transfer pumpを設置するとのことですが、弊社は使った経験が無く、その効果は不確かです。
逆洗ラインにbooster pumpを設置する方が実績があるため、それを推奨します。
pumpの接続はinlet sideに、とのことですが、Outlet sideを推奨します。
なぜなら逆洗は、Outlet sideからInlet sideへの流れなので、差圧が極度に高い場合は、
Inlet sideから増圧してもOutlet sideの圧力が上がらず逆洗の流れが発生し難いためです。

I got to know the installation of the transfer pump. However, we never experienced utilising it, and we are not sure of the effectiveness. We have a good result of placing a booster pump at the back washing line, therefore, we recommend it.
You might say the connection of the pump to "inlet side", we prefer the outlet side.
Because, for the backwashing, it is a flow from the outlet side to the inlet side, the difference in pressure is extremely high, if you increase the pressure from the inlet side, the pressure from the outlet side will not increase, and there might be a possibility to backflow.

I hear that you are going to install transfer pump, but our company does not have an experience to handle it and their effect is not clear.
We recommend to install booster pump for back washing line because there is better result.
And you request to connect pump for inlet side but we would like to recommend for outlet side.
Because back washing flow is from outlet side to inlet side, so if there is an extremely high pressure difference, it will be difficult to make flow of back washing to make high pressure for outlet side even if we increase pressure from inlet side.

You mentioned installing a transfer pump, but we have no experience with it and are not sure of its effectiveness.
We recommend using a booster pump in the backwash line, as it is more proven.
You mentioned that the pump should be connected to the inlet side, but we recommend the outlet side.
This is because backwash is a flow from the Outlet side to the Inlet side and if the differential pressure is extremely high, it is difficult to generate backwashing flow because The pressure in the Outlet side does not rise even if the pressure is increased from the Inlet side.
