DESCRIPTION

The Series 2000 Frame Mounted Centrifugal
Pump is an end suction centerline discharge
pump. The Series 2000 Pump’s rear pull out
construction makes servicing simpler and faster.
The hydraulically balanced impellers extend
bearing life and assure smoother, quieter
operation.

THERMAL SAFETY:

WARNING: Extreme Temperature
Hazard

If pump, motor, or piping is operating at extremely
high or low temperature, guarding or insulation is
required. Failure to follow these instructions could
result in serious personal injury or death, and
property damage.

PUMP APPLICATION

The Series 2000 Pump’s available constructions
and sizes make it ideal for applications in general
industry, water supply, water transfer, condenser,
and chilled and hot water circulation.

SAFETY INSTRUCTIONS

SAFETY
INSTRUCTIONS

This safety alert symbol will be used in this manual
and on the pump safety instruction decals to draw
attention to safety related instructions. When used
the safety alert symbol means ATTENTION!
BECOME ALERT! YOUR SAFETY IS INVOLVED!
FAILURE TO FOLLOW THE INSTRUCTIONS
MAY RESULT IN A SAFETY HAZARD.

Your Series 2000 pump should have the following
safety instruction decals located approximately as
shown. If the decals are missing or are illegible
contact your local AC Fire Pump Systems
representative for a replacement. (Fig. 1)

ELECTRICAL SAFETY:

MECHANICAL SAFETY:

WARNING: Unexpected Startup Hazard

Disconnect and lockout power before
servicing. Failure to follow these instructions could
result in serious personal injury or death, and
property damage.

WARNING: Excessive System Pressure

Hazard

The maximum working pressure of the pump is
listed on the nameplate, do not exceed this
pressure. Failure to follow these instructions could
result in serious personal injury or death, and
property damage.

WARNING: Excessive Pressure Hazard

Volumetric Expansion

The heating of water and other fluids causes
volumetric expansion. The associated forces may
cause failure of system components and release
of high temperature fluids. Installing properly sized
and located compression tanks and pressure relief
valves will prevent this. Failure to follow these
instructions could result in serious personal injury
or death, and property damage.

WARNING: Electrical Shock Hazard

Electrical connections to be made by a
qualified electrician in accordance with all
applicable codes, ordinances, and good practices.
Failure to follow these instructions could result in
serious personal injury or death, and property
damage.

WARNING: Electrical Overload Hazard

Three phase motors must have properly
sized heaters to provide overload and under
voltage protection. Single-phase motors have
built-in overload protectors. Failure to follow these
instructions could result in serious personal injury
or death, and property damage.

INSPECT PUMP SEAL
REGULARY FOR LEAKS,
REPLACE AS REQUIRED.

FOR LUBRICATION
REQUIREMENTS, CONSULT
SERVICE INSTRUCTIONS.

FAILURE TO FOLLOW
INSTRUCTIONS COULD RESULT
IN INJURY OR PROPERTY
DAMAGE.

PUMP LOCATION

Locate the pump so there is sufficient room for
inspection, maintenance, and service. If the use of
a hoist or tackle is needed, allow ample head
room.

WARNING

Eyebolts or lifting lugs if provided are for
lifting only the components to which they are
attached. Failure to follow instructions could result
in injury or death.

If lifting of the entire pump is required, do so with
slings placed as shown. (Fig. 2 & 3)

The best pump location for sound and vibration
absorption is on a concrete floor with subsoil
underneath. If the pump location is overhead,
special precautions should be undertaken to
reduce possible sound transmission, consult a
sound specialist.

If the pump is not on a closed system, it should be
placed as near as possible to the source of the
liquid supply, and located to permit installation with
the fewest number of bends or elbows in the
suction pipe.

FIG. 2 – Bases with Lifting Holes

The installation must be evaluated to determine
that the Net Positive Suction Head Available
(NPSHA) meets or exceeds the Net Positive
Suction Head Required (NPSHR), as stated by the
pump performance curve.

IMPORTANT: Do not install and operate Series
2000 Pumps in closed systems unless the system
is constructed with properly sized safety devices
and control devices. Such devices include the use
of properly sized and located pressure relief
valves, compression tanks, pressure controls,
temperature controls, and flow controls as
appropriate. If the system does not include these
devices, consult the responsible engineer or
architect before making pumps operational.

INSTALLATION

This pump is built to provide years of service if
installed properly and attached to a suitable
foundation. A base of concrete weighing 2-1/2
times the weight of the pump is recommended.
(Check the shipping ticket for pump weight.)

LEVELING

Place the pump on its concrete foundation
supporting it with steel wedges or shims
totaling 1" in thickness. These wedges or
shims should be put on both sides of each
anchor-bolt to provide a means of leveling the
base.

FIG. 4

IT IS VERY IMPORTANT THAT THE PUMP­BASE BE SET LEVEL TO AVOID ANY
MECHANICAL DIFFICULTIES WITH THE
MOTOR OR PUMP. THIS PUMP WAS
PROPERLY ALIGNED (IF FURNISHED WITH
A MOTOR) AT THE FACTORY. HOWEVER,
SINCE ALL PUMP BASES ARE FLEXIBLE
THEY MAY SPRING AND TWIST DURING
SHIPMENT. DON’T PIPE THE PUMP UNTIL
IT IS REALIGNED. AFTER PIPING IS
COMPLETED AND AFTER THE PUMP IS
GROUTED-IN AND BOLTED-DOWN, ALIGN
IT AGAIN. IT MAY BE NECESSARY TO RE­ADJUST THE ALIGNMENT FROM TIME TO
TIME WHILE THE UNIT AND FOUNDATION
ARE NEW.
