3 eatures and benefits DMX Reliable diaphragm dosing from 4 to 2* x 765 l/h. ig. 1 DMX Versatility through choice The Grundfos DMX is a series of high-quality diaphragm pumps suitable for many uses, e.g. drinking water treatment, wastewater treatment (settlement/ sludge treatment), and the pulp/paper and textile industries. The range is designed to be highly versatile, a fact which is reflected in the wide flow range covered and the choice of dosing head sizes, materials and accessories available. If in doubt, ask us we will help you configure the DMX that is best for you. Tried. Tested. Truly reliable The Grundfos DMX series has proven its worth in dosing applications worldwide, demonstrating how its sturdy diaphragm-based design and high-quality motors combine versatile dosing with minimum maintenance requirements. Now updated as an integrated part of the Grundfos dosing range, the Grundfos DMX series is as trustworthy as ever. Accurate dosing. All the time The diaphragm design ensures that the dosing flow never varies by more than ±1.5 per cent. And the linearity is kept below 4 per cent at all times. Smoothness comes standard The Grundfos DMX series employs sophisticated drive technology and gear kinematics to ensure smooth, lowpulsation dosing. TM Motors to match application needs If your application involves specific motor requirements, the versatile DMX range can match that, too: Grundfos DMX dosing pumps can be configured with servomotors or Atex-class motors as required. As ever, your Grundfos consultant is happy to help you choose the right DMX for you. Choose the materials and size that suit you The smaller models in the Grundfos DMX series are enclosed in plastic which is resistant to chemicals and offers all the protection necessary for most applications. The larger models have a robust cast-aluminium gearbox with an epoxy coating to meet all application needs. You also get a choice of materials for parts that come into contact with the chemicals you wish to dose, so it is easy to get a Grundfos DMX with exactly the degree of chemical resistance you want. Large models remain compact The DMX range comprises ten different dosing head sizes, but careful design work has kept them compact, making it easy for you to connect several pumps right next to each other if necessary. Twin-head versions saves you money The two dosing heads fitted in the twin-head versions of the DMX range offers you a very cost-efficient way of dosing two different chemicals to suit your application. Of course, the extra capacity offered by twin-head versions can also be used to gain higher flow rates for a single chemical. Accessories ensure perfect system integration A wide range of accessories specially designed for the Grundfos DMX series help optimise performance. This makes commissioning fast and easy. Other accessories are also available to make sure that your Grundfos DMX fits your system exactly e.g. pressure loading valves for dosing systems with no or varying back pressure. *Only DMX model 226 is available with two dosing heads. 3

4 eatures and benefits DMH Strong piston/diaphragm dosing from 2.2 to 2* x 115 l/h. Enjoy the Teflon effect The DMH pumps can shrug off almost anything. They are fitted with Teflon (PTE) diaphragms, and the parts that come into contact with the liquids dosed are available in material combinations to suit virtually all dosing scenarios. Ready for tough applications The tough application areas within the oil refinery industry can also benefit from the Grundfos DMH range: several models have been designed and approved in accordance with API 675. *All DMH pumps are available with two dosing heads. TM ig. 2 DMH The preferred choice for complex tasks The Grundfos DMH range is a series of extremely strong, robust pumps for situations where you need a substantial dosing range and high-pressure capability. The pumps are accurate to within ±1 per cent of the rated flow, making the DMH series the preferred choice for complex tasks and automatic process integration. And their strength is a matter of public record: Customers worldwide have enjoyed years of trouble-free operation from their DMH pumps. Get the pump configuration you need A number of different product configurations are available to match your requirements. or example, you can choose between electric or pneumatic servomotors, opt for an AC inverter-controlled motor, pick special dosing heads with electrical heating, or have your pumps fitted with double diaphragms with failure indication. If in doubt, ask your Grundfos consultant to help you choose the best configuration for the task. Prepared for extreme situations AMS diaphragm protection keeps both the pump and overall application protected against extensive high pressures in the event of blockages in the discharge line. Similarly, pressure-relief valves guard the pump against excessive pressure in the system. Stroke-length adjustment ensures precise dosing Very precise and accurate stroke-length adjustment, with setting carried out using a Vernier scale, brings you optimum dosing with a repeatability of only ±1%. 4

15 Construction General description The Grundfos pumps are mechanical diaphragm dosing pumps. The strokes are generated by an eccentric which moves the diaphragm by means of a spring-loaded plunger. The discharge stroke is activated by the eccentric and the suction stroke by the spring return. The pumps are designed for capacities between 4 and 2 x 115 l/h and a maximum pressure up to 2 bar. The DMX pumps are fitted with a separation chamber. In the event of a diaphragm failure, the separation chamber prevents the pumped liquid from flooding the pump unit or other system components.

17 Construction DMH model 251 Oscillating positive displacement pumps with hydraulic diaphragm control ig. 11 Sectional drawing, DMH model 251 TM unctional principle The rotational movement of the drive motor (1) is converted via the worm gearing (2) and eccentric (3) into the oscillating suction and stroke movement of the piston (6). The piston has a hollow bore and a row of radial control holes, which provide a hydraulic connection between the drive area and the piston stroke area. The sliding plug (5) envelops the holes during the stroke and seals the stroke area from the drive area. The hydraulic excursion of the solid PTE diaphragm (1) displaces an equivalent volume of dosing liquid from the dosing head (11) into the dosing line. With the suction stroke, the piston creates a low pressure, which propagates in the dosing head; the ball valve (13) on the dosing side closes and the dosing liquid flows through the suction valve (12) into the dosing head. The stroke volume size is solely determined by the position of the sliding plug. The active stroke length and corresponding average dosing flow can therefore be changed continuously and linearly from 1 to 1% using the stroke-length adjusting knob and Nonius scale (14).

With the suction stroke, the piston creates a low pressure, which propagates in the dosing head; the ball valve (13) on the dosing side closes and the dosing liquid flows through the suction valve (12) into the dosing head. The stroke volume size is solely determined by the position of the slide valve. The active stroke length and corresponding average dosing flow can therefore be changed continuously and linearly from 1 to 1% using the stroke-length adjusting knob and Nonius scale (14).

29 Construction DMH model 288 Oscillating positive displacement pumps with hydraulic diaphragm control ig. 23 Sectional drawing, DMH model 288 TM unctional principle The rotational movement of the drive motor (1) is converted via the worm gearing (2) and eccentric (3) into the oscillating suction and stroke movement of the piston (6). The piston has a hollow bore and a row of radial control holes, which provide a hydraulic connection between the drive area and the piston stroke area. The slide valve (5) envelops the holes during the stroke and seals the stroke area from the drive area. The hydraulic excursion of the solid PTE diaphragm (1) displaces an equivalent volume of dosing liquid from the dosing head (11) into the dosing line.
