HC-PURE hygienic double diaphragm pump

Need a versatile hygienic pump for your food, beverage, or pharmaceutical production process? Look no further than the Verderair HC-PURE double diaphragm pump.

Engineered for superior hygiene, the HC-PURE pump boasts features that minimise contamination risks:

  • FD & SB Series: Choose between the FD series for beginning-of-process hygiene or the SB series for final-stage product protection.

  • Hygienic Materials: Constructed from electropolished SS 316L stainless steel, the HC-PURE meets the strictest hygienic design standards.

  • Easy Maintenance: Designed for fast and thorough cleaning, minimising downtime.


Verderair PURE hygienic double diaphragm pumps function similarly to standard diaphragm pumps but prioritise cleanability.

  • Compressed Air Chambers: These pumps utilise compressed air to move two flexible diaphragms within the housing, creating separate chambers.
  • Diaphragm Movement: An air valve system controls the pressurisation of the air chambers behind each diaphragm, causing them to move back and forth.
  • Fluid Movement: One diaphragm expanding creates a low-pressure zone, drawing fluid into the pump. The other diaphragm contracting creates high pressure, pushing fluid out.

Focus on Hygiene:

  • The key difference in HC-PURE pumps lies in their design and materials. They are meticulously crafted with a focus on hygiene, adhering to EC 1935/2004 and FDA regulations.
  • Features like the single-piece manifold with smooth corners and electropolished surfaces minimise crevices where bacteria can harbour, promoting a cleaner operation.

How does an AAOD Pump work and what is it used for?

We have created detailed articles explaining what a diaphragm pump is used for and how a diaphragm pump works.

How do I read an Air Operated Diaphragm Pump curve?

Global Pumps created a video explaining how to read an determine the values outlined on an AOD pump curve. Watch it here.

We also have a blog article on how to read an air operated diaphragm pump performance curve.

Where can these hygienic diaphragm pumps be used?

The Verderair PURE hygienic double diaphragm pump is available in two designs: the FD series for hygienic applications at the beginning of the production process and the SB series for hygienic applications in the final stage of the production process.

Industries involved: Food and Beverage, Pharmaceutical, Cosmetic, Dairy industry, Brewery, Winery.

What are the main features of an AOD pump?

  • They are self-priming
  • They can run dry without damage
  • They are available in different materials for pumping a range of liquids and dangerous chemicals
  • Leak free

How many sizes and materials are available?

There are four sizes available for the FD series and one size available for the SB series.

How do I know what type of HC-Pure Hygienic AOD pump to buy?

It is important that you match your requirements to the pump’s characteristics and abilities. Here are five important considerations for choosing a HC Pure hygienic diaphragm pump:

  1. Fluid: the make-up of your process fluid is crucial to the choice of pump. Does it have special or corrosive requirements? Is it clean or does it contain particles (slurry)?
  2. Viscosity: the viscosity of your process fluid is also important. More viscous fluids require more robust pumps to move them.
  3. Flow rate: you need to know how much liquid you need to move per unit time in order to choose both the correct size pump and the correct size of piping
  4. Pressure: the pressure will also be a major factor, one that intertwined with the flow rate, in choosing an appropriate pump. Refer to your pump’s “pump curve” graph to help determine the relationship between flow and pressure.
  5. Temperature: your choice of pump will need to handle the temperature of the liquid being pumped

For more information on the different types of pumps or diaphragm pump flow rate calculations read our informative blog articles.

What kind of fluid does a diaphragm pump transfer?

Fruit juices, flavours, colouring, ingredients, alcohol, chemicals, shampoo, cremes, lotions, soap, toothpaste, perfume, soup, starches, sauces, pastes, jams, dough, oil, bakery ingredients, yoghurt, cheese, milk, butter, ice cream, beer, wine, wort, yeast, flavouring.

Why do air operated diaphragm pumps freeze?

Although Verderair pumps are anti-freeze, we have created an article explaining whair operated diaphragm pumps freeze.

What are the key factors for diaphragm pump maintenance?

The good news is that AOD pumps are comparatively easy to maintain. Importantly, and like every other pump,  regularly scheduled maintenance is crucial. You want to monitor things over time, to prevent mishaps before they happen. There are essentially 4 main things to keep an eye on during the life of the pump, these include:

  1. Quality of the air used to operate the pump. Air can come in many different qualities, with various amounts of water. Impurities are removed by an in-line air-filter. Making sure that this is operated and doesn’t become clogged with debris from poor quality air is important to prevent these particles from reaching the pump and causing premature wear on the pump diaphragms.
  2. Examine the pump’s elastomers (diaphragms) routinely for signs of wear - replace these if necessary.
  3. Make sure you frequently check the fluid inlet and outlet of your pump. If either of these become clogged, it can lead to premature failure of the pump.
  4. If the pump is constructed of plastic, which can change shape over time, becoming compressed, make sure that you check the torque settings of the pump’s bolts.

What is the purchase process? How do I find out pricing for an air operated diaphragm pump?

Our Global Pumps team will discuss the application at hand, fluid being pumped and the environment the pump is entering. This will provide them with the information they require to offer a quote and outline pricing and other considerations that should be made.

The Verderair HC-PURE series of hygienic double diaphragm pumps is designed for various hygienic applications. Designed to the highest standards, these pumps offer enhanced cleanability minimising the risk of bacteria contamination and traps. They are easy maintain and bost a long lifespan, resulting in less downtime and enhancing the efficiency of your production process. 

Best cleanability

Verderair HC-PURE pumps undergo an electro-polishing process. This creates a smoother surface, making it harder for products to stick and reducing bacteria build-up. The smoother surface also resists corrosion better.

These pumps can be cleaned with traditional strip cleaning methods or with CIP/SIP systems. Additionally, the rotatable stand allows for effortless draining, preventing trapped liquids and promoting thorough cleaning.

Easy to maintain

Verderair HC-PURE hygienic diaphragm pumps are designed for easy maintenance. Housing screws and manifold clamps are easily removed for complete disassembly and cleaning. Additionally, the pumps feature long-life PTFE/EPD overmolded diaphragms and a 100% self-lubricated, maintenance-free air valve. This reduces maintenance time and keeps your production running smoothly.

Highest hygienic design principles

Verderair HC-PURE pumps are meticulously crafted with superior hygiene in mind. Their design and production adhere to the strictest hygienic principles, ensuring compliance with EC 1935/2004 and FDA regulations. This commitment to hygiene is evident in the single-piece manifold, featuring smooth corners and bends. This eliminates crevices where bacteria can harbor, promoting a cleaner and safer production environment. For further enhanced cleanability, the pumps can be equipped with your choice of hygienic DIN 11851 or Tri-clamp connections.

Two designs:

The Verderair HC-PURE hygienic double diaphragm pump is available in two designs: the FD series for hygienic applications at the beginning of the production process and the SB series for hygienic applications in the final stage of the production process.
