pto pump

I have a pto ump on my truck for end dump trailer,got one line from tank to pump and return line from pump to tank,and from pump one line for trailer.Pump puts out 2000 psi.would like to also like to use it for a detach lowbed is that enough pressure,my machines weigh around 45,000 pds.And how can a person plum another line in for the lowbed,but also use it for dump trailer when needed.
