CIRCOR Buys Green Silence Group for Low-Noise Hydraulic Pumps

A Massachusetts flow-control group is adding an Italian quiet-pump specialist to its roster. CIRCOR announced on November 3 that it has agreed to buy Green Silence Group S.p.A., an Italian maker whose catalogue spans hydraulic pumps, electric motors and engineering services. The transaction pulls three brands — Settima, Motive and Spin — under the CIRCOR umbrella and is slated to complete in early 2027.

Under the Settima name, the target builds three-screw pumps and units engineered for whisper-quiet operation; Motive contributes motor production, and the group also develops motor designs that reach high efficiency without rare-earth magnets, alongside power electronics and engineering services. CIRCOR chief executive Saif Siddiqui positioned the purchase as a move to deepen the industrial business, noting it reinforces the company's pump lines for industrial and power generation customers while extending capability into mobile equipment. Green Silence's workforce will fold into CIRCOR's European industrial pumps organization after completion and will also gain entry to CIRCOR's employee ownership scheme, so staff share in the value the business creates. CIRCOR adds that the Italian group gains its global sales and operational reach — a route to faster international expansion and new markets.

Ultra-low-noise hydraulics are a niche with real teeth. Noise limits on vessels, offshore installations, building hydraulics and mobile equipment keep tightening, and a quietly running three-screw pump often decides whether a hydraulic power unit can sit near crew quarters, hospital wards or operator cabins without costly acoustic enclosures around it. For CIRCOR, whose valve and pump lines already serve marine, industrial and energy buyers, pairing low-noise pump modules with the existing portfolio shortens the path to quieter integrated fluid systems. The rare-earth-free motor angle deserves separate attention. Rare-earth magnet supply has become a strategic risk for motor manufacturers, and a credible high-efficiency motor line built without neodymium or dysprosium reduces exposure to export controls and raw-material price swings. Procurement teams drafting hydraulic or motor packages over the next couple of years should watch this closing closely: two overlapping vendor lists are about to merge, which may consolidate qualified sources for screw pumps and low-noise units under one roof. That is usually good for engineering support and bad for price leverage, so a multi-vendor strategy for critical hydraulic packages deserves a second look before the deal completes in early 2027.
