Diaphragm Valve VS Volumetric Pump<\/a><\/u><\/p>\n <\/p>\n This is particularly important when dosing so-called “sensitive” products such as hyaluronic acid, active ingredients, etc., or for products with high added value.<\/p>\n Diaphragm valve: 8\/10<\/strong><\/p>\n The accuracy of this system depends on the deformation of the diaphragm, which is not compatible with all types of products. Moreover, it only performs small dose dosages.<\/p>\n Volumetric pump: 10\/10<\/strong><\/p>\n Volumetric pumps guarantee very precise dosing to +\/- 1% of volumes thanks to the linearity between the rotor speed and the output quantity. There is also no drop at the end of the dosing with the re-suction system, which allows the same quantity of dosing to be repeated.<\/p>\n The maintenance costs of a material are to be included in the management of the production lines. However, it is important to estimate the reliability of the different materials and the frequency with which maintenance must take place.<\/p>\n Diaphragm valve: 8\/10<\/strong><\/p>\n Low maintenance costs but the system requires a high level of responsiveness in cleaning and maintenance when it is “required”.<\/p>\n Volumetric pump: 6\/10<\/strong><\/p>\n Quite expensive maintenance but can be planned.<\/p>\n In the cosmetics industry, many products that require dosing have a very high viscosity (mascaras, lipsticks, creams, etc.). It is therefore necessary to be able to dose them while maintaining their integrity.<\/p>\n Diaphragm valve: 6\/10<\/strong><\/p>\n This system is viscosity dependent. High viscosity products do not flow, even with high pressure. It cannot be dosed correctly without heating (which can denature the product).<\/p>\n Volumetric pump: 10\/10<\/strong><\/p>\n Volumetric pumps are independent of viscosity. They are equipped with worm technology which guarantees the ability to dose all types of liquid, viscous or even pasty products.<\/p>\n Cosmetic or pharmaceutical products can sometimes contain fillers or solid particles. It is essential for professionals in the sector to guarantee the safe delivery and dosing of these products.<\/p>\n Diaphragm valve: 6\/10<\/strong><\/p>\n There is a risk of altering the products and the charges they contain when the system exerts pressure.<\/p>\n Volumetric pump: 10\/10<\/strong><\/p>\n Since positive displacement pumps are equipped with screw technology, your products, whether loaded or not with solid particles, will be dosed without suffering any damage.<\/p>\n In the packaging industry, low shear is required in order not to alter the viscosity of the product, the active ingredients and fillers it contains, in order to respect it to the maximum.<\/p>\n Diaphragm valve: 8\/10<\/strong><\/p>\n Low shear for liquid or low viscosity products. However, high shear when the viscosity of the product increases.<\/p>\n Volumetric pump: 10\/10<\/strong><\/p>\n The volumetric pump<\/a> with screw technology allows a constant flow of product, while preserving it from any shear and avoiding any compression of the product.<\/p>\n Depending on the existing production lines, it may be essential to be able to change the products to be dosed on a regular basis. It is necessary to be able to clean the equipment on a regular basis without the complexity of dismantling and reassembling the equipment.<\/p>\n Diaphragm valve: 6\/10<\/strong><\/p>\n The cleaning time of this system is still important.<\/p>\n Volumetric pump: 8\/10<\/strong><\/p>\n Easy to clean, modular system and simple to dismantle and reassemble.<\/p>\n The guarantee of a pulsation-free deposit allows to optimize the repeatability of the dosage.<\/p>\n Diaphragm valve: 6\/10<\/strong><\/p>\n The pulsation is linked to the viscosity of the product: the higher the viscosity, the more pressure must be exerted on the product and the greater the pulsation effect.<\/p>\n Volumetric pump: 10\/10<\/strong><\/p>\n The eccentric screw system allows to create a linear flow of material whatever the viscosity of the product (even if it varies over time).<\/p>\n It is necessary to have a continuous flow of material during filling.<\/p>\n Diaphragm valve: 4\/10<\/strong><\/p>\n The diaphragm which is forced to deform, the flow is stopped when it returns to its initial position.<\/p>\n Volumetric pump: 10\/10<\/strong><\/p>\n The technology of the volumetric pumps without piston (eccentric screw) makes it possible to guarantee dosages with unlimited continuous flow for liquid and viscous products, with or without fillers.<\/p>\n Comparator _ Diaphragm valve \/ Volumetric pump Diaphragm Valve VS Volumetric Pump 1.
