DY Series Hydraulic Diaphragm Metering Pump

Hydraulic diaphragm metering pump is a type of pump equipment commonly used in the industrial field. It works using the hydraulic principle and realizes liquid transportation through pressure difference. This type of pump usually consists of a hydraulic drive system, a diaphragm assembly and a metering device. It is characterized by safety, no leakage, no noise, small size and simple operation.

Diaphragm metering pumps work by using compressed air or hydraulic force to expel liquid from one chamber and then draw it into another chamber. The two chambers are separated by a flexible diaphragm. When the pressure increases, the diaphragm is pushed toward one chamber, thereby pushing out the liquid. When the pressure decreases, the diaphragm moves toward the other chamber, allowing it to be sucked in. liquid.

Hydraulic diaphragm metering pumps are commonly used in applications that require precise control of liquid flow and pressure, such as in the chemical, petroleum, pharmaceutical and food processing industries. They are generally capable of handling various types of liquids, including corrosive liquids and highly viscous liquids.

Product Features

• Advanced hydraulic system design, safe and leak-free.

• The flow rate of the pump can be adjusted in both running and stopped states.

• No noise, small size, simple operation and convenient maintenance.

• It can operate safely even when there is no medium in the pump head.

• The operating temperature of the medium should not exceed 100°C and not be lower than -30°C, otherwise the service life of the diaphragm will be affected.

• In order to prevent accidents caused by the mixing of medium and hydraulic oil after the diaphragm ruptures, a double-diaphragm metering pump with a diaphragm rupture alarm device can be used to transport flammable, explosive, highly toxic and precious liquids.

Scope of application

• Can quantitatively transport acid, alkali, water, suspended liquid and various special media.

• Suitable for normal room temperature water and even liquids that are highly corrosive, volatile, easily crystallized, flammable, explosive, highly toxic, highly corrosive, radioactive or other valuable liquids, etc.
