Actually, it could be used in an open center system without any alteration whatsoever. That pump by virtue of it's design is normally 'in stroke' and only goes out of stroke when the system pressure rises sufficiently that it acts against the stroke piston to destroke the pump. A spring puts the pump in stroke. So.... if one wanted to run it on open or tandem center for some obscure reason all they would need to do is funnel the entirety of pump flow through said OC valve and return oil through a cooler to keep the whole mess cool because it's probably going to get hot. I don't know off hand what charge pressure it would require but I suspect it's more than one atmosphere... so you'd still need a charge pump. If one wants an open center system it's a lot easier to just run a commercial gear pump and be done of it.
