They are built in mechanically polished AISI 316 L with a surface finish of <0.8 μm. Suitable for High Viscosity Liquids ![AISIBOXER-01 resized](https://www.crestpumps.co.uk/hs-fs/hubfs/Website/Product%20Images/Diaphragm%20Pumps/AISIBOXER-01%20resized.jpg?width=300&name=AISIBOXER-01%20resized.jpg) ATEX Zone 1 & 2 Certification FDA Compliant Rapid Emptying System [Download Our Datasheet](https://www.crestpumps.co.uk/hubfs/Product%20Downloads/AISIBoxer-diaphragm-pumps.pdf) The AISI Boxer range are ideal for moving fluids in sectors such as the food and beverage and cosmetic industries. They constitute an optimal solution for the transport of liquids and fluids with high apparent viscosity, even in the presence of suspended solid parts.   The Rapid Emptying System of the AISIBOXER pumps allows the complete emptying of the pump from the fluid present inside the product chambers. The operation can be carried out comfortably by hand without the use of tools or particular equipment. The pump will thus be free of internal impurities and ready to be washed and sanitized.   AISIBOXER pumps can be equipped with fluid ball valves with an eccentric design. Their construction form is unique in its kind and differs from normal ball valves as it allows the conveyance of fluids with large suspended solids. The eccentricity of the valve body prevents the ball from blocking during pumping operations. The balls are available in both AISI 316 and PTFE. ![chemical_plant_tint_optimized_950](https://www.crestpumps.co.uk/hs-fs/hubfs/chemical_plant_tint_optimized_950.jpg?width=300&name=chemical_plant_tint_optimized_950.jpg) ## THE CREST PUMPS LIFETIME GUARANTEE **No matter how old your pump becomes, in the unlikely scenario that you have a problem, our engineers will be on hand to diagnose the issue and help you get up and running again.

It is typically used in applications where a low flow rate, high pressure, or a pulsating flow is required.  A centrifugal pump is a type of rotodynamic pump that uses a rotating impeller to create pressure and move fluid. It is typically used in applications where a high flow rate ir required.  How does an AODD pump work?** An air operated double diaphragm pump also known as an AODD pump is a type of positive displacement pump which operates using compressed air instead of an electric motor. It consists of two flexible diaphragms connected by a shaft, which move back and forth to create suction and discharge cycles. As compressed air enters one chamber, it pushes the diaphragm outward, forcing fluid out of that side whilst simultaneously drawing fluid into the opposite chamber. A set of check valves ensures that liquid flows in only one direction. The air supply then shifts to the other chamber, repeating the cycle and maintaining a steady flow.   What are the advantages of using an AODD pump?** AODD pumps offer versatility, as they can handle a wide range of fluids, including abrasive, viscous and corrosive liquids. They are self-priming and can run dry without damage, making them ideal for unpredictable flow conditions. Additionally, they feature a simple design with minimal moving parts, leading to low maintenance and easy repair. Can AODD pumps run dry without damage?** Yes, they can run dry without damage, making them ideal for applications with variable flow or intermittent fluid supply. Unlike centrifugal pumps, which can overheat and fail without liquid, AODD pumps use air pressure to move diaphragms, allowing them to operate safely even when dry. However, while they won’t suffer immediate damage, prolonged dry running can increase diaphragm wear, so regular maintenance checks are recommended. ## Trusted By The Best ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Akzonobel2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Akzonobel2.jpg?width=142&name=Akzonobel2.jpg) ![Ballard1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Ballard1.jpg?width=142&name=Ballard1.jpg) ![biffa2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/biffa2.jpg?width=142&name=biffa2.jpg) ![Champion X1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Champion%20X1.jpg?width=142&name=Champion%20X1.jpg) ![kemira2](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/kemira2.jpg?width=142&name=kemira2.jpg) ![Vynova1](https://144022160.fs1.hubspotusercontent-eu1.net/hub/144022160/hubfs/Logos/Vynova1.jpg?width=142&name=Vynova1.jpg) ![Brewery 2](https://www.crestpumps.co.uk/hs-fs/hubfs/Brewery%202.jpg?width=300&name=Brewery%202.jpg) ## DON’T JUST TAKE OUR WORD FOR IT *Very good company with a wealth of expertise..* RAY PAGEBowman Ales Limited ## Talk to us Contact us today for your chemical pump solutions that will minimise downtime and maximise energy efficiency. ```json { "@context" : "https://schema.org", "@type" : "Organization", "address" : { "@type" : "PostalAddress", "addressCountry" : "United Kingdom", "addressLocality" : "New Milton", "addressRegion" : "Hampshire", "postalCode" : "BH25 5NN", "streetAddress" : "7 Queensway" }, "knowsLanguage" : "en_GB", "logo" : { "@type" : "ImageObject", "url" : "https://144022160.fs1.hubspotusercontent-eu1.net/hubfs/144022160/Branding/Crest-Pumps-Logo-Small-2025.png" }, "name" : "Crest Pumps Ltd", "url" : "https://www.crestpumps.co.uk/pumps/diaphragm-pumps/aisiboxer" } ```
