Periodic maintenance and inspection is required on all pumps to insure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure
to do so voids warranty.
IPT Series 2P5X, 2S5X & 3S5X Pumps
Refer to pump manual 1808-633-00 for General Operating and Safety Instructions.
DESCRIPTION
IPT engine driven pumps are commercial duty, centrifugal, self-priming (to 25 ft. vertical lift after initially filling casing with liquid), portable units. Pumps
are equipped with industry standard mechanical shaft seals. Iron suction and discharge manifolds are standard male NPT threads for direct connection
to swivel hose fitting with gasket, or standard NPT pipe fittings. Discharge manifold can be rotated 180˚ (in 90˚ increments); left side discharge, front
discharge, or right side discharge. Pump components will handle liquids with a temperature range of 40˚ to 180˚F (4˚ to 82˚ C). Pump only nonflammable
liquids compatible with pump component materials. Standard Pumps are close coupled to internal combustion engines manufactured by Honda, Briggs
& Stratton, & Hatz, AMT specification engines, and others. All engines meet current EPA emissions requirements. Pumps (70cc and larger) are
preempted from emissions regulation in California. Bearing housing/pedestal drive pumps are also available for direct or drive belt connection.
SPECIFIACTIONS
Standard units are constructed of cast aluminum with cast iron impeller
(“P” series - cast aluminum), cast iron volute, and cast iron suction and
discharge manifolds. Standard seals are EPDM with silicon-carbide
(“P” series – carbon-ceramic) wear faces.
UNPACKING
1. Remove pump from packaging materials.
2. Package should include: pump/engine mounted in roll frame,
strainer, general/safety manual, specification/parts manual,
engine manual. Pump kits: Pump end, general safety
manual, and specification/parts manual.
3. Make sure all components are accounted for before
discarding packaging material.
4. Inspect all components for damage.
5. No assembly is required for standard engine driven pumps.
Pump kits must be constructed on appropriate engine.
PREPARING UNIT FOR OPERATION
Placing Pump
1. Always place the pump as close to the liquid source as
possible. Priming efficiency and pump output will be reduced
if a long (>25 ft.) suction line is used. Keep all lines as short
and straight as possible. Avoid any sharp bends. Suction line
cannot have loops or high spots, hose must have a gradual
slope up to pump.
2. Pump/engine must be located on a solid level surface.
Connecting Hose or Piping
1. All suction hose/piping connection must be air tight. Pump
will not prime if there are any air leaks in the suction line or
connections.
2. Use only non-collapsible hose or pipe on the suction. If
collapsible hose is used on the discharge, the end of
discharge line is submerged in liquid, or a check valve is
placed in the discharge line, a means of venting air out of the
pump during the priming cycle must be employed.
3. Always use a suction strainer to keep large debris out of the
pump. Position strainer well below liquid surface and on a
bed of rocks or other suitable surface. If possible tie strainer
up so it is suspended off pit bottom. As a last resort tie the
strainer in a large submerged bucket if bottom of water
source is too soft or muddy.
Before Starting Engine
1. Fill engine crankcase with oil. Follow engine manufacturer
recommendations for service classification and viscosity of
oil as detailed in engine manual.
2. Fill fuel tank with clean, fresh, fuel. Follow engine
manufacturer’s guidelines as listed in engine manual.
3. Always fill pump with liquid through the priming port located
on top of the discharge manifold or pump casing before
starting engine. Remember the pump is self-priming only
when the pump is filled with liquid.
Operation
1. Make certain pump is filled with liquid before starting engine.
Failure to do so will result in damage to the mechanical shaft
seal. Never run pump dry.
DO NOT USE PUMP IN EXPLOSIVE ATMOSHERE. DO NOT PUMP
VOLATILE OR FLAMMABLE LIQUIDS.
2. Follow engine manufacturer’s starting procedure. Run
engine at full speed during priming. After pump has primed
speed may be reduced to regulate pump output.
3. Pump will self-prime to a vertical height of 10’ in less than
one minute, 20’ in 2 minutes, 25’ may take up to 4 minutes.
If pump doesn’t prime: Check for air leaks, move pump
closer to liquid, shorten suction line, remove loops and high
spots from suction line, refill pump with liquid, see
troubleshooting guide in this manual.
4. Always allow engine to cool before refueling.
After Pump is Shut Down
1. Always flush the pump out at the end of operation if the
liquid being pumped may leave a solid or sticky residue
inside of pump, or if a buildup of sediment inside the pump is
expected.
2. Always drain pump completely of liquid if there is a chance
of freezing.
Storing Pump
1. When pump is out of service for an extended period of time,
completely drain liquid from casing, store pump in a dry,
protected, well-ventilated area.
2. Add fuel stabilizer to engine fuel tank or drain fuel from tank.
Turn fuel tank valve to off position.
