Pump Assemblies

Foam Packaging Pump

Application:

  • Spray and bag foam packaging

Requirements:

  • Fit through opening in a standard 55-gallon drum
  • Pump precise amounts of fluid with little pump to pump variation
  • High tolerance for solvents and high viscosity fluids
  • 300 to 1000-psig operation at relatively slow speeds (1000 rpm)
  • High reliability and long life

Solution:

  • Nichols Portland custom design, including performance and endurance testing.
  • Extremely tight positional and size tolerances enable precise flow output with little pump to pump variation.
  • Application specific gerotor purposely designed for low rolling stresses and long life.
  • Entire pump has surface treatments which support long life and robust journal bearings.

Binary Lube Pump

Application:

  • Lubrication of Hybrid Transmission

Requirements:

  • Two independent pumping loops on one common drive shaft
  • Unit 1 = High flow and low pressure
  • Unit 2 = Low flow and high pressure
  • Validation to demanding OEM specifications (long-life, wide temperature range, rapid pressure changes, other)

Solution:

  • Two gerotors, phased to reduce peak loading on shaft
  • Cast iron housing to minimize impact of temperature on pump performance

Lube and Scavenge Pump

Application:

  • High Performance OEM Automotive

Requirements:

  • Scavenge oil from multiple engine locations and deposit in remote tank
  • Pull oil from remote tank to lubricate engine
  • High performance OEM operating environment (thermal, speed, vibration, other)
  • Validate design through extensive testing

Solution:

  • Four gerotors, one lube and three scavenge gears pulling from four locations
  • Integrated pressure regulating valve, oil cooler, cooler bypass valve and filter
  • Extensive validation testing (steady state and cyclic endurance, cold and hot testing, contamination resistance, 10-million cycle spring and valve testing, etc.)

  • Tolerance for very low viscosity fluids (R134a, R245fa, other)
  • 0.25, 0.5 and 2.6-gpm and up to 50-psig

Solution:

  • Stainless steel spur gears
  • Coated pump surfaces
  • Brushless DC motor and controller
  • Variable speed control
