In pumps and rotating equipment, leakage can cause downtime. An o-ring pusher mechanical seal maintains contact between sealing surfaces, helping control leakage and support smooth operation.
Its design combines stable sealing with adaptability. The o-ring supports contact, while the pusher mechanism maintains sealing during movement.
In an industrial pump with recurring leakage, this solution improves reliability. Choosing the right size and material helps solve concerns and keep production!
