NETZSCH — industrial progressive cavity pumps for gentle and reliable fluid transfer
NETZSCH is a global technology specialist in industrial pumping solutions, widely recognised for its high-quality progressive cavity pumps. Within the food processing industry, these pumps are particularly valued for their ability to transfer liquids and viscous products gently, accurately and reliably.
At Barsso, we focus exclusively on NETZSCH progressive cavity pumps, which are frequently integrated into mixing installations, batching systems and product transfer processes where controlled, low-shear pumping is essential.
Who is NETZSCH?
NETZSCH is an international manufacturer with decades of experience in fluid handling technology. The company develops pumps that are designed for demanding industrial applications requiring precision, durability and process stability.
In food processing environments, NETZSCH pumps are known for their robust construction, hygienic execution options and long service life, making them a reliable choice for continuous operation.
What does NETZSCH do?
NETZSCH designs and manufactures progressive cavity pumps for applications where conventional centrifugal pumps are not suitable. These pumps are used to handle:
- shear-sensitive liquids
- high-viscosity fluids
- multiphase products containing solids
- products requiring accurate and stable flow control
Although NETZSCH offers a broad portfolio of pumping technologies, Barsso follows only the progressive cavity pump range, as it fits perfectly within food processing and mixing applications.
NETZSCH progressive cavity pumps — core technology
Progressive Cavity Pump — Operating Principle
A progressive cavity pump is a positive-displacement pump that moves product through a sequence of sealed cavities formed between a helical rotor and a flexible stator.
How it works
- the rotor turns eccentrically within the stator
- sealed cavities progress from inlet to outlet
- product is transported smoothly and continuously
- pressure builds gradually without turbulence
This principle ensures low pulsation, minimal shear and highly predictable flow, even at varying speeds.
Key advantages in food processing
NETZSCH progressive cavity pumps provide several important benefits for food processors:
- gentle product handling, preserving texture and structure
- uniform, continuous flow without pressure spikes
- excellent performance with viscous products
- ability to pump products containing particles
- accurate volumetric dosing capability
- reversible flow, if required
- hygienic design options for food-grade environments
These characteristics make them ideal for sensitive food products.
Applications in mixing and process installations
Integration with mixing systems
Progressive cavity pumps are commonly used as part of mixing installations, where they serve to:
- feed liquids into mixers or emulsifiers
- recirculate product to maintain homogeneity
- transfer finished product to downstream processes
Their stable flow ensures consistent mixing results and protects product quality.
Transfer of viscous food products
Typical food products handled by NETZSCH progressive cavity pumps include:
- sauces and dressings
- emulsions and liquid batters
- purees and pastes
- dairy and egg products
- fruit and vegetable preparations
The pump design allows these products to be conveyed without foaming or separation.
Dosing and feeding applications
Thanks to their predictable displacement, progressive cavity pumps are also well suited for:
- accurate dosing into process vessels
- feeding filling and packaging machines
- controlled batch transfer operations
What NETZSCH progressive cavity pumps are specialised in
NETZSCH progressive cavity pumps specialise in delivering:
- controlled and repeatable fluid transfer
- low-shear pumping for sensitive products
- stable performance across a wide viscosity range
- compatibility with hygienic process requirements
- reliable operation in continuous industrial environments
They are a valuable addition to mixing, batching and processing lines where process stability is essential.
