Thanks for all of the posts. I have a question about the 28 GPM pump that Northern sells. According to their catalog, it has a 1-1/4" inlet and a 1" outlet. I looked at the Barnes Hldex website, though, and it says that this pump has a 1" inlet and 3/4" outlet. I emailed a guy on eBay who was selling one and he said that it has the Northern specs. Can you order different ports from the factory?
On a more practicle level, I want to use a valve with a 3/4" inlet. If the pump has a 1" outlet, where should I make the step-down to 3/4"? I'm thinking that I should run a 1" hose all the way to the valve and then just have a reducer coupling at the valve itself. There has been a lot of discussion about spped, in feet per second, of fluid in hydrualic lines. I think that this will reduce the speed of the oil, while maintaining the same flow, whereas reducing the hose to 3/4" at the pump would make the oil flow at a faster linear rate, at the same volume, making the oil hotter. Any suggestiosn would be appreciated. Thanks a lot
