Hydac Suction Flow Stabilisers SB...S
Suction flow stabilisers SB...S
- V = 12 ... 400 l
- pmax = 40 bar
The HYDAC Suction Flow Stabiliser ensures smooth pump operation by improving NPSH, preventing cavitation, and reducing pipe oscillations. Designed for piston and diaphragm pumps in utilities, chemical processing, and reactor systems, it uses a baffled, welded steel or stainless-steel vessel with an internal bladder to dampen pulsations and separate air. Installed vertically near the pump inlet, it enhances reliability and protects against costly system damage.

- V = 12 ... 400 l
- pmax = 40 bar
The HYDAC suction flow stabiliser:
- improves the NPSH value of the system,
- prevents cavitation of the pump
- prevents pipe oscillations
Applications:
Main application areas are piston and diaphragm pumps in public utility plants, reactor construction and the chemical industry
General Function:
Trouble-free pump operation is only possible if no cavitation occurs in the pump suction and pipe oscillations are prevented.
A relatively high fluid volume in the suction flow stabiliser in relation to the displacement volume of the pump reduces the acceleration effects of the fluid column in the suction line. Also an air separation is achieved due to the extremely low flow rate in the suction flow stabiliser and the deflection on a baffle. By adjusting the charging pressure of the bladder to the operating conditions, the best possible pulsation damping is achieved
Design:
The HYDAC suction flow stabiliser consists of a welded vessel in steel or stainless steel. Inlet and outlet are on opposite sides and are separated by a baffle. The upper part houses the encapsulated bladder. In addition, there is a vent screw in the cover plate and a drainage facility on the bottom
Installation:
As close as possible to the suction inlet of the pump. Mounting position vertical (gas valve uppermost)
