Volumetric Sanitary Pump Classification

There are lots of volumetric sanitary pump types available, but which one is right for you?

Volumetric sanitary pumps, in which its operating principle is based on hydrostatics, the increase in pressure is made by the thrust of the walls of the chambers that vary their volume. In this type of pump, in each cycle, the propeller organ positively generates a given volume or displacement. In the case of being able to vary the maximum volume of the displacement, we are talking about variable volume pumps. If that volume cannot be varied, then it is said that the pump is of fixed volume. In turn, these types of sanitary pumps can be subdivided into:

1. Alternative piston pumps, in which there are one or several fixed compartments, but of variable volume, by the action of a piston or a membrane. In these machines, the movement of the fluid is discontinuous and the processes of loading and unloading are carried out by valves that open and close alternately. Some examples of this type of pump are the reciprocating piston pump, the rotary piston pump, or the axially operated piston pump.

2. Rotary or roto-static volumetric pumps, in which a fluid mass is confined in one or several compartments that move from the entrance area (low pressure) to the exit zone (high pressure) of the machine. Examples of such machines are the vane pump, the pump lobes, the gear pump, the screw pump, or the peristaltic pump.
