Rotary and Reciprocating Volumetric Pumps – Definition and Operating Principle
In volumetric pumps, fluid transfer occurs by moving a fixed volume, driven by the rotations of a rotor element. The flow rate is the result of the continuous process of movements that drive the fluid, so the revolutions of the drive and the volume of the chamber largely determine the total flow rate. Due to their general operation, they are classified as positive displacement pumps.
During operation, the fluid enters due to the vacuum created in the suction line, as a result of the movement of various mechanisms such as pistons or gears, which determine whether the volumetric pump is rotary or reciprocating.
This type of pump is ideal for applications requiring low flow rates and high fluid pressures. They can operate efficiently at low speeds and are unaffected by the viscosity of the product. In these pumps, the discharged flow rate is independent of pressure, making them suitable for various industrial applications, such as product dosing.
Types of Volumetric Pumps
Depending on the type of drive, volumetric pumps can be:
Rotary Volumetric Pumps: In these pumps, the fluid is confined in one or more compartments that move from the intake area (low pressure) to the discharge area (high pressure), driven by a rotary mechanism. This category includes vane pumps, gear pumps, lobe pumps, screw pumps, and peristaltic pumps.
Reciprocating Volumetric Pumps: These consist of one or more pistons in alternating motion and various valves responsible for fluid suction and discharge. They can be piston or diaphragm pumps. The latter has the advantage of being suitable for abrasive, corrosive, or hazardous fluids, as they report zero leakage.
In our online catalog, you’ll find both rotary and reciprocating volumetric pumps. All specifications for our volumetric pumps are available in a printable PDF format, accessible from our online catalog.
