ARGAL s.r.l. AODD Thermoplastic ASTRA Pumps DDA 75

Sturdy construction with pumps casings, manifold and central casing to host pneumatic distributor and actuator, made exclusively by injection molded reinforced technical polymers.
All parts assembled with interposition of static O ring seals and SUS bolts.
Pump conceived from the drawing board to deliver esily and economically several optional features.

Pneumatic distributor and actuator made up by;

• Astable pneumatic distributor, air spring assisted.
• Command valve coaxial to the shaft linking the diaphragms;
• Bidirectional valve to control air flow to and from air chambers.
• Metal free, advanced pneumatic distributor easily accessible from the outside does not require disassembling the pump to be inspected.
• Normal” pneumatic distributor or “Progress” performance regulation” feature.

Options on request:

• Air supply circuit connection to pneumatic distributor separarte and independent from air supply circuit actuating the diaphragms;
• Connection to detect pumping cycles;
• Connection to pick up the diaphragm position pneumatic signal;
• Connection for remote air discharge;
• Submerged pump configuration.

Sturdy constructed die cast injection molded, welds free, aluminium alloy pump casings and manifolds.
All parts assembled with interposition of static O ring seals and SUS bolts.
