Our hydromechanical solutions
Complete assemblies to protect, store and regulate — beyond the individual component.
Water hammer protection
Water hammer is a pressure surge caused by an abrupt change in flow — a pump trip, a fast-closing valve, a power cut. Left unmanaged, it fatigues and ultimately damages pipelines, fittings and valves.
Surge vessels
A buffer volume that absorbs the pressure wave and returns fluid during the depression that follows.
- Clean water vessels
- Wastewater vessels
Water hammer air traps
Release of air accumulated at high points, which disrupts flow and amplifies transient effects.
- Double-acting air valves
- High-point installation
Water hammer accessories
Complementary devices that keep the protection assembly working as intended.
- Non-return valves
- Associated instrumentation
Industrial storage
Storage capacity engineered for industrial fluids and site utilities, sized according to the stored product, the working pressure and the constraints of the location.
Hydrocarbon tanks
Storage of fuels and lubricants for fleets, generator sets and industrial processes.
- Single or double wall
- Above ground or buried
- Gauging accessories
Compressed air vessels
Buffer capacity that stabilises network pressure and limits compressor cycling.
- Volumes matched to flow
- Safety accessories
- Automatic drain
Chlorine tanks
Dedicated storage for water treatment reagents, with protections suited to the product.
- Compatible materials
- Integrated containment
- Dosing connection
Network valves
Isolation, regulation and protection devices installed in line on drinking water, wastewater and process networks. Valve type is selected according to the intended function, diameter and working pressure.
Isolation
Isolating a section for intervention or maintenance, without draining the whole network.
- Gate valves
- Butterfly valves
- Wall-mounted valves
Regulation
Control of downstream flow and pressure, notably at dam or reservoir outlets.
- Hollow-jet valves
- Wagon & sector valves
- Actuators
Protection
Preventing backflow and unwanted air ingress on pressurised pipelines.
- Industrial check valves
- Air valves
- Network accessories
An offering built around operation
Our equipment is selected and configured to last in continuous service, with maintenance that doesn't require shutting down the entire network.
- Compliance with hydraulic and industrial standards
- Complete range for water networks, from isolation to protection
- Technical data sheets available on request
- Custom configurations to your specifications
- Engineering and manufacturing handled by the SIFEI group
- Technical support before, during and after commissioning
