OVERVIEW

PRODUCT DESCRIPTION

The worm gear and worm structure is used to decelerate to ensure the continuous and stable work of the mechanical transmission parts; the worm gear and eccentricity are installed in the form of assembly to ensure accurate stroke distance and easy to disassemble and maintain at the same time.

The design and pipeline parallel type one-way valve interface is optional, in the one-way valve maintenance, the one-way valve can be removed separately, there is no need to disassemble the pipeline at the same time.

Hydraulic drive diaphragm, diaphragm life longer.

The built-in adjustable safety valve fully protects the diaphragm and pump head components to avoid damage due to overpressure. under normal circumstances, the outlet pipeline is not allowed to install safety valves.

Using oil bath lubrication, the driving parts have a long working life.

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

Optional pressure double diaphragm detection (local / remote) alarm.

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

Frequency conversion controller, receive external control signal, adjust stroke speed, input signal: 4-20mA analog signal.

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

 

FEATURES AND ADVANTAGES

Using oil bath lubrication, the driving parts have a long working life.

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

Optional pressure double diaphragm detection (local / remote) alarm.
