Simple design; increased wear; relatively loud, cooling system, oil separator
and sound attenuation required
Liquid ring pump
Quiet; wear resistant; sometimes requires its own processed water tank
thereby increasing the overall weight
Ejector
High power and noise; Generates overpressure and thus sludge dewatering
in suction vehicles with water reclamation technology is not possible.
