Advantages of Positive Displacement Vacuum Pump
Precise flow regulation
Pd pumps deliver a fixed volume of fluid per revolution, enabling unparalleled precision in flow control. This characteristic makes them indispensable for processes requiring exact fluid dosing, such as chemical injection.
Handling highly viscous fluids
Where centrifugal pumps often struggle, pd pumps excel. Their design allows the consistent movement of thick, viscous fluids like oils, syrups, or sludges without performance degradation.
Self-priming capabilities
Many pd pump types are inherently self-priming, meaning they can draw fluid into the pump from a source below its suction line. This eliminates the need for external priming mechanisms, saving time and operational complexity.
High-pressure applications
Pd pumps maintain constant flow rates even under significant system resistance, making them ideal for high-pressure applications such as equipment cleaning or fluid injection in oil fields. These advantages highlight why pd pumps are often the go-to choice for challenging operational conditions where precision and reliability are paramount.
Tanker unloading and loadingfuel transfer loading
Usually fuels, but also chemicals, food ingredients and oils, to other fluids ranging in viscosity from those thicker than water to sludges.
Using positive displacement pumps ensures tankers can be stripped (completely emptied), with dry run designs ensuring pump damage does not occur. They are very effective at priming and ensure siphoning doesn’t occur where once the pump is stopped as in centrifugal designs.
Metering, dosing and sampling
Precise repeated delivery of fluids into a process means any pump selected must provide a set volume per revolution. This rules out centrifugal designs where it is possible for fluid to vary in flow or recirculate within a pump head.
Fluids used in these processes can vary by application but can include chemicals such as flocculants, coagulants in wastewater treatment, chemicals, flavourings, fuel, dyes, or paint. Pd pumps are known for their accuracy enabling dosing accuracies > 99% to be achieved.
