The discharge rate of a piston type pump
Many metering pumps are piston-driven. Piston pumps are positive displacement pumps which can be designed to pump at practically constant flow rates (averaged over time) against a wide range of discharge pressure, including high discharge pressures of thousands of psi. Piston-driven metering pumps commonly work as follows: There is a piston (so… WebAn axial piston pump is shown in Fig. 2.25.The major components are the swashplate, the axial pistons with shoes, the cylinder barrel, the shoeplate, the shoeplate bias spring, and the port plate.The shoeplate and the shoeplate bias spring hold the pistons against the swashplate, which is held stationary while the cylinder barrel is rotated by the prime mover.

WebDrum Pumps for Water and Chemicals. Push the plunger to pump water, cleaners, and chemicals. Styles A, B, and G are for thin liquids with a maximum viscosity of 700 or 750 centipoise. Styles C-F are rated for liquids up to 2, 500 centipoise. Style C are often used as hand pumps and do not come with a connector. WebDec 2, 2011 · Probably the biggest advantage to this pump type is the very high pressure capability, up to 40,000 psi. These pumps move a discrete volume of liquid on each stroke, so in order to change the flow rate the speed must be changed (see figure 4). The maximum flow/speed is limited by valve size, bearing life, inertial loads or NPSH. Flow is ...
