 Structural featrures:
This is a stationary, balanced, multi-spring and single end face mechanical seal.
It’s applicable for working conditions of high-speed shaft seals and widely applied for shaft seals of boiler water feed pumps of 100,1000-300,000 thermal power generator units and large-scale high-speed centrifugal pumps in petroleum and chemical engineering.
Application scope:
Pressure: 0.2~2MPa
Shaft diameter: ф50~ф200mm
Temperature: normal temperature~170℃
Linear speed: ≤50m/s
Application: clear water, oil and other slightly corrosive liquids.
