When sending enquery, please give us all available information (above parameters), in order for us to calculate and offer ejector according to your requirements!
Ejector defining parameters are given in table below and are shown on drawing of typical water ejector installation: 
|
Parameter |
Unit | Name | Note |
| Qs | m3/h | Suction capacity | Capacity that ejector will draw. |
| Hs | m | Suction lift / head | Total suction height from which ejector will draw, which includes geodetic height and head drop due to resistance in suction piepline. In ejector installation this value is usually negative (ejector must create vacuum to suck in medium).
Hs = Hs res + Hs geodetic Note that Hs in theory cannot be more than -10 m (-8 m in reality). |
| Hd | m | Delivery head | DDelivery head is head to which ejector will deliver, and it includes geodetic delivery height (measured from ejector discharge flange axis) and head due to resistance in delivery pipeline.
Hd = Hd res + Hd geodetic |
| Ht | m | Total head |
Total head or total differential head is combined diference between suction and delivery head Ht = Hd + Hs |
| Qd | m3/h | Driving medium consumption | This is capacity of driving medium (usually water) required to create necessary suction capacity Qs and head Hs, as defined above. |
| Pd | bar | Avialabe pressure of driving medium | This is pressure of driving medium (usually water) at ejector inlet, required to create necessary suction capacity Qs and head Ht, as defined above. |
