| GX Series Mechanical Diaphragm Metering Pump | 2GX Series Mechanical Diaphragm Metering Pump |
Mechanical drive diaphragm, no diaphragm guard plate on the material side, easy for materials to pass through, PVC, PVDF, 316SS and other pump head materials are optional, self-cleaning one-way valve structure.
Variable eccentric structure adjustment, to ensure that the flow pulsation changes smoothly, suitable for a variety of harsh working environment; flow adjustment can be achieved in downtime or running state.
Using oil bath lubrication, the driving parts have a long working life.
When selecting the 2GX series, two different media or one medium can be transported at the same time; the double-head flow rate can be adjusted separately, and the adjustment range is larger; compared with the single-head pump pulse, the pulse can be reduced by 50%, the transportation is smoother, the motor utilization efficiency is higher, and the performance-to-price ratio is higher.
Power supply: 380V/220V-50Hz/60Hz/ three-phase / single-phase.
Frequency conversion controller, receive external control signal, adjust stroke speed, input signal: 4-2mA analog signal.
The motor controller controls the three-phase motor in the "on / stop" mode and adjusts the output flow.
