Mechanical Seal Design & Repair For The Refrigeration & Cold Storage Industry

This Mycom 160 double seal set was sent in from a plant in San Antonio, Texas. The rotary double seal assembly had been slipping on the rotary shaft because the setscrews backed off. The I.D. bore of the rotary seal housing was scored up and the o’rings were burnt up. The two stationary Carbon seats were chipped out and needed replacing. We machined two new stationary Carbon seats in house and relapped the two rotary Tungsten Carbide seal faces. Rotary seal housing was re-machined and polished in I.D. o’ring grooves to remove wear. New springs installed with new Viton o’rings. Seal was repaired under emergency basis 24 hr. turnaround.

Howden 255 MK IV seal set sent in from Illinois. This seal had extensive wear on both the rotary Carbon seal face and stationary steel seat. We machined a new Carbon seal face in house and re-machined the steel seat. Both faces relapped flat within 2 Helium light bands. Repair carried out within 24 hrs.
