Please read this instruction
manual carefully before install-
ing your new system as failures
caused by incorrect installation
and operation are not cover by
the warranty.
1. Application
1.1. The TPHK series is multi-stage centrif-
ugal pump designed for industrial use,
especially for machine tools.
1.2 The pump can not be used to transfer
explosive liquids; such as gasoline,
diesel oil or similar liquids. It is suitable
to carry liquids such as water, coolant,
low viscosity or other non-corrosive
liquids.
2. Product Code Designation
The standard range of pumps includes
complete impeller in chamber combina-
tions. Upon request, a special length can
be supplied by fitting empty intermediate
chambers instead of standard chambers
with impellers. The pump nameplate
indicates the number of chambers and
impellers fitted to the pump.
3. Operating Limits
1. Ambient temperature : Max. 40°C(104°F)
2. Liquid temperature range :0°C (32°F) to
90°C (194°F)
3. Operating pressure : Max. 10 kg/cm²
4. Submerged depth : Min. 40mm
5. Stainer Diameter : Ø2mm (TPHK2T,4T)
Ø3mm(TPHK8T,12T)
6. Particle Size : 2mm (TPHK2T,4T)
3mm (TPHK8T,12T)
7. Liquids (maximum content of solid
particles in suspension 50g/m³)

4. Installation
The pump has hot surface on the
motor. It must be installed so that
persons cannot accidentally come
into contact the hot surface.
4.1. Submerged Depth
To avoid dry running and damage the
pump during operation, the minimum
pump submerged depth is 40mm (15
/
8”)
as shown in Fig 1. In addition, the bottom
of the pump suction inlet must be at least
25 mm (1”) above the bottom of the tank.
4.2. The motor protector shall be installed by
the user.
5. Electrical Connection
5.1 The electrical connection should
be carried out in accordance with
local regulations. Never make any
connections unless the electricity
supply has been switched off.
5.2. The electrical hazard warning
mark is placed outside the
connection box. Be careful.
5.3. Electrical data (voltage and frequency)
are shown on the pump nameplate.
Verify if these data match your electricity
supply. A circuit breaker should be
installed and the grounding be properly
connected for your safety.

5.4. Make electrical connection in accor-
dance with connecting diagram
located inside the connection box. The
motor current must be within the rated
amps range indicated on nameplate.
Three phase motor requires a magnet-
ic starter for safety.
5.5. For three phase motors, please check
the correct direction of rotation of the
pump on the motor fan cover. When
seen from motor fan cover end, the
pump should rotate clockwise. You
can reverse the direction of rotation by
interchanging any two of the incoming
supply wires.
5.6. For your safety, be sure the Residual
current device (RCD, 30mA) is in your
system and grounding is properly
connected to prevent from electric
shock.
5.7. If the supply cord is damaged, it must
be replaced by the manufacturer, its
service agent or similary qualified
persons in order to avoid a hazard.
5.8. The user shall install a over-load
protection device for the pump runing.
6. Start-up
Before starting the pump, make sure the
following:
6.1. For three phase motors, verify if the
rotating direction is correct. It should
be clockwise viewing from the motor
fan cover end.
6.2. All piping joints are completely tight.
Leakage in piping may cause the
pump hydraulic loss.
6.3. The pump is filled with liquid.
6.4. The suction filter is not blocked by any
foreign bjects.
7. Operation and Maintenance
It is dangerous to operate the
pump against a closed
discharge outlet because it will
cause extremely high liquid flow
temperature and damage the
pump in a few minutes.
7.1. Lubrication
The mechanical seal and shaft sleeves
are lubricated by the pumped liquid.
7.2. Suction filter
Always keep suction filter clean and
make sure it is not blocked by impuri-
ties.
7.3. Periodic checks
The following checks should be carried
out periodically to ensure the normal
operation.
7.3.1. Check the quantity of liquid and
operating pressure.
7.3.2. Check there are no leaks on piping
joints.
7.3.3. Check the tripping of the motor
starter.
7.3.4. Check that all controls are functi
oned normally.
7.4. When pump is not in use for a period,
it should be drained. For start up after
long time inactivity please check if the
impeller and mechanical seal are free.
If they are locked up by sand, rust or
something else please clean them up.
7.5. The pump must not be used to transfer
explosive liquids. In systems with hot
liquids (over 60°C), extra caution
should be exercised to prevent from
personal injury.
7.6. The pump should not be used to trans-
fer toxic or contaminated liquids.
Please carefully follow all instructions
in the manual as Walrus may refuse to
accept the contaminated pump for
servicing.
