SPECIFICATIONS
:
Maximum specifications refer to individual attributes. It is
not
implied that
all maximums
can be performed
simultaneousl y
. If more than one
maximum is considered, check with your CAT PUMP S supplier to confirm the proper
performance and pump selection. Refer to individual pump Data Sheet for complete
specifications, parts list and exploded view.
LUBRICATION:
Fill crankcase with special CAT PUMP oil per pump specifications
(42 oz.). DO NOT RUN PUMP WITHOUT OIL IN CRANKCASE. Change initial fill
after 50 hours running period. Thereafter, change oil every
3 months or 500 hour
intervals.
Additional lubrication may be required with increased hours of operation
and temperature.
PUMP ROTATION :
Pump was designed for forward rotation to allow optimum
lubrication of the crosshead area. Reverse rotation is acceptable if the crankcase oil
level is increased slightly above center dot to assure adequate lubrication.
PULLEY SELECTION:
Select size of motor pulley required to deliver the desired
flow from Horsepower Requirement and Pulley Selection Chart (refer to Tec h
Bulletin 003 or individual Data Sheet).
DRIVE SELECTION:
The motor or engine driving the pump must be of adequate
horsepower to maintain full RPM when the pump is under load. Select the electric
motor from the Horsepower Requirement Chart according to required pump
discharge flow, maximum
pressure at the pump
and drive losses of approximately
3-5% . Consult the manufacturer of gas or diesel engine for selection of the proper
engine size.
MOUNTING:
Mount the pump on a rigid, horizontal surface in a manner to permit
drainage of crankcase oil. An uneven mounting surface will cause extensive damag e
to the pump bas e. T o minimize piping stress,
us e appropria te flexible hos e to
inlet and discharge port s
. Use the correct belt; make sure pulleys are aligned.
Excessive belt tension may be harmful to the bearings. Hand rotate pump before
starting to be certain shaft and bearings are free moving.
LOCATION:
If the pump is used in extremely dirty or humid conditions, it is recom-
mended pump be enclosed. Do not store or operate in excessively high temperature
areas or without proper ventilation.
INLET CONDITIONS:
Refer to complete
Inlet Condition Check-List
in this manual
before starting system. DO NOT STARVE THE PUMP OR RUN DRY .
Temperatures above 130°F are permissible. Add 1/2 PSI inlet pressure per eac h
degree F over 130°F. Elastomer or RPM changes may be required. See Tec h
Bulletin 002 or call CAT PUMPS for recommendations.
C. A .T. :
Ins tallation of a C. A. T. (C aptive Acce leration Tu be) is recommended in
applications with stressful inlet conditions such as high temperatures, booster pump
feed, long inlet lines or quick closing valves.
DISCHARGE CONDITIONS:
OPEN ALL VALVES BEFORE STARTING SYSTEM to
avoid deadhead overpressure condition and severe damage to the pump or system
.
Install a
Pulsation Dampenin g
device on the discharge head or in the discharge line
as close to the head as possible. Be certain the pulsation dampener (Prrrrr-o-lator)
is properly precharged for the system pressure (see individual Data Sheet.)
A
reliable Pressur e Gauge
should be installed near the discharge outlet of the high
pressure manifold. This is extremely important for adjusting pressure regulating
devices and also for proper sizing of the nozzle or restricting orifice. The pump is
rated for a maximum pressure; this is the
pressur e
which would be
read at the
discharge manifold of the pump
, NOT AT THE GUN OR NOZZLE.
Use PTFE thread tape or pipe thread sealant (sparingly) to connect accessories or
plumbing. E xe rcis e ca ution not to wrap tape beyond the las t threa d to avoid
tape from becoming lodged in the pump or accessories. This condition will cause a
malfunction of the pump or system.
PRESSURE
REGULATION:
All systems require both a primary pressure regulating
device (i.e., regulator, unloader) and a secondary pressure safety relief device (i.e.,
pop-off valve, safety valve). The primary pressure device must be installed on the
discharge side of the pump. The function of the primary pressure regulating device
is to protect the pump from over pressurization, which can be caused by a plugged
or closed off discharge line. Over pressurization can severely damage the pump,
other system components and can cause bodily harm. The secondary safety relief
device must be installed
in-line
between the primary device and the pump
or on
the opposite side of the manifold head
. This will ensure pressure relief of the sys-
tem if the primary regulating device fails. Failure to install such a safely device will
void the warranty on the pump.
If a large portion of the pumped liquid is by-passed (not used) when the high pressur e
system is running, this by-pass liquid should be routed to an adequately sized, baffled
supply tank or to drain. If routed to the pump inlet, the
by-pass liquid can quickly
develop excessive heat and result in damage to the pump.
A temperature
control device to shut the system down within the pump limits or THERMO VALVE
must be installed in the by-pass line to protect the pump.
NOZZLES :
A worn nozzle will result in loss of pressure. Do not adjust pressure
regulating device to compensate. Replace nozzle and reset regulating device to
system pressure.
PUMPED LIQUIDS :
Some liquids may require a
flush between operations or
before storing .
For pumping liquids other than water, contact your CA T PUMP S
supplier.
SPECIA L “K ” MODELS:
Standard pumps have internal weep holes between the
V-Packings and Lo-Pressure Seals allowing the pumped liquid to cool the back side
of the packings. The “K” models do not have the internal weep holes and do not
connect to the inlet side. They have special holes on the sides of the inlet manifold
that can be fitted to an external flushing system to provide this cooling and flushing.
The “K ” models can also withstand high inlet pressures. Consult CAT PUMPS.
STORING:
For extended storing or between use in cold climates, drain all pumped
liquids from pump and
flush with antifreeze solution to prevent freezing an d
damage
to the pump. DO NOT RUN PUMP WITH FROZEN LIQUID (refer to Tech
Bulletin 083).
WARNING
All systems require both a primary pressure regulating device (i.e., regulator, unloader) and a secondary pressure safety relief device (i.e., pop-off valve, safety valve).
Failure to install such relief devices could result in personal injury or damage to the pump or to system components. CAT PUMP S does not assume any liability or responsibilit y
for the operation of a customer’s high pressure system
.
