PRODUCT INFORMATION

Hygienic centrifugal pumps are designed to provide reliable fluid transfer while meeting the cleanliness requirements of sanitary processing environments. Smooth wetted surfaces and crevice-free designs help minimise product build-up, while materials such as 316L stainless steel support effective cleaning and corrosion resistance.

The range covers conventional centrifugal pumps for clean, low-viscosity liquids through to specialised and hybrid designs for fluids containing solids, fibres or higher viscosities. Options are also available to support CIP (Clean-In-Place) and SIP (Sterilise-In-Place) processes.

Why use stainless steel centrifugal pumps for hygienic processing?

Stainless steel centrifugal pumps are widely used in hygienic processing due to their durability, corrosion resistance and ability to withstand frequent cleaning. The range includes pumps with 316L stainless steel wetted components, providing a smooth, non-porous surface suited to food, beverage, dairy and other sanitary applications.

However, selecting a food-grade centrifugal pump involves more than the stainless steel grade alone. Surface finish, pump geometry, seals and compatibility with the product and cleaning chemicals should also be considered.

Global Pumps can assess these requirements to help select the most suitable hygienic centrifugal pump for the application.

Packo ZS Hygienic Twin Screw Pumps

For hygienic applications involving products across a wide range of viscosities, the Packo ZS series provides a versatile solution for both product transfer and CIP processes.

These hybrid pumps combine characteristics of centrifugal and positive displacement pump technologies. Their broad speed range allows them to transfer products from light liquids to thick pastes, while also handling lower-viscosity cleaning fluids at higher speeds during CIP. Gentle, pulsation-free operation helps maintain the texture and consistency of sensitive products.

The ZS series is particularly suited to dairy, beverage, food processing, pharmaceutical and cosmetic applications, including milk, yoghurt, cream, syrups, pastes, fillings and other viscous products.

Key benefits include:

  • gentle, low-shear and pulsation-free operation
  • bi-directional pumping capability
  • hygienic stainless steel construction
  • 3-A and EC 1935/2004 certified
  • suitable for sensitive and viscous products

WORKING PRINCIPLE

A hygienic centrifugal pump works by using a rotating impeller to transfer energy from the pump motor to the liquid.

Product enters the pump through the suction inlet and reaches the centre of the impeller. As the impeller rotates, the liquid is accelerated outwards towards the pump casing. This velocity is converted into pressure, allowing the liquid to flow through the discharge and into the process system.

Because centrifugal pumps provide smooth, continuous flow, they are particularly well suited to moving relatively low-viscosity liquids at higher flow rates.

In hygienic applications, the same centrifugal pumping principle is combined with sanitary construction. Stainless steel wetted components, smooth surfaces and designs that minimise crevices help make the pump easier to clean and suitable for sensitive food and beverage processes.

Specialist pumps within the range operate differently. Hybrid technologies, including hygienic twin screw and screw centrifugal pumps, combine characteristics of centrifugal and positive displacement pumping to accommodate applications involving higher viscosities, solids or different process requirements.

APPLICATIONS

Sanitary centrifugal pumps are widely used where liquids need to be transferred efficiently while maintaining high standards of cleanliness. Flow rate, pressure, viscosity, solids content, temperature, suction conditions and cleaning requirements should all be considered when selecting the most appropriate pump for an application.

Common industries and applications include:

  • Dairy processing: milk, whey, curd and other dairy products
  • Breweries: beer, wort, yeast and process water
  • Wine and beverage production: wine, fruit juices, soft drinks and other beverages
  • Food processing: liquid food products, ingredients and process fluids
  • Vegetable processing: washing and blanching water and liquids containing vegetable matter
  • Filtration: circulation and transfer through beverage and process filtration systems
  • Pasteurisation: transferring products through heating and cooling processes
  • Evaporation systems: product circulation during concentration processes
  • CIP systems: circulation of cleaning fluids through hygienic processing equipment
  • Pharmaceutical and cosmetics: suitable sanitary liquid-transfer and processing applications
  • Water treatment: clean and process water transfer
  • Biogas, biodiesel and bioethanol: suitable liquid transfer and circulation processes

FAQs

What is a hygienic centrifugal pump?

A hygienic or sanitary centrifugal pump is a centrifugal pump specifically designed for processes where cleanliness and contamination control are important. These pumps typically feature stainless steel wetted components, smooth internal surfaces and designs that facilitate effective cleaning. They are widely used throughout food, beverage and dairy processing.

What liquids can a hygienic centrifugal pump handle?

Hygienic centrifugal pumps are particularly effective for relatively low-viscosity liquids such as milk, whey, beer, wine, fruit juice, water and other free-flowing process fluids.

Specialised centrifugal designs can also handle liquids containing solids and fibres. For example, the Packo IFF range provides increased clearance between the impeller and casing to allow certain solids and fibrous material to pass through without clogging.

When should I choose a centrifugal pump for a hygienic application?

A centrifugal pump is generally a good choice when you need to transfer relatively large volumes of low-viscosity liquid efficiently and continuously.

For thicker, highly viscous or particularly shear-sensitive products, a positive displacement pump may be more appropriate. Product characteristics, flow requirements, system pressure and cleaning requirements should therefore be considered before selecting the pump technology.

Are sanitary centrifugal pumps suitable for CIP?

Many sanitary centrifugal pumps are designed for Clean-In-Place processes. Depending on the pump and system design, they can be used to circulate cleaning solutions through processing equipment without dismantling the system.

Global Pumps can help determine the appropriate pump based on the required CIP flow, pressure, temperature and cleaning chemicals.

Are hygienic centrifugal pumps made from SS 316 stainless steel?

The hygienic centrifugal pump range includes models manufactured from 316L stainless steel pump casings, providing smooth, corrosion-resistant surfaces suited to hygienic processing.

When specifying SS 316 centrifugal pumps for a sanitary application, the complete construction should be considered rather than the stainless steel grade alone. Surface finish, seals, internal geometry and cleaning requirements can all affect whether a pump is suitable for the intended process.

What makes a centrifugal pump suitable for food-grade applications?

A centrifugal pump for food-grade processing should be constructed from materials compatible with the product and designed to allow effective cleaning. Depending on the application, considerations can include stainless steel wetted parts, smooth surface finishes, minimal crevices, suitable seals and compatibility with CIP or SIP procedures.

The specific hygiene standards or certifications required will depend on the product, process and regulatory requirements.

Can a sanitary centrifugal pump handle solids?

It depends on the pump design. Standard hygienic centrifugal pumps are primarily intended for liquids, although some can handle limited soft solids.

Where the liquid contains larger solids, fibres or vegetable matter, a pump specifically designed for this duty should be selected. The IFF pump has increased clearance between the impeller and casing to allow solids and fibrous material to pass through with a reduced risk of clogging.

Can hygienic centrifugal pumps handle high-viscosity products?

Centrifugal pumps generally perform best with low- to moderate-viscosity liquids. As viscosity increases, centrifugal pump performance and efficiency can decrease.

For highly viscous products such as pastes, creams, thick syrups or doughs, a positive displacement or hybrid pump technology may be more suitable. For example, hygienic twin screw pumps can handle a much wider viscosity range while providing gentle product transfer and supporting CIP processes.

Global Pumps can assess viscosity, required flow, pressure and product characteristics to recommend the appropriate hygienic pump technology.
