to high energy efficiency, low maintenance costs and extremely long service life of the sandwich diaphragm
  • Unique suction lift capability (absolute suction pressure down to 0.1 bar abs is possible) for a variety of reliable installation options and lower system costs
  • Absolutely reliable start-up of the pumps from any operating state
  • Hermetically tight
  • Suitable for nearly any liquid, even for hazardous, flammable, toxic, abrasive, viscous, polluting fluids
  • Patented sandwich diaphragm with LEWA DPS (Diaphragm Protection System) and diaphragm monitoring
  • Integrated pressure relief valve
  • Maximum reliability and availability even after operating errors or upset conditions (e.g., high suction pressure, blocked discharge or suction line)
  • Compliance with globally valid standards such as VDMA 24284, 24286-10, API 675
