Vacuum Diaphragm Pump Systems LVS with economic (en) control

 one automatically regulated connection

 one automatically regulated connection, for network

economic uses the same two point control system, but replaces the control
valve with a relay which turns the pump on and off to maintain the process
vacuum between the user defined vacuum and hysteresis levels. This method
greatly reduces power consumption and extends the lifetime of the pump.

Suitable for: multi-user vacuum network
