Positive Displacement Pump – Efficient Solution for Challenging Conveying Tasks
Highly efficient pump solutions for demanding applications: Positive displacement pumps are the first choice for the precise and continuous pumping of viscous, abrasive, or sensitive media.
From the chemical and food industry to the environment and energy, oil and gas, and mining, positive displacement pumps offer the possibility of precise, reliable, and efficient pumping of a wide variety of media. Discover why a positive displacement pump is the optimal solution for your application.
What is a positive displacement pump?
Customised Consulting
A positive displacement pump conveys liquids by displacing the medium in a closed space. Compared to centrifugal pumps, positive displacement pumps work with a constant displacement volume and enable even, low-pulsation conveyance – independently of pressure fluctuations. A positive displacement pump offers numerous advantages, especially for highly viscous, shear-sensitive or solids-laden media.
Functionality and advantages
A positive displacement pump works based on the principle of volume displacement. The pumped medium is transported using rotating or oscillating movements. This offers numerous advantages:
- High efficiency: Constant flow rate independent of back pressure
- Gentle pumping: Ideal for fragile or shear-sensitive media
- Self-priming and dry-running: For maximum operational flexibility
- High-pressure capability: Ideal for demanding applications with variable operating conditions
The solution for your requirements
There are numerous different types of positive displacement pumps. NETZSCH Pumps & Systems, the global specialist in handling complex media, offers a broad portfolio. Each pump is precisely tailored to your requirements, enabling you to achieve reliable and efficient pumping.
Progressing cavity pumps
NEMO®progressing cavity pumps are ideal for precise and continuous conveyance of high-viscosity, shear-sensitive or solids-laden media. They ensure low-pulsation conveyance at a constant volume flow – even under fluctuating operating conditions.
Rotary lobe pumps
For abrasive and solids-laden media, TORNADO® rotary lobe pumps offer a compact and powerful solution. Their innovative design makes them highly robust and allows them to be flexibly integrated into various processes, even where space is limited.
Multi screw pumps
When it comes to pumping low-viscosity liquids such as lubricant oils, fuels or other free-flowing substances, NOTOS®multi screw pumps are the ideal choice. They are particularly energy-efficient and characterised by high pumping capacity and minimal pulsation.
NETZSCH offers an extremely resistant solution for highly aggressive chemicals and strongly abrasive media with its PERIPRO®peristaltic pumps. These pumps can run dry, are self-priming, and do not require valves or seals, which makes them particularly low-maintenance and durable.
Thanks to decades of experience and continuous innovation, NETZSCH ensures each pump is precisely tailored to the individual requirements of the respective application. You will benefit from maximum efficiency, reliability, and optimal process safety.
Applications of positive displacement pumps
Positive displacement pumps are indispensable in numerous industries, as they enable precise, reliable and efficient pumping of a wide range of media. In the chemical and pharmaceutical industries, they are used for exact dosing of sensitive substances and chemicals. The food and beverage industry benefits from their hygienic design, which ensures the gentle pumping of highly viscous products such as honey or yoghurt. In the oil and gas industry, they enable you to safely and efficiently convey crude oil, bitumen or drilling muds – even under extreme conditions. They are also indispensable in mining and environmental technology for conveying abrasive media such as slurries or wastewater. Thanks to customised solutions, NETZSCH ensures your processes run optimally – reliably, economically and efficiently.
