Disadvantages Requires timing gears Requires two seals Reduced lift with thin liquids Plungerpump Pistonpump Advantages Disadvantages Wide pressure range - can achieve very High operating and maintenance costs. high pressures Pressure can be controlled without Typically heavy and bulky affecting flow rate. Pressure and flow rate changes have little Typically only handles lower flow rates effect on performance. Capable of moving viscous fluids, slurries, Pulsating flow and abrasives with proper valve design. Gear pump Advantages High speed High pressure No overhung bearing loads Relatively quiet operation Design accommodates wide variety of materials Disadvantages
