SPECIFICATIONS: Maximum  specifications  refer  to  individual  attributes.  It  is  not
implied  that  all  maximums  can  be  performed  simultaneously.  If  more  than  one
maximum  is  considered,  check  with  your  CAT  PUMPS 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
[3FR-10 oz., 4FR-21 oz., 5FR-21 oz.,10FR-40 oz., 25FR-84 oz., 60FR-10 Qts.]. 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.
[25FR, 60FR] Oiler adjustment is vertical to start feed, horizontal to stop feed, 45°
to drain reservoir. 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 Tech
Bulletin 003).

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
damage  to  the  pump  base.  To  minimize  piping  stress,  use  appropriate  flexible
hose  to  inlet  and  discharge  ports.  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
recommended 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  each
degree  F  over  130°F.  Elastomer  or  RPM  changes  may  be  required.  See  Tech
Bulletin 002 or call CAT PUMPS for recommendations.

C.A.T.: Installation of a C.A.T. (Captive Acceleration Tube) 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 Dampening device onto the discharge head or in the discharge
line. Be certain the pulsation dampener (Prrrrr-o-lator) is properly precharged for the
system pressure (refer to individual Data Sheet).

A reliable Pressure 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  pressure 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. Exercise caution not to wrap tape beyond the last thread 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  pump  on  the
discharge side of the manifold. This will ensure pressure relief of the system 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
pressure  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 multiple
THERMO VALVES 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 CAT PUMPS
supplier.

STORING: For extended storing or between use in cold climates, drain all pumped
liquids from pump and flush with antifreeze solution to prevent freezing and
damage to the pump. DO NOT RUN PUMP WITH FROZEN LIQUID (refer to Tech
Bulletin 083).

Optimum performance of the pump is dependent upon the entire liquid system and will be obtained only with
the proper selection, installation of plumbing, and operation of the pump and accessories.

INSTALLATION AND START-UP INFORMATION

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 PUMPS does not assume any liability or responsibility
for the operation of a customer’s high pressure system.
