Pumps & precision injection systems
For engineers and researchers working with reactive fluids, extreme pressures, or critical environments, we design custom injection and pressurization systems. Our solutions deliver precise flow and pressure control where standard off-the-shelf products fall short.
01 — The problems we solve
Every injection project has its own unique challenges. Find yours below to see how our past projects have solved similar problems.
Acid, sulphide, abrasive slurry or fragile polymer: some fluids destroy a standard pump, others are degraded by it. Materials, seals and pumping principle are chosen from the fluid.

A pulsing or drifting flow distorts the measurement. The piston has to be finely controlled over the whole useful range, including against high back-pressure or without gravity.
Delivered for
In an almost incompressible volume, the slightest temperature change moves the pressure. Regulation has to hold it for days, and the test must stay safe if power is lost.
Delivered for
An old, manual or unsupported pump can return to service. Overhauling the mechanics, renewing the controls and linking it to the lab's supervision software extends equipment that has proven itself.

03 — Our approach
Our in-house engineering team (mechanical, instrumentation, automation) supports you at every stage, from defining your requirements to on-site commissioning.
In direct discussion with our engineering team, we translate your scientific or industrial problem into a precise functional specification. This key step defines the constraints related to the fluid, pressure, flow rate, and test environment to ensure a perfectly tailored solution.
We size every component: mechanical parts, materials selection, instrumentation, and automation. Building on proven platforms or developing a new architecture, we design a system that meets the performance, safety, and integration requirements of your laboratory or production line.
Manufacturing takes place in our Morlaàs workshop, followed by a factory acceptance test (FAT) to validate every feature. We then handle on-site integration, train your teams, and provide support throughout the equipment's entire life cycle, including maintenance and upgrades.
Learn more about your project by exploring our solutions for geoscience and subsurface studies, pilot plants, and custom reactors, or discover our maintenance and retrofit services.

04 — FAQ
The equipment's longevity relies on our expertise in materials science. We select specific grades like Hastelloy or super duplex, along with suitable seals, for their proven chemical compatibility with your fluid under test conditions. This approach is validated by projects involving fluids as aggressive as concentrated sulfuric acid.
Yes, that is the operating principle of our syringe pumps. A high-precision motor directly controls the piston's displacement, generating a continuous, completely pulse-free flow. The injected volume is thus measured directly and absolutely, providing metrological accuracy even at very low flow rates or against high back-pressure.
For long-duration tests where pressure must be maintained, we design systems with a non-reversible mechanical architecture. This design makes the system self-locking in the absence of power. The pressure is thus passively maintained and your test is completely secure, as we have implemented for confining pressure applications in geoscience.
Absolutely. Our systems are designed to integrate seamlessly into your existing environment. We provide the necessary communication protocols so you can control the pump like any other instrument, directly from your supervisor. This way, you retain full control over your entire test rig.
