OVERVIEW

PRODUCT DESCRIPTION

It adopts reliable double cam structure, which is suitable for a variety of harsh working conditions, low noise, simple disassembly and convenient maintenance.

Oil bath lubrication, long working life of driving parts.

High-precision worm gear, worm technology, smooth operation.

Flow regulation can be realized either in downtime or in running state.

The mechanically driven diaphragm adopts a multi-layer composite structure of PTFE and elastic rubber, which is leak-free and durable.

There is no diaphragm guard plate on the material side to facilitate the passage of the material.

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

Self-cleaning one-way valve structure for easy maintenance.

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

The motor is controlled by "on / stop" mode, and the flow output is adjusted by the regulating handle.

Frequency conversion controller, accept external control signal, adjust stroke speed, power supply 220V-50Hz single-phase / 380V-50Hz three-phase, input signal: 4-20mA analog signal
