Introducing - The Quantex Bag-In-Box Pump Range
The Quantex Bag-In-Box (BiB) range of pumps is one of our most popular product options, with flow rates ranging from an impressive 1.5 to 41 mL/s. It operates using a positive-displacement, rotary pump system and is a single-use pump designed to be integrated directly onto a bag-in-box pouch (or equivalent container) packaging arrangement.
By sealing the product within the pack and expelling it with the aid of a Quantex Bag-In-Box pump, the product remains contained, minimising any cross-contamination, wasted product, or mess, and reducing maintenance between pack changeovers.
The 19mm rotor most commonly carries three cavities, each with a resolution of 0.5m, and some of the Quantex Bag-In-Box range can also be configured to provide in-pump dilution. The range includes:
Key Technical Features useful for the Food and Beverage Industries
The Quantex Bag-In-Box range is ideally suited for the Food and Beverage industry, especially when it comes to needing a pump that can suck highly viscous solutions such as melted chocolate, concentrated syrups, spreads, condiments and dairy products like milk, cream and yoghurt. Below lists a variety of ways this pump is suitable:
Positive Displacement Rotary Mechanism - As the pump uses a rotary fixed-displacement principle, it can therefore move a fixed volume per rotation which can eliminate the need for additional sensors or weighing scales.
High Vacuum Capability - The self-priming Quantex Bag-In-Box pump range has been designed to achieve significant vacuum (suction) at its inlet. This strong suction permits very high evacuation of the connected product pack, meaning less residual product is left behind within the pack at the end of use.
Pumping Viscous Solutions - The pump range can easily handle thick, viscous solutions, including shampoos, conditioners, creams, melted chocolate, syrups, etc. Because the pump’s inlet can maintain suction even when solutions are viscous (i.e., have higher resistance to flow), the pump can still pull product even as resistance increases (e.g. toward the end of the bag when it is collapsed).
Pump-Range Options - There are various products within the Bag-In-Box pump range, optimised for high pressure or high speed (SD/HP/HS/DL), to cope with tougher flow resistance or faster flow requirements.
A Sealed, Hygienic System - as the pump attaches directly onto the vacuum pack filled with its solution, the product can either be dispensed straight from its outlet, or it can be connected directly to the distribution line, either way, reducing the risk of cross-contamination or degradation of the product from exposure to air. When the pack is empty or the product needs to be swapped out, the whole pump (and pack) can be effortlessly replaced as one, which reduces cleaning (from wasted product and spills) and downtime (from maintenance in between product uses).
Reverse Cycle and Bag Evacuation - An additional benefit to the Quantex Bag-In-Box pump range is that the pumps can also reverse cycle (reversing the suction from the pump momentarily). This means that at the end of the dispense, the last remnants of solution could be ‘sucked back up’ into the pump, reducing product spill or wastage, or congealing on the faucet.
Handling Thick, Viscous Solutions
The Quantex Bag-In-Box pump range is particularly recognised within the food and beverage industry for its ability to handle highly viscous solutions (including melted chocolate, condiments (i.e. ketchup and mayonnaise) and yoghurt). By utilising a vacuum pack, the food and liquid can be sealed within the pack hygienically and can be released with high vacuum suction for better bag evacuation. This then dramatically reduces the amount of product wastage. The video below shows how you can now accurately dose thick, viscous food products such as cream and butter icing directly onto cupcakes:
The Quantex Bag-in-Box pump range is a direct replacement for a gravity-fed wine tap with the benefits of precision dosing at speed. The standard bag's inlet is compatible with a Quantex Bag-in-Box (BiB) gland and is available in low-pressure, high-pressure, dilution and high-speed pump options.
In the video below, we show how the Bag-In-Box pump can be attached directly to the liquid pack and clip into a standard motor driver with a controller to effortlessly dispense thick viscous solutions, like hair shampoo and conditioner:
What makes Quantex pumps unique is their ability to handle far higher concentrations than others, due to the pump’s unique high-vacuum and high-pressure capabilities. This means many of our pumps can transfer viscosities up to 100,000cP (which is roughly the consistency of a thick hair conditioner or sour cream), so thick syrups, for example, are entirely possible, as shown in the video below:
(Please note, this is the Quantex QX25-SD pump, part of the Low Flow pump range).
In-Pump Dilution
When a product requires additional solutions during dispense, e.g concentrated juices needing water added to the mixture at dispense to dilute the solution, the Quantex Bag-In-Box pump range provides the perfect solution.
For example, the video below shows how a variety of different concentrated juices are easily dispensed at a variety of dilution levels:
As our dilution pumps can effortlessly mix water with concentrates at the point of dispense, they can make ready-to-drink beverages with no stratification and can easily dispense real fruit pieces and seeds up to 2mm in diameter with no damage.
The additional benefit to providing liquid solutions through in-pump dilution is the impact it can have on a company's carbon footprint. By providing a concentrated solution (that can then be diluted at its final location), the volume of liquid that needs to be transported can be significantly reduced, therefore reducing the size of the distribution channel, packaging and related costs.
With a Quantex pump, you can dilute in-pump with a ratio of up to 500:1, which equates to removing 80 – 99% of the water from the distribution channel, which (in some cases) is the equivalent of reducing the transportation from five vehicles to just one, creating a massive reduction in shipping costs and transportation emissions.
Reducing Costs
Due to its design and our manufacturing facilities, the Quantex Bag-In-Box pump range is very reasonably priced, especially because it can be attached directly to the solution pack to comprise a part of the product packaging instead of being a fixed component in the machine.
This means that when the pack is emptied or requires a product changeover, the whole unit can be simply swapped out and recycled/ replaced. This means there’s no fluid travelling through the fixed parts of the machine; therefore, products can be swapped in and out of the same channels in seconds, without cross-contamination, providing valuable uptime for manufacturing lines as well as a reduction in maintenance and management costs, as you don’t need highly skilled and expensive labour to do so.
It also reduces the costs associated with product wastage (as the pump can reverse cycle, pulling back in those last few drops). Additionally, the added health and safety benefit from containing the product is high (as there’s minimal risk of slips and falls from any product between pack-changeovers).
Quantex pumps use a positive displacement rotary action, and all that is required to drive the pumps is a simple motor drive with low power consumption, meaning expensive, power-hungry machinery isn’t required.
Suitable for Other Markets
But it’s not just the Food and Beverage industry that benefits from using the Quantex Bag-In-Box range of pumps. There are other markets and use cases where our range of pumps are especially advantageous:
| Market / Application | Why the Quantex Bag-In-Box Pump is Well-Suited |
| Food and Beverage | Dispensing syrups, chocolate, sauces, condiments, yoghurt, dairy and creams. For example, spreads or fruit concentrates where solid particles are present, high viscosity chocolates, and low temperature viscous items or products that need hygienic containment. |
| Personal Care / Cosmetics | Shampoos, body creams, conditioners, and lotions that are thick, often shear sensitive, and require cleanliness. The Bag-In-Box pumps allow filling and dispensing without contamination and with better dose control. |
| Bulk Dispense / Refill Retail | Where consumers or businesses dispense from bulk containers or self-serve environments, having a system that can evacuate the container fully, prevent drips, and provide quick changeover between products is greatly appreciated. |
| Industrial / Chemical | Viscous chemicals/detergent concentrates/solutions that need to be kept in separate storage packs until dispensed, or where residual waste or handling issues are costly and safe and clean transfer is necessary. |
| Chocolate and Confectionery | As chocolate’s viscosity can vary greatly, being able to handle a range of thick viscosities with no damage to the solution (like overheating or shear damage) is beneficial. |
| Food Service / Retail Dispensing | E.g. soft-serves, dessert creams, condiments in restaurants or self-service locations such as food courts or fast food chains. Minimal maintenance, combined with hygienic dispensing are substantial advantages. |
Conclusion
The Quantex Bag-In-Box pump is engineered to meet many of the challenges manufacturers within the food and beverage industry face. It can provide a high vacuum evacuation with self-priming, whilst also being able to dispense highly viscous solutions.
