Is one of your pumps a candidate for upgrade from
packing to new split seal technology?
Pumping Solutions® can install this seal in our shop in conjunction with a pump repair or in the field by one of our service technicians. 


Split Seals

Patented cartridge 2-piece design

Smart SealsSM, a division of Pumping Solutions®, is a full-service authorized distributor of Flex-A-Seal®. We are proud to have them as part of our seal division.
Fast, Simple and Reliable
Split Seals are designed for environments where it normally takes many hours of rotary equipment disassembly to access a standard mechanical seal. However, many conventional split seals require gluing o-rings, special tools, and multiple assembly steps for complete installation and assembly. But the patented, Flex-A-Seal Style 85 fully split cartridge seal design is much easier to install than other split seals. The Style 85 is the only split seal in the world in which just two pieces are handled. Simply attach the two pre-assembled halves over the shaft and mount to the pump like any other cartridge seal. This means no shims, no special tools, and no glue required for installation. The Style 85 is also the only split seal that can be fully assembled and pressure tested at the factory.

This makes the Style 85 split seal ideal for hard to access equipment and large rotating equipment such as:
  • Split case pumps
  • Large centrifugal pumps
  • Mixers
  • Agitators

The Style 85 is commonly used in many industries:
  • Chemical Processing
  • Food Processing
  • Industrial
  • Mining
  • Pharmaceutical
  • Power Generation
  • Petrochemical
  • Pulp and Paper
  • Refining
  • Water and Waste Treatment

Split seals in the field

Application: Severly worn obsolete split case pump.

Upon inspection: Pump required complete rotating element repair: Weld repair of worn bronze impellor, new case rings, shaft and sleeves. Field machine the corrosion on face of seal chamber to accept upgrade to patented Flex-A-Seal® split cartridge seals.

Results: Pump running at peak performance with zero seal leakage.
