JYM50 series hydraulic diaphragm metering pumps
A metering pump is also known as a quantitative pump or a proportional pump. A metering pump is a special volumetric pump that can meet various strict process requirements, with a flow rate that can be infinitely adjusted within the range of 0-100%, and is used to transport liquids (especially corrosive liquids).
A metering pump is a type of fluid conveying machinery, characterized by its ability to maintain a constant flow rate independent of discharge pressure. The use of a metering pump can simultaneously perform the functions of conveying, metering, and regulating, thereby simplifying the production process. By using multiple metering pumps, several media can be accurately proportioned and mixed into the process flow. Due to its outstanding performance, metering pumps are now widely used in various industrial fields such as petrochemicals, pharmaceuticals, and food.

Product Overview
The hydraulic end of the pump is composed of a working cavity with the help of a diaphragm, and the reciprocating motion of the plunger (piston) is replaced by the periodic deformation of the diaphragm, which is called a diaphragm pump. The periodic deflection of the diaphragm is achieved by the reciprocating motion of the plunger (piston) in the hydraulic working cavity to produce a hydraulic drive diaphragm metering pump, which is called a hydraulic diaphragm metering pump.
Functions1. No dynamic seal, no leakage, easy maintenance, with built-in hydraulic safety valve, to avoid automatic opening of the process pipeline when blocked, and protect the pump and pipeline.
2. The working pressure can reach 80MPa, and the measurement accuracy can reach 1% of soil; Single cylinder pump flow range:
0.2L/h-16000L/h.
3. The metering accuracy is better than that of the mechanical diaphragm pump, and the sealing performance is better than that of the plunger pump.
4. The flow control is realized by adjusting the stroke length and frequency conversion speed regulation, and the stroke controller, digital controller or frequency converter can realize remote automatic control.
5. The use temperature of the medium should not exceed 300 °C, should not be lower than -30 °C, and special design is required for temperatures higher than 120~280 °C.
6. The new three-valve structure (safety valve, exhaust valve, oil filling valve), in which the application of the limit oil filling mechanism avoids excessive oil replenishment, so that the life of the diaphragm can be increased to more than 8000h.
7. When conveying special media, double diaphragm with diaphragm rupture alarm device can be used to prevent accidents caused by mixing medium and hydraulic oil when the diaphragm is ruptured.Features introduced
1. No dynamic seal, no leakage, easy maintenance, with built-in hydraulic safety valve, to avoid the process pipeline blocked automatic opening, protect the pump and pipeline function.
2. When conveying special media, double diaphragm with diaphragm rupture alarm device can be used to prevent accidents caused by mixing medium and hydraulic oil when the diaphragm ruptures.
3. The sealing surface of the inlet and outlet valve is designed with a tenon and groove surface, which is more reliable.
4. The motor stands above the gearbox to effectively avoid the leakage of lubricating oil and improve the reliability of transmission.
5. The working pressure can reach 80MPa, and the measurement accuracy can reach 1% of soil; The flow range of single cylinder pump is 0.2L/h-16000L/h.
6. The flow adjustment mechanism adopts H-type sliding shaft adjustment mechanism, and the adjustment linearity is good. The flow rate can be changed by adjusting the stroke length or changing the motor frequency; For example, it is equipped with a stroke controller or a digital controller, which is convenient for automatic adjustment or remote control.
7. The new three-valve structure (safety valve, exhaust valve, oil filling valve), in which the application of the limit oil replenishment mechanism avoids excessive oil replenishment, so that the life of the diaphragm can be increased to more than 8000h.
