1 Cartridge Installation Instructions
The following instruction manual is designed to simplify the installation of a typical
SLM-6000 or SLM-6100 slurry seal. The SLM-6000 is a single seal with no quench port
connections, the SLM-6000 QCD adds an elastomer type quench containment device
(V-ring or lip seal) and 2 quench port connections to the single seal and the SLM-6100
adds a basic end face quench containment mechanical seal to make a tandem design
with a circulating device and 2 quench port connections to the single seal.
By reading this manual and following its guidelines, seal performance can be improved
by eliminating the chances of premature failure due to improper installation. In addition to
these instructions, consult the seal assembly drawing included for your specic seal design,
materials of construction, critical dimensions, and any auxiliary piping connections.
As you go through this manual you will nd some of the instructions referenced with gure
numbers. These illustrations are provided to help you visualize what the instruction is trying
to explain. If these instructions are followed faithfully, the seal installation will be successful,
and maintenance personnel will understand the proper procedures to follow when pump
adjustment is necessary.
For special problems encountered during installation, contact your nearest Flowserve Sales
and Service Representative or Authorized Distributor.

2 Recommendations
To ensure that your SLM-6000 Mechanical Seal will provide you with the longest possible
life, we recommend the following:
2.1 New radial and thrust bearings be installed in the pump.
The images of parts shown in these instructions may differ visually from the actual
2
parts due to manufacturing processes that do not affect the part function or quality.
2.2 The saddle ts of the bearing assembly should not be worn.
2.3 The axial end oat of the pump shaft must not exceed 0.25 mm (0.010"). See Figure 2.
Check Axial Shaft Travel Figure 2
0.25 mm (0.010") Maximum
Acceptable Axial Movement
2.4 Shaft radial runout should be less than 0.0005 mm per mm (0.0005" per inch) of
shaft/sleeve diameter. See Figure 3. Turn the shaft through 360° and observe the
range of indicator movement.

Run Out 0.0005 mm per mm
(0.0005" per inch) of shaft

2.5 The shaft should deect no more than 0.30 mm (0.012") at the seal chamber face.
See Figure 4.

2.6 Ensure that the shaft or shaft sleeve has a 1.6 mm (0.06") x 30° chamfer on the
leading edge to prevent O-ring damage at seal installation.
2.7 Hardened shaft sleeves must not be used when cartridge sleeve locking is
accomplished by set screws bearing directly into the shaft sleeve. Any of the sleeve
collars that clamp the cartridge sleeve to the shaft sleeve may be used on hardened
shaft sleeves.
3 General Instructions
3.1 Ensure that the bearing assembly is mounted correctly (central and square) to the
pump pedestal and securely fastened.
3.2 Ensure that all t locations on the pedestal are clean and free of burrs.
3.3 Clean the pump shaft/sleeve surface, making sure it is clean of product and rust
and has no burrs.
3.4 If the pump design requires it, bolt seal adapter plate to equipment case/pedestal
(hand tighten only).
3.5 Locate the seal t of the adapter to the shaft by use of a dial indicator or centering jig.
The equipment shaft must be concentric to the seal adapter bore to within 0.38 mm
(0.015"). See Figure 5.

3.6 For adapters provided with a centering jig, simply insert the centering jig into the
adapter and tighten adapter bolts alternately, adjusting the cover location until the
centering jig can be removed by hand without binding.
3.7 Apply a light coat of O-ring lubricant to the seal sleeve O-ring. (Silicone grease must
be used with EPDM gaskets.)
Warning: Do not apply anti-seize or other lubrication to the pump shaft/sleeve. Keep
the shaft/sleeve clean and dry. The use of lubricants will cause improper clamping
pressure by the clamp collar.
