S.C. R O M F L U I D S.A. Systems and sealing elements for hidraulic and pneumatic equipments and instalations

R


Dear customers, Our company produces various sealing systems used in the machine engineering industry, metallurgic industry, iron and steel industry, auto, ship and railing transport industry, mining industry, woodcraft industry, civil engineering, agriculture, food industry, army. The main kinds of sealings produced are: -

sets of “V” shaped fitings made of tissue for rod and plungers at hydraulic cylinders that work in hard exploiting conditions sets of “U” fittings with ring support made of polyamide sets of “T” fittings with ring support made of polyamide scraper fittings “O” rings fittings for pneumatic systems fittings for special appliances -unconventional fluids used at work (emulsions, solutions, glycols, synthetic oils, combustion gases, etc.) - extreme pressures (max. 800 bar)

Materials used – NRB, FKM, VMQ, EPDM, CR, NR, HNBR, PA 6, PTFE, tissue This catalogue presents a summary of the profiles realized, but upon demand we can produce other sealing systems as well. We are at your disposal with information, technical data and catalogue sheets for the sealings that you need.

1. “O” rings for machines, motors, apparata, transmission equipment, hydraulic cylinders and for general use at ISO standard sizes. Upon demand any size may be produced in the range of 1.78 up to 530 mm. Materials used: NBR, FKM, VMQ, HNBR, CR, NR, EPDM, ACM

2. “U” sleeves with and without ring against extrusion made of polyamide used at lead cylinders at machine tools, engineering machines, agricultural machines, presses, pumps, mobile equipment, etc. Materials: NBR, FKM, VMQ.

3 R


3. “T” sleeves with double action, with rings against extrusion made of polyamide, used at the cylinders that work in heavy conditions (earthwork, aircraft industry, etc.)

4. Scraper rings made of high hardness materials (85-90° Sh A) which are used at all the hydraulic cyliders with rod
