Pump and Motor Assembly
Installation
All items included in this section.
The following should be observed for proper installation of the
pump.
1. Pump should be accessible for servicing and inspection.
2. The foundation area should be rigid .
3. The inlet should be as close to the liquid source as practical
and preferably below it.
4. Piping should be supported. Do not use the pump as a pipe
hanger.
5. Install valves to isolate pump during maintenance.
6. Suction and discharge piping should be the same size or
larger than the pump inlet and outlet ports. Install a pressure/
vacuum gage in the suction piping a pressure gage in the
discharge piping.
7. Clean piping as necessary to remove dirt, grit, weld slag,
etc.
8. Provide clearance behind motor to remove motor and outer
magnet (24) approximately 2 feet.
9. For further instructions on mounting or installing your pump,
refer to the Hydraulic Institute Handbook.

Removal from System
When the pump is handling flammable, toxic or hazardous fluid,
flush the pump prior to removal from the piping system. Prior
to flushing and disassembly consult the Material Safety Data
Sheet (MSDS) for the pumped fluid to ensure procedures and
precautions as specified are adhered to. Exercise extreme care
to avoid contact with the fluid.
Insure the pump’s motor switch is in “off” position and locked
out.
Maintenance
Flush the pump and drain. Use drain connection “if option has
been installed”.
!
Maintenance and Repair
The pump has internal bearings that will require replacement
over time.
The selection of a sealless pump may have been due to a
concern for leakage of hazardous liquids. When performing
maintenance on this pump, cautionary steps should be taken
to ensure proper drainage or cleansing of the liquid inside the
pump prior to disassembly.
Work Safety
Magnetic drive pumps contain strong magnets, which pose risk
to people and property. Based on this, the following must be
observed.
1. Individuals with cardiac pacemakers should avoid repairs on
these units.
2. Individuals with internal wound clips, metallic wiring, or other
metallic prosthetic devices should avoid repairs on these
units.
3. Strong magnetic field can cause tools and parts to slam
together; injuring hands and fingers.
4. Keep magnets away from credit cards, computers, computer
discs and watches.
Start-up
Preliminary
BE CERTAIN MOTOR IS LOCKED OUT.
1. Open suction and discharge valves.
2. Check system for leaks.
3. Rotate unit by hand. On close coupled units, rotate motor
fan.
4. Be certain guards are in place.
5. Remove motor lockout.
6. Jog pump to check rotation.
Running
1. Observe suction and discharge gages.
2. Monitor the unit for 15 minutes to make certain it is operating
satisfactorily.
a. Check suction and discharge valves.
b. Check for unusual sound or vibration.
Shutdown
Short Term
1. Stop unit.
2. Lock out motor.
3. Leave suction and discharge valves open.
Long Term
1. Stop unit.
2. Lock out motor.
3. Close and lock out suction and discharge valves.

2. Remove hex bolts (35), and then detach flange support
(23) with discharge flange (2) by lifting straight up as
shown in Figure 2. Remove discharge flange (2) from
flange support (23) and inspect O-ring (3). Replace if
damaged.
1. Remove socket head cap screws (33) using a 5/16” Allen
wrench to detach pump assembly from motor.

Figure 2
Figure 3
3. Position the pump so the suction is facing up as shown in
Figure 3 while being careful not to loose the 3/8” hex nuts
inserted in the bottom rear half of case support (20).
4. Remove hex bolts (28 & 29), and then remove the front
half of case support (20).
5. Insert two flat screw drivers 180° from each other between
case (1) and discharge flange support (22). Using the
screw drivers, gently pry the flange support off the case (1).
Remove suction flange (4) from support. Inspect O-ring (5)
on flange (4), and replace if damaged.
5.1. Remove case (1) from containment can (6). It may be
necessary to remove the case (1) and containment can
(6) from the adapter (26). If the two are removed together,
position them so the containment can (6) is up. Hold
containment can while tapping the case edge around the
case diameter using a small rubber hammer. Do not let case
fall as the two pieces are separated.

10. Remove inner rear wear ring (10) from impeller (7).
Figure 4
Figure 5
Figure 6
6. Remove inner magnet and impeller assembly from pump.
7. If the inner magnet (8) needs to be removed from the impeller,

is available if the stator is stuck or damaged. (Note: the stator
has left hand threads.)
15. Remove containment can (6) from adapter if it has not been
removed. Inspect inside and outside of can and replace if
damaged.
