SELF PRIMING ![pulsation dampener](https://www.crestpumps.co.uk/hs-fs/hubfs/Website/Product%20Images/Accessories/pulsation%20dampener.jpg?width=300&name=pulsation%20dampener.jpg) IECEx Certification ATEX Zone 1 & 2 Certification Self-Regulating [Download Our Datasheet](https://www.crestpumps.co.uk/hubfs/Pulsation%20Dampeners-diaphragm-pumps.pdf) Their self regulating characteristic makes them extremely user friendly, with top notch effectiveness in protecting your pipings and machinery from water hammers generated by a diaphragm pump. The ample choice in materials for castings and diaphragms in an Equaflux dampener grants the same chemical compatibility of any accompanying pump. They have no troubles with viscosities and solids in the range of their pneumatic pumps counterparts. The Equaflux range are also availble as ATEX-certified, making them suitable for potentially explosive environments. ![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) ![Chemical-plant-refinery](https://www.crestpumps.co.uk/hs-fs/hubfs/Website/Banners/Chemical-plant-refinery.webp?width=300&name=Chemical-plant-refinery.webp) ##
