ATURE HIGH PERFORMANCEMETERING PUMPS RAISE THE BAR


Metering pumps are in effect high performance dosing pumps; precision instruments used to accurately transfer controlled volumes of liquids at constant flow rates with a wide range of discharge pressures into a process or system. Typically they offer accuracy in the


region of ±1% but one company has been quietly manufacturing its own unique


bar to completely new leve design of metering pumps


and control. As long ago as 1983 Fuji Techno


Industries of Japan launched a range of innovative Super Metering Pumps (SMPs) that significantly improve performance with pumping accuracy of ±0.1% or less; they produce no pulsations in the flow of liquid. According to Andrew Fallows, managing director of Motor Technology, UK-based European agent for Fuji Techno, no other pump in the world is

Fuji's Super Metering Pumps are made up of a pump head, an electric motor and a triple plunger system driven by a specially designed cam that controls the

The plungers are designed to make

For example, the first starts its discharge stroke with the cam at 0 degrees, the second at 120 and the third at 240, ensuring constant flow with no pulsations. Specially designed suctio n and discharge valves result in smooth movement of the check balls, minimising wear to the valve seats.


This ensures high accuracy is maintained over long periods of


motion cycle of the plungers. The liquid being pumped enters and exits the pump head through suction and discharge valves, filling each of the three chambers with a precise volume of liquid as each piston or plunger withdraws on its suction stroke. The liquid is then


discharged as each plunger re-enters its chamber. The three plungers work in perfect equilibrium with each other. The timing of each plunger's suction and discharge cycle being precisely

Iain continues ‘We even investigated fitting OSHA compliant compressed air nozzles with regulated airlines as a solution, so each operator would have 2 airlines per position. One would be process air, non-restricted, and the other would be a regulated pressure with the OSHA gun. However, the problem with the OSHA compressed air gun and regulated air line is that the pressure was
