  • Gear Pump Selection Information
    General pump selection: Applicable to the handling of all reasonably clean liquids, preferably having some lubricating value. Also suitable for handling non-lubricating liquids under limited conditions of operation with grease fittings or carbon bearings. Gear Pump, Liquid Pumps - Clark Solutions...
  • Protect Your Pump and Keep It Longer
    affect pumps are wet/dry conditions and flow disturbances-both of which are preventable. Nothing can damage a liquid pump faster than the build-up of heat from dry running conditions, which occurs when liquid stops flowing into the line or the pump. When the liquid isn't there to provide cooling...

For pump. ratings of 3,500 hp or less, steam turbines are usually single-stage. Condensing Cycle...
  • Eleven Tips for Electric Diaphragm Pump Selection
    ultimately will cause less stress on the pump and other components in the system, consume less energy, create less heat, and generate less noise and vibration. 8. Start Against a Load. Most pumps are not designed to start (or restart) against a load. Modifications to the pump can allow for starting...

  • Sizing and Selecting Metering Pumps Planning a Metering Pump Installation (.pdf)
    Identify the required capacity in terms of flow rate and discharge pressure. Do not oversize a metering pump. A metering pump should be sized so the maximum expected flow rate is 85% to 90% of the pump capacity. This leaves additional capacity if needed. The minimum capacity should never be less...
