OVERVIEW

PRODUCT DESCRIPTION

Mechanically driven diaphragm, no diaphragm guard plate on the material side, easy for the material to pass through.

PVC, PVDF, 316SS and other pump head materials are optional, suitable for conveying all kinds of materials.

Self-cleaning one-way valve structure.

GW series: variable eccentric structure adjustment to ensure smooth change of flow pulsation; enhanced structure design, suitable for harsh operating environment.

GS series: reliable cam structure, suitable for a variety of harsh working conditions, low noise, simple disassembly, convenient maintenance.

Supported by sliding bearing, it works smoothly, reliably, without noise and low maintenance cost.

Power supply: 380V/220V-50Hz/60Hz/ three-phase / single-phase.

Motor controller: the three-phase motor is controlled by "on / stop" mode to adjust the output flow.


FEATURES AND ADVANTAGES
