General Information Pump Foundation

Location:
Locate the pump as near the water source as practical. Make
the pipe run as short and straight as possible, especially if a
suction lift is required.
Careful attention should be taken to assure that net positive
suction head available (NPSHA) exceeds net positive suction
head required (NPSHR) by the pump or reduced performance
and severe pump damage may result. If in doubt, check
with your nearest Berkeley professional dealer. Install pump
in a clean, dry and drained location readily accessible for
inspection and maintenance. Provide ample ventilation.

Foundation: Refer to illustrations at right.

Heavy weights. Use care and proper
equipment when handling pump for installation. Pump should
be set on a concrete foundation which is sufficiently substantial
to absorb vibration and which provides a permanent and rigid
support.

Piping:
System piping should be at least one commercial pipe size
larger than pump connections and flow velocity should not
exceed eight (8) feet per second. In pool installation, flow
velocity should not exceed six (6) feet per second.
NOTICE: Take care to align piping with pump case.
Misalignment or excessive pipe strain can cause distortion of
pump components resulting in rubbing, breakage and reduced
pump life.
Support pipe in such a way that no force is exerted on pump
connections. Check alignment as follows: with the pump shut
down and isolation valves closed, remove pipe flange bolts.
If the mating flanges come apart or shift, misalignment is
present and causing pressure on the connections. Adjust pipe
supports until flanges mate without any force. This procedure
can be done throughout piping system.

SUCTION PIPING:
Refer to Pages 10 and 11 for installation instructions for
swimming pool circulating pump applications. Refer to Pages
6 through 9 for recommended and not recommended practices
in suction connections in centrifugal installations.

Discharge piping:
Refer to illustrations on Page 12 and 13 for recommended and
not recommended practices in discharge connections.

ELECTRICAL CONNECTION:
Hazardous voltage. Can shock, burn, or
cause death. All wiring should be done by a qualified
electrician. Disconnect power to pump before servicing.
• There are several types of permanent pump/ foundation
Check voltage and phase stamped on pump motor nameplate installations in use. Those pictured above are typical.

CAUSE CORRECTIVE ACTION

I. ELECTRICAL
A. No voltage in power system Check phase-to-phase on line side of starter contactor.
Check circuit breaker or fuses.
B. No voltage on one phase Check phase voltage on line side of starter contactor. Isolate open circuit
(Three Phase Units) (circuit breaker, fuse, broken connections, etc.)
C. Low voltage at motor Running voltage across each leg of motor must be ±10% of nominal
voltage shown on nameplate.
D. Motor leads improperly grouped Refer to lead grouping diagram on motor nameplate.
for voltage
E. Control failure Check control device, starter contactor, H-O-A selector switch, etc.,
for malfunction.
F. Thermal overload switch open Check phase-to-phase on line side of starter contactor.
G. Installation failure Check motor or windings to ground with megohmmeter.
H. Open windings Check leg-to-leg with ohmmeter.
I. Frequency variation Check frequency of power system. Must be less than 5% variation from
motor nameplate rating.
II. MECHANICAL
A. Flow through pump completely or Locate and remove obstruction. Refer to Repair Instructions
partially obstructed for disassembly.
B. Wrong direction of rotation Reverse rotation of three phase motor by interchanging any two leads.
See manufacturer’s Instructions for reversing single phase motor.
C. Pump not primed Reprime. Inspect suction system for air leaks.
D. Internal leakage Check impeller for wear of controlled clearances (See Repair Instructions).
E. Loose parts Inspect. Repair.
F. Stuffing box not properly adjusted Adjust gland.
III. SYSTEM
A. Pressure required by system at design Compare pump pressure and flow rate against pump characteristic curve.
flow rate exceeds pressure rating of pump Check for closed or partially closed valve in discharge piping system.
Reduce system pressure requirement. Increase pressure capability of pump.
B. Obstruction in suction piping Locate and remove obstruction.
C. Pressure rating of pump exceeds pressure Compare pump pressure and flow rate against pump characteristic curve.
requirement of system at design flow rate Inspect discharge piping system for breaks, leaks, open by-pass valves, etc.
If necessary, reduce flow rate by partially closing discharge valve.

Limited Warranty
BERKELEY warrants to the original consumer purchaser (“Purchaser” or “You”) of the products listed below, that they will be free
from defects in material and workmanship for the Warranty Period shown below.
Product Warranty Period
Water Systems:
whichever occurs first:
Water Systems Products — jet pumps, small centrifugal pumps, submersible pumps and
12 months from date of original installation, or
related accessories
18 months from date of manufacture
Pro-Source™ Composite Tanks 5 years from date of original installation
Pro-Source™ Steel Pressure Tanks 5 years from date of original installation
Pro-Source™ Epoxy-Lined Tanks 3 years from date of original installation
12 months from date of original installation, or
Sump/Sewage/Effluent Products
18 months from date of manufacture
Agricultural/Commercial:
Centrifugals – close-coupled motor drive, frame mount, SAE mount, engine drive, VMS, SSCX, 12 months from date of original installation, or
SSHM, solids handling, submersible solids handling 24 months from date of manufacture
12 months from date of original installation, or
Submersible Turbines, 6” diameter and larger
24 months from date of manufacture

Our limited warranty will not apply to any product that, in our sole judgement, has been subject to negligence, misapplication,
improper installation, or improper maintenance. Without limiting the foregoing, operating a three phase motor with single phase
power through a phase converter will void the warranty. Note also that three phase motors must be protected by three-leg,
ambient compensated, extra-quick trip overload relays of the recommended size or the warranty is void.
Your only remedy, and BERKELEY’s only duty, is that BERKELEY repair or replace defective products (at BERKELEY’s choice). You
must pay all labor and shipping charges associated with this warranty and must request warranty service through the installing
dealer as soon as a problem is discovered. No request for service will be accepted if received after the Warranty Period has
expired. This warranty is not transferable.
BERKELEY SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAMAGES WHATSOEVER.
THE FOREGOING LIMITED WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES,
INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE FOREGOING LIMITED WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION PROVIDED HEREIN.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on the duration of an
implied warranty, so the above limitations or exclusions may not apply to You. This warranty gives You specific legal rights and You
may also have other rights which vary from state to state.
This Limited Warranty is effective June 1, 2011 and replaces all undated warranties and warranties dated before June 1, 2011.
