ASTRAsolid (DDS)

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).

  • Very high performance

  • 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

  • Dry-running 

  • Self-priming
