Please read this installation and
operating instructions carefully
before beginning installation
and operation.
1. Application
1.1 The TPRK Series is multi-stage
centrifugal pump designed for
transferring liquid used in machine
tools.
1.2 The pump can not be used to transfer
explosive liquids, such as gasoline,
diesel oil and other similar liquids. It
is only suitable for water diluted, low
viscosity, uncorrosive cooling or
lubricant liquids.
2. Model Explanation
The pump models are coded based
on the number of pump stages.
Standard stages consist of both
diffusers and impellers, and null
stages, for special installation
considerations, contain diffuser
chamber only. The pump model is
shown on the pump nameplate.
3. Technical Data
Liquid Temperature:+0oC~+90oC
Ambient Temperature: Max.+50oC
Enclosure Class: IP55
Discharge Pressure: Max.25kg/cm2
4. Installation
The motor surface temperature
is extremely high. It must be
mounted in the save place to
avoid accidental touch.
4.1 Submerged Depth
To avoid dry running and damage the
pump during operating, the minimum
pump submerged depth is 65mm, as
shown in Fig.1.In addition, a
minimum 25mm gap between pump
suction inlet and tank bottom is
required to allow for sediment build
up.

5. Electrical Connection
5.1 Electrical installation should be
carried out in accordance with
the local electrical code. Make
sure that the electricity supply
has been switched off before
electrical connetion.
5.2 Resulting in electrical hazard
warning mark has been
marked outside the connecting
box. Be careful.
5.3 Electrical specifications (voltage,
hertz) are shown on the pump
nameplate. Verify that the power
supply voltage and hertz match
pump requirement. An external
ON/OFF switch must be installed.

~ 3 ~
5.4 Electrical connection should be in
accordance with diagram shown on
connecting box, and motor current
should be within rated amps as
shown on nameplate. Three phase
pump requires extra magnetic starter
with protection.
5.5 Three phase motor must check
rotating direction. The rotating
direction indicated on the fan cover,
is clockwise viewing from fan cover
end. Interchanging any two leads
with power off can reverse the pump
rotation.
6. Start-Up
Before start the pump, re-verify the
following items.
6.1 Verify if three phase pump rotation is
correct. The rotating direction should
be counterclockwise viewing from
fan cover end.
6.2 Piping and joints should be fitted
carefully to prevent leak. Leak in the
piping will cause the pump hydraulic
lost.
6.3 The pump has been filled with liquid.
6.4 NO any foreign objects block the
suction filter
6.5 For start up of the first operation or
after long time inactivity, please
place a screwdriver against the shaft
at motor end and following the
sticker instruction turn clockwise or
anticlockwise to see if rotor spins
freely. (Fig. 2). If it is, you are free to
run the pump.
7. Operation and Maintenance
The pump can be operated
under the fully closed of
discharge outlet continuously,
because it will raise the liquid
temperature abnormally, and
damage the pump after 5 minutes.
7.1 Lubrication
The mechanical seal and shaft
sleeves inside the pump are
lubricated by working liquid.
7.2 Suction Filter
Suction filter should be always kept
clean to make sure no any foreign
objects block the filter in order to
have best performance.
7.3 Periodic Examination
The following check items should be
carried out periodically to ensure the
normal operation.
7.3.1 Check the discharge and output
pressure of working liquid.
7.3.2 Check the leak of piping and
joints.
7.3.3 Examine the motor starter
/container.
7.3.4 Test all the pump control
function.

9. Attention, when the pump
carried, we suggest you the
way to carry pump as below:

7.4 The pump can not be used to transfer
explosive liquids. Extra protective is
required if the working liquid
temperature exceeds 60 to avoid
scald hazard.
7.5 The pump should not be used in the
transferring of toxic or contaminated
liquid. Service and maintenance will
not be provided, if the pump
application is not in compliant with
the installation and operation
procedures. The use must take the
responsibility for damage.

10. Trouble Shooting
Make sure electricity supply has been switched off before trouble shooting
