Progressive cavity pumps

Key features

Progressive cavity pumps are a type of rotary volumetric pump that consist of a helical rotor, which turns inside a helical stator When the rotor turns into the stator, the honeycomb progresses spirally along the axis of the pump transferring the product from the pump suction to the pump discharge. They are pulsation-free and capable of handling higher pressure (up to 24 bars), making them ideal for jobs in the food sector that require a steady flow of liquid regardless of viscosity.

Pump principle

Food sector applications

PCPs are largely used in food processing industries. Designed according to the strictest hygiene standards, these pumps are appreciated for product respect and steady flow. The PCP technology is ideal for dairy products (milk, eggs, and yogurts). These PDPs are also prevalent in the sector of fruit handling, assist in agricultural food production and are used in the cosmetic industry to produce and maintain high quality products whilst promoting the latest level of hygiene standards.

Recommended uses

Progressive cavity pumps have a reputation for their wide capabilities, and with PDP varieties available for food transfer pumps and systems there are many uses for progressive cavity pumps. Food transfer pumps are an integral aid when it comes to handling delicate ingredients and creating expensive recipes with components that can be often difficult to work with. However, when it comes to fluid processing, PCPs are capable of dispersing both fragile and thick liquids, including corrosive substances and liquids that contain solids, without damaging the product.

Advantages

  • Easy to maintain
  • Cleanable in place (CIP)
  • Low shear pump
  • Flow rate is proportional to running speed
  • PCPs are reversible to suit your requirements

Performances

  • Pressure: up to 24 bars (standard pump)
  • Flowrate: from 3l/h to 180 m3/h
  • Particle sizes: up to 32 mm

Dosing pumps

Key features

Dosing pumps are small positive displacement pumps, designed to offer a precise flow rate by drawing a specific amount of liquid into a chamber to be injected into another container or substance. They are usually powered by an electric motor or air actuator, and controlled by an external control system or an internal pump controller, which allows for minimal loss.

Pump principle

Food sector applications

Dosing pumps are prevalent across the food sector. These pumps are highly appreciated by convenience food and bakery manufacturing plants for their capacity to dose fluids with particles with a high level of accuracy at high flow rates. They can also be employed in the handling of dairy products, sugar and starches as well as meat, fish and animal food.

Recommended uses

For food applications, dosing pumps are integrated into dosing or filling systems. These are designed to reduce waste, making use of their highly efficient inline injection. Dosing pumps can handle a range of fragile fluids with solids (up to 48 mm) which makes them suitable for use over a number of industries.

Advantages

  • Capable of dosing precise amounts and minimising waste
  • Cleanable in place (CIP)
  • Dosing pumps are extremely adaptable to your existing industry’s facilities
  • No emulsion, no aeration, no shearing: respect of the pumped product

Performances

  • Pressure: up to 20 bars
  • Speed: up to 60 strokes /min
  • Accuracy: +/- 0.5 %
  • Particle sizes: up to 48 mm

Peristaltic pumps

Key features

Peristaltic pumps, also known as hose pumps, are positive displacement pumps, a type of rotary pump which contain a number of rollers that squeeze a hose as it rotates. They are named so because they use the peristaltic principle, whereby the twisting and compression of a soft elastomer hose allows fluids to be transferred through the system. Peristaltic pumps are available in both high and low pressure options, with the option to choose between different flow rates, as well as whether to run continually or disperse smaller amounts.

Pump principle

Food sector applications

Praised for their gentle handling of sensitive substances, peristaltic pumps are used in the culinary industry in the creation of crushed vegetables, fruit puree, ferments and more everyday food sector applications. This wide PDP usage ranges across the food sector from fruit & vegetable processing plants to the slaughterhouse, making peristaltic pumps a prevalent choice across the food sector at all stages of processing.

Recommended uses

Peristaltic pumps can cover a variety of applications, as they are suitable for abrasive, corrosive and fragile liquids. With no shearing and no internal slip, these pumps are ideal to handle fragile products. Peristaltic pumps can be used for any kind of liquid (corrosive, abrasive, fragile, with solids), making them ideal to use for food applications, as they can be adapted to suit your company’s needs. Treat soya oil, ferments, tomato puree and more with this versatile pump.

Advantages

  • They require no seal to keep the liquid inside the tube, so there is no leakage
  • Peristaltic pumps only have one wearing part, as it is only the hose that will come into contact with the product
  • The pump will automatically start self-priming without the need for additional equipment
  • Capable of running at different speeds, as well as dry running without the risk of any damage
  • Peristaltic pumps offer low life cycle costs (LCC) and easy maintenance

Performances

  • Pressure: up to15 bars
  • Flowrate: from 30 l/h to 65 m3/h
  • Viscosity: 40 000 cPo
