Booster pump pressure issue

Hi guys, I know someone's going to know the answer to this, nothing on the forum that I have managed to find. 

I'm running a 4040 with an axeon hf5 membrane, booster pump is a brand new wortex jx80.. Can only seem to build up 60 psi and that's when the waste is virtually closed (don't worry only did this for a few seconds then opened up full throttle again)

Anway is the too small for the membrane, or do I need a pressure building valve or tank, thanks for the help ?

Is your question is the pressure too small?

if so

hf5 will run as low as 30psi in real world. Ran one for 3 years on 37-40psi down to 13ppm from 300. 
And was slow with pre filter filter changes.

hi omega, thanks for the reply. really want it to run at its suggested minimum pressure of 80psi, just cant get it up there using my usual method of balancing the waste output, thanks

Sounds like the pump is too small. How many litres a minute does it do.

The wortex jx80 says it does 50l/min but a max of 38m head (125ft)  which is about 55psi. So looks like it's not man enough.

But don't take my word for it as I may have the calcs wrong?

Have had a look at the spec pressure is too low.

The next thing you have to do is build the pond. ?
