Key features/benefits
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).

- Optimized air consumption
- Evolved diaphragm caps
- Free-ice system that also increases the performance and keeps the air consumption low
- Optimized internal design for easing the transfer of viscous and charged liquids.
- Very-fast pneumatic exchanger
- Improved operating sensitivity (from 1 bar)
- Non-stalling
- PE1000: highly resistant material with low-friction coefficient and temperature range from -40°c to 70°c.
- modified PTFE diaphragms inert to chemical agents
- Diaphragms available in thermoplastic rubber (TPE, TPV) and reinforced elastomers (FKM, EPDM, NBR)
- Ergonomic fixing
- Easy maintenance
- Ideal for shear sensitive liquids
