Fisher Scientific MaximaDry® Vacuum PumpRugged Diaphragm Vacuum Pumps, Oil-Free, Low Maintenance, Reliable Operation

Oil-free, low maintenance. No more downtime to add or change pump oil. Consider a MaximaDry pump for quiet, reliable operation without the mess of pump oil, or the operating costs and environmental problems associated with water aspirators.

Corrosion resistant materials. Why worry about pump damage? The thick, solid PTFE resin heads will not peel or corrode when exposed to most aggressive solvents. The sturdy FFPM valve system handles occasional liquids without degrading performance.

Quick and easy setup. You are up and running in minutes because everything connects together without tools or fittings. All that is necessary is 3/8” ID tubing.

Compact, stylish design. For convenient access, your MaximaDry oil-free pump fits easily where you need it...on your bench or inside your fume hood. With its clean, modern appearance and quiet operation, you won’t want to hide it under your bench.

Designed and built with the highest grade, corrosion-resistant materials available, these pumps will withstand even the most aggressive gases and vapors without the risk of damaging the pump.*

The smooth, single-piece diaphragm is coated with premium PTFE. Our exclusive, high-flow valves, made of tough FFPM elastomer, enable the pump to handle liquid condensate without loss of performance. In addition, the ball-bearing, totally-enclosed fan-cooled (TEFC) motor is rated for continuous duty and never needs lubrication.

By selecting a MaximaDry pump, you are freeing yourself from the hassle of stocking, checking, changing and disposing of hazardous pump oil. Even occasional diaphragm replacement takes only a few minutes, on-site, using simple tools, saving valuable equipment down time.
