If it is a plunger metering pump, one may be that the valve is stuck; second, if it is a large flow metering pump, the weight of the valve or the pressure of the spring may be too large, and the pressure at the pump inlet when the plunger is running is lower than this force, and the third is If it is self-priming, it may exceed its self-priming height;

The hydraulic diaphragm pump, as the name suggests, is a metering pump that uses a piston to drive hydraulic oil, and then the hydraulic oil drives the material on the other side of the diaphragm. The mechanical diaphragm metering pump is a mechanical transmission method, which directly acts on the diaphragm with reciprocating motion, and drives the diaphragm to reciprocate and pump the liquid with mechanical force. This way, subject to the strength of the diaphragm, generally speaking, the working pressure of the mechanical diaphragm pump is all It will not exceed 1MPa, and some well done may reach 1.2MPa. The hydraulic diaphragm pump can be used in high-pressure situations, and there is no problem with 32MPa or more.
