SAFETY GUIDELINES
EN
CAUTION: To reduce the risk of electrical shock, pull plug before
servicing this 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.
This pump must be properly grounded while in use to protect the
operator from electrical shock.
During operation the area surrounding the pump may be covered
with water. Take care when handling the pump. Do not disconnect
the plumbing connections when pump is in operation.
Do not stand in water when changing fuses.
PumP construction
The patented Little Giant magnetic drive pump design consists of a
cylindrical drive magnet attached to the motor shaft, which rotates
around a chemical resistant plastic separator housing. Inside this
housing is a magnet completely encapsulated in chemical resistant
plastic, and is 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. One side of each
washer has a polished surface and interfaces with the spinning
impeller. The other surface is not polished and is identified by
a black dot, white dot, or indentation mark. With the magnetic
coupling the motor drives the impeller. This coupling eliminates
the conventional shaft seal and its possibility of leakage.
The CK series handles highly corrosive chemicals at elevated
temperatures because of the unique materials used in its
construction.
The CK models utilize a chemloy bushing between the impeller
and spindle. DO NOT allow pump to run dry (without fluid in pump
head).
All wetted parts can be serviced by removing 6 bolts that hold the
volute to the housing. The pump head components can easily be
replaced in the field if necessary.
PumP materials
The plastic parts on the CK series pumps are carbon filled PVDF.
The spindle shaft, which is stationary, and the captive thrust washers
(front and rear) are alumina ceramic or silicon carbide. If one side
of thrust washer has a small black dot, white dot, or indentation
mark, the reverse side is polished. The polished side interfaces with
the spinning impeller. The O-ring seal is Fluoroelastomer (FKM) or
PTFE.

installation
Your Little Giant pump is delivered to you completely pre-
assembled and pre-tested from the factory. It is ready for
immediate use. 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 PTFE pipe seal tape is supplied. Do not use a 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. That
is, the inlet of the pump must be below the level of the surface
of the liquid being pumped (Figure 1). 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.
CAUTION: For connection to discharge and intake on all PVDF
pumps, use PTFE tape and hand tighten only. Using a wrench will
crack the volute.
The pump should not be installed in a manner that will subject it to
splashing or spraying.
