Einstufige A-Reihe

• Schlichtes Design, robuste Konstruktion
• Gefertigt für die schwersten, industriellen Bedingungen
• Unique design allows pump to operate flooded, without damage
• Flat power curve over entire vacuum range prevents motor overload
• kein Kontakt zwischen arbeitenden Komponenten im Gehäuse
• Herunterfahrbar auf 29 Zoll Hg – 25 Torr (33 mbar a)
• Increased water handling capability prevents heat build-up, extends life of single mechanical seal
• reduziert die Beanspruchung von Motorwelle und Lagern
• Available in stainless steel, bronze, or cast iron (A200 & A300 models available in cast iron)
• Compact, close-coupled design eliminates need for interstage manifold or motor alignment  

A Series pumps are not as susceptible to cavitation compared to flat plate design because the flow path through the pump is an axial flow. This allows the velocity through the pump to be unchanged and carries the air out effortlessly.

It is not unusual for these pumps to run 24/7 operation for years without maintenance.

A Series pumps are vibration-free and environmentally friendly with no oil used for lubrication, and no oil discharged to atmosphere.

Complete, self-contained systems including liquid recovery and recirculation are available.

• Combine high pumping speed with deep vacuum levels and operate free of oil, water or other sealing liquids
• Flows range to 4,500 CFM (7646 m3/h) with vacuum levels to 10 microns and below Complete engineered solutions are available and may include any combination of dry screw vacuum pumps, vacuum boosters, electric motors, direct of V-belt drive, coolant recirculation  systems, instrumentation, controls, skid piping and valves.

• Pump high volumes at very low pressure
• High-capacity dry rotary lobe vacuum booster is matched to a smaller rotary piston vacuum pump
• For continuous operation below 1 Torr (1.3 mbar a), the vacuum booster can increase pumping speed by a factor of 10 or more
• For operation at higher pressure and for faster evacuations, the booster may be approximately twice the capacity of the piston pump
• Performance ranges 200-12,000 CFM (340-20,388 m3/h) with ultimate vacuum levels as low as 0.2 microns
• Conventional systems with direct driven or V-belt driven boosters
• Low-profile systems with close-coupled boosters are available
• Creates a higher capacity system with economy of scale
