Stabilizer-dimmer

Product overview
The IMI Fluid Kinetics Suction Stabiliser is designed to be installed at the pump suction inlet to reduce cavitation, gas entrainment and pressure fluctuations. It provides stable inlet flow, protects pump performance and reduces the risk of damage under sub‑optimal suction conditions. The unit has no moving parts, requires minimal maintenance and is available in carbon or stainless steel with multiple end connection options and pre‑labelled nozzles for simplified installation. Typical applications include power plants, industrial pump stations and other facilities with suction instability.

Key features

• Installed at pump suction inlet to stabilise flow and protect pump performance.
• Reduces cavitation and gas entrainment, extending pump service life and improving reliability.
• No moving parts; minimal maintenance (periodic air charge checks only).
• Pre‑labelled nozzles and multiple end connection options simplify installation.
• ANSI Class 150–2500 pressure ratings; RF flange standard (other flange types available on request).
• Carbon steel or stainless steel body and baffle options.
• Temperature suitability from approximately -50°C to 343°C.
• Pulse attenuation up to 70%; offset horizontal flow design.
• Designed to relevant ASME pressure‑retaining codes.
