STARTING
Follow the motor manufacturer's instructions
carefully. Before starting, fill the pump casing with
liquid through the priming plug provided. Your
pump has been designed to prime itself in a few
minutes. High suction lifts require additional time
and reduce the performance of the pump. Should
you have difficulty, refer to the "Trouble Guide"
paragraph.
SAM self-priming pumps prime and re-prime
themselves providing the casing is filled with
liquid. Should you lose this liquid from the casing
accidentally or by draining purposely, it will be
necessary to fill casing with liquid before starting.
Check drive coupling and V belt alignment. (Refer
"coupling alignment" for instructions).
Check motor wiring.
WARNINGS:
All electrical work must be done by a licensed
electrician.
Before working on pump and/or motor be certain
that the electrical power is off at the main junction
box.
Disconnect the fuse or circuit breaker and have the
main switch tagged "DO NOT ENERGISE THIS
SWITCH PERSONNEL WORKING ON EQUIPMENT."
Some motors are equipped with built-in thermal
overloads to shut off the motors in the event the
temperature becoming excessive (as a result of low
voltage, poor ventilation, overloaded lines, etc.)
These motors will restart automatically as the
motor cools down. For safety sake, DO NOT work
on any motor without shutting off the electricity.
Never operate an electric motor driven pump
without properly grounding the motor frame.
Serious injury or death by electrocution could
result.
Drain pump casing completely before taking pump
apart. It is advisable to flush the inside of the
casing with water before taking pump apart.
Never start pump before putting back all necessary
guards such as coupling guard and/or belt guard.
LUBRICATION
Bearing lubrication: (Refer to drawing)
Use good grade SAE #30 non-detergent motor oil.
Units are shipped without oil and must be filled
before starting. Fill bearing housing oil cavity with
oil through "filter" provided on top of bearing
housing nearest motor until oil starts to drip out of
"oil level" hole. ("Oil Level" cast on housing). Install
breather to vent any oil vapour.
Also, provision is made on the housing to install
"constant level oiler." ("Oiler" cast on housing.) This
oiler can be supplied as an optional item. Under
normal service, drain and refill housing cavity oil
yearly. However, oil level should be checked
regularly.
BEARING CAVITY OIL CAPACITY:
3DTH & 4DTH
:56 fl. oz.
6ETH :68 fl. oz.
8GTH :68 fl. oz.
10GTH
:68 fl. oz.
Seal cavity lubrication
Use good grade SAE #30 non-detergent motor oil.
Fill seal cavity with oil through hole provided on
top of bearing housing nearest pump casing, until
you see oil through hole opening. Install breather
to vent any oil vapour.
NOTE: It is recommended that the seal cavity oil be
drained (through the drain hole) and replaced with
clean grade SAE #30 non-detergent motor oil every
6 months.
The mechanical shaft seal is a wearing part that
will eventually need to be replaced. A leaky seal
must be replaced quickly to prevent damage to the
pump. Any overflow of liquid through the breather
(vented plug) is an indication of a possible seal
failure.
