Coolant Pumps
■Extensive product lineup
Immersion type
Floor type(Self-priming type)
For tank cleaning
Mechanical sealing type
※High efficiency due to no leakage
Non-seal (mechanical seal-less) type
※Not easily affected by chips, can be used for dirty coolants.
TERAL’ s original non-seal structure
allows coolant to flow from a narrow
clearance without using a seal between
the pump section and motor section.
Many advantages
that only non-seal pumps
can provide
1
No coolant leakage
or other problems.
※What is the non-seal structure?
This structure releases coolant by
depressurizing through a narrow clearance.
No mechanical seal is used.
Helps cut down
running costs.
2
No need for a safety
valve, escape piping,
or a three-way valve.
Helps cut down
initial costs.
3
Prevents
air accumulation.
Reduces initial trouble.
4
Capable of
serial running
A series of volute pumps
can generate up to
3.92MPa
(40kgf/cm2).
5
Not easily affected
by small quantity of liquid
or shut-off operation.
Build the pump system
you want.
6
Not easily
affected by chips
Can be used for
dirty coolants.

Notes 1. As the pump whose model number has a suffix L (with marked ★) has cabtyre leads, it does not conform to CE marking and its degree of protection is IP23.
2. The discharge rate and total head values were obtained in tests with a liquid viscosity of 1mm2/s (same as tap water at normal temperature). Note that the pumps cannot be used with water.
3. VKP□□J and VKP115A are bottom suction types.

■Features
①Mechanical seal-less structure
④Impellers designed for high-frequency operation
⑥Energy-saving operation by the inverter(flow rate adjusting, etc.) (10 to 60Hz)
Note: Resonance may occur arbitrarily when the unit is operated at variable speeds using the inverter.
Operate the unit avoiding the resonance points.
■Structure
Non-seal (mechanical seal-less) structure. Aluminum frame is used in the motor section and
stainless steel is used in the pump’s main unit. Special coupling is used for the connection.

■Features
①Mechanical seal-less structure
④Impellers designed for high-frequency operation
⑥Energy-saving operation by the inverter(flow rate adjusting, etc.) (10 to 60Hz)
Note: Resonance may occur arbitrarily when the unit is operated at variable speeds using the inverter.
Operate the unit avoiding the resonance points.
■Structure
Non-seal (mechanical seal-less) structure. Aluminum frame is used in the motor section and
stainless steel is used in the pump’s main unit. Special coupling is used for the connection.

Notes 1. As the pump whose model number has a suffix L (with marked ★) has cabtyre leads, it does not conform to CE marking and its degree of protection is IP23.
2. The discharge rate and total head values were obtained in tests with a liquid viscosity of 1mm2/s (same as tap water at normal temperature). Note that the pumps cannot be used with water.
3. If the pipe diameter (inlet and outlet) is different from the standard diameter, the maximum length of suction pipe is inversely proportional to the square of the pipe diameter.

Selection Guide
Coolant Pumps
The pump characteristics vary significantly with pipe routing. Head loss due to pipe length and fittings can
be greater than expected. Pipes should be as short as possible, and the number of bends such as elbows,
fittings and valves as few as possible when designing pipe routing.
Head loss is calculated as shown below.
Calculate the total head required to deliver
Piping resistance (head loss) Hf
Fig.1
50ℓ/min in Fig. 1.
Elbow
Actual head Ha: 2m
Elbow
Pipe dia. 1A (1B)
→ φ30mm I.D.
Elbow
Total head is given by Ht = Ha + Hf [m], where
Ha and Hf are actual head [m] and head loss
[m], respectively.
In Fig. 1, actual head Ha is 2m and head loss Hf
(※1) 0.79m. Total head Ht is therefore 2.79m
(Ha + Hf = 2 + 0.79m).
To deliver 50ℓ/min, a pump with total head of
2.79m or above is required (Fig. 2).
Water soluble liquids
Note: This is a calculation value. The actual pump
operating point varies significantly depending on the type
of liquids used, viscosity and piping.

V: Flow velocity [m/s]
d: Pipe I.D. [m]

Note: Loss coefficient of water-soluble liquids is assumed
0.03. Oil-based liquids have a much larger value.

※2 How to Obtain the Equivalent Horizontal Length
In Fig. 1,
Straight pipes: 1m + 1m + 1m = 3m
Elbows: 1.6m + 1.6m + 1.6m = 4.8m
Inflow: 1.1m
Outflow: 2.2m
Equivalent horizontal length L is therefore 3mm
+ 4.8m + 1.1m + 2.2m = 11.1m
Note: Equivalent horizontal length of elbows and other
components is shown in Table 1 as a guide.

Handing Precautions
Coolant Pumps
Item Type
Description
・Piping should be as short as possible and the number of bends
such as elbows, fittings and valves as few as possible. Use pipes of
a standard size. The discharge rate will decrease if the pipes are
thin or have many bends.
・Provide effective support for the pipes so as to prevent the pipe
weight from being directly applied to the pump.
・Do not forcibly screw the pipe into the pump. The fitting may be
destroyed.
・Prevent liquid or air leakage from the pipe thread joints by applying
seal tape or the like. Correctly apply the tape so as not to close off
the piping.
・Use a tank (oil tank) of a large capacity to the extent possible.

Installation

▲Standard installation
recommend installing an overflow unit of three or more steps and a filter.
・If water hammer is likely to occur, take preventive measures such as
installing a bypass after the pump outlet.
・If the fluid level is too low, air will be introduced to decrease the
discharge rate or the liquids may not be pumped. The fluid level
must not be lower than the recommended minimum fluid level
(Min. F.L.) shown in the Assembly Drawings. This level varies with
viscosity. For safety purposes, the actual fluid level should be
sufficiently high. On the other hand, the liquids will enter the motor
through drain holes if the fluid level is too high, resulting in motor
failure. The fluid level must not exceed the maximum fluid level
(Max. F.L.) shown in the Assembly Drawings.

・The pump shall be installed as close to the tank as possible so that
the suction pipe is short. The maximum length of the suction pipe
should be 0.7 m (0.6 m for VKN085A, VKN085H and VKN095H). If a
long suction pipe must be used, a check valve shall be installed in
the suction piping. Sealing tape shall be used for the pipe screw-in
position to prevent fluid and air leakage. Particularly, air leakage
from the suction hole should be avoided because it may result in
decreasing the flow rate or insufficient pumping performance.
・After installation, deaeration by priming is necessary because air is
stored in the pump chamber (shaded section in the figure below) at
initial start-up or start-up after a long interval. The air in the pump
chamber may result in some problems including poor suction or failure
to achieve pump performance (insufficient flow rate or pressure).
Further, if the pump is operated for a long time without suctioning the
fluid, mechanical seal damage or other damage may occur.
[How to Prime]
VKN Series
・Pour the liquid from the discharge side until air is completely eliminated from the pump chamber,
or until air no longer comes out of the tip of the suction pipe. Note that the priming liquids will
not completely enter the pump if height H2 from pump outlet to the priming liquid opening is
smaller than the length H1 of the suction pipe below the fluid level. In this case, install an air
vent for priming on the suction pipe or sufficiently increase the height of the priming liquid
opening.
LPS Series
・For priming, the liquid shall be supplied from the priming port of the pump discharge hole until
the liquid appears from the suction pipe.
・The VKN/VKP Series has 4 mounting holes (except some models).
Only one set of diagonally opposed holes is used for securing the
unit. The other is provided to allow for possible extended
applications. (One set is to the JEM and the other to the company
standard dimensions.)

How to prevent problems with
immersion-type pumps
Fluid leakage detection hole
(Models LPW and LHW)
If liquid comes out of this hole,
replace the shaft seal and deflector.
Escape hole
Regular escape piping recommended.
To prevent the problem of air accumulation, it is
recommended to create a path that releases air.
Deflector
In the case where the pump is elevated,
cut off the shaded sections.
Provide wide gaps. Otherwise, chips will build up on
these sections to inhibit discharging, which may result
in coolant entry into the motor.
Shaft seal

LPS40 Series
Deflector
Oil seal
Drain hole
Fluid may leak from the fluid
intrusion detection hole if the
drain path is clogged.
Fluid intrusion detection hole (LPS40)
LPS
Leakage from the fluid intrusion detection
hole indicates an abnormality with the
drain path. Fluid has most likely entered
the motor if this hole is clogged.
Siphon prevention hole
If the siphon prevention hole is clogged,
sufficient priming fluid will not remain in
the pump due to the siphoning phenomenon
after stopping the pump. If this happens,
suction may be impossible when the pump
is restarted.
Shaft seal (Sliding section)
Excessive abrasion on shaft seal (sliding section)
may result in an increase in leaking fluid, resulting
in leakage from the fluid intrusion detection hole.
Cleaning hole
If the siphon prevention hole is clogged,
inspection and cleaning shall be conducted
upon removing the plug.
Note: While the structure of LPS65 is different from that shown above, the same advice is applicable to the shaft seal (sliding section), drain hole, siphon prevention hole and cleaning hole.

Handing Precautions
Item
Description
General
Coolant Pumps
・Thoroughly read all instructions provided in the instruction manual before handling the unit (installation, transportation, maintenance,
inspection, etc.) and use the unit correctly. Familiarize yourself with the mechanisms of the unit, and safety and handling procedures
before using the unit. Like maintenance and inspection of the unit after start-up, proper handling after purchase of the unit and until
start of actual operation is indispensable in operating the unit to its full performance potential, preventing accidents and ensuring
satisfactory operation for many years to come.
・Do not work with live circuits. Work on the unit only after turning the main power off.
・Turn the main power switch off in the case of power failure.
・Immediately stop the unit and turn the main power switch off if an anomaly is detected.
・Securely connect the earth terminal to the ground.
・Piping and wiring of the unit should be performed according to the Technical Standard for Electric Facilities and Internal Wiring
Standards.
・Protective devices are not included in the unit. Installation of an overcurrent protective device is mandatory as specified in the Technical
Standard for Electric Facilities. We recommend installing other protective devices (e.g. ground-fault circuit interrupter) in addition to the
overcurrent protective device to prevent burnout of the unit.
・Provide sufficient dust- and drip-proof measures using connectors, glands, etc., so that cutting chips, coolant solutions or any other
foreign matter will not enter the terminal box through external wiring ports. Keep the grommets in place at the external wiring ports
that are not used.
・Electric current will increase and the motor will burn out if voltage drops significantly. The thermal relay can also trip.
・Do not use the unit in an explosive atmosphere.
・Never place flammable substances near the unit.
・Increased-safety and explosion-proof type coolant pumps cannot be manufactured.
・The unit may not be used for kerosene, gasoline or other volatile liquids.
・Never approach or touch the rotating components of the unit (external fan, impeller, etc.) during operation.
・Do not insert your fingers or objects into the openings of the unit (fan cover, pump inlet and outlet, drain hole, etc.).
・Never step on the unit.
・The unit can become very hot during operation. Never touch it with your hands or body.
・Clear the area around the unit to ensure free air ventilation.
・Install the unit in a place where the unit is easily maintained and inspected (avoid a confined area).
・Install the unit on a flat and level place. Make sure the unit will not rattle.
・The maximum allowable external vibration acceleration for the unit is about 4.9 to 6.9m/s2.
・Operation frequency may not exceed 60Hz when an inverter is used in drive. Resonance can occur arbitrarily depending on pump
installation conditions. Avoid using the unit at resonance-inducing frequencies.
・The motor service life will be reduced and risk of burnout will exist if the viscosity of the liquids in use is too high. Observe the limit of
the allowable viscosity [mm2/s] stated in the specifications for the unit. Viscosity can increase considerably when the temperature of the
liquid drops. Check the viscosity of the liquid for the lowest specified temperature of the liquid.
・The unit is designed for use with coolants such as grinding and cutting fluids. For the pumps incorporating mechanical seals
(VKA/VKC/VKH/VKN), the life of the mechanical seals will be considerably reduced if hard sludge such as grinding powder, abrasives
and diamond grains is present in the liquids. Install suitable filters (magnet or paper filter, etc.). The unit is not used for special liquids
(printing and acidic liquids). Contact us when using the unit for other special liquids (e.g. ceramic).
・Check the direction of rotation before connecting the unit to the customer’s system.
・For pumps provided with an air vent valve, open the valve slightly when starting up the unit and make sure that the liquids are
discharged from the valve. Firmly close the valve after checking.
・As this is a centrifugal pump, the flow rate can be freely adjusted by controlling the valve on the discharge side. The motor is not
overloaded when the valve is shut off. However, if you perform shut-off operation with a pump provided with mechanical seals, allow
a small flow rate quantity (0.1ℓ/min or more) to continually flow by, for example, installing a bypass.
・Repair, disassembly and modification of the unit must be performed by an expert.
・Modification of the unit by the customer relieves us of our responsibility for the product. We shall not be responsible for such
modification including the results thereof.
・Dispose of the unit, when necessary, as general industrial waste.
・We also manufacture units of different voltages in addition to the specifications mentioned in this catalog. Contact us for further details.
