3.5 Piping
3.5.1 Drain piping
- For piping, see the table below.
- Be sure that the pipe end is submerged in fluid.
- Do not join the drain pipe to other return lines. Run it independently.
Table 3.5a Drain Pipe Size
Even when the condition above is met, install the piping in such a way that the steady state pressure
in the housing is 0.1 MPa or less.
3.5.2 Suction piping
- For suction piping, use pipes of the following sizes.
Table 3.5b Suction Pipe Size
- Position the suction port 1 m or less above the fluid level.
- When installing the pump in a position higher than the fluid level, avoid placing the suction pipe
and filter at a position higher than the pump port to prevent air accumulation in the suction line.
- Keep the suction pressure at the pump inlet between - 16.7 kPa and + 50 kPa.
When the suction pressure exceeds the prescribed value, abnormal noise/vibration may occur.
