The FOODBOXER 503 food grade air operated diaphragm pump is specifically designed for use in food and hygienic applications. This AOD is manufactured with an electro polished stainless steel 316 pump body and installed with FDA approved PTFE diaphragms. Therefore, all parts that come into contact with the pumped fluid are of food grade standard. The pump connections can be supplied with different configurations including; Tri clamp, DIN or NPT.

 

This AOD has all the design benefits of a standard diaphragm pump but built with food grade materials. This FDA approved positive displacement pump can self-prime, dry run, handle fluids with viscosities up to 50000cp and has a solids passage up to 10mm; this allows it to be used for a wide range of applications within the food, beverage, cosmetics and pharmaceutical industries. The gentle pumping action also means it is excellent for handling shear sensitive fluids.

 

This diaphragm pump is Atex zone 2 as standard meaning it is suitable for operation in non-safe potentially flammable environments. As an option, this pump can come in an Atex zone 1 version if required. This AOD pump is also able to run in high humidity environments which may cause issues for other pumps fitted with electric motors.

 

The FOODBOXER 503 AOD pump can run dry for long periods and is capable of self-priming up to 5m vertically. The flow rates from this food grade diaphragm pump can be varied very easily by altering the air pressure entering the motor; this versatility allows the operator the ability to dispense very precise flow rates if required. The FOODBOXER 503 AOD pump can achieve varying flow rates up to 900L/min.

 

The patented technology in the air motor ensures that the pump will not stall if there is a significant drop in air pressure entering the motor.

FAQS

Yes, absolutely! Due to their unique design, diaphragm pumps can run dry indefinitely. As there is no mechanical seal that requires lubrication and the only pumping component is a rubber diaphragm, the pump can run without fluid for long periods without risk of damage to the internal components or motor.
This means the pump does not need lubricated air to work. Lubricated air is more expensive, oil levels must be frequently checked and the use of oil in air leads to particle emission through the pumps exhaust potentially leading to contaminated product and atmosphere.
A pump must be primed in order to operate correctly, this means that the pump casing and inlet pipe must be filled with fluid and the air removed before operation. This needs to be done manually by the pump operator for a non-self-priming pump each time the pump is used to avoid damage from dry running. A self-priming pump removes these issues by completing the priming process automatically. The air is removed from the inlet pipework and pump casing when the pump is activated. Self-priming pumps are particularly useful for installations with a suction lift on the inlet side of the pump, the pump will draw the fluid up the pipework by creating a vacuum and removing any air that is present. In ideal conditions, a self-priming pump can lift fluids up to around 6m on the inlet side, however this figure is affected by fluid viscosity, model, pipework bore and other installation conditions, therefore this figure can be much lower from case to case. Allowances must also be made for wear and tear; suction lift capabilities will be much lower for older and worn pumps.
Our food grade diaphragm pumps are available with various connections, including; DIN, Tri-Clamp and NPT. Please contact a member of our sales team for other connection types.
Please note that the standards vary by model. Our diaphragm food grade pumps comply with standards FDA and 3A for use in the food, beverage, chemical, cosmetic and pharmaceutical industries. These series are designed for maximum sterilisation when performing cleaning processes.

A clear picture of the pump system is required to make an accurate selection. The main pieces of information required include; a description of the application, bore of pipework, the fluid, viscosity, size and type of solids, flow rate and pressure/head. With these pieces of information, a pump can be sized correctly to ensure it delivers the required flow rate and pressure and that is also operates at its best efficiency point to lower lifetime costs. Viscosity is a major factor when selecting the correct size pump. A full speed pump will not transfer high viscosity fluid correctly, whereas a slower speed pump will have a much gentler pumping action. Therefore, oversizing the pump and running it slower will provide much better results. Knowing if the pump is running intermittently or continuously also allows the correct pump to be selected. For instance, a pump running continuously 24/7 will require a larger pump ran slower rather than a smaller pump at full speed. Running the motor slower and oversizing the pump will reduce wear of the pump components, therefore lowering maintenance costs during its lifetime.
ATEX is an abbreviation of “Atmospheres Explosibles”. It is a regulation set out by the European Union to ensure the safety of products that are used to handle flammable products or are installed in environments containing flammable gases, vapours, mists or combustible dusts. For instance, if the pump is being installed in an explosive environment, then only the motor needs to meet the Atex standard stopping it from causing a spark during operation and igniting the atmosphere. However, if the fluid being pumped is flammable, then the pump will also need to meet Atex standards to ensure that no sparks are caused inside the pump itself when the fluid goes through it. It is crucial that an Atex rated pump or motor are used for applications involving explosive environments or flammable fluids, using a non-Atex pump or motor in these situations is extremely dangerous and contravenes health and safety standards.
