Metering pump consists of motor, drive end and hydraulic end. The electric motor drives the eccentric mechanism to rotate through the worm gear, and the eccentric mechanism drives the diaphragm through the push rod. The regulating mechanism realizes the flow control by adjusting the eccentric distance. Diaphragm reciprocates with preset stroke length. The diaphragm is pulled back to allow the medium to flow into the chamber through the check valve. The diaphragm is pushed forward so that the same amount of medium is discharged from the outlet check valve. Continuous suction and discharge to achieve precise transfer of medium.
Hose pump applications. Chemical: various corrosive and corrosive acid-base materials Water and wastewater treatment: lime, potassium hydroxide, sodium hypochlorite, ferric chloride, sludge, etc. Paints and dyes: Mill feed, abrasive materials, pigments and emulsions conveying
Hose in the pump body was U-shaped arrangement, when the rotating body drives the extrusion wheel back and forth, the extruding hose receives the extrusion wheel's extrusion elastic deformation, and then the inlet forms the negative pressure to inhale the slurry, through the extrusion wheel's pushing, the slurry is discharged from the outlet, forming the pressure transmission of the slurry.
