What does this mean on Booster pump?

Just bought a booster pump and it says on the pump "inlet pressure: 30psi"

Does that mean it requires an inlet pressure of 30psi or that 30psi is the maximum. 

Anyone know?

I don't know but it mentions 70 psi beneath it. Why would they mention 70 psi if the maximum it could take is 30 psi? Maybe contact the manufacturer?

Unfortunately I bought it off eBay and have Googled it but not been able to find the manufacturer or spec sheet/manual.

I'll just have to try it and see I suppose.

It needs 30 psi from tap to work looking at it. Never heard of that before. With an R/O system depending on membrane size you will probably get around 300/400 ml a minute pure
