Relocating Air/Hydraulic Pump Question

[Kevin Means]

We are relocating some components to make room for our subframe and habitat. Two of those components are the hydraulic manifold and the air/hydraulic pump. (We're thinking about replacing the pump with a 12 volt pump, but the OEM pump we have was recently rebuilt and works well.) The manifold will be about two feet higher than it's normal position and will be mounted on the black bracket shown in the picture. We are planning to mount the pump in the location shown in the other picture, but it will be about 3" higher than what is shown in the picture.

When the two components are relocated to their new positions, they will be pretty much level with each other. In their factory installed positions, the pump is much higher than the manifold I know it's a sealed system, but I'm no hydraulics expert, so I was wondering if there is any problem with the relative heights of those hydraulic components being level vs. one higher than the other. Thanks

no problem that i can see. in the end fluid does not flow unless cylinders are moving and vis-versa...

The problem with electrics is finding one small enough to properly feed this tiny system. most all you will find are grossly oversized. since this system is flow restricted and has flow related safeties, it can only accept so much flow(1/3-1/2GPM MAX). Electrics know one thing: Make rated flow? they will do this regardless of whether the system can accept it or not. if the system can accept more, the electric HPU will build whatever pressure is needed to move the load and then flow at full rated flow.

If the system cannot accept the flow the Electric HPU will still flow its rated amount by running to maximum pressure, opening and flowing most of the fluid thru the safety relief. Because of this the pump, wiring and battery will always run at max load requiring larger wires and battery capacity than the work really needs.

Closest i came to being appropriately sized was a marine hydraulic trim pump, used to tilt and lift outboard motors and actuate trim tabs...
