DESCRIPTION
This pump is recommended for use in basins or lift stations and suitable
for pumping sewage, effluent, wastewater and other non-explosive, non-
corrosive liquids. It has 2" spherical solids-handling capability.
Automatic operation can be achieved with the use of the tethered float
switch. Other accessories such as basins, check valves, and covers are
also available.
SPECIFICATIONS
Discharge: 2" FNPT vertical
Intake: 2" diameter opening
Housing: Cast iron
Volute: Cast iron
Impeller: Vortex design nylon, with pressure relief vanes
Motor: PSC, 3500 RPM, with automatic reset thermal overload protection
Hardware: 300 series stainless steel
Bearing: Double shielded ball
Shaft seal: Mechanical, spring loaded, stationary carbon with Nitrile boot
and rotating ceramic seat
Cooling: The motor housing contains a cooling oil to provide cooling for
the motor and to lubricate bearings and seals. These pumps are capable of
operating with the motor housing partially exposed for extended periods of
time, providing sufficient motor cooling and bearing lubrication. However,
for the best cooling and longest motor life, the liquid level being pumped
should normally be above the top of the cast iron motor housing.
SAFETY GUIDELINES
RISK OF ELECTRIC SHOCK: This pump is supplied with a grounding
conductor and grounding-type attachment plug. To reduce the risk of
electric shock, be certain that it is connected only to a properly grounded,
grounding-type receptacle.
Your pump is equipped with a 3-prong electrical plug. The third prong
grounds the pump to prevent possible electrical shock hazard. Do
not remove the third prong from the plug. A separate branch circuit is
recommended. Do not use an extension cord.
When a pump is in a basin or lift station, do not touch motor, pipes, or
water until unit is unplugged or shut off. If shut-off box is not accessible,
call the electric company to shut off service to the house, or call your local
fire department for instructions. Failure to follow this warning can result in
fatal electrical shock.
Do not modify the power cord except to shorten it to fit into a control panel.
Any splice between the pump and the control panel must be made within
a junction box and mounted outside of the basin, and comply with the
National Electrical Code. Do not use the power cord for lifting the pump.
The pump motor is equipped with an automatic resetting thermal protector
and may restart unexpectedly. Protector tripping is an indication of motor
overloading as a result of excessively high or low voltage, inadequate
wiring, incorrect motor connections, or a defective motor or pump.
Read all instructions and safety guidelines thoroughly. Failure to follow
the guidelines and instructions could result in serious bodily injury and/or
property damage.
DO NOT USE TO PUMP FLAMMABLE OR EXPLOSIVE FLUIDS SUCH AS
GASOLINE, FUEL OIL, KEROSENE, ETC. DO NOT USE IN EXPLOSIVE
ATMOSPHERES OR HAZARDOUS LOCATIONS AS CLASSIFIED BY NEC,
ANSI/NFPA70. FAILURE TO FOLLOW THIS WARNING CAN RESULT IN
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
During normal operation the pump is immersed in water. Also, during rain
storms, water may be present in the surrounding area of the pump. Use
caution to prevent bodily injury when working near the pump:
Remove the plug from the receptacle prior to touching, servicing, or
repairing the pump.
To minimize possible fatal electrical shock hazard, use extreme care when
changing fuses. Do not stand in water while changing fuses or insert your
finger into the fuse socket.
Do not operate the pump in a dry basin. This will cause the pump to
become extremely hot, causing burns if touched and/or damage to the
pump.
Do not oil the motor. The pump housing is sealed. A high grade dielectric
oil devoid of water has been put into the motor housing at the factory. Use
of other oil could cause serious electric shock and/or permanent damage
to the pump.
This pump’s motor housing is filled with a dielectric oil for motor heat
transfer and lifetime lubrication of the bearings. This oil is non-toxic to
aquatic life. However, suffocation can occur if oil is left on the water
surface. If oil escapes the motor housing it can be removed from the
surface quickly by placing newspapers on the water surface to soak up
the oil.
INSTALLATION
Pump must be installed in a suitable, gas-tight basin that is at least 18" in
diameter and 30" deep, and vented in accordance with local plumbing
codes.
This pump features a 2" female NPT discharge.
Pump can be installed with ABS, PVC, polyethylene or galvanized steel
pipe. Proper adapters are required to connect plastic pipe to pump.
Pump must be placed on a hard level surface. Never place pump directly
on clay, earth or gravel surfaces.
A check valve must be used in the discharge line to prevent backflow of
liquid into the basin. The check valve should be a free flow valve that will
easily pass solids.
CAUTION: For best performance of check valves when handling solids,
install in a horizontal position or at an angle of no more than 45°. Do not
install check valve in a vertical position as solids may settle in valve and
prevent opening on start-up.
When a check valve is used drill a 3/16" hole in the discharge pipe
approximately 1" to 2" above the pump discharge connection and below
check valve to prevent air locking of the pump.
ELECTRICAL CONNECTIONS
Check local electrical and building codes before installation. The installa-
tion must be in accordance with their regulations as well as the most
recent National Electrical Code (NEC).
To conform to the National Electrical Code all pumps must be wired with
14 AWG or larger wire. For runs to 250', 14 AWG wire is sufficient. For
longer runs, consult a qualified electrician or the factory.
