- 2 mechanical seal configurations
John Crane Type 5840 Slurry Seal
The 5840 seal is an outboard cartridge seal for ABB Baldor submersible motors only. It is used in conjunction with a single John Crane Type 21 internal seal (carbon/ceramic faces) in the motor oil chamber. This provides for a tandem seal arrangement with two independent seal systems. This is the most robust seal design offered with higher pressure and radial runout allowances with minimal exposed parts.
- 2205 duplex stainless construction standard (2507 super duplex and C276 optional)
- Silicon carbide seal faces
- Encapsulated spring
- Primary ring secured by set screws
- Secondary ring secured by anti-rotation pin
- O-ring fits
- Can be used on motors for UL Listed Cl. I Div. I Groups C & D locations
- Seal can often be repaired vs. replaced for lower maintenance cost

Internal Double Slurry Seal
Both EIM and ABB Baldor motors can use this seal configuration. It is a back-to-back double seal configuration where two sets of faces share a single spring. The entire assembly operates in the motor oil chamber and does not see the process fluid. This seal is also protected by a lip seal as the first barrier of protection. This seal is great for less severe applications and is more cost effective than the 5840.
- EIM motors use Eagle Burgmann ED560 with silicon carbide lower (process) faces and carbon ceramic upper faces
- EIM motors carry FM Approval for Cl. I Div. I Groups C & D hazardous locations
- ABB Baldor motors use a John Crane Type 21 double seal with tungsten carbide lower faces and carbon ceramic upper faces
- Stainless steel (316 and 304 construction) with fluoroelastomer bellows
- O-ring fits for stationary faces
- Lower stationary face is further secured via anti-rotation pin
