Periodic maintenance and inspection is required on all pumps to ensure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure to do so
voids warranty.
2MP Series Pumps
Refer to pump manual 1808-633-00 for General Operating and Safety Instructions.
SPECIFICATIONS
Standard units are constructed of cast aluminum with cast iron
di󰀨users, suction ange and discharge manifold. Standard
seals are EPDM/EPR with carbon/ silicon ceramic wear faces.
IMPORTANT: Not for use with petroleum based liquids.
UNPACKING
1. Remove pump from packaging materials.
2. Package should include: pump/engine mounted in roll
frame, strainer, general/safety manual, specication/parts
manual and engine manual. Pump kits: Pump end, general
safety manual and specication/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 e󰀩ciency and pump output will be
reduced if a long (>20 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
IMPORTANT: Pipe Dope/Thread Sealant must be used on all
suction and discharge connections.
1. (2) Male NPT Pipe Ports are included for use with specic
hose connections.
2. All suction hose/piping connection must be air tight.
NOTE: Pump will not prime if there are any air leaks in the
suction line or connections. Use only non-collapsible hose
or pipe on the suction.
3. If collapsible hose is used on the discharge with 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.
4. 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 o󰀨 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 classication 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 ll pump with liquid through the priming port located
on top of the discharge manifold or pump casing before
starting engine.
IMPORTANT: The pump is self-priming only when the pump is
lled with liquid.
Operation
1. Make certain pump is lled 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 ATMOSPHERE. 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.
DESCRIPTION
IPT engine driven pumps are commercial duty, centrifugal, self-priming (to 20 ft. vertical lift after initially lling casing with liquid),
portable units. Pumps are equipped with industry standard mechanical shaft seals. Iron suction and discharge manifolds are
standard NPT threads for connection to swivel hose tting with gasket or standard NPT pipe ttings. Pump components will
handle liquids with a temperature range of 40˚ to 200˚F (4˚ to 93˚ C). Pump only nonammable liquids compatible with pump com-
ponent materials. Standard pumps are close coupled to internal combustion engines manufactured by Honda, Briggs & Stratton,
Hatz, AMT specication engines and others. All engines meet current EPA emissions requirements. Pumps (70cc and larger) are
preempted from emissions regulation in California.
