KC11 Series - Self Priming Option

Installation and Maintenance Instructions

INTRODUCTION

FTI’s MagPrime Chamber provides a self-priming feature
to the KC1145 sealless centrifugal pump. A state-of-the­art, one piece modular design allows the MagPrime pump
to lift liquids up to 15 feet (4.57 meters) in two minutes.

HOW IT WORKS

The MagPrime Chamber is initially filled with liquid. When
the pump is started, recirculating liquid creates a vacuum
in the suction line. This vacuum draws air from the suc­tion line and releases it through the discharge outlet.
When the liquid in the suction line reaches the pump in­let, the pump is primed and normal operation begins (see
Figure 1).

SAFETY PRECAUTIONS

WARNING: Read this instruction manual com-pletely
before installing and operating this unit. Fail-ure to follow
these precautions can result in serious bodily injury.

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 pacemakes, implanted defibrillators, other
electronic medical devices, metallic prosthetic heart valves,
internal wound clips (from surgery), metalic prosthetic
devices or sickle cell anemia must not handle or be int he
proximity of the magnets contained

• Wear proper eye and skin protection when installing,

operating, and maintaining this equipment.

• All electrical wiring (e.g., motor) should be performed

by a qualified electrician.

• Never use this pump for flammables or combustibles.

• Verify chemical compatibility of the pump’s materials

of construction with the liquid being pumped.

o

• Maximum liquid temperature is 120

F (49oC).

INSTALLATION

The MagPrime Chamber comes complete with housing
gasket and hardware. The user must supply 1-1/2” rigid
suction piping and 1-1/4” discharge piping. The suction
inlet is located at the front of the priming chamber.

SECTION 1 - INSTALLATION OF MAGPRIME
CHAMBER FOR AN EXISTING KC11 PUMP

1. Remove any piping from the pump impeller housing.

2. Remove the (5) 1/4- 20 x 1” bolts and (4) Phillips pan
head screws from the impeller housing.

3. Gently tap the impeller housing’s discharge outlet
(using rubber mallet) to remove the impeller housing.

4. Save the impeller housing - DO NOT DISCARD. It is
necessary for pump assembly and disassembly.

5. Remove the old housing o-ring (item 7) from the pump
barrier (item 8) and discard.

6. Install the new housing o-ring (supplied with Mag­Prime Chamber) onto the pump barrier.

7. Verify that the white ceramic thrust washer is firmly
seated into the MagPrime Chamber.

8. Install the MagPrime Chamber by aligning the groove
in the MagPrime Chamber with the ridges on the
KC11 barrier. Press in place until firmly seated.

9. Install the (5) 1/4-20 x 1-3/4” hex bolts, washers and
nuts (supplied with the MagPrime Chamber). The
nuts will insert into the back tabs on the motor adapter
(item 13). Tighten each bolt to between 30 and 35
in.-lbs. (3.4 and 4.0 Nm) using star pattern sequence
(shown in Figure 2 of the KC11 Series Installation
and Maintenance Instructions). Do not overtighten.

NOTE: Periodic retightening of the bolts is required.
The bolts will loosen from vibration and the expan­sion/contraction of the plastic parts.

10. Firmly support the motor, prime chamber and piping.
Shim as necessary. Important: Failure to support
these items will result in damage to the pump.
