The SD and TDV accessories are hydraulic kits for centrifugal pumps. They stand out from traditional solutions by their simplicity and speed of installation. The SD and TDV are installed directly on the pump flanges. These accessories combine several functions in a single component, which represents a significant gain for installers.
The SD has been designed to ensure a laminar flow at the pump suction port and eliminate the needs for a straight length of pipe according to the 5D rule. But this design also makes it possible to eliminate other elements of a traditional installation, such as the elbow, the Y strainer which is integrated in the SD, the pipe reduction between the pump and the suction pipe, the upstream/downstream pressure tapping port to measure the filter clogging rate and of course it eliminates multiple welds.
TDV’s are just as versatile, integrating a non-return valve, an isolation valve, and a balancing valve in one and the same elbow or straight part, depending on the type of pump. The TDV also acts as a reducer to accommodate the difference in diameter between the pump and the piping. The presence of pressure tapping ports, upstream/downstream of the valve allows a measurement of the flow.
SD diffusers are compatible with vertical in-line pumps, horizontal pumps and axially split-case pumps.
TDV-A multifunction valves are compatible with vertical in-line pumps and axially split-case pumps.
TDV-S multifunction valves are compatible with horizontal pumps. Their straight shape suit their vertical discharge.

SD
ELIMINATE THE STRAIGHT LENGTH OF PIPE THE PUMP SUCTION LINE
The SD accessories are mounted directly on the pump suction flange. Its diffusion cartridge ensures a laminar flow. The SD is included in the flow conditioning solutions on pump suction line, according to the recommendations of the CEN/TR13932, ISO5167 and ISO7194 standards and allow for the removal of the straight length of pipe in the pump suction line.
TDV
MULTIFUNCTION VALVE – 3 IN 1
The TDV accessories are mounted directly on the pump discharge flange. The valve integrates 3x functions in one piece, a check valve, an isolation valve and a manual balancing valve.
Our SD and TDV accessories are intended for HVAC and industrial applications, in closed or open loop circuit. They are suitable for pumping clean water. SD and TDV are available in grey cast iron, ductile iron, steel and stainless steel, with diameters up to DN600, for working pressure ranges up to 40 bar.
Our SD and TDV low footprint in pump assemblies application makes them an ideal choice in cramped plant rooms, for the manufacturing of pump skids or for integration in packaged products for OEM customers.
Our SD and TDV accessories are used in a wide variety of market sectors wherever heat transfer fluids are pumped. We collaborate with consultants and contractors who have enabled us to demonstrate the added value of our products. Our SD and TDV have been in operation for several years in office buildings, shopping centres, residential, educational and leisure buildings. We are also present on more critical sites, such as datacentres or pharmaceutical production sites.
Several contractors, consultants and facility management companies have already shown their confidence in our solutions by integrating our SD and TDV into their designs. We supplies our products beyond our national borders and export a large portion of our production.
