Series 60
Single Coil Mechanical Seal
Type: 60U and 65U
Series 60U and 65U are single coil spring unbalance seal with O-Ring as secondary sealing member in series 60U and V packing as a sealing member in 65U. Various face material & elastomers can be offer for wide service application. The compact design of seal permits their use in all types of centrifugal pump. Non-clogging spring design enables these seals to be reliably used in situations involving abrasive, corrosive & viscous fluids generally handled by high Temperature pumps.
Type 60U
Secondary Seal Material: Viton / Buna / EPDM or Neoprene ‘O’ Ring in order to ensures less shaft fretting due to capacity for flex and roll. ‘O’ Ring Seals are preferred where elastomer are suitable for process fluid.
Type 65U
Secondary Seal Material: PTFE V Packing ensures the seal usage in mostly all chemical applications.
Applications
- For Slurry / high viscous liquid/ abrasive services from low to medium pressure & temperature range. It is suitable for various industries such as General Chemicals, Petrochemicals, Light Hydrocarbons, Refineries and Fertilizers etc.
