Daihan Circulation Aspirator Pump, 57Lit., 220V, "WEV-0095" DH.WEV0095

Circulation aspirator pump designed for laboratory vacuum applications, providing water-jet vacuum generation and external circulation for evaporators and rotary evaporators. The unit delivers a maximum vacuum of 0.098 MPa (20 mbar) and is intended for use with evaporator flasks in the 5–50 L range. The pump is configured for 220 V supply and includes multi-tap outlets and safety features to support evaporation, distillation, drying and related vacuum processes.

Key Features:

• Water bath volume: 57 L
• Rated supply voltage: 220 V
• Maximum vacuum: 0.098 MPa (20 mbar)
• Pump power: 550 W
• Flow rate: 100 L/min
• Taps: 5 outlets — 10 L/min (per single tap)
• External circulation nozzle: inner Ø 8 mm / outer Ø 11 mm; safety check valve included

Advantages:

• Multiple tap outlets allow independent or parallel connections to several evaporators, increasing laboratory throughput.
• High-capacity 57 L bath and 550 W pump power support larger-volume rotary evaporation (5–50 L flasks) with stable flow rate.
• Corrosion-resistant wetted parts and provision for external circulation enable chemical compatibility and continuous circulation for heat transfer and process control.
• Integrated safety check valve and defined external nozzle connections simplify safe installation and reliable operation.
