Diaphragm pump units (speed controlled)

Suitable for Rotary evaporators Hei-VAP series. Controllable vacuum pumps for digital regulation of the vacuum via operation panel or directly at the unit.

• High distillation rates and reduced process time by 30 %.
• Solvent recovery up to 99 %.
• Pump stops automatically as soon as the set vacuum is reached and reliably holds the vacuum constant
• Increased diaphragm performance life due to periods of non-operation
• Low energy consumption
• Significant noise and vibration reduction
• The pumps can be combined with a condenser

• Recommended for solvents with low or medium boiling points
