ADB Series Air Operated Diaphragm Pumps
 
 
ADB series - Advantages and technical features
 

ADB and mini diaphragm pumps are known for their high performance, power and sturdiness that make them suitable for pumping fluid with a very high apparent viscosity, of up to 50.000 cps (at 20C) even when suspended solid parts are present.

The dry suction capacity from considerable suction heights when the pump is not flooded, together with the possibility to fine-tune the speed without a loss in pressure, flow rate and head, and the possibility of loadless operation without causing any damage, make these pumps extremely versatile.

The vast choice of composition materials allows you to determine the best chemical compatibility with the fluid and/or the environment without neglecting the temperature aspect.

Their construction makes them particularly suitable for severe environments with high humidity or in potentially explosive environments (ATEX certification).

 

Advantages

  • Self-priming
  • Non-lubricated air supply
  • Speed fine tuning while maintaining pressure high
  • Explosion-proof characteristics (to Atex II 3G. On request Conduct II2G)
  • Overhead versions available
  • Adjustable delivery and head
  • Splittable manifolds
  • The delivery and suction connections can be positioned in three different ways
  • Can run dry without damage
  • No electrical connections
  • Easily replaceable components
  • Simple and easy maintenance
  • A Conduct version to ATEX II 2G Eex c IIB T4 is also available

 

Description

Diaphragm pumps are composed of a coaxial centrally housed pneumatic motor, with new generation diaphragms (Long Life profile) fixed to the shaft. At the two ends, the two pump bodies house the ball valves and the relative seats of the product intake and delivery ducts.

  • A = ball valves
  • B = pumping chamber
  • C = diaphragms
  • D = intake manifold
  • E = delivery manifold
  • F = pneumatic motor


Coaxial pneumatic exchangers

The pneumatic exchangers that ALPHADYNAMIC has developed and innovated in a revolutionary manner, patenting the most reliable and long-lasting system available today, are the heart of the pneumatic diaphragm pumps. The device is pneumatically unbalanced thanks to a stallprevention circuit that ensures optimum operation even in the most critical conditions.

 

The diaphragms

Diaphragms are the parts that are most affected and stressed by the suction and pumping process, during which they must also resist to chemical aggression and fluid temperature. Therefore, evaluating and choosing the diaphragms correctly plays an important role in extending the life of the diaphragms and affects investments and maintenance costs. Thanks to a modern design process, destructive tests and thorough analyses of the results, ALPHADYNAMIC has developed a new generation of diaphragms called LONG LIFE that offer, thanks to their profile and construction, a greater work surface and an improved load redistribution that reduces material stress and yield to a minimum.

ATEX compliance

ALPHADYNAMIC has deposited the documentation with TUV NORD that attests ATEX conformity in accordance with the 94/9/CEE directive for BOXER Diaphragm Pumps and for as described in the following table.

They are produced in the STANDARD version, class II 3/3GD c IIB T 135C or, on request and with a suitable composition, in the CONDUCT version, class II 2/2G c IIB T 135C.

It is the user's responsibility to classify the zone of use; the manufacturer of the component must identify and label the equipment produced in accordance with the relevant certification class.

The user is responsible for classifying the area of use,
while identifying the equipment category is responsibility of the manufacturer.
