Non-Metallic Centrifugal Pumps

Installation and

Maintenance Instructions

ASSEMBLY

Unpack pump from carton and check for shipping damage.

WARNING: Magnetic field hazard. This pump contains powerful rare

earth magnets. When the pump is disassembled (not connected to a motor)

and the magnets are exposed, these magnets produce powerful magnetic fields.

Individuals with cardiac pacemakers, implanted defibrillators, other electronic

medical devices, metallic prosthetic heart valves, internal wound clips (from

surgery), metallic prosthetic device or sickle cell anemia must not handle or be

in the proximity of the magnets contained inside the pump. Consult a health

care provider for specific recommendations before working with this pump.

ATEX COMPLIANT PUMPS

All assembly, installation, and maintenance instructions are the same as

standard pumps with the exceptions noted on page 3 under "Safety Precautions

for ATEX pumps."

PUMPS WITH MOTORS

Remove shipping plugs and insert from suction and discharge and proceed to

installation instructions.

PUMPS WITHOUT MOTORS

1. Remove wet end assembly from box.

CAUTION: Strong magnets present. Keep metal objects and

metallic chips/particles away from pump components.

2. Remove hardware package from box.

3. Install motor adapter (item 6) onto motor with labels at top

using items 10 and 11.

4. Remove drive mag assembly (item 5) from box and slide

assembly onto motor shaft making sure shaft key (item 12)

is in place. Installation dimension is .060 +/‑.010 inches as

shown in Figure 1. Tighten 2 set screws (item 5A) to 228

in‑lbs. (25.8 N‑m).

5. Gripping the discharge and the side of the impeller hous‑

ing (note above warning), carefully install the wet end into

the motor adapter. Note that the two housing studs (item

15) should be located at 3 and 9 o'clock (for 12 o'clock

discharge location) and will go through the motor adapter.

6. Install the 5/16 x 3/4 SS hex bolts (item 7), the 5/16 ﬂat

washers (item 9), and the 5/16 hex nuts (item 8) and

tighten to 70 in‑lbs. of torque using the pattern shown in

ﬁgure 2.

7. Remove the two‑piece shipping plug from the suction.

8. Reach into the suction and spin the impeller to check if it

spins freely. If it does not, disassemble and recheck the

drive hub installation instructions in step 4.

9. Install pump into the system according to the following

installation instructions.

IMPORTANT: Verify the tightness of the set screws in the

drive magnet assembly prior to operation.

WARNING: Components can slam together from strong

magnets. Keep ﬁngers away from area between housing

and motor adapter.

INSTALLATION

MOUNTING

Motor or base plate should be securely fastened.

PIPlNG

1. Support piping near the pump to minimize strain on pump

casing.

2. To minimize head loss due to friction:

a. Increase pipe size 1 diameter

b. Use minimal number of bends

3. Keep pipe bends a minimum of 10 pipe diameters from

suction and discharge. For example, if using 2" pipe, ﬁrst

bend should be at least 20" from suction discharge.

4. Position pump as close to liquid source as possible.

5. Maintain a ﬂooded suction.

6. Ensure that piping is leak proof.

7. Install valves on suction and discharge lines (minimum of

10 pipe diameters from pump).

8. For units in suction lift system, install appropriate piping in

discharge to allow priming of pump.

3. 4. 9. The suction valve should be fully open to avoid restricting suction flow. IMPORTANT: To protect the pump if prime is lost, use one of the following: (1 ) pressure switch on the discharge; (2) vacuum switch on the suction; (3) a power monitor to monitor motor current. 10. When pumping liquids which may solidify or crystallize, a flush system should be added to the piping. See Figure 3. Install water inlet and outlet valves as shown. MAINTENANCE DISASSEMBLY 1. 2. 3.

SAFETY PRECAUTIONS FOR ATEX PUMPS Note: On closed impellers, use two screwdrivers in slots provided to pry apart impeller and impeller drive. CAUTION: Proper o-ring material must be chosen for the fluid being pumped. Improper material selection could lead to swelling and be a possible source of leaks. This is the responsibility of the end user. BUSHING AND THRUST RING REPLACEMENT 1. To remove the bushing, place the impeller assembly (items 2 and 3) in an arbor press.
