From accurately dosing water in to an aromat production process, to injecting additives under high pressure in to a plastics compounding machine, Motor Technology’s range of Super Metering Pumps, designed and manufactured by Fuji-Techno, offer
outstanding performance across a wide range of applications.
With flow rates from the 15ml/min to 120l/min, virtually pulsation free, Fuji-Techno’s Super Metering Pumps are an ideal solution from laboratory through to full scale production.
Fuji-Techno’s Super Metering Pumps are able to handle air and moisture reactive materials, deliver liquids under FDA compliant conditions and can be specified with metal-free wetted parts.
Accuracy and precision
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 Fuji Techno Industries of Japan has been quietly manufacturing its own unique design of metering pumps that raises the bar to completely new levels of accuracy and control.
As long ago as 1983, after years of research and development, Fuji Techno launched a range of innovative Super Metering Pumps that significantly improve performance, with astonishing pumping accuracy of ±0.1% or less!
Not only that, but because of their unique design, they produce virtually no pulsations in the flow of liquid. No other pump is able to match the accuracy and performance of the Super Metering Pump. They are most suited to applications and processes that require this ultra-high level of accuracy and control, and are quite literally in a class of their own.
They are precision instruments made up of a pump head, an electric motor and a triple plunger system driven by a specially designed cam that controls the 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 controlled by the cam, so that the total liquid discharged from the pump is highly 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.
Specially designed suction 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 operation, and eliminates the possibility of the valves themselves causing pulsations or leakage.
A variety of Pump Head materials offer additional flexibility. These range from metal heads made from Stainless Steel, Hastelloy and also Titanium to metal-free heads in PTFE and PEEK.
Typical applications include pharmaceutical and chemical processing, urethane and other resins, chromatography, explosives, food processing, film, spraying and coating applications, cosmetics line mixing for liquids, feed for extruders and water treatment.
Furthermore the pumps are available with liquid and gas purge fittings to enable piston back-flushing, extending the flexibility of the pumps and providing an air-free barrier for air or moisture reactant liquids.
Heating and cooling jackets to facilitate maintaining constant temperature in the pumped medium complete the list of options that enable us to provide a pump solution tailored to your requirements.
Also available are our Pump Drive Assemblies (PDA) and Pump Turn-Key Systems (PTS) providing additional flexibility for integration in to the customers research or production process.
New low-cost unit
Fuji-Techno has launched a cost reduced version on their portable unit for HPLC applications. The new portable unit is fitted, as standard, with a Hastelloy pump head, Kalrez O-rings and DLC coated Hastelloy plungers.
The unit, with the size 08 plungers, is capable of delivering up to 108.6ml/min at pressures up to 98Bar.
The combination of the Hastelloy metal parts and Kalrez gaskets makes this pump unit suitable for a wide range of other applications where aggressive chemicals are used.
