Power Energy Gulf supplies hygienic pumps for food, dairy, beverage, pharmaceutical and cosmetic plants in Saudi Arabia and the GCC, including the hygienic and food-grade progressive cavity pumps from Nova Rotors. A hygienic pump is built so that product can not lodge inside it and it can be cleaned properly, which protects product quality and food safety.
Hygienic Progressive Cavity Pumps from Nova Rotors
Nova Rotors makes a range of hygienic progressive cavity pumps for food and beverage duties, including the DX, JX, DXO and DXC series, the D Diamond series and versions with hoppers for thick products. They share the features hygienic users look for:
- Hygienic design with smooth stainless steel product-contact surfaces
- Designed to drain and to avoid dead zones where product can stagnate
- Gentle, low-shear pumping that protects delicate products
- Handles viscous products and solids, with hopper versions for very thick products
- Self-priming with steady, low-pulsation flow
- Sealing options from single mechanical seals to double mechanical seals and quench arrangements
Certificates and ratings vary by model and option. Tell us your product and standards, and we will confirm what the exact pump holds.
Where Hygienic Pumps Are Used
- Dairy: milk products, yoghurt, cheese and butter
- Beverages: juices, wine, brewery and distillery products
- Food: sauces, chocolate, tomato products, fruit and vegetable pulps, sugar products
- Pharmaceutical and cosmetic: creams, emulsions, oils and liquid soaps
- Chemical: viscous or shear-sensitive products needing a clean pump
What Makes a Pump Hygienic
- Smooth, polished surfaces in contact with the product
- No crevices, dead zones or trapped pockets
- Drainable casings, so cleaning liquid and product run out
- Materials safe for food contact
- Seals and joints designed to be cleaned, with cleaning connections where needed

Sanitary Lobe, Centrifugal and Progressive Cavity Pumps
Three pump types dominate hygienic duty. A sanitary lobe pump moves product with two rotating lobes and suits thick, delicate products at moderate pressure. A hygienic centrifugal pump (also called a sanitary centrifugal pump) suits thin, clean liquids such as water, milk, juice and beverages at high flow. A hygienic progressive cavity pump handles the thickest, most shear-sensitive and particle-laden products, with steady low-pulsation flow. Power Energy’s hygienic range is built around progressive cavity pumps from Nova Rotors. If your product is better served by a lobe or centrifugal design, we will tell you honestly, and share what we can supply. Read our comparison: how to choose a hygienic pump.
How to Choose a Hygienic Pump
Start with the product: its viscosity, temperature, solids and sensitivity to shear. Then define flow, pressure, the cleaning method and the standards your plant needs. See how to choose a hygienic pump.

Frequently Asked Questions
What is a hygienic pump?
A hygienic pump is designed so that no product can lodge in it and it can be cleaned thoroughly. It has smooth, polished product-contact surfaces, no dead zones or crevices, drainable casings and materials suitable for food contact. Hygienic pumps are used where product purity matters, such as food, dairy, beverage, pharmaceutical and cosmetic processing.
What is a hygienic progressive cavity pump?
It is a progressive cavity pump built with hygienic design: a helical rotor turning in an elastomer stator, with smooth stainless steel surfaces, drainable construction and designs that avoid dead zones. The gentle, low-shear pumping action suits thick, delicate or particle-laden products.
Which products can a hygienic progressive cavity pump handle?
Viscous, shear-sensitive and solids-laden products such as milk products, yoghurt, cheese, butter, chocolate, sauces, fruit and vegetable pulps, tomato products, wine, beverages, brewery and distillery products, and cosmetic and pharmaceutical fluids.
Can the pump handle products with solids?
Yes. Progressive cavity pumps move solids gently, so they suit pulps, products with pieces and thick slurries. The size of solids that can pass depends on the model, so tell us the product and particle size.
Can hygienic pumps be cleaned in place?
Many hygienic designs support clean-in-place (CIP) cleaning, and some are built with drainable casings and cleaning connections. Whether a model suits your CIP regime depends on the model and options, so share your cleaning procedure with us.
Which standards and certificates apply?
Hygienic designs are commonly checked against standards such as EHEDG and 3-A. Certification varies by model, so ask us and we will confirm the certificates for the exact pump you are considering.
What do you need to recommend a pump?
Send us the product, viscosity, temperature, flow, pressure, solids content, cleaning method (CIP or SIP) and any standards you require.
What is a sanitary lobe pump?
A sanitary lobe pump is a positive displacement pump with two rotating lobes that carry product around the casing. It is gentle and easy to clean, and suits thick and delicate products at moderate pressure.
What is a hygienic centrifugal pump?
A hygienic centrifugal pump, also called a sanitary centrifugal pump, is a centrifugal pump built with polished surfaces and drainable design for food, dairy and beverage use. It suits thin, clean liquids at high flow, but not very viscous products or products with large solids.
Which is better for my product: lobe, centrifugal or progressive cavity?
Thin, clean liquids suit hygienic centrifugal pumps. Thick, delicate products suit sanitary lobe pumps. The thickest, most shear-sensitive and solids-laden products suit hygienic progressive cavity pumps. Send us your product details and we will advise.
