Foreword
This manual contains instructions and guidelines for the assembly of the Wilfley SolidLock®static seal cartridge.
There are many factors affecting the successful assembly of a seal cartridge, which makes it impossible to create
a manual that covers all situations. Therefore, the information contained herein is meant to serve only as a
general guideline. If detailed questions or problems arise, contact Wilfley or your authorized Wilfley
representative.
Supplemental manuals may be required depending on the configuration of the pump.
It is extremely important that this entire manual be read prior to installation or start-up of the pump.
Use of the equipment on a service other than what was outlined at the time of purchase could void the warranty,
unless Wilfley has been consulted and provided written approval in advance.
To assure proper installation, supervision from an authorized Wilfley representative is recommended.
A.R. Wilfley and Sons, Inc. shall not be liable for damage or delays caused by a failure to observe the instructions
that are contained in this manual.
Warranty is only valid when genuine Wilfley parts are used. Contact your authorized Wilfley representative for
basic warranty information and before making any changes.

3.0 Pump Assembly
1. Assemble pump according to the pump IOM manual until the step to install the seal assembly is reached.
2. Install rotary seal subassembly onto the pump shaft so that the rotary seal (S2A) is facing away from the
power end of the pump. Do not tighten the four set screws (S2P) on the subassembly.
3. Install stationary seal subassembly onto the pump so that the stationary seal (S1D) is facing towards the
power end of the pump.
4. Complete final assembly of the pump according to the pump IOM manual.
5. Set the impeller clearances according to the pump IOM manual.
6. Proceed to next section to set the seal clearances.
*Stationary seal subassembly varies with pump model (Kpro®shown above)

4.0 SolidLock®Seal Adjustment
The seal MUST be adjusted and locked AFTER the pump has been assembled AND the impeller clearance has
been set according to pump IOM. Before you begin, ensure that the set screws (S2P) are loose and that the
rotary seal subassembly can freely move axially along the shaft sleeve.
1. Firmly push the rotary seal subassembly against the stationary subassembly until the seal faces come into
contact.
2. Evenly tighten the four set screws (S2P) to lock the position of the rotary seal subassembly.
3. Pull the two pins (S2H) out of the rotary seal subassembly. It may be necessary to pull on the weights (S2E)
to be able to pull the pins (S2H).
**The pump is now ready for use**
When resetting pump clearances, performing maintenance, or disassembling the pump, the rotary seal
subassembly must be reset with the pull pins (S2H). First ensure that the pump casing is void of fluid and
pressure. Pulling up on the weight (S2E) nearest the hole with the pin (S2H) will help line up the two radial holes.
Once both pins (S2H) are in, the set screws (S2P) may be loosened and the rotary seal subassembly may be
adjusted or disassembled from the pump.
