PUMPS, VALVES & ACTUATORS GO WITH THE CONTROLLABLE FLOW
motec says its Super Metering Pumps (SMPs) redefine what is achievable in continuous flow applications

n an era where process efficiency is dictated by precision, flow control technology has become a critical differentiator. Nowhere is this more evident than in the performance of Super Metering Pumps (SMPs), where both flow rate range and dosing accuracy directly influence product quality, consistency, and scalability.
The SMP offering within motec’s ControlinFlow range represents a step change in both parameters, redefining what is achievable in continuous flow applications. At the core of the SMP’s capability is its accuracy.
Traditional metering pumps typically operate at around ±2% accuracy. By contrast, Fuji Techno’s SMP technology delivers accuracy of ±0.1% or better – an order of magnitude improvement. This level of precision is not incremental; it fundamentally alters process reliability. In applications such as micro-reactors, mixers, pharmaceuticals, or high-spec coatings, even minor deviations in dosing can compromise outcomes. SMP technology eliminates that variability, ensuring repeatable, controlled delivery of fluids under varying process conditions.
Stable flow volume This accuracy is not affected by variations to external factors like pressure or fluid viscosity. The SMP maintains a stable flow volume even when suction and discharge conditions change, ensuring consistency across dynamic operating environments. This stability is critical in modern continuous processing, where systems are expected to operate without interruption and without recalibration.
Flow rate capability is equally significant. The SMP range spans from as low as 0.13ml/min to as high as 235.6l/min, covering laboratory-scale research through to full industrial production. This breadth allows a single pump technology to be deployed across the entire lifecycle of a process – from development and pilot stages to scaled manufacturing – without compromising on performance or requiring a change in equipment philosophy.

As industries continue to shift towards continuous processing and demand tighter tolerances, the importance of precise, stable
flow control will only increase What differentiates the SMP further is its ability to combine this wide flow range with adjustable, highly accurate dosing. The flow output is directly proportional to pump speed, enabling precise control over dosing volumes in real time. This proportionality provides engineers with a predictable and linear control mechanism, simplifying integration into automated systems and enabling fine-tuned process optimisation.

Underlying this performance is a triplex plunger design, driven by a precisely engineered cam system. The three plungers operate in a phased sequence, ensuring continuous discharge with virtually no pulsation. The elimination of pulsation is not merely a mechanical refinement; it directly contributes to dosing accuracy and process stability, particularly in sensitive applications where flow disturbances cannot be tolerated.
High accuracy and scalable flow range The combined effect of these design elements is a pump that delivers both ultra-high accuracy and a scalable flow range without compromise. Critically, there is no known alternative pump technology outside of Fuji Techno’s SMP range that achieves this level of accuracy, while also supporting such a wide and controllable flow rate with adjustable dosing. SMP technology positions itself not as an incremental improvement, but as a necessary tool for modern process engineering – where accuracy, repeatability, and scalability are non-negotiable.
