Description

Includes

V-belts, pulleys, belt-guard, oil supply, 3-wire cord (except 01-105-1 which must be conduit wired), plug, inline switch and instructions.

Rugged, durable pumps are ideal for demanding applications such as Schlenk drying lines, freeze drying, vacuum distillations, concentrating and degassing

The ruggedness is a result of reduced frictional wear (less than 580rpm vs. typical 1750rpm direct-drive pumps) and high contamination tolerance (contaminants diluted due to large oil capacity).

  • Dual-voltage models come wired for lowest voltage listed in specifications chart; may be converted to higher voltage listed by rewiring
  • Wiring diagram supplied with each model
  • All models are single phase

1International Model for 115/230V 50Hz available on special order.
