Alignment Procedure for MSS Pumps
STEP 1: General PreparationIf pump and motor are mounted on a skid,•Skid must be leveled and shimmed to support:
•Weight of motor and pump.•Weight of membrane housings, process piping, and all other equipment
installed on the skid when filled with water.
If pump and motor are mounted on concrete foundation,•Foundation must be leveled.• Anchor bolts must be properly installed and tightened.
Skid Shim
Foundation
Anchor bolt
NOTE: If your pump has a rotated inlet, rotate the inlet to the verticalposition prior to alignment. Once alignment is complete, rotate the inletback to it required location.

STEP 2: Level the Motor
1. Pump end and motor should not becoupled at this time.
2. Verify motor feet sit flat on mountingsurface (no “ soft foot” ).3. Place level on motor shaft.4. Adjust motor shims until
motor shaft is level.
3. Tighten motor foot bolts to mountingsurface.4. Verify shaft remains level.
NOTE: Motor must be placed at final installation location prior tostarting alignment procedure

STEP 3: Prepare for Alignment1. Install the two (2) alignment pins2. Discharge cradle halves should not
be bolted together at this t ime.
3. Pump end should rest on the bottomhalf of the discharge cradle to allowthe pump to slide axially duringalignment.
4. Sl ide pump onto motor face.• Coupling NOT installed• Ensure motor adapter is fully
engaged with motor face5. Place level across inlet .6. Adjust bottom half of pump leveling
foot discharge cradle until levelusing adjusting nuts.
7. Do NOT tighten down top half ofdischarge cradle at this time.

STEP 4: Ensure Mounting Flanges are Parallel
1. Check for uniform gap between motoradapter and motor face throughout theentire interface.• If there is no gap, or gap is
uniform, proceed to Step 5.•
If gap is not uniform, proceed to #2below.
2. Using feeler gauge, measure clearanceon one side of gap.
3. Measure clearance on other side.4. Move pump discharge end sidewise
until clearance is uniform.
Make clearanceuniform
Feeler gauge

STEP 5: Check Shaft Gap
1. Install two motor adapter bolts to drawpump to motor.
2. Measure gap between motor andpump shafts.• Gap should be between 1/8” (3
mm) and 1/4” (6 mm).
Shaft gap between 1/8 and 1/4inches (3 to 6 mm)

STEP 6: Lubricate Shafts
1. Remove the two bolts installed inprevious step.2. Separate pump and motor.3. Liberally apply anti-seize to pump and
motor shafts and coupling bores.•
Use anti-seize provided in smallpouch.
Apply anti-seize to these areas

STEP 7: Install Coupling
1. Instal l key on motor shaft.2. Sl ide coupling on motor shaft.
• Push until firmly seated.3. Install both set screws and firmly
tighten.• Note that there are NO set screws onthe pump side of the coupling.
Tighten both set screws

STEP 10: Final Installation – Motor Adapter
1. Install two (2) motor adapter boltsand tighten *.
2. Remove two (2) alignment pins.
3. Install remaining adapter bolts andtighten *.
Install and tighten all motoradapter bolts
*For 1/2” bolts, tighten to 30 ft-lbs*For 5/8” bolts, tighten to 60 ft-lbs

STEP 11: Final Installation – Leveling Foot
1. Place level on inlet .2. Bring top half of discharge cradle
down to meet bottom half.3. Begin to tighten down top half ofdischarge cradle.
4. During tightening, the cradle maydraw the pump downward.
5. Verify that pump remains levelduring tightening.• If pump comes out of level, raise
the bottom half of the cradle untilpump is again level.
•
Repeat this process until cradleis fully secured and pumpremains level.
6. Tighten down cradle jamb nuts.

STEP 14: Piping Alignment CheckPump and pipe
connections are aligned
Proper gap
A good pump-motor alignment can beruined by improper alignment of thepiping.
Please make sure that suction anddischarge piping are concentric with thepump connections and have the propergap prior to installation of the Victauliccouplings.
DO NOT FORCE THE CONNECTINGPIPES INTO POSITION!
