NIKUNI diaphragm pump was granted an invention patent by China National Intellectual Property Administration for its novel and unique " piston chamber hydraulic pressure linkage & propulsion mechanism".
The HP Series multi piston diaphragm pump using the present invention features compact structure, smooth operation, low friction and high efficiency. At the same time, the auxiliary pressure balancing device used in conjunction with above mechanism helps maintain stabilized diaphragm operation and extended service life and at the same time ensure zero leakage of the conveyed medium.
The HP Series multi piston diaphragm pump using this technology is suitable for transportation of various pure liquids, solvents, chemical liquids, corrosive liquids, liquefied gases, slurries and high viscosity materials; It is applicable to high-pressure filtration and separation equipment, high-pressure cleaning equipment, high-pressure cooling equipment, seawater desalination and reverse osmosis equipment, oil and gas field pressure water injection equipment, spray drying equipment, coolant feeding equipment for deep hole metal cutting equipment, high-pressure tubular boiler, multi-channel reactor and other high-pressure liquid feeding equipment that requires metering capability.
