OVERALL DIMENSIONS
BX81 pneumatic pumps are characterised by their extremely small size. Their compact dimensions make them particularly suitable for installation in industrial equipment where it is necessary to handle small quantities of fluid in confined spaces. The square shape of these double diaphragm pumps is perfect for use in awkward environments, unusual positions or places that are hard to access, such as installations in batteries, installations in centralised distribution cabinets, bench-top or ceiling-mounted installations (situations that are very common in the chemical sector, in the handling of inks and paints, in printing machines and in oil circuits). BX AODD pumps also have the possibility of having split manifolds (two suctions and two deliveries).

ATEX PUMPS FOR EXPLOSIVE AREAS
BX81 pneumatic pumps hold Atex Approval for use in environments where there is a risk of explosion. The pumps are manufactured to be explosion-proof in compliance with Directive 2014/34/EU according to the harmonised European standards EN-60079-10 and EN 1127-1. It should be remembered that, first and foremost, the user of the equipment is responsible for classifying its area of use, while the manufacturer is responsible for identifying the certification class of the pump manufactured and applying the relevant ATEX marking. To meet all the requirements of the various Zones, BX81 double diaphragm pumps are available in two different versions:
| ATEX ZONE 1 – VERSION BY REQUEST | ATEX ZONE 2 – STANDARD VERSION |
|---|---|
|
BX series double diaphragm pumps are available, by request, in a special conductive version for use in “Zone 1 – Zone 21”. ATEX marking available:
|
All standard versions of BX series diaphragm pumps are suitable for use in “Zone 2 – Zone 22” (presence of gas and flammable powders). ATEX marking available:
|
VERSATILE CHEMICAL PUMPS
The construction principle of Savino Barbera double diaphragm pumps allows the problem-free pumping of dense, flammable or viscous liquids. Regardless of the liquid handled, BX aodd pumps always have an adjustable flow rate and head. They can run dry and can be installed in potentially explosive areas (requiring Atex Certification) or in particularly humid environments. Their internal exchanger (the device that introduces compressed air into the pump) is already lubricated: the air supply does not need to be lubricated and must, on the contrary, be dried and free of impurities (such as oil, dust and condensation).

AODD PUMP OPTIONAL FEATURES
Our range of double diaphragm pumps includes numerous optional features and accessories:
- Air regulation kit (filter, reducer, bracket, pressure gauge, hose, tap and fittings).
- Shock absorber (to minimise flow pulsation).
- Split manifolds (two suctions and two deliveries).
- Assembly in three different positions for both delivery and suction.
- Trolleys for portable versions (on which the diaphragm pumps can be mounted).
- Flanged connections in PP, PVDF, ALU, AISI 316 (DN15 → DN80).
