Double-diaphragm pump ASTRAsolid (DDS)

wastewaterfor chemicalspneumatic

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
