Single helical spring mechanical seal
Hydro Serve Technologies

H15/H16 Are single coil spring unbalanced seals, these seals are simple in design & reliable & rugged enough for the most difficult applications.
Designated as H15 & H16 for 'O' Rings & 'V' Packing used as Secondary seals respectively.
Special notches enhance the required driving torque & hence the seal is independent of direction of rotation. Non-clogging spring design enables these seals to be reliably used in situations involving abrasive, corrosive & viscous fluids generally handled by high Temperature pumps.

Applications :
Generally used in refineries, fertilizers, nuclear plants & petroleum pipelines.
