3. Installation
Check if installation doesn't adversely affect facility, surrounding equipment and the pump.
Install the pump according to the following instructions to ensure the optimum performance, safety
and service.
■ Installation location
• Keep a wide working space for convenience in installation and maintenance.
• Select a flat & rigid floor/foundation where is free from vibration and contortion.
• Select a location free from flood.
• Optimize layout for convenience in carrying in and out.
• Install a chemical protective barrier for unexpected chemical outflow.
■ Pump position
Install the pump according to the following instructions.
• Install the pump as close to a supply tank and liquid level as possible.
• The maximum suction lift is 4m, however, try to keep the lowest suction lift.
NOTE: The maximum suction lift varies with liquid characteristics, specific gravity, liquid
temperature and suction line length. Contact us for detail.
See "4. Pipework" for more information on pipework. Pipework section describes a
basic layout and precautions.
■ Foundation work
• Use a level to check if a foundation is flat. Securely fix the pump by foundation bolts.
• Insert a shim if there is a gap between the base bottom and foundation surface.
• The foundation should be larger than a pump base footprint.
• See the following drawing for mounting the pump base on a foundation.
<Foundation work procedure>
a. Place the pump onto a foundation. Insert liners
between the base bottom and foundation surface
to keep a mortar injection space.
b. Screw nuts in foundation bolts until three threads
appear after the nuts. And then insert the bolts in
threaded holes.
c. Place a level on the pump base to see flatness.
Inject cement mortar into the threaded holes and
wait for three days until it has hardened.
d. Remove the liners after cement mortar has hard-
ened and check flatness again. Then tighten the
nuts on the foundation bolts. If there is a gap
insert a shim.

■ Suction line
1. Suction pipe bore should be equal to the pump inlet bore (25A or 40A)
If a suction pipe bore is larger than a pump inlet bore, air volume in suction line becomes so large that the
pump can not make self-priming.
2. Suction line length should be within 4.7m in total (Horizontal and vertical pipe line)
Suction line length is the entire length from the pump inlet to the lowest pipe end, including horizontal
line. If suction line is longer than 4.7m, air volume becomes large in the line. This prevents the pump from
sucking liquid even if the suction lift is 4m or less (the maximum suction lift is 4m). Also, If a supply tank is
too small, a liquid level can fluctuate significantly.
3. End of suction line
• The end of suction line should be at least 500mm below a liquid level for the prevention of air ingress.
• The distance from the lowest pipe end to a tank bottom should be 1.5 times larger than a suction pipe bore.
• Provide a screen in a supply tank for the prevention of foreign matter interfusion (Clean the screen periodically.).
4. A suction gate valve should be installed
In flooded suction, install a gate valve on suction line for easier overhaul & inspection.
5. Make sure joints on suction line are secure and air doesn't come in. Try to reduce the number of joints. If air
enters suction line, liquid may not be pumped or the pump may break at its worst.
Installation
4. Pipework
Foreign matters such as sand and scale may enter pipework while you are working. They may cause
fatal damage to the pump. Be sure to blow them out before operation. Also, do not apply adhesive
too much or leave a screw or nut.
If pipework directory weigh on the pump, plastic parts may be deformed. Be sure to install pipe sup-
ports.

6. Do not make an arched line in order to prevent air from being trapped. A suction line right before the pump
inlet should be laid on a rising gradient of 1/100 toward the pump.
■ Discharge line
1. Discharge pipe bore is related to pipe resistance
Pipe resistance increases if a discharge pipe bore is too narrow, so that an intended flow can not be
obtained. The increment of pipe resistance also affects self-priming performance when degassing is inter-
rupted. Install a 500mm straight pipe right after the pump outlet.
2. A discharge gate valve should be installed
Install a gate valve on discharge line not only for adjusting a discharge flow but also smooth operation,
inspection and maintenance. Make sure that discharge or air vent line is open during self-priming opera-
tion.
3. A check valve should be installed
When selecting a check valve, check the pressure limit in relation to the influence of water hammer or
back flow onto the pump.
• Discharge line is too long.
• Actual discharge head (Static discharge head plus Discharge pipe resistance) is more than 15m.
• The end of discharge line is 9m higher than a liquid level.
• Several pumps are running in parallel.
4. Air vent line should be arranged in the following cases
• Horizontal discharge line is 10m or more.
• Air vent line is required when a check valve is installed. Otherwise self-priming can not be performed.
• Air vent line is required when discharge line is not at atmospheric pressure. Otherwise self-priming can
not be performed.
5. A pressure gauge should be installed
Install a pressure gauge on discharge line for monitoring operation condition.
