Double pump from Leimbach

[egronvold]

Not sure if you would call it twin or double pump (or something else ), but it's nothing I've seen before.

Very interesting. In the 1:1 world, dual variable piston pumps allow similar performance when using multiple functions at once. I think this a good approach for improved speeds and minimal space requirement.

Somewhere I have some diagram's, of older 1:1 excavators with a 2 pump system. I can post if there is any interest.

Thanks for the heads up. The 12V version might just do the 2 blade lift-rams and the 4-barrel ripper on my dozer build.
