LAB1ST offers SHZ-series recirculating water vacuum pumps, which are oil-free, chemical resistant and easy-to-maintain. Vacuum up to 20 mbar is generated by water flow via Venturi Effect. The pumps provide a constant water recirculation (from its water tank), which can be used for cooling condenser and drastically decreases water consumption. All major components of the pumps are made of PTFE, making them cost-effective alternatives of traditional PTFE diaphragm vacuum pumps.
There are 2 models in the SHZ-series. The SHZ-III (20 mbar, 20L/s) is a desktop model and the SHZ-95 (50 mbar, 20L/s) is a floor-stand model.
Oil-free, corrosion resistant, reliable.
All major valves and parts made of PTFE, ideal for chemical-related operation.
No oil changes, no cold trap required for water/alcohol solutions.
