OVERVIEW

PRODUCT DESCRIPTION

Variable eccentric structure adjustment to ensure smooth change of flow pulsation.

Enhanced structural design, suitable for harsh operating environment.

Wear-resistant ball bearings make the work more stable.

Oil bath lubrication, long working life of driving parts.

The flow rate can be adjusted under the condition of stopping or running, and the adjustment mode can be dynamic, electric or frequency conversion.

Mechanical drive diaphragm, there is no diaphragm guard plate on the material side, which is convenient for the material to pass through.

PVC, PVDF, 316SS, high viscosity, slurry and other pump head materials, suitable for conveying all kinds of materials.

Self-cleaning one-way valve structure, easy to maintain.

The electric stroke controller receives the external control signal and adjusts the stroke length.

Power supply: 220V Mel 50Hz-single phase.

Input signal: 4-20mA analog signal.

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

Frequency conversion controller: accept external control signals and adjust stroke speed.

Power supply: 220Vmur50Hz-single-phase / 380V-50Hz-three-phase.

Input signal: 4-20mA analog signal.

Motor controller: control the three-phase motor in "on / stop" mode and adjust the output flow.

Power supply: 200-240V/50Hz/60Hz/ single phase.

Control mode: can accept 4-20mA analog signal, external pulse signal or manual adjustment
