IN FOCUS

In industrial vacuum processes, the requirements for smart performance management and energy efficiency are constantly increasing. For more intelligence, variability and efficiency in coating, drying and heat treatment processes, vacuum specialist Leybold has therefore developed the VARODRY VDi vacuum system with integrated VAControl CAB control. The pump systems of the new series consist of the air-cooled, oil-free VARODRY screw pumps, the dry-compressing Roots pumps of the RUVAC series as well as the VAControl CAB control for smart management of all pump processes.

With its new Hya-Duo D FL-R pressure booster system the pump manufacturer KSB has complemented its portfolio of hydrant break tank package booster sets for fire fighting. The fire-fighting system, designed in conformity with DIN 14462, uses only one main fire-fighting pump to supply hydrants installed above-floor or underfloor with up to 192 cubic metres of fire-fighting water per hour in the event of fire. The systems have been developed for supplying fire-fighting water to protect multiple dwellings, residential and office buildings, multi-storey car parks and hospitals, for example.

In applications requiring a clean central vacuum, the new standardised vacuum system NDi ensures a reliable supply. The innovation from Leybold is based on the dry-running NOVADRY screw pump, which is robust over the entire pressure range, and the integrated VAControl CAB controller for smart control.

Valves installed in drinking water transport systems have to meet stringent demands, both in terms of design and materials employed. To satisfy these requirements the KSB Group’s SISTO Armaturen S.A. in Luxemburg has launched its SISTO-16RGAMaXX diaphragm valve type series, featuring threaded sockets, a stainless steel body and a special drinking water diaphragm.

SAER contribution to sustainable development stands out in its commitments to design efficient and easy-to-maintain products. Focusing on the range of split casing pumps, SAER SKD series includes more than 80 models (flow up to 4500 m³/ flow and 300 m of head, from DN 80 till DN 500).

With the smart app operating concept, simple commissioning and extensive, individual configuration options, the new development from the valve specialist GEMÜ provides users with optimal support in control processes in automated plants.

Reliable handling of clean, solids-free fluids at low flow rates and high differential heads – this is what SERO’s side channel pumps are designed for. But SERO PumpSystems also offers a high-performance solution for liquid media that are not completely free of solids: the SRZS…CO side channel pump. It delivers full performance and highest levels of reliable long-term service even with abrasive microparticles in the flow.

Pfeiffer Vacuum introduces new multi-stage Roots pumps ACP 90, which are designed for oil- and particle free applications in the pressure range between atmosphere up to 3×10-2 hPa.

As an extension to its range of high-efficiency glandless pumps with continuously variable speed control, the KSB Group is launching the Calio Pro type series in July 2022. Available in screw-ended or flanged designs, the new pumps have been developed for recirculation systems in larger buildings, such as heating, ventilation and air-conditioning systems.
