Collection of FRICK and MYCOM INDUSTRIAL REFRIGERATION COMPRESSOR SEALS repaired by Robco of America. Protective WAX applied to the LAPPED seal faces & seats.
These are two CUSTOM DESIGNED assembly seals for a HORIZONTAL MIXER. The mixer handles Rubber compounds with Toluene, MEK, DMF, Ethyl Acetate & Ethyl Alcohol additives.
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.
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.
These are 3.50″ Robco EV05 custom designed cartridge seals for a splitcase pump in a water district pumping station.
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.
This is a set of (24) nozzles comprising of a tapered Silicon Carbide insert that engages into a Hastalloy “C” housing with a tapered I.D. bore. These nozzles are installed in a 12,000 rpm centrifuge application in a chemical plant in Arkansas.
