Vacuum Diaphragm Pump V-600 Item ID: BUC11V600000

The powerful and quietly operating three-stage PTFE diaphragm vacuum pump is robust and chemically resistant. It operates at the maximum flow rate of 3.1 m3/h and achieves an ultimate vacuum of 1.5 mbar. Thanks to its high flexibility, the Vacuum Pump V-600 can be integrated effortlessly into any BUCHI laboratory or industrial evaporator for utmost efficiency.

Benefits

Convenient

• Quiet and smooth operation thanks to speed regulation
• Unattended and safe operation with alerts for potential overflow of the receiving flask, when combined with optional level sensor

Robust and reliable

• High chemical resistance thanks to supreme quality materials
• Increased lifetime by speed-controlled operation in conjunction with the optional Interface I-300 / I-300 Pro
• Easy visual detection of condensate and particles through transparent front panel

Extendable

• Seamless plug & play integration into:
  • a laboratory Rotavapor® R-300 system with one or two rotary evaporators
  • an industrial Rotavapor® R-220 Pro system for large volume
  • a parallel evaporation system Syncore® or Multivapor™ for simultaneous evaporation of multiple samples

Features

Speed control

Speed control allows for the precise achievement of the set vacuum, while avoiding sudden pressure changes and minimalizing bumping effects.

Quiet operation

Smooth functioning at low noise levels (40 dB) is guaranteed thanks to speed-control to keep the set vacuum.

Easy particle detection

Pump membranes are visible through the transparent front panel enabling easy detection of condensed solvents or particles.

Increased safety

The optional level sensor, combined with the Interface I-300 / I-300 Pro, alerts the operator to empty the receiving flask when required.

Clean emission

The optional secondary condenser captures vapor preventing uncontrolled release into the laboratory atmosphere.

Seamless integration

The plug & play feature ensures easy integration into any BUCHI evaporator system and direct control from the central interface enhances usability.

Expert Advice

How can I reduce the noise emission of a vacuum pump?

By choosing a speed-controller pump. The Vacuum Pump V-300 / V-710* in conjunction with the Interface I-300 / I-300 Pro are operating only when required. This significantly reduces the noice emission and extends the lifetime of the pump.

*V-710 reqires the LegacyBox for speed-controlled operation.

What is the advantage of the secondary condenser compared to an in-line condenser between pump and distillation unit?

If the solvent is expanded first to ambient pressure, the vapor pressure is increased and thus a condensation much more efficient. This is the reason why the secondary condenser is at the pressure side of the pump. Due to the chemical resistance of the diaphragm pump, even aggressive gases and vapors do not harm the pump.

How do I efficiently use the gas ballast?

The gas ballast is an easy method to adjust leakage air to the pump heads. This addition of inert gas helps to dry the diaphragms in case of condensate and thus increase the pump rate again. Typically, the gas ballast is closed to obtain highest flow rate.

How can I reset the power save mode?

The power save mode mode can be reset by simply switching the pump off and on again.

Why are there some condensate droplets on the diaphragm?

If the distillation parameters are not chosen according to the "delta 20 rule" (10-30-50), the condensation is not complete and vapor is entering into the pump. Due to the high vacuum in the second stage, the vapor may condensate, leading to droplets. Thus, the pressure has to be increased or the cooling temperature of the condensation assembly decreased.

Is the final vacuum affected by the power save mode?

No, the final vacuum is not affected by the power save mode. It only reduces the speed of the pump which reduces the capacity after 1 hour to 1.6 m3/h and after 2 hour to 1.0 m3/h.
