Foundation preparation (before pump installation)
1.
The area for anchoring the pump should be greater than the area of the pump base. If the
anchoring area is too small, the base may be destroyed due to the concentrated load on it.
2.
If pump operation is to be subject to vibration (resonation with the piping, for example),
provide an expansion joint between the pump and the piping. Otherwise, the piping, gauge, etc.,
may be damaged.
3. Installation advice
• Use anchor bolts to fasten the pump base firmly.
• Install the pump horizontally.
• Sufficient space is required to allow cool air from the motor fan to circulate.
• Allow ample space around the pump for easy and efficient maintenance work.

Load of piping for LK-N
When plumbing the pump, support the piping and use an expansion joint so as not to apply a load
onto the pump discharge/suction ports.
General precautions
1.
All piping should be supported independently so that unnecessary weight and vibration are not
transmitted directly to the pump. Expansion joint is recommended to avoid damaging the pump
head especially.
2.
The best piping arrangement for minimum pressure loss is achieved with straight runs and full
bore piping containing as few bends and fittings as possible.
