Page 7: Precaution For Installation / Piping
Precaution for installation / piping Installing the pump and piping properly makes a pump deliver prescribed performance. Improper piping may lead the pump damage, so install the pump adequately. 【Example to use】 Installation place/position The installation place is near the tank as much as possible and the liquid level is in the installation range. - Page 8 Piping instructions The suction pipe employs the end suction method, short and less bending. Do not allow areas where air is trapped in the suction pipe. It may cause an airlock (dry running). When a screen such as a strainer is installed at the suction inlet, periodically clean the screen. If it is clogged, it causes the pump’s performance and function failure.
