What is the capacity of this pump?

[BertZegers]

I recently bought a Case 1816C skidsteer. The pump for the cylinders is noisy, and I think the replacement is DFE080 (9-12390) Surplus center.

The question I have is what is the displacement of the old pump?
REXROTH 05098 S12SX50AK55R



I read somewhere that it is 8 Gpm at 1100 PSI at 3600 RPM, but want to be sure.

I could order the pump from the dealer as well, but big $$$$$$$$$$$ in Canada.
I am hoping to get the info from this forum, and order an after market (from US). That is why I ask.

Ask them what the output is....

according to my old Rexroth literature that should be 0.58 cubic inch per rev, right hand rotation, with side ports but the X in the model code indicates a non-standard option so not 100 percent positive on the displacement.

Since you're going to replace the pump anyway, you could just open the pump to get the measurements needed for this calculator on Surplus center: Surplus Center

oldnslo thank you, that helps.

0.58 ci/rev works out to 9.0gpm without losses. With typical gear pump efficiency and some belt slip you would be right at 8gpm. ISZ
