APIC-8053-23 - Double Cartridge Stationary Plan 53 and 23 Seal with Full Graphite and integral R- Bush for API610 & API682 Pumps

The APIC-8053-23 is a multi-spring high temperature double Plan 53 and Plan 23 stationary cartridge seal with hydraulic balanced seal faces. The innovative design has springs out of the process media, therefore excellent for viscous or corrosive process applications.

The seal design comes with integral inboard restriction bush which helps to isolate the process media in the seal chamber, reducing the "work rate requirement" of the plan 23 system and system cooling. This innovative seal design has stainless steel wetted parts and is offered with a highly efficient bi-directional pumping ring for both Plan 23 and Plan 53. The pumping ring conforms and exceeds the requirements of the API682 standard for pumping ring radial clearances.

The APIC-8053-23 stationary pusher double cartridge seal has Monolithic seal faces which are ideal for high temperature sealing and full graphite secondary seals for the ultimate high temperature resistance. The design incorporates secondary sealing elastomers (including scarifical elastomers) which can be supplied in a range of materials to suit the application.

The mechanical seal comes with Multi-Springs, Set Screw Drive and 1/2" NPT Plan 23 FI (IN) and Plan 23 FO (OUT) port connections, as well as Barrier in (BI) and Barrier Out (BO).

Importantly, the seal has BOTH directed plan 23 and plan 53 flow paths, ensuring cool fluid is delivered to the seal faces for optimum seal face longevity.

The seal also has an outboard 'floating' restriction bush, as well as Vent (V) and Drain (D) connections which can be employed for Plan 62 quench to drain systems, or seal leakage monitoring. The seal comes factory assembled and tested.

This is an ultimate reliability-focused mechanical seal solution, which can fit old, API 610 process pumps as well as modern API 682 designs.
