Product Description
TECHNICAL FEATURES
•Primarily utilized to suit the requirements of the Oil and gas industry application defined by API682.
•Both inner and outer seals adopt a design combining flexible graphite and metal bellows, which maximally ensures reliability under high-temperature operating conditions.
•Under high-temperature operating conditions, the special pump efficiency ring design can maximize the dissipation of heat generated by the front-end medium.
•The stationary ring adopts structural position limiting.
Pumping screw for media with higher viscosity also available
•The outer sealing, combined with the Plan 52, provides additional suppression sealing effect, while the Plan 53A/53B/54 maximizes the suppression of high-risk fluid leakage into the atmosphere.
•Well perform under Arrangement 2 or Arrangement 3 operation, containment control or eliminate of process emissions.
•Rugged design for long opera ng life.
