OVERVIEW

PRODUCT DESCRIPTION

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.


FEATURES AND ADVANTAGES
