Alexandria Petroleum Company requested in 2015 to change the design of seal pacing in Asphalt screw pumps GA7010 A/B and GA7011 A/B into mechanical seal.
All mechanical seal Manufacturers faied to get design without modification in this pumps elements. except TISTAM approved this challenge by special design for this application without any modification in pump element such as: Staffing box, Shaft, Bearing housing.
The biggest benefit of using mechanical seals is the drastic reduction in leakage. That reduction in leakage also has an effect on a number of other things as well. Things like a safer work environment without a wet floor, fewer bearing failures caused by leaking fluid, no excessive wear on the shaft sleeve damage from packing.
The maintenance department also sees a savings in time and budget. No more adjusting or replacing packing.
