  • White paper - Chemical feed control

    The controls, alarms and external contacts are shown on the drawings. As the amount of chemical needed to neutralize the wastewater varies exponentially from neutral pH 7, special consideration must be given to control overshooting the pH. Chemicals, especially viscous caustic soda, must be fully mixed in the compartment before more is added. Rather than modulating the pump settings, the pump is ...

  • What is a Syringe Pump?

    A syringe pump is a type of infusion pump originally developed to help administer drugs to patients in a controlled manner. Early attempts to construct infusion pumps were made in the 19th century. However, the first infusion device was introduced in the 1950s to be used in chemotherapy. In the 1970s, the development of ambulatory infusion technology enabled the pumps to be used in research; ...

  • Understanding Pump Cavitation

    Cavitation is a major problem in the chemical industry because it affects a basic tool, the centrifugal pump. A sudden increase in the velocity of the pumped liquid reduces the inlet pressure, sometimes below the vapor pressure.The result is formation of gas and bubbles. Detecting the signs of cavitation, and correctly identifying and understanding the type of cavitation present, can help an ...
