Balanced by the bellows, without the need for a stepped shaft. Suitable for working in applications with high pressures. The O-ring resting on the shaft does not cause wear as there is no axial movement. Recommended for working with sticky or viscous fluids that require cleaning progress (CIP) or sterilization processes (SIP) in situ due to the geometry of the spiral-wound bellows.
