SAPI-3131 - Exotic Alloy Single cartridge stationary seal with integral vortex breakers for Plan 31
The SAPI-3131 is a single exotic alloy cartridge mechanical seal with innovate integral vortex breakers in the gland plate. The seal is well suit for a wide range of abrasive process pump applications given it can be supplied in hard wearing wetted materials such as Duplex, Super Duplex, C22, C276 and C255 making it ideal for pumps in the minerals extraction sector or to API 610 Ed.6 to Ed.8 pumps in the oil and gas sector.
The innovative stationary seal design is offered as a complete cartridge mechanical seal solution and is designed for API Plan31 arrangements.
Design Features include;
- Exotic Alloy Wetted parts for optimum abrasion and/or corrosion resistance.
- Bi-directional Flush orifice for Plan 31 systems. Important: The flush orifice does not 'shot blast' the stationary seal face when used with process liquids containing suspended particles.
- Large Seal port orifices - Flush 3/8" NPT
- Gland plate with integral vortex breakers
- 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.
- Can be used in conjunction with the Stanseals Plan 31 Cyclone Separator system and Sample collection pot.
The SAPI-3131 is an innovative exotic alloy stationary seal, designed for a wide range of Plan 31 applications.
The seal also incorporates best practice features, as detailed in our technical blogs and white papers.
Safe Operating Limits:
This seal incorporates best practice features and innovation as detailed in our technical blogs and white papers.
** Apply "industry standard" Pressure, Speed and Temperature de-rating factors, by shaft size and application. The safe seal performance characteristics are typical characteristics for each variable in isolation. The individual upper limit values of each variable should NOT be used in multiple combinations of Speed, Pressure and Temperature. Contact our Technical Sales Department for further details.
