OPERATION
SAFE OPERATING PRECAUTIONS
Before operating the pump for the first time, please review
IMPORTANT SAFETY INFORMATION (page 2) and BEFORE
OPERATION (page 3).
For your safety, avoid starting or operating the engine in an enclosed
area, such as a garage. Your engine’s exhaust contains poisonous
carbon monoxide gas, which can collect rapidly in an enclosed area
and cause illness or death.
Do not pump drinking water. Pump only non-potable water, muddy
water, and water containing solids. Pumping flammable liquids, such
as gasoline or fuel oils, can result in a fire or explosion, causing
serious injury. Pumping sea water, beverages, acids, chemical
solutions, or any other liquid that promotes corrosion can damage the
pump.
Due to the pump diaphragm reciprocating motion, pump assembly
and hoses will move up and down and side-to-side during pumping.
This may cause the pump to walk or move around while pumping.
Depending on the surface conditions, pump hose length, and other
factors, it may be necessary to anchor the pump to limit pump
movement. During operation, observe pump movement and anchor
the pump frame and wheels as necessary.
• Attach anchored tie-down straps to the pump frame.
• Place blocks in front and behind the wheels.
• Try to locate the pump on a level surface.
While pumping, the suction hose may move out of the pumping
source, and the discharge hose may move away from the pumping
destination. It may also be necessary to anchor hose ends to prevent
hose movement.
If there is no one to monitor the pump during operation, it is advisable
to anchor the pump to prevent unexpected movement.
Pump total dynamic discharge head is 50 feet. Total dynamic
discharge head includes static discharge head (discharge vertical
height) and head loss due to friction. Head loss makes it impractical
for the static discharge head to exceed 25 feet. Pumping to a static
discharge head greater than 25 feet can damage the pump. See the
Pump Performance Curve on page 19.
This diaphragm pump should never be run with the discharge output
shut off or restricted.
NOTICE
Pump case failure may result if the discharge output is shut off or
restricted. To avoid pump damage, do not restrict, shut off, or
momentarily stop the fluid flow from the discharge hose.
A rigid pipe should never be used with a diaphragm pump. Flexible
hoses must be attached to the pump. The suction hose must be non-
collapsible. Never use hoses that are smaller than the suction or
discharge fittings.
This pump requires a 3 inch inside diameter or larger hose. Using
rigid pipes or hoses that are too small will cause severe damage to
the diaphragm pump.
NOTICE
Due to pump movement during operation, connecting a rigid pipe to
the pump will cause pump damage. Always use flexible suction and
discharge hoses to prevent pump damage.
When water being pumped contains solids, the solids may get lodged
under the clappet valves, which will prevent the clappet valves from
closing completely. To maintain maximum pump performance, the
discharge hose should angle upward as it exits the pump.
If the discharge hose must run across a roadway, the hose should
cross the roadway perpendicular to traffic flow. Also, heavy boards
should be placed next to the hose so the motor vehicle weight does
not shut off the discharge as vehicles cross over the hose.
Driving over a discharge hose while the pump is running, or even
possibly when the pump is stopped, will most likely cause pump case
failure.
NOTICE
Collapsing the discharge hose will cause pump case and/or
diaphragm damage. To prevent pump damage, take the necessary
precautions to prevent the discharge hose from getting compressed
or collapsed.
During freezing weather, always drain the pump case after use. If
water is left in the pump case during freezing weather, the pump case
will break.
