8. Les bombes de pistons estan formades per un conjunt de petits pistons que van pujant i baixant de forma alternativa d'una manera semblant als pistons d'un motor a partir d'un moviment rotatiu de l'eix. Aquestes bombes disposen de diversos conjunts pistó-cilindre de manera que mentre uns pistons estan aspirant líquid, altres ho estan impulsant, aconseguint així un flux menys polsant, sent més continu com més pistons hagi a la bomba, el líquid passa a l'interior del cilindre en la seva carrera d'expansió i posteriorment és expulsant-lo en la seva carrera de compressió, produint així el cabal. L'eficiència de les bombes de pistons és, en general, més gran que qualsevol altre tipus, vencent, generalment, pressions de treball més elevades que les bombes d'engranatges o de paletes Bomba estrella L'animació mostra com opera aquest motor hidràulic. El tambor amb els vuit pistons muntats radialment, gira al voltant d'un eix estacionari que té la funció d'una vàlvula de camisa. Un pistó és empès cap a fora en el moment just i el corró unit al pistó ha de seguir la trajectòria corba i fixa de l'anell. Això resulta en una rotació del tambor, el tambor està connectat a l'eix de sortida del motor i mou la càrrega. Es pot canviar el sentit de rotació del motor canviant la direcció del subministrament d'oli a aquest
