The variable eccentric mechanism mediates to ensure that the flow pulsation changes smoothly, and the new regulating mechanism makes the adjustment more accurate and reasonable.
Built-in limit oil compensation valve to ensure hydraulic oil balance replenishment; built-in adjustable safety valve to fully protect hydraulic end parts to avoid diaphragm rupture and other parts damage caused by high pressure in hydraulic cavity.
The double diaphragm with diaphragm rupture alarm device can be selected when conveying corrosive slurry, flammable and explosive and other dangerous chemicals.
Frequency conversion controller: accept external control signal, adjust stroke speed, input signal: 4-20mA analog signal.
Motor controller: control the three-phase motor in "on / stop" mode and adjust the output flow
