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 resistance material with low friction coefficient and temperature range from -40°c to 70°c.
• TFM 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

Applications

• Ceramic industry
• Metal and precious metal treatments
• Water and wastewater treatments
• Seawater and corrosive applications
• Heavy-duty applications with abrasive agents

ASTRAevo is a recent project, conceived with the latest technologies to guarantee higher reliability of the pump, a longer life cycle of the diaphragms, reducing at the lowest the maintenance necessities, and a great quality/price ratio.
