SDPM-5200 - Stationary Double Pumping Monolithic Cartridge Seal with Exotic Alloy wetted parts

The SDPM-5500 is a Stationary double cartridge mechanical seal with Exotic Alloy wetted parts, an integral, bi-directional barrier fluid pumping ring and monolithic seal faces. The seal is designed for general high-end applications across all industry sectors, specifically Chemical, Petrochemical and Oil & Gas sectors.

The innovative stationary seal design is offered as a complete cartridge mechanical seal solution and is designed for Plan 53A, 53B and 53C system piping arrangements, but can also be employed for Plan 52 and 54 systems.

Design Features include;

• Large Seal port orifices - 1/2" NPT Barrier Fluid In (BI) and Barrier Fluid Out (BO) orifices for Plan 53 or 52.
• Barrier fluid is directed to the inboard faces via an integral deflector built into the seal gland. As the barrier outlet is over the outboard faces, effective heat removal occurs at both sets of seal faces
• Gland Insert with integral inboard vortex breakers, ideal for applications including slurry or suspended particle/solids in the process media.
• Radial clearances between rotary and stationary components conforming to the best practice requirements of API682.
• Monolithic seal faces for improved high temperature performance
• Stationary seal design with self-aligning stationary seal face. Ideal for high speed applications.
• Multi-spring design with springs out of the process fluid.
• Highly efficient bi-direction barrier fluid pumping ring.
• Used in conjunction with API Plan 53, 53A, 53B or 53C Seal Support Systems.

As standard, the SDPM-5000 is designed to install inside 0.437" (12mm) x-sectional spaces. Designs for smaller x-sectional equipment sizes are available on request.
