The hydraulic end of the pump forms the working chamber with the help of a plunger, and the volume of the working chamber is periodically changed by the reciprocating linear motion of the plunger.

Define
the pump that the hydraulic end of the pump is composed of a working chamber with the help of a plunger, and the volume of the working chamber changes periodically in the reciprocating linear motion through the plunger.
Features
1.The plunger diameter can be made very small, but not too large, generally D=3- 200 mm.
2. The piston pump uses a wide range of discharge pressure, and should be made into a high-pressure pump.
3. It can convey high-viscosity media, and is not recommended for conveying corrosive slurries and hazardous chemicals.
4. The shaft seal is a packing seal, there is leakage, the packing needs to be adjusted periodically, and the packing and plunger are a pair of wearing parts.
5. The flow rate is in the range of 10% -100%, the metering accuracy can reach ±1%, the maximum pressure can reach 80MPa, and the flow rate is almost unchanged when the outlet pressure changes.
6. Without a safety relief device, it is recommended to install a safety valve on the outlet pipeline of the pump.
7. Simple structure, easy maintenance, good cost performance.
8. All piston metering pumps can control the flow rate by adjusting the stroke length (the stroke regulator can be automatically adjusted) and changing the motor frequency, which can be remotely controlled.
It is widely
used in chemical, petrochemical, metallurgy, electric power, medicine, food, plastic foaming, mining machinery and other fields, and has become a modern industry to achieve semi-automatic and fully automatic operation

An indispensable type of pump. It is especially popular in the process of conveying various liquid media with high viscosity, high pressure and high temperature.
Performance characteristics descriptionThermal
insulation jacket plunger pump head, with thermal insulation sandwich shell on the liquid cylinder body, inlet and outlet, can carry out special thermal insulation or cooling for the conveying medium, and control the heating or cooling effect by conveying thermal insulation liquid or coolant to the jacket.
It can also be specially designed according to the user's process needs, and is suitable for medium transportation that is easy to crystallize and needs to be kept warm or cooled.
