MAIN PERFORMANCE
1. Voltage: DC12V/24V, AC110~120V/220~240V.
2. Maximum flow rate 6 l / min, flow can be adjusted depending on
demand from 1.0 - 6.0 liters / per minute.
3. Maximum pressure 126PSI (11bar), pressure 10PSI (0.6bar) -
160PSI(11bar) to adjust depending on the demand.
4. Tower connector-10mm connector, 3/8 "screw thread connector or
3/8" pipe joints and other joints.
5. Selectable pressure protection: pressure switch controlling
power on/off and reflux switch protection; selectable power control
without the pressure security devices. Work: intermittent
(continuous work in different work pressure for different operating
time).
