Acceptance checks ---------------------------------------------------------

Please check the following when the coolant pump is delivered.

1) Check the type, output, voltage, frequency, etc. of the delivered pump in reference with the

nameplate to verify that the correct product has been delivered.

2) Check that the coolant pump has not been damaged during transport and that bolts are firmly

tightened. If any problems are found, please consult the dealer where you purchased the coolant

pump.

Specifications ----------------------------------------------------------------

Refer to the nameplate for the coolant pump's head, flow rate, frequency, voltage, current, etc.

Other specifications are described below.

1) Type

2) Fluid The Coolant Pump (standard product) is designed for use with coolant,

including grinding oil and cutting oil. However, since the life of the mechanical

seal might decrease, when the fluid contains large quantities of hard sludge (e.g.

abrasive powder, abrasive grain, diamond grain, etc.), install the filter (e.g.

magnet filter, paper filter, etc.). In addition, the pump cannot be used with fresh

water or special fluid, such as printing fluid, acids. When you want to use other

special fluid (e.g. ceramic etc.), inquire of your dealer or our sales branches.

3) Fluid temperature -20 to 40°C (without freezing)

4) Fluid viscosity Using high viscosity fluids will shorten the life of the motor and may cause the

motor to burn out. Be sure to use the fluids with the viscosity within the limit in

the table below. Note that the viscosity may greatly increase as the fluid

temperature decreases. Check the viscosity when the temperature of the fluid

in use is lowest.

Notes

1. The current indicated on the nameplate is when the maximum load is applied

at the limit of viscosity (operated with valve open).

2. The rated head and flow rate indicated on the nameplate is when the viscosity

is 1 mm2/s.

5) Installation location Always use the pump indoors in a location free of flammable gas or vapor and at

an altitude of 1,000 m or less.

6) Ambient temperature-20 to 40°C

Installation --------------------------------------------------------------------

1) Select a well ventilated location with little dust and humidity. Do not install the pump where fluid

splashes onto the motor.

2) Install the pump so that cooling air for the motor can be taken in.

3) Install the pump on a flat surface to prevent any clearance.

4) Select a location where servicing can be performed easily. (Secure sufficient space.)

5) The pump is resistant to externally applied vibration acceleration up to approximately 4.9 to 6.9m/s2.

6) Because the pump section of the VKA type coolant pump is installed in a tank, an mounting hole

larger than the outer diameter of the pump needs to be made. See the outline drawing.

7) Because the suction port is on the bottom of the pump in the pump section of the VKA type coolant

pump, secure at least 5 mm between the bottom of the tank and the suction port. Secure the largest

separation possible to prevent the strainer being clogged with cutting chips and dust.

8) The pump is painted. However, if you want to coat the pump with another color, lightly sandpaper the

pump surface to improve paint sealability.

Piping --------------------------------------------------------------------------

1) Make the piping as short as possible with the minimum number of elbow bends, joints, valves. Use

standard sized pipes. Thin pipes, or those with an excessive number of bends, may reduce the

amount of discharge.

2) Support pipes to prevent the weight of the pipes being loaded directly onto the pump.

3) Do not forcibly screw the pipes into the pump. Doing so may damage the joints.

4) Use seal tape, fluid packing, etc. for threaded sections to prevent fluid and air leaks. Wind the seal

tape correctly so that the port of the pipe is not blocked.

5) Use the largest fluid tank possible.

* The recommended tank capacity is at least three times of discharge amount per minute.

Using a tank with excessively small capacity may cause problems, such as the fluid temperature

increasing, the strainer clogging with cutting chips faster than usual, reduction in the amount of

discharge due to generation of bubbles, etc.

* Put the fluid quietly so that air should not mix when you pour the fluid into the tank.

6) Prevent cutting chips and dust from entering the pump.

* We recommend that you pass the cutting fluid through an overflow section and filter at least three

times. Cutting chips entering the pump may damage the mechanical seal. Be extremely careful.

Take appropriate preventive measures to prevent water hammer (e.g. install an accumulator etc.).

(Reference data)

- Pump discharge port (outlet) size: PS3/4 (for piping)

- Pump mounting bolt: M6 (4 locatios)

Wiring --------------------------------------------------------------------------

1) Wiring must conform to the Electric Facility Technical Standard authorized by the government and

the Interior Wiring Code of the electric power company.

2) For standard voltage products, see the drawing on

the right and connect the motor terminals to the

power supply terminals correctly.

* When the number of terminals is 4 or more, refer to the connection nameplate inside the terminal

box.

3) Ground the wire in case of earth-leakage.

4) We recommended that you use a thermal overload relay to protect the motor from overload and burn

out.

5) You can change the position of the terminal box relative to the discharge port of the pump in

90-degree increments by shifting the motor frame. (excluding the right above the discharge port)

Change the position of the terminal box depending on the installation location.

6) When using connectors, glands, etc., take sufficient precautions to prevent cutting chips, coolant, etc.

from entering the terminal box through the lead-in port. Do not remove the grommet from the lead-in

ports that are not used.

7) Note that the electric current will increase and the motor may be burnt out when the voltage drop is

remarkable. Or else, the thermal overload relay may trip.

Operation ---------------------------------------------------------------------

1. Before starting operation

Because a mechanical seal is used for the shaft seal of the pump section of the VKA type coolant

pump, do not operate the pump without fluid. Doing so may damage the mechanical seal.

Check that the fluid is above the specified level, and confirm that the discharge port is open.

2. When starting operation (When conducting test run)

1) Check that the pump rotates counterclockwise (to the left) when viewed from the top.

2) Check that there are no problems, such as overcurrent, vibration, or noise. If any problem is

identified, see the "Troubleshooting" section for appropriate measures.

3. Operation

1) An involute pump is used for the Coolant Pump, meaning the flow rate can be adjusted by

opening and closing the valve on the discharge side.

Although the motor is not overloaded with the valve fully closed, the temperature of the fluid in

the pump will rise, which may damage the mechanical seal. Do not operate the pump with

the valve fully closed. If unavoidable, provide a bypass route to maintain a minimum flaw rate

(0.1 L/min or more) or stop the motor when not operating the pump. When the temperature of

the fluid rises excessively, the service life of the motor and pump parts may be shortened.

2) Depending on the viscosity of the fluid, air may be taken in if the fluid level is too low, lowering

the amount of discharge or preventing the fluid being pumped. Make the fluid level higher

than "Minimum fluid level". Note that the minimum fluid level differs depending on the

viscosity of the fluid. For safety, keep the fluid level as high as possible.

3) If power failure occurs during operation, turn the power switch off.

Maintenance -----------------------------------------------------------------

1. Daily checks

Check for abnormal vibration or sound when starting operation and during operation.

2. Periodic checks

1) Remove dust, oil, etc. on the external surface of the coolant pump.

2) Accumulation of cutting chips in the tank may cause pump failure. Clean the inside of the

tank periodically.

3) Check that the pump's strainer is not clogged with cutting chips. Clean the strainer when it is

clogged with cutting chips.

3. Maintenance of bearing

Using shielded type grease-sealed bearings reduces the bulk of maintenance work including

replenishing grease. Exchange the bearing when an abnormal sound or vibration occurs from the

bearing.

4. Maintenance of mechanical seal

Although the mechanical seal can withstand long-term use in normal operation, operation without

fluid or with a large amount of slurry may damage the mechanical seal. When you find such

problems as fluid leaking from the drain hole or abnormal sound from the mechanical seal,

replace the mechanical seal with a new one.

5. Maintenance of oil seal

Pumps with an external fan have an oil seal to prevent fluid entering in the bearing section.

Replace the oil seal with a new one when replacing the bearing.

* Parts replacement

The service life of parts is determined by the type, atmospheric conditions, and working

conditions. We recommend that you replace parts referring to the table below:

Replacement frequency of consumable parts
