Water recirculation vacuum pump DESCRIPTION Made from a centrifugal pump that puises water at a high velocity through suction aspirators, creating a pump rate of 10 litres/min from each pump connection. The vacuum achieved, 5 to 40mbar is dependent on the water temperature in the reservoir. Aspirated gasses from both inputs mix in the 10 litre reservoir. Although the interior of the pump is made from stainless steel and polypropylene it is a requirement to change the water in the pump to limit any attack of any chemicals or vapours absorbed in the water. For better protection of equip-ment it is recommended to connect a "Scrubber" to wash and neutralise any corrosive gasses. The pump in-cludes an exit valve that allows the water to be circulated externally. This can be used to empty and change the water in the reservoir to form an external re-circulation of water. FEATURES Reduced water consumption. 2 independent connections, aspiration pump vacuum rate 10 litres/min. Vacuum limit: 5 and 40 mbar (dependent on water temperature). Capacity: 10 litres. Low noise level (<65dBA). Valve connections for entrance and exit of vacuum and external water recirculation. CONTROLPANEL MODEL 2 vacuum connections. 2 analogue vacuum gauges.

Made up of a "Scrubber" unit that blocks the passage of condensed acid vapours and neutralises the gas vapour in NaOH, and a recirculating water pump that provides an adequate pump rate to aspirate vapours. It is supplied with 3 Kg. acid vapours neutralizer solution.
