  • Transferring and Metering Liquids with High-Speed Diaphragm Pumps
    of the Christian calendar, Archimedes had invented his screw pump, and the Greeks used piston pumps for handling water. With the alchemists, metering liquids became increasingly important.Today the liquid pump industry has developed to become a many-faceted branch of mechanical engineering, and offers
  • New Technology for Metering Fluids in Medical Devices
    10:1to as high as 1000:1 on some pump models. Accuracy, repeatability, and linearity across the turndown range are the features that differentiate a metering pump from a typical positive displacement pump. Positive displacement metering pumps are normally classified as rotary or reciprocating. Rotary
  • Micro-Dispensing Liquid Pump
    New liquid dispensing pump technology that uses a solenoid rather than a dc motor precisely delivers fluids up to 20 times per second for accurate metering applications. The design of the pump also offers high reliability, normally an issue with solenoid-operated pumps and valves
  • Five Questions to Ask when Specifying Fluid-Handling Pumps
    be used with a variety of motor types. Depending on the type of drive used, diaphragm liquid pumps can be categorized as high-speed and low-speed pumps. Low-speed diaphragm liquid pumps operate at speeds up to about 300 strokes/min, making these pumps especially suitable for metering. The flow rate
  • Versatile Solutions for Micro-Dispensing
    for virtually every requirement. Introduction. Diaphragm metering pumps offer several major advantages over rival types of pumps. For example, they are self-priming and safe to run dry (i.e. they can also pump air). Diaphragm pumps are ideally suited for volatile media and crystallizing chemical

A relay in the controller closes the supply power to the pump or. valve, and opens again once the set point pH or ORP value has been reached. In rare cases, more
