FLOATING SEAL
MECHANICAL FACE SEAL
DO-TYPE
The DO type mechanical face seal consists of two identical metal face seals and two rubber O-rings placed on the ramp profile of the metal seal. MOTEK seals comes in two material versions – Alloy cast iron and Alloy Forged Steel grades. The O-ring materials however are of variety of types based on the application requirements.
In cast iron alloys, MOTEK propose two proprietary compositions, selection of which is based on applications requirements.

At Seal assembly the o-rings are compressed between the tapered contact surfaces of the seal ring and housing. The o-rings undergo a calculated compression as per MOTEK standards it is around 25% volumetric compression, which is critical for proper operation of the sealing system also the overall system cleanliness of the o-rings and housing free of oil and dirt is of primary importance. Lubrication of the o-rings with oil or grease is not permitted during the installation process.

Application 1
Trench Cutter
Trench Cutter is an extra-large, high-precision excavation machine used at construction sites to dig deep, narrow guide grooves or to construct diaphragm walls and cutoff walls. It is also widely known by the name hydromill.
Application 2
T.B.M (Tunnel Boring Machine)
T.B.M (Tunnel Boring Machine) is a large piece of mechanical equipment used to bore underground tunnels. This equipment is capable of efficiently excavating soil and rock while simultaneously clearing soil and rock debris. It is primarily used in the construction of various underground structures, such as subways, roads, drainage pipes, and railway tunnels.
