mounted on extended motor shaft. All parts in
contact with the pumped liquid are made of
stainless steel.

1.3 Operation conditions:

1. Ambient temperature: Max. 40°C

2. Liquid temperature range: 0°C to 90°C

3. Operating pressure: Max. 10 kg/cm²

4. Inlet pressure: Max. 6 kg/cm²

5. Head: 50Hz : Up to 70M

1.4 Applications

TPH pumps are horizontal, multistage centrifugal pumps
for the pumping of clean, thin and non-explosive liquids,
not containing solid particles or fibres that may attack
the pump mechanically or chemically.

or toxic liquids.

2. Installation and piping

2.1 Installation site

2.1.1 For secure operation, please mount and bolt
the pump base to the foundation.

2.1.2 Select a dry and good ventilated site and
provide accessible space around the pump
for future maintenance and service.

2.1.3 Make sure the ambient temperature is
below 40°C(104°F) and the flowing liquid
temperature does not exceed 90°C(194°F) .

2.1.4 Do not operate the pump under explosive
environment.

2.1.5 Horizontal installation is recommended.
When it is installed in other positions, please

provide drain holes to allow drainage of the
pump.

2.1.6 Indoor: TO avoid your furniture damage, do
not install the pump on ceiling, carpet or any
place close to electrical appliance, and also
must provide drain hole.

2.1.7 Outdoor: When the pump is installed outside,
please provide a suitable cover to protect it
from weather and frost. Please do not allow
any foreign objects fall into the motor fan
cover.

2.2 Electrical connection

2.2.1

This mark located outside the connection
box is a warning for an electrical hazard.

2.2.2 The electrical connection should be carried
out in accordance with local regulations. The
operating voltage and frequency are marked
on the nameplate. Please make sure that
these data match with your job requirement.
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.

2.2.3 Motors must be connected to a motor­protective circuit breaker which can be
manually reset. Set the motor-protective
circuit breaker according to the rated current
of the motor. See nameplate.

2.2.4 Three phase motors must be connected to
a motor starter for protection of overload
and single phase running. Please be sure if
the direction of rotation is correct. For three
phase motor you can reverse the direction
of rotation by interchanging any two of
the incoming supply wires. Before your
first operation, please place a allen wrench
against the shaft at motor end and turn by
the direction of rotation to see if rotor spins
freely.

2.2.5 The position of the connection box is
adjustable. It can be turned either side before
the pump is installed. The preset position
from the factory is on the top of the motor.
To change the position of the connection
box, please remove the bolts on the motor
frame (4 bolts which are bolted into the
chamber) and turn the stator housing to the
required position. Replace the screws and
tighten securely.
