Introduction to Metering Pumps

Metering pumps are used in a multitude of industrial applications, serving as high-performance dosing pumps that precisely transfer controlled volumes of liquids. Since 1983, Fuji Techno has developed a Super Metering Pumps (SMPs) that achieves accuracy levels of ±0.1% or better. There technology eliminates pulsations in the flow of liquid, a common issue with traditional pumps. Its smooth movement of the plungers also

Fuji-Techno’s Super Metering Pumps (SMPs) consist of three key components: a pump head, an electric motor, and an advanced triple plunger system. The operation of these pumps is orchestrated by a specially designed cam that governs the motion cycle of the plungers, ensuring the high precision of the pump.

When the pump is engaged, liquid flows into the pump head through suction valves, setting the stage for the suction and discharge cycle. During this initial suction stroke, each plunger fills its designated chamber with a precise volume of liquid. As the plungers re-enter their chambers, the liquid is discharged through discharge valves. This process guarantees that the total volume delivered by the pump remains both highly accurate and consistent, meeting the rigorous demands of various applications.

A notable feature of the SMP is the harmonious operation of its plungers. Each plunger works in perfect equilibrium, with the timing of their suction and discharge cycles carefully controlled by the cam mechanism. Specifically, the first plunger begins its discharge stroke at 0°, followed by the second at 120°, and the third at 240°. This staggered action creates a continuous flow, eliminating pulsations and distinguishing the SMP from conventional metering pumps, which often struggle with flow stability.

Material Flexibility and Customization Options

Fuji Techno offers an extensive array of materials for its pump heads, significantly enhancing the adaptability of their Super Metering Pumps (SMPs) to a wide range of applications. Among the material options available, metallic heads made from stainless steel 316L, Hastelloy, and titanium are particularly noteworthy. These materials are designed for environments where corrosion resistance is paramount, ensuring long-lasting performance even under challenging conditions.

In addition to metallic options, Fuji Techno provides metal-free heads crafted from advanced materials such as PTFE and PEEK. These heads are specifically suited for applications that involve reactive liquids, where the risk of metal contamination or chemical corrosion is a concern. This diverse selection of materials empowers users to choose the best fit for their specific operational needs, enhancing the versatility of the SMPs.

Moreover, Fuji’s pumps come with a variety of customizable features designed to further optimize performance. For instance, liquid and gas purge fittings facilitate piston back-flushing, allowing for easy maintenance and improved pump longevity. Heating and cooling jackets can be added to maintain a constant temperature in the pumped medium, ensuring consistent operational conditions. Additionally, the option for customizable motorized assemblies allows clients to tailor their pumps to meet unique requirements, ensuring that every installation is perfectly aligned with specific application demands.

In summary, Fuji Techno's commitment to providing a diverse range of materials and customizable features for their SMPs not only enhances their adaptability to various environments but also ensures that clients receive tailored solutions that meet their precise operational needs. This dedication to innovation and flexibility positions Fuji Techno as a leader in the pump manufacturing industry.

Fuji Techno recently introduced a cost-effective portable unit tailored for High-Performance Liquid Chromatography (HPLC) applications. This unit comes equipped with a Hastelloy pump head, Kalrez O-rings, and diamond-like carbon (DLC) coated plungers. With a flow capacity of up to 108.6 ml/min (or 217.2 ml/min with a double head) at pressures reaching 98 Bar, this portable solution is engineered to handle aggressive chemicals while ensuring precision and reliability.

Applications and Industry Impact

Fuji Techno's Super Metering Pumps (SMPs) have become indispensable tools across a variety of applications that demand ultra-high accuracy and meticulous control. 

In continuous flow reactors, SMPs provide consistent liquid delivery without fluctuations, a critical requirement for processes that rely on stable conditions. The slow movment of their plunger also ensure the absence of cavitation, even with very low density fluids like acetone at 60°C.

This consistency, combined to its capability to work at very high pressure, is very useful in applications like additive injection within an plastic extruder. 

The semiconductor industry also benefits greatly from the precise capabilities of Fuji Techno’s pumps. They facilitate effective, residue-free cleaning of delicate electronic components, ensuring that sensitive parts are maintained without damage or contamination. Additionally, in the chemical industry, SMPs ensure controlled flow during surface coating applications, enhancing the quality and uniformity of coatings applied to various substrates.

In the realm of cosmetics, these pumps play a vital role in achieving homogeneous blending of ingredients. This precise mixing and their capacity to work with highly viscous fluids (up to 100,000 centipoise (CP) is critical for quality assurance in cosmetic formulations, where even minor inconsistencies can affect the final product's effectiveness and safety.
