Question by: Cody P on Nov 30, 2025, 6:09 PM
pump's made of cast iron and got buna-n seals -- would it hold up running hydraulic fluid in a die casting setup day in and day out?
Answer by: Customer Support on Dec 2, 2025, 5:44 PM
Cast iron housing handles the heat and mechanical stress that die casting environments throw at it pretty well. Buna-N seals are a solid match for standard hydraulic fluids, so you're not going to have compatibility problems there. Die casting is actually one of the listed applications for this pump, so it's built with exactly that kind of demanding, high-cycle use in mind.

Reckon this'll hold up okay in a plastics plant, what with all the cycling and whatnot?
Answer by: Customer Support on Oct 22, 2025, 6:29 AM
It's built with a cast iron housing, so it's durable enough for high-cycle industrial jobs like you'd find in plastics machinery.
