OPERATION
16
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 as necessary. To anchor the pump, attach anchored
tie-down straps to the pump lift handles.
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.
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
noncollapsible. Never use hoses that are smaller than the suction or
discharge fittings. Example: 2 inch pump requires a 2 inch inside
diameter or greater hose and 3 inch pump requires a 3 inch inside
diameter or greater 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.
