Salamander pump size

[steq184]

Have at the moment an electric shower but am changing to a power shower.
Am about to purchase a pump, am looking to get the Salamander CT75 2.1bar pump.
I have been advised that my system is a fully pumped s plan system.
Would this pump be man enough?
This is the only shower in the house.

depends on shower, run of pipework etc

Well the shower is the 2 outlet type, 9" rose above head and small head hand held rose to side.
From hot water cylinder tank in airing cupboard to the shower would be around a 20 foot pipe run.

is the pipework going up and over the loft ?

Yes, the existing electric shower that we are changing has a good water pressure although I know that is only from the cold feed whilst the power shower would also have a hot feedm
