MECHANICAL DIAPHRAGM DOSING PUMPS DMX 221 SERIES

Mechanical Diaphragm Dosing Pumps DMX 221 Series DMX 221 Series The Grundfos DMX series has proven its success in dosing applications worldwide. These pumps keep maintenance to a minimum with their durable design based on diaphragm technology and high quality motors; gives the best results in many dosing applications. The versatile DMX series offers a wide flow range, different sizes of dosing heads, a wide range of materials and accessories. Technical Specifications Model DMX 221 Capacity (lt/h) 4-115 Max.Pressure (bar) 3-16 Advantages 0.4 - 2 x 4000 l/h dosing Compact design that saves money Trouble-free and low vibration dosing Always accurate dosing thanks to diaphragm design The variation in the dosage flow never exceeds ± 1.5%, and the linearity deviation never exceeds 4%. Thus, chemicals are dosed with high precision in the exact amount required. Smooth and low-vibration dosing The advanced drive technology and gear kinematics that make up the DMX series provide smooth and low-vibration dosing without creating pressure peaks. In this way, the tension on parts such as pipes and valves is reduced and the maintenance periods of the whole system are arranged at less frequent intervals. Motors that meet application needs In the multi-purpose DMX series, high-quality motors at frequencies of 50 Hz, 60 Hz, 100 Hz (Variable Frequency Drive) are available for applications using motors with specific characteristics, and EX class or ATEX certified motors are available for required situations. Excellent choice of materials for liquid contact parts and housing The plastic housings available on the smaller DMX models provide the protection and chemical resistance required for many applications. For large models, durable bodies made of epoxy coated aluminum casting are designed to meet all application needs. Investment costs and operating costs of spare parts remain low for many years. It will not be difficult for you to choose a product that is fully resistant to the dosed chemical among the wide range of materials offered for dosing heads, valves and accessories. All parts that come into contact with the liquid must be resistant to the chemicals used. Diaphragm is produced from NBR and PTFE materials. Savings in compact design. 12 different sizes of dosing heads are available for DMX pumps. As a result of the meticulous design process, a very compact series has emerged. This compactness, which reduces material costs, also allows several pumps to be placed side by side in tight spaces. The double-bodied versions (DMX 226 and 227) are one of the most cost-effective ways to utilize tight spaces or dose two different chemicals. You can also use the additional capacity available in double-bodied versions to achieve high volumes of flow for a single chemical. Accessories keep the whole system running smoothly Various accessories designed specifically for the DMX series help optimize performance. Some of those; AR control electronics (contact signal control with multiplex and divider function, 4-20 mA control via display and keypad or stroke frequency control, low level/empty signal), integrated relief valve, dosing controller, diaphragm leak detection, automatic stroke length adjustment The servo motors are in the form of Variable Frequency Drive (VFD) PTC motors. We also supply system parts such as pressure loading valves and vibration dampers. Applications DMX series; disinfection, coagulation, flocculation, precipitation etc. It is used in the following applications for the following purposes: Drinking water treatment Waste water treatment Pulp and paper industry Textile industry Cleaning water treatment Food and beverage industry, dairy farms Cooling tower water treatment Low pressure boiler feed water treatment.
