General Information
Installation
LOCATION
Locate the pump as near the water source as practical. Make
pipe run short, straight and with as few pipe fittings as pos-
sible, to keep total friction loss to a minimum.
Install pump in a clean, dry and drained location if possible
and protect against moisture and adverse weather conditions.
Pump should be located on a level, hard surface to prevent
shifting or tipping. Locate to be readily accessible for in-
spection and maintenance.
Because of the portable nature of this style pump, 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.
Figure 1, illustrates where these terms (NPSHA / NPSHR)
come from, and how to determine if the pumping conditions at
which you want to operate meet the proper criteria. When in
doubt, consult your nearest Berkeley Professional Dealer.
NOTE: If pump site is 1000 feet above sea level, subtract 1.2
feet from the NPSHA equation and an additional 1.2 feet for
each additional 1000 feet of elevation.
PUMP FOUNDATION
CRUSHING WEIGHT. Models with larger
suction and discharge openings are extremely heavy. Use care
and proper equipment when handling pump for installation.
Be sure to allow for the weight of the water in the pump and
piping.
Portable Installation:
Pump should be placed on an area that will provide a solid
foundation substantial enough to support the weight of pump
and engine and also to provide stability while the pump is
running. Engine vibration will cause shifting on any type of
loose surface and cause piping strains and possible damage.
NOTICE: Settling and/or shifting during operation can cause
piping to place excessive strain on the pump and may
damage pump case.
Permanent Installation:
Pump and Engine should be set on a concrete foundation
which is sufficiently substantial to absorb vibration and which
will provide a permanent and rigid support. Bolt engine directly
to concrete.
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.
Misalignment of piping with pump case or
excessive pipe strain can cause distortion of pump com-
ponents resulting in rubbing, breakage and reduced pump life.
Insure that piping is supported in a manner that prevents the
exertion of force on pump connections. If ANSI type flange
connections are used, this can be checked by the following
procedure. With the pump shut down, 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.
