The Fuji-Techno Industries Super Metering Pumps offer precise delivery of liquid without the occurrence of cavitations (pulsation). At the heart of every Fuji-Techno Super Metering Pump is a specially designed cam that controls the motion cycle of the three plungers. The three plungers work in perfect equilibrium with each other. The timing of each plunger’s suction and discharge cycle is precisely controlled by the cam, so that the total liquid discharged from the pump is accurate and constant with no pulsations in the flow. The plungers are designed to make different motions in six stages within one revolution of the cam and in harmony with each other. For example, the first plunger starts its discharge stroke with the cam at 0°, the second plunger starts at 120°, and the third at 240°. It is this unique operation that ensures constant flow with no pulsations. An electric motor is used to drive the cam-shaft. The resulting motion of the plungers, creating suction and discharge cycles, effects the delivery of the liquid. The liquid being pumped enters and exits the pump head through suction and discharge valves.
