Positive displacement pumps li itšetlehile ka liphetoho tsa molumo nako le nako tse hlahisoang ho sebetsa ha molumo oa metsi le ho ntša metsi, ha molumo oa mosebetsi o ntse o eketseha, mokelikeli oa pompo o monyang;ha e fokotseha, pompo e ntša metsi.Litšobotsi tsa kinematic ho latela mosebetsi oa mofuta ona Li ka lehlakoreng le leng li arotsoe ka:
1. Mokhoa oa ho sebetsa oa pompo o khutlisetsang morao bakeng sa motsamao o phetoang.Mofuta ona oa pompo ke pompo ea piston, piston, chestnut ea diaphragm joalo-joalo.
2.Lisebelisoa tsa mosebetsi oa lipompo tsa Rotary bakeng sa ho potoloha ha axis e tsitsitseng.Mofuta ona oa pompo ke pompo ea gear, pompo ea screw,indasteri ea pompo ea lehlohlojanelipompo tse thellang.

Li-chestnut tsa Vane li itšetleha ka potoloho e le 'ngoe kapa tse' maloa tse phahameng ka lebelo la impeller ho khothaletsa phallo ea mokelikeli, ho fihlela lipalangoang tsa metsi.Ho latela mokelikeli o tseleng ea phallo ea pompo ea vane pompo e arotsoe ka:
1.Pump fluid e phallang ka mokhoa o feteletseng ka pompong, matla a sutumelletsang metsi a phallang ha matla a centrifugal a hlahisoang ke ho potoloha ha impeller.
(2) Axial fluid e phalla ka axially ka pompo, matla a sutumelletsang metsi a phallang axial thrust a hlahisoang ha ho potoloha.
3. Mokelikeli oa pompo o phallang ka har'a pompo o phalla ho ea pompong ea pompo ka lehlakoreng le itseng, matla a sutumelletsang phallo ea metsi ha matla a centrifugal a hlahisoang ke ho potoloha ha impeller le axial thrust force.

1, ho phalla ha Q
Phallo ke palo ea pompo ea lehlohlojane e mokelikeli nakong ea ho fana ka yuniti (bolumo kapa boleng).
Phallo ea molumo le Q e boletse, yuniti ke: m3/s, m3/h, l/s joalo-joalo.
Phallo ea boima le Qm e boletse, yuniti ke: t/h, kg/s.
Kamano pakeng tsa phallo ea boima le phallo ea molumo bakeng sa:

2, hlooho ea H
The head is the unit weight of the liquid gravel pompo pumping imported from the gravel pompo (inlet flange gravel pump) to the gravel at outlet of the pompo (pompo outlet flange gravel) energy increment.Matla a sebetsang ke mokelikeli oa Newtonian o fumanoang ka pompo ea lehlohlojane.Yuniti ke N?m/N=m, bolelele ba mokelikeli o pompang metsi kholomong ea lehlohlojane, mekhoa, e bitsoang M.
