A great alternative to peristaltic pumps, these NSF Rotary Diaphragm pumps are capable of handling viscous materials (including those with suspended solids) without tube replacements. Here you'll find an overview of the technology, why we recommend them, and product information. As always, give us a call with any questions.
The pumping action starts with a bearing mounted to a drive shaft, which is then rotated inside a diaphragm. This rotation flexes the diaphragm, which squeezes the liquid through the pump. Self-priming, valve-less, and seal-less make this pump the ideal candidate for food safe, or NSF, pump for syrups, sauces, beverages, and other food items. Check out the video below to see how it works.
Why use rotary diaphragm technology? We recommend using Rotary Diaphragm pumps for these reasons:
• NSF Certification for food or beverage products
• Repeatable and consistent dispense volume over time
• Zero maintenance and long life
• You need a dispense with less pulsation - a smooth dispense
• Extremely viscous liquids need to be pumped
• Device does not allow for easy tubing changes
• A cleaning / sanitizing cycle is in place in your machine
• A flow rate of 2000 ml/min or higher is needed
Whether you need extremely accurate dosing, a stepper motor, a pump with PWM, 110-230V high voltage, 12-24V low voltage, brushed or brushless motors - we've got the whole RD series here. If you don't see exactly what you need, you can always contact us for a customized model.
The RD Series pumps are perfect for a sauce pump, from pizza sauce to salad dressing, ketchup to all condiments. They are great for BIB (bag-in-box) products, like soda syrup, coffee concentrate, sweet tea concentrate, or similar beverage liquids. They are also great for smoothie mixes or dairy products and deliver the dispense with smooth output. But don't take our word for it, we have a full series of videos putting these pumps through their paces.
