Diaphragm Pumps
Diaphragm pumps are a type of pump used when transferring liquids that operate of compressed air from compressors. They are composed of membranes called diaphragms and 2 check valves. They have simple structures, so maintenance and disassembly are relatively simple, and a feature of this pump is that transport and setup can be done relatively easily. Suction and discharge of liquid are done in an alternating sequence, so liquid flows intermittently. Liquids with high viscosity and liquids that contain abrasives can be transferred easily by pressure feeding with high pressure. Liquids can be transferred without changing their properties and there is no leakage, so chemicals, solvents, and the like can be transferred safely. You can select from self-priming, electric, manual, and air types, and there are also types where discharge volume can be adjusted. Check valve sealing properties greatly affect pump performance, so caution needs to be taken to prevent the entry of contamination and the like and to keep the check valve from drying out.
