Laboratory vacuum pump RE 2.5

rotary vanelubricatedlow flow capacity

Overview

• High pumping speed maintained close to ultimate vacuum
• Good ultimate vacuum even with gas ballast
• Vacuum-tight at switch-off — external anti-suckback valve not required
• Large oil capacity for extended oil-change intervals
• Easy maintenance thanks to telescopic design

Short description
The single-stage RE 2.5 pumps are high-performance rotary vane pumps with an extra-compact design and low weight. They are suited to laboratory and process applications that require a low ultimate vacuum at medium gas throughput and where space and weight are constrained.

Items supplied

• Pump filled with oil and completely mounted, ready for use, with manual

Applications

• Laboratory vacuum tasks (freeze-drying, mid-vacuum distillation)
• Small-volume evacuation and gas evacuation for chambers and instruments
• Process applications requiring moderate gas throughput and low ultimate vacuum

Maintenance
Telescopic design simplifies access to internal components. Observe recommended oil type and fill levels; oil-change intervals are extended due to the large oil capacity but depend on operating conditions and gas load.
