ROTO-JET High Pressure Pitot Tube Pumps

Roto-Jet pumps meet the demands of low-flow, high-head applications.  Roto-Jet high pressure pumps add energy to the fluid via the rotor, and the stationary pitot tube converts the fluid velocity energy into static pressure.  The advantages over a standard centrifugal pump include:

  • No external lube system required 
  • No wear rings or close running clearances  
  • Pulsation free flow over the entire head-flow curve 
  • Reduced life cycle cost by optimizing hydraulic efficiency 
  • Process seals exposed only to suction pressure for maximum seal life 
  • High heads achieved in a single stage at low operating speeds compared to other low-flow, high-head pumps
  • Designed and manufactured to achieve a broad operating range without creating damaging hydraulic forces in the pump
  • Stationary in the 12 o’clock position to facilitate venting of the rotor during start-up.
  • Max Capacity: 750 gpm
  • Max Head: 5,200'
  • Max Pressure: 2,250 psi
  • Max Temp: 550°F
  • Max Speed: 6,321 rpm
  • API Options
