3DP20 high-pressure pump
Pump thrust: 350kg
Pump stroke: 20mm
Pump weight: 80kg
Introduction to 3DP20 model
Suitable for professional pumps such as valve and pipeline pressure testing pumps, high-pressure cleaning pumps, metering pumps, process pumps, dosing pumps, hydraulic pumps, oil transfer pumps, etc.
Assembly types: horizontal, vertical, fixed, and mobile.
Transmission types: including electric motor, diesel engine, gearbox, pulley, electromagnetic speed regulation, and variable frequency speed regulation.
The technical parameters in the table are used as selection references. Each type of pump is equipped with a safety pressure regulating valve, and the pressure of the pump can be adjusted arbitrarily.
When selecting, if the flow rate in the table is not suitable, electromagnetic speed regulation, frequency conversion speed regulation, and changing the plunger diameter can be used to adjust the flow rate to meet the selection needs.
