Determine the working condition of the medium: Large particles are not allowed to appear in the medium conveyed by the plunger pump, otherwise it may cause work failure. Stainless steel plunger pumps should be selected for occasions with requirements for iron pollution, and anti-corrosion plunger pumps should be selected for acidic or alkaline media.

Determine a reasonable flow range: The nominal flow rate of the plunger pump model should consider an appropriate margin range when selecting.
Determine the applicable pressure rating: The rated pressure of plunger pumps can reach a high level, but the appropriate pressure rating should be selected according to actual needs. When using a filter press, a variable displacement pump should be selected, and a low-pressure pump should be used for slurry transportation to reduce waste.
Regular maintenance and upkeep: In order to maintain the good performance and extend the service life of the plunger pump, regular maintenance and upkeep work is required. Check whether there are sudden changes or abnormalities in the inlet and outlet pressure; Check whether the lubricating oil pressure is normal and whether the temperature rise of each friction part is abnormal; Replace lubricating oil and clean oil filters and other components according to the recommended cycle in the user manual; Check and replace severely worn components such as plungers, valves, etc.
