Both stages use a water jacket for cooling. Versions with once-through water cooling and water circulation are available. The cooling jacket controls the pump operating temperature needed for the specific application. The once-through water version controls the temperature by controlling the water flow with a temperature-controlled valve. The recirculating coolant version uses a thermostat to control the pump temperature.
- high vacuum level
- extremely robust and reliable
- easy servicing
- suited for conveying acid vapors and monomers or products that lead to polymerization when other vacuum technologies are used
- operating fluids must be treated or correctly disposed of
It is important to consult with a vacuum expert and consider process conditions, process gases and integration into process control, as well as economic efficiency, safety and reliability. Often, these factors lead to a customized vacuum system that is tailored to the requirements.
