Data needed for ordering
Where: Q₁, Q₂ and Q₃ – volume flows in m³/s or m³/h; ρ₁, ρ₂, ρ₃ – densities in kg/m³; p₁, p₂ and p₃ – pressures in bar, preferably bar (abs). Index 1 denotes the motive fluid at the ejector inlet, index 2 the suction fluid at the inlet and index 3 the mixture of motive and suction fluid at the outlet.
When ordering an ejector please state the following data:
- densities ρ₁ and ρ₂ in kg/m³;
- mass flows m₁ and m₂ or at least one of them in kg/s (kg/h), or volume flows Q₁ and Q₂ or at least one of them in m³/s (m³/h);
- two of the three pressures p₁, p₂ and p₃ in bar or bar (abs);
- if all three pressures are given, only one mass or volume flow may be specified.

Ejectors are manufactured with flanges, pipe threads and hose connections for rubber and plastic hoses.
