Water Recirculating Vacuum Pump, 2 Inlets, 10 L/min

The centrifugal pump drives reservoir water at high velocity through two water-jet ejectors, generating 10 L/min of aspiration flow at each inlet. Achievable vacuum level—5 to 40 mbar—depends directly on reservoir water temperature. Wetted parts in stainless steel and polypropylene.

Key specifications

• Vacuum inlets: 2 independent, 10 L/min flow rate each
• Vacuum level: 5 – 40 mbar (water-temperature dependent)
• Reservoir: 10-litre capacity
• Noise level: <65 dBA
• Wetted materials: Stainless steel and polypropylene
• Valve: Inlet and outlet for reservoir draining or external recirculation circuit

Front panel

• 2 vacuum inlet connectors
• 2 analogue vacuum gauges
• Main switch with pilot light

Typical applications

Vacuum filtration, rotary evaporation, reduced-pressure distillation, and any laboratory application requiring two simultaneous, independent vacuum lines. Closed-loop water recirculation reduces water consumption compared with conventional aspirator pumps connected to mains supply.

Maintenance and protection

Aspirated gases mix into the reservoir water—regular water changes are advisable to protect the pump from attack by collected chemical vapours. For additional protection, fitting a scrubber unit for gas washing and neutralisation upstream of the vacuum inlet is recommended. The drain valve allows rapid reservoir emptying without dismantling the unit.
