ARGAL – Diaphragm Pump ASTRAsolid DDS 650

Diaphragm Pump

ASTRAsolid, the ideal solutions for transfer operations of abrasive, corrosive and charged liquids.

ASTRAsolid (DDS) pumps share the same constructive and performing advantages as ASTRAevo pumps: a fast pneumatic exchanger increased unloading systems for performance optimization (without interfering on air consumption), and an optimized internal design for viscous and loaded liquids. They are made of UHMW-PE solid-block and available in size 1/2″ – 1″ – 1 1/2″ – 2″.

Why offering UHMW-PE solutions? ASTRAsolid pumps are not substituting but completing our current ranges. Thanks to the Ultra High Molecular Weight Polyethylene made from solid-block, ASTRAsolid pumps ensure a very high abrasion and corrosive resistance. They can operate continuously in in- or outdoor applications (with low temperature) and into explosive atmospheres (Ex-proof Zone 2).
