proSiron double acting cartridge seal

Hydrodynamic balanced seal faces are available in standard materials. Depending on application seal faces are chosen to maximize operating time.

The stationary technology of proSiron offers an increasing of the sliding speed, compared to the dynamical technology of the ecoSiron.

Our proSiron is designed for API sealing concepts with quench and drain ports.
This includes API plans 21, 22, 23, 31, 52, 53A and B as well as 54. For this we offer our supply support systems. As further options, our proSiron are available for ANSI pumps and ANSI+ Big Bore.

In API 23 a better cooling is necessary. Therefore we offer a flow-optimised and medium-contacted conveyor unit as an option.
