These two VIKING PUMPS (KK4125) were sent into our Houston repair facility for overhaul from an ADHESIVES MANUFACTURER in Texas. The mechanical seals were upgraded to handle the ELEVATED OPERATING TEMPS. Both pumps were overhauled and pressure tested to 80 PSIG for 15 min. with no pressure drop.
Robco of America DESIGNED & had these SILICON CARBIDE WEARPLATES manufactured to be installed into HIGH RPM CENTRIFUGAL ATOMIZER units. The wear plates are SHRINK FITTED into outer HASTALLOY C276 rings.

This is a 100mm Pillar double cartridge seal. We installed new Silicon Carbide & Tungsten Carbide faces and machined a new outer end Carbon Graphite seal face. Chrome Oxide coated seat was relapped flat.
A chemical plant in East Texas sent two Chemineer agitator seal units in to our Houston, Texas facility for repair. The seals were in extremely poor condition with a lot of corrosion and wear. Both seals required new seal sleeves and double walled cooling jackets machined. Product side rotary seal faces were upgraded from Carbon to Tungsten Carbide to handle the abrasive elements in the mixed product.
The two stationary seats in each unit had been "slipping" in their housings causing wear on the o'ring sealing surfaces. This was due to the OEM seals not having anti-rotation pins installed to stop this from happening. We modified the stationary seat housings to stop this from being a future issue. These two seal units were repaired in 5 working days due to customer losing production.
