Strength points Why choose a diaphragm pump? RAASM pneumatic double-diaphragm pumps (ratio 1:1) are designed and manufactured for pumping a wide range of fluids even with high viscosities and with suspended solids. In being ATEX certified, they can also be used for heavy applications such as in places with high humidity or with potentially explosive atmosphere. We summarize below the main advantages: • Atex certification available • The wide range of materials used for the pumps makes it easy to identify the model having the best chemical compatibility with the fluid to be pumped and for the work environment...

Ball valves designed to guarantee the total flow of the pumped fluid. In the polypropylene and aluminum versions the ball seats are in stainless steel AISI 316 (1”) or in stainless steel AISI 316 and polypropylene (1/2”) Total flow suction and delivery manifolds, to facilitate suction of the liquid in any situation, with threaded connections or flanged available in different diameters according to the pump models. In the polypropylene and aluminum versions there is a stainless steel AISI 316 ring to reinforce the thread. Diaphragms designed and produced with different materials according to the...

Diaphragm pumps R. 1:1 for transferring fluids, made from molding injected polypropylene with motor made in aluminum; they ensure lasting and reliable operation even in extreme conditions and with agressive fluids. Note: The max flow rate shown in the below graphics has been obtained by laboratory test. * With PTFE membrane flow rate is 10 % lower ** Displacement per cycle may be influenced by suction lift, fluid viscosity, air pressure, number of cycles per minute *** The materials in contact with the fluid, and the fluid as well, can restrict the pump working temperature PUMP DIMENSIONS PUMP...

Exploded view of the pump, showing its main parts and thereby facilitating the choice for a custom configuration. MOTOR INNER FLANGES The table summarises the pump configurations available, allowing the user to create his own personalised code whenever the models listed on the leaflet do not meet the specific requirements. PARTS IN CONTACT WITH THE FLUID BALLS SEATS Two types of Atex certifications are available, for zone 2 or for zone 1, depending on the materials making up the pump. II 3GD c TX (for zone 2) II 2GD c IIB T4 X (for zone 1) The valve seats are to be coupled to the balls and must...

INSTALLATION AND OPERATION SIMPLE AND EFFECTIVE (1:1 RATIO) 2 The slide valve of the air motor sends air (blue) to the left chamber which, pushing the membrane outwards, compresses the previously filled liquid (green). Through the effect of the pressure created valve 1 closes and valve 2 opens allowing the liquid to dispense (green). The right membrane then carries out the same movement by the shaft joining it to the left membrane, creating a vacuum. Through the effect of the vacuum, the valve 3 opens and the valve 4 closes, enabling suction of the liquid (orange). The slide valve of the air motor...
