Priming The Pump - Flotec FP5112 Manual Del Usuario

Installation
BEFORE YOU INSTALL YOUR PUMP
Pump clean water only with this pump.
NOTICE: This unit is not designed for applications involv-
ing salt water or brine! Use with salt water or brine will
void warranty.
To avoid clogging the pump and damaging the shaft seal,
do not pump water containing solids, foreign material,
sand, silt, or abrasives. Always have the suction strainer
installed when the pump is operating. Failure to use a
strainer may cause the pump to fail and void the warranty.
Clean the strainer and flush out the pump after each use.
Make sure all of the hose and pipe connections in the
suction line are tight. An air leak in the suction line will
prevent the pump from priming and reduce pump perfor-
mance.
To prevent damage to pump materials, do not use pipe
joint compounds on pump ports. Use only PTFE pipe
thread sealant tape to seal the threads.
Tighten all of the piping joints to the pump hand tight
+1½ turns only. Overtightening may break the pump and
will void the warranty.
Do not allow the pump or any system component to
freeze. Freezing will void the warranty.
Periodically inspect the pump and the system components.

PRIMING THE PUMP

All suction connections must be airtight. Make sure the
suction lift is not more than 25 feet (7.6M).
NOTICE: 'Priming' refers to the pump expelling all air in
the system and beginning to move water from its source
out into the system. It does not refer only to pouring
water into the pump (although pouring water in is usu-
ally the first step).
Risk of burns. NEVER run the pump dry.
Running the pump without water may cause pump to
overheat, damaging seal and possibly causing burns
to persons handling the pump. Running pump without
water can damage the impeller and may damage the
seal, causing leaking or flooding, and will void the war-
ranty. Fill the pump with water before starting it.
Follow the steps below:
1. Remove the priming plug.
2. Make sure the suction and the discharge valves and
any hoses on the discharge side of the pump are open.
3. Fill the pump and suction pipe with water
4. Replace the priming plug, using Teflon tape on the
thread; tighten the plug.
NOTICE: If a priming tee and plug have been pro-
vided for a long horizontal run, be sure to fill the suc-
tion pipe through this tee and replace the plug. (Use
Teflon tape on the plug.)
5. Start the pump; water should be produced in 10
minutes or less. The time will depend on the depth

to water. If no water is produced within 10 minutes,
stop the pump, release all the pressure, remove the
priming plug, refill the ports and pipe and try again.
Pumping From Lakes, Streams, and Ponds
Locate the pump as near as possible (vertically) to the
water source, to keep the suction lift (distance from the
water to the pump) as low as possible. Place the pump
on level support. Protect against excess moisture and
flooding.
Long pipe runs and many fittings increase friction and
reduce flow. Use the smallest possible number of fittings
and the shortest possible run for piping.
Support the weight of the pipe.
Be sure the water is clear of debris which can clog the
pump, such as sand, dirt, or scale. Be sure the foot valve
and the pipe are clean and in good condition; scale or
dirt in the foot valve can cause the valve to leak. Valve
leakage may cause the pump to lose its prime, which
can result in pump failure.
Piping
Both the suction and discharge ports are tapped for 1"
BSP threads. If using hoses, use a hose adapter. See
Figure 1. Do not use a hose on the suction if pumping
from lakes, streams or ponds. The hose will collapse and
cause pump failure. Install a strainer with the foot valve
on the end of the suction line. Inspect and clean the
strainer frequently (Figure 1).

NOTICE: An air leak in the suction pipe may draw air in
although no water leaks out. Make sure there are no air
leaks or air pockets in the suction pipe.
