▶  Multiple professional application pump head configurations: high viscosity, slurry, concentrated sulfuric acid, sodium hypochlorite, etc

▶  Self cleaning one-way valve structure

Main features of the driver end

▶ Variable eccentric mechanism adjusts stroke length to ensure smooth flow pulsation changes

▶ Enhanced structural design, suitable for pulsating impacts and harsh operating environments

▶ Sliding bearings and high-strength worm gear and worm gear ensure long-term stable operation

Flow regulation method

Manual adjustment: adjust the stroke length with the handwheel

▶ Flow regulation can be achieved regardless of whether the pump is running or stopped

▶ The minimum adjustment scale is 1%

Electric stroke controller: receives external control signals and adjusts stroke length

▶ Power supply: 220V-50Hz - single-phase

▶ Input signal: 4-20mA analog signal

▶ Output signal: 4-20mA/1-5V analog signal, for recording, display, and control system use

Variable frequency controller: receives external control signals and adjusts stroke length

▶ Power supply: 220V-50Hz single-phase/380V-50Hz three-phase

▶ Input signal: 4-20mA analog signal
