Please read this installation and
operating instructions carefully
before beginning installation and
operation.

1. Application

1.1

The TPK 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. Operating Limits

1. Liquid Temperature:+0°C~+90°C

2. Ambient Temperature: Max.+40°C

3. Enclosure Class: IP54

4. Discharge Pressure: Max.10kg/cm²

5. Submerged depth :Min. 40mm

6. Stainer Diameter: Ø2mm

7. Particle Size: 2mm

8. Liquids(maximum content of solid

particles in suspension 50g/m³)

9. Kinematical Viscosity: 32 cst (mm²/s)

10. Head: 50Hz : Up to 70M

60Hz : Up to 100M

4. Installation

The motor surface temperature
is extremely high. It must be
mounted in the save place to
avoid accidental touch.

4.1. Mounting Position

The pump must be mounted vertically.
Installation is simply done by inserting the
pump into the hole on the tank top, and xed
by four bolts in mounting flange. Flange
dimensions are shown in Fig 1.

4.2 Submerged Depth

To avoid dry running and damage the
pump during operating, the minimum
pump submerged depth is 40mm, as shown
in Fig. 2. 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 connection.
