Nota:

- Pn: presiunea nominala

- Pmax: presiunea maxima la care poate lucra pompa intermitent (max. 20 s); presiunea medie nu va depasi presiunea nominala.

- Varfurile de presiune, de comutare, pot depasi presiunea maxima cu 20 bar.

- Randamentele volumice r|vn se garanteaza in conditii nominale si la o vascozitate a uleiului de 30...40 mm²/s.

- Caracteristicile de mai sus sunt valabile si pentru pompele duble (la fiecare treapta in parte).

- La cerere se pot construi pompe cu alte volume geometrice sau cu alte configuratii.

- Pentru n>1500 rot/min, P<1500000 / (Vg x nef)

- Functionarea pompelor la turatii ridicate, fara cavitatie, este posibila numai cu o aspiratie suficient de larga.

Note:

- Pn: nominal pressure

- Pmax: maximum pressure at witch the pumps can intermittently work (max. 20 s); average pressure should be lower than Pn.

- Pressure peaks, in comutation can be 20 bar higher as Pmax.

- Volumetric efficiency r|vn is guaranted in nominal conditions and viscosity 30...40 mm²/s.

- The characteristics mentioned above are valid also for double pumps (for every stage).

-At request, can be manufactured pumps with other displacements and configurations

- For n>1500 rev/min, P<1500000 / (Vg x nef)

- Functioning at high speed, without cavitation, it is possible only with an enough large inlet.
