- 12. Pressure? Discharge Pressure 16 Bar, 15 Bar, 8 Bar, 6 Bar, or 4 Bar are just numbers on the Brochure. The reality is different! How about; • Line Losses • Pulsation Losses • Static Losses The calculated outcome of the line losses, pulsation losses, and static losses will influence the functionality of the pump tremendously! Rubio Fluid Dynamics SL - Copyright 2018
- 13. Pressure? Inlet Pressure up to 9,5 meter suction lift. This includes static height, line losses, and pulsation losses. OK nice to know, but it is not a Vacuum Hose! How about; • Reduction of Pump Speed • Hose Life reduction • Use of Vacuum Assist The Inlet Pressure is the most important influencer on the pump performance. Not knowing the can result in very costly mistakes! Rubio Fluid Dynamics SL - Copyright 2018

- 15. Continuous or Intermittent Duty? The operating area is not a constant and changing depending on; • Product Temperature • Ambient Temperature • Pump Speed • Discharge Pressure • Lubrication / Coolant Fluid It is about the hose temperature, but how hot does the Hose get? Cool-down Time ? Rubio Fluid Dynamics SL - Copyright 2018

- 17. Product Temperature? The normal rated product temperature is between 40°C and 80°C. The operating area is influenced by pump speed and discharge pressure.
- 18. Product Temperature? The normal rated product temperature is between 40°C and 80°C. The operating area is influenced by pump speed and discharge pressure. 40°C - 16 Bar Operating Area!
- 19. Product Temperature? The normal rated product temperature is between 40°C and 80°C. The operating area is influenced by pump speed and discharge pressure. 80°C - 16 Bar Operating Area! Also the Intermittent Area is reduced!

- 22. Calculation? • Input • Fluid (type, density, viscosity, temperature, and vapor pressure) • Flow required (minimum and maximum) • Solids information (hard/soft, particle size, required velocity, and weight %) • Line dimensions (length, diameter, and static height) • Highest ambient temperature • Altitude • Dampener and type of dampener (reduction of pulse?) Rubio Fluid Dynamics SL - Copyright 2018
- 23. Calculation? • Output • Selected pump size • Curve for inlet- and discharge-side (operating area, pulsation, pressure, power usage, continues and intermittent area) • Power requirements (minimum and maximum operating) • Gearbox selection • Recommended hose and insert materials • Estimated hose life Rubio Fluid Dynamics SL - Copyright 2018

- 25. Installation? • Best Installation Practice for Peristaltic Pumps • Pump Port direction (be aware of solids and cleaning) • Pulsation Dampener (functionality - sizing and installation details) • Vacuum Assist (be aware – it’s a hose killer) • Frequency Inverter (maximum speed protection) • Reverse Operation (be aware of pulsation – discharge becomes suction) Rubio Fluid Dynamics SL - Copyright 2018
