  • Torque Sensor Application - Constant Flow Pump
    In the constant flow pump, a stepping / stepper motor is used to create a pumping function and allow fluid to flow. A reaction torque sensor attached to the back end of the motor monitors the required torque and can relate the changes in torque to the flow rate or alarm the operator when the torque
  • Pump Basics
    The most important characteristic of a centrifugal pump is that of converting energy from a source of motion (the motor) first into speed (or kinetic energy) and then into pressure energy. A pump's role is in fact to confer energy to the pumped liquid (energy later transformed into flow rate
  • Liquid Pumps-Viscosity Handling Characteristics
    regardless of changes in shear rate or agitation. As pump speed increases, flow increases proportionately. Liquids displaying Newtonian behavior include water, mineral oils, syrup, hydrocarbons, and resins.
  • Key Considerations for Selecting a Medical Pump
    Newcomers to medical device design may think that pressure and flow rate are sufficient parameters to consider when it comes to selecting a pump. While this may be the case in some industrial applications, medical device requirements are a bit more demanding. A thorough review of the selection
  • Monitor Your Pump for Process Efficiency
    . These efforts will improve end-product or batch quality, cut the material costs, eliminate waste and reduce maintenance costs. Taking good care of your pump always delivers a positive payback and there are some simple strategies that can be employed-starting with an analysis of process media flow rates
  • Water Accountability - Portable Monitoring Instruments Solve Flow Rate Mystery
    With flows exceeding permit limits, the Village of Glen Walter uses Greyline Stingray Level-Velocity Loggers and discovers household sump pump connections to the municipal connection system.
  • Flow rate more than doubled.
    Buttermilk, which is highly popular in Ireland for baking scones and pancakes, is particularly sensitive due to its microbiological structure. Tricky conditions for profitable production are no problem thanks to SEEPEX's pumping solutions for the food industry.
  • Helical gear pump selection calculations and installation notes
    Calculate fluid velocity, delivered flow rate, absorbed torque and power for low noise and low pulsation helical gear pumps.
  • Pick The Right VFD For Progressive Cavity Pumps
    One of the greatest advantages of a progressive cavity (PC) pump is that its flow rate is determined solely from the pump speed. These pumps are unique because their starting torque is often greater than the operating torque during operation, but this characteristic creates a challenge when using
  • Seal-less Regenerative Turbine Vane Pump Resolves Volatile Situation (World Pumps : June 1999)
    to be capable of generating flow rates of only 2 - 3 gpm.
  • Topsflo - Forging Ahead to Build a Century-old Brand of Micro Pump
    For production enterprises, brand confidence comes from the persistence of quality. Based on the brushless DC pump industry, TOPSFLO will develop bigger flow rate brushless DC water pump products to match heating equipment while ensuring stable and reliable quality.
  • Flow Velocity in Plastic Piping Systems
    be hundreds of pounds per square inch, is often more than enough to cause severe damage to plastic piping systems that are often rated for 150 psi. This shock pressure can be created in a piping system when a valve in the system is opened or closed quickly, a pump is started or stopped, or when a pump
  • Magnetic Drive Sealless Pump Smooths Caustic Unloading Operation (Chemical Processing : May 1990)
    The Ethyl Corp. Petroleum Additives Div., Suaget, Ill. Plant receives 50% caustic (sodium hydroxide) raw material by tank trucks. The caustic was formerly unloaded from truck to storage tank by using nitrogen to pressurize the tank truck, providing a flow rate of 40 gpm. Their objective
  • Part II: Organoclays Improve Performance of Pump and Treat Remediation Systems
    someone installs a vessel with 1,000 lb of granular activated carbon (GAC) to remove 3 ppm of benzene at a water flow rate of 100 gallons per minute (gpm). But the 1 ppm of oil that is present is not taken into account since it is perceived to make little difference to the effectiveness of the process.
  • Flowmeter Troubleshooting
    An Ontario municipality deploys Portable flowmeters to solve flow rate discrepancies between pump station effluent and lagoon influent flowmeters.
  • A Primer on Pressure Drop
    All of Lytron's thermal systems are designed for maximum performance at a specific flow rate. Less flow will cause the system to under perform. Flow rate is dependent upon the system's pressure drop and the pump's head pressure. This applications note reviews how to determine your pressure drop
