Description
RO family seals are mainly designed for sealing crude oil, water and petroleum products in the oil & gas industry. There are several specially engineered seals to cover the needs of the industry:
- Seal for water injection pumps. This seal has special design to protect the dynamic o-ring from hang up and to allow for shaft axial movement of 10 mm to compensate for thrust bearing wear. This new seal has had huge success and is widely used now at TNK-BP’s biggest oil producing division in Russia.
- Special seal for pumps pumping crude oil to main crude oil transportation pumps. This seal also features 10 mm axial movement capability.
- Seal for main crude oil transportation pumps.
- New: 50 – series high pressure mechanical seal. The new seal operates with less friction, less wear and 10 times less leakage compared to older generation seals. Although new, this seal has already proved its high pressure capability at crude oil pumps and boiler feed water pumps.
The RO family seals are used for the same applications as the followings seals:
SH/H7/H75 by Burgmann, Germany
DHTW/QBQ/GSS by Flowserve, USA
8B/RREP/38B by John Crane, USA
Advantages (depending on seal model)
- Ability to compensate for huge shaft travel
- No O-ring hang up
- High pressure capability
