NOTe: To facilitate assembly, place the pump casing so that
it is standing on one of its flanges with a block of wood under
the mounting flange. See FIGURE 5.
1. Install the casing bushing. See “iNSTaLLaTiON Of
CarbON graPhiTe buShiNgS” on page 6.
2. See figure 8, and notes under “MeChaNiCaL
SeaL” on page 6. Install the stationary member of the
mechanical seal into the mechanical seal plate. Coat the
mechanical seal plate o-ring with oil or grease to keep it
in place and in-stall the mechanical seal holder plate into
the shaft end of the casing.
3. Apply a coating of light oil onto the shaft in the seal area,
then install the rotating member of the mechanical seal
onto the rotor/shaft assembly.
4. Slide the rotor/shaft assembly into the casing, taking
care not to damage the bushing or the seal faces.
NOTe: When installing a new rotor/shaft assembly, use a file
to carefully remove all burrs and sharp edges.
5. Coat the head o-ring with oil or grease and slip it over
the head pilot to keep it in place. Apply a coating of light
oil onto the bushing ID and the crescent. Place the idler/
bushing assembly onto the idler pin.
NOTe: When installing a new head/pin assembly, use a file
to carefully remove all burrs and sharp edges, especially
around the loading groove.
6. Install the head. For proper head positioning, the pin
should be at the top centered between the two ports. If
the pump is equipped with a jacketed head plate, install
at this time. Tighten cap-screws evenly.
Refer to
figure 4 and figure 5 for bearing housing
assembly.
7. Install the closure in the bearing housing (See the
appropriate figure for lip orientation).
8. Ke and KKe PuMPS: Pack the ball bearing with grease
and push or press the bearing into the bearing housing.
See figure 3 on page 2.
LQe PuMPS: Pack tapered roller bearings with grease
and press or push bearings into housing with large end
of inner races together. It is possible to install bearings
incorrectly. For proper assembly (See figure 5 on
page 3).
9. Install the closure in the end cap (See the appropriate
figure for lip orientation). Thread the end cap into the
bearing housing along with outer bearing spacer collar
and tighten against the bearing.
LQe PuMPS ONLy: Tapered roller bearings re-quire
preload to operate properly. To set preload tighten end
cap so that inner races of bearings cannot be rotated by
hand. Back the end cap off to allow inner races to rotate
with slight resistance.
Lock end cap in place with two set screws in the flange
of the bearing housing.
10. Slide inner spacer collar over shaft with recessed end
facing rotor.
Place pair of half round rings on shaft and slide inner
bearing spacer collar over half round rings to lock them
in place.

11. Thread the bearing housing with closures, end cap,
outer bearing spacer collar and bearings in-stalled into
bracket. Make sure inner spacer collar keeps split rings
locked in place.
12. Insert a length of hardwood or brass through the port
opening between the rotor teeth to keep the shaft from
turning. Put the lock washer and lock-nut on the shaft
and tighten 100 - 200 N•m and bend one tang of the lock
washer into a slot of the locknut.
13. Adjust the pump end clearance as instructed in “ThruST
beariNg aDJuSTMeNT” on page 6.
14. Lubricate all grease fittings with multi-purpose grease,
NLGI #2.

DaNger !
before starting the pump, be sure all drive
equipment guards are in place.
failure to properly mount guards may
result in serious injury or death.
For disassembly, see “DiSaSSeMbLy” on page 4.
For assembly, see “aSSeMbLy”.
NOTe: Never touch the mechanical seal faces with anything
except clean hands or a clean cloth. Minute particles can
scratch the seal faces and cause leakage.
Always clean the rotor and shaft and seal housing bore
before installing the mechanical seal. Make sure surfaces
are clean and free of scratches.
There are two available mechanical seals. The standard,
shown in figure 8 on page 7, is for applications pumping
liquids with viscosities up to 3,500 SSU. There is also a “pin
style” seal available with the stationary face pinned to the
seal plate for applications pumping liquids with viscosities up
to 10,000 SSU.
