Stable Operation of Snowate Mechanical Diagram Metering Pump

The Snowate mechanical diagram diagram metering pump employs a mechanically driven diaphragm reciprocating mechanism to achieve precise liquid transfer. Its core structure isolates the medium from transmission components via an elastic diaphragm, ensuring leak-free operation, corrosion resistance, and high-pressure performance. It is suitable for handling strong acids/alkalis, high-viscosity fluids, and particle-laden media. Featuring adjustable flow control through manual stroke adjustment or frequency conversion, the pump offers 0–100% regulation range with ±2% steady-state accuracy., meeting the high-precision dosing requirements in chemical processing, water treatment, and pharmaceutical applications, and other industrial sectors.

GX Series

GX diaphragm metering pump is compact, energy saving, provides high precision metering, and is a high quality metering pump. The pump comes in three models, with a maximum displacement of 400 L/h. The diaphragm of GX diaphragm metering pump is made of EPDM with glass fiber, injection molded steel core, and the contact surface with the medium is PTFE. The pump uses a turbo pole reducer, a motor power of 0.25 kw, a three-phase voltage of 380 volts and a frequency of 50Hz. Depending on the different chemical media, the pump head material of the pump can use PVC, stainless steel or PVDF. Optional explosion-proof motor or variable frequency motor.
