⚠
CAUTION
It is important that the entire contents of this booklet
be studied before installation.
All parts of the pump below the mounting plate are
constructed of corrosion resistant non-metallic
materials except the pump shaft. The shaft is stainless
steel encased in a CPVC sleeve. The major parts are
made from CPVC. These parts have been carefully
designed to safely handle all operating loads
anticipated. They should still be treated with care, to
avoid damage to the pump. All piping must be
independently supported and all temporary external
loads on the pump must be avoided. Be careful not to
over-tighten the fasteners used on the pump. Please
pay strict attention to the maximum torque values listed
below for the various fasteners.
Auxiliary connections
Do not install metal pipe fittings directly onto pipe
connections on non-metallic parts. These items are
polypropylene and included with pump.
Pump bolting: All plastic bolting below mounting
plate not to exceed 10 foot-pounds torque. All metal
bolting at underside of mounting plate not to exceed 20
foot-pounds torque.
SAFETY
This manual contains instructions for installation,
operation and maintenance of your Series 'EFB'
centrifugal pump. It has been designed to provide safe
and reliable service. However, it is both a pressure
vessel and a piece of rotating machinery. Therefore, the
operator(s) must exercise good judgment and proper
safety practices to avoid damage to the equipment and
surroundings and prevent personal injury. The
instructions in this manual are intended for personnel
with a general training in operation and maintenance of
centrifugal pumps.
INSTALLATION, OPERATION AND
MAINTENANCE
In these instructions you will encounter the words
WARNING, CAUTION and NOTE. These are intended to
emphasize certain areas of personal safety and
satisfactory pump operation and maintenance. The
definitions of these words are as follows:
⚠
WARNING: An operating procedure, practice, etc.
which, if not correctly followed, could result in personal
injury, or loss of life.
⚠
CAUTION: An operating procedure, practice, etc.
which, if not strictly observed, could result in damage to,
or destruction of, equipment.
⚠
NOTE: - An operating procedure, condition, etc. which
is essential to highlight.

Safety precautions before starting pump
1. Read operating instruction and instructions supplied
with chemicals to be used.
2. Refer to a chemical resistance data chart for
compatibility of materials in pump with solution to
be used.
3. Note temperature and pressure limitations.
4. Personnel operating pump should always wear
suitable protective clothing: face mask or goggles,
apron and gloves.
5. All piping must be supported and aligned
independently of the pump.
6. Always close valves slowly to avoid hydraulic shock.
7. Ensure that all fittings and connections are properly
tightened.
Before changing application or performing
maintenance
1. Wear protective clothing as described in Item 4
above.
2. Flush pump thoroughly with a neutralizing solution
to prevent possible harm to personnel.
3. Verify compatibility of materials as stated in Item 2,
Safety Precautions above.
4. Shut off power to motor at disconnect switch.
⚠
Important:
1. Even though you have determined that CPVC is
chemically compatible with the solution, care should
be taken to protect the pump components against
unnecessary wear and physical abuse.
2. Record all models and serial numbers for future
reference. This information will be required when
contacting the Application Engineering Department.
3. Pump should be handled with care when removing
from shipping crate, or when placing pump in tank
or sump.
APPLICATION
The pump has been designed to operate safely and
reliably under normal service conditions. It is extremely
important that the pump be used within the limits
specified in the following sections of this instruction
book: The corrosion-resistant nonmetallic "wet-ends" of
the pump were designed to handle a wide variety of
liquids; however, do not use this pump on any other
service than that for which it was intended without first
checking a chemical resistance data chart and other
appropriate sources to determine its applicability and
suitability for any change in service.
