■ Description

GDJ High Pressure Plunger Metering Pump is a precision positive-displacement pump designed for accurate dosing and controlled delivery of industrial liquids. During operation, the reciprocating plunger directly draws the process medium into the pump head and discharges a measured volume through the outlet valve.

The pump head features a straightforward and economical structure, making it suitable for applications requiring high dosing accuracy, strong self-priming performance and dependable operation. Proper selection of the plunger and sealing materials enables the pump to handle a wide range of industrial chemicals under different pressure, temperature and corrosion conditions.

Stainless steel and oxidized ceramic plungers are available. The oxidized ceramic option offers excellent hardness, corrosion resistance and wear resistance, making it suitable for aggressive liquids and continuous industrial operation. Automatic lateral centering between the plunger and seal helps reduce uneven contact and minimizes component wear.

The GDJ series offers a maximum single-head flow rate of up to 50,000 L/h, discharge pressure up to 50 MPa and steady-state metering accuracy of ±1%. Different pump sizes, liquid-end structures, valve types, sealing arrangements and pipe connections are available to meet specific process requirements.

Principle of GDJ High Pressure Plunger Metering Pump:

The working medium (yellow) is directly sucked in and discharged through the reciprocating motion of the plunger. Since both the plunger and seal are in contact with the medium, choosing the appropriate plunger material and seal form can ensure the ideal performance of the pump during operation.

The plunger pump head has a simple structure, is economical, and has high measurement accuracy. It requires good seal selection and maintenance. Automatic lateral centering between plunger and seal ensures minimal wear between them. Plunger materials include stainless steel and oxidized ceramics. Oxidized ceramics have the characteristics of corrosion resistance, high hardness and wear resistance.
