The patented Little Giant magnetic drive pump design consists of a cylindrical drive magnet attached to the motor
shaft which rotates around a stainless steel separator housing. Inside this housing is a magnet completely
encapsulated in stainless steel, and fixed to the impeller. The impeller assembly is free to rotate on a spindle that is
supported at both ends. The spindle is held captive and does not turn. Front and rear thrust washers are utilized as
wear bearings. The washers are held captive and do not revolve. This prevents wear on the shaft. Inside this
housing is a magnet fixed to the impeller. With the magnetic coupling the motor drives the impeller. This coupling
eliminates the conventional shaft seal and its possibility of leakage.
These models utilize a carbon bushing between the impeller and spindle. The use of this carbon bushing will allow
these pumps (SC & HC) to run dry (without fluid) for up to 8 hours with no apparent detrimental harm to pump.All
wetted parts can be serviced by removing (6) bolts which hold the volute to the housing. The pump head
components can easily be replaced in the field if necessary.
•
• • The plastic magnet housing on the SS series pumps is glass filled Ryton
and the captive thrust washers (front and rear) are alumina ceramic. If one side of thrust washer has a small black
• •
dot or indentation mark, the reverse side is polished. The polished side interfaces with the spinning impeller. The
•
o-ring seal is Viton
• •
eight hours.
• •
• •
Your Little Giant pump is delivered to you pretested from the factory. In order to prevent damage to the ceramic
• •
impeller shaft during shipping, the impeller (item 4) has not been assembled within the pump head. The pump may
• •
be installed in any position. It may be mounted vertically with the pump head down. Proper plumbing connections
should be made. See specification table to determine what size intake and discharge your pump has. Use a thread
• •
sealer on all pipe connections and hand tighten only. Note: a roll of Teflon
• •
wrench to tighten the connections. Excessive force may damage the plastic part. Make sure the bolts are tight
• •
before operating the pump.
•
Motor nameplate lists all data. Make sure the pump is wired per diagram under wiring compartment cover.
These pumps are not submersible. Operate the pumps only in the in-line mode. Do not put the units in liquid. Pump
should be installed in a dry area and protected from splash. These pumps are not self priming models. They must
be installed so that the pump head (volute) is flooded at the time the pump is to be started. Do not restrict the intake
side of the pump. Connections on the intake side should not be of smaller inside diameter pipe or tubing or hose
• •
than the intake inside diameter of the intake thread designation. If reduced flow is required restrict the discharge
side. Installing a valve or other type of restriction device on the discharge side is the proper method for reducing
flow from the pump. When using a valve the pump can be throttled to provide various flow rates and pressures
without harming the motor or the pump parts.
The pump should not be installed in a manner that will subject it to splashing or spraying.
CAUTION: INSTALLATION
For connection to discharge and intake on all Ryton
Wrench will crack volute.
Make certain that the unit is disconnected from the power source before servicing. Servicing should be performed
only by a service center or qualified electrician.
1. The motor contains ball bearings which do not require lubrication.
2. All wetted parts can be serviced by removing the (6) bolts (item 9) which hold the volute to the housing. The
pump head components can easily be replaced in the field if necessary.
3. Lightly clean any corrosion or debris which may clog the impeller.
4. If pump is tripping circuit breakers, GFCI, or not operating properly after cleaning, return to Little Giant. DO
NOT attempt repairs yourself.
