pump's made of cast iron and got the buna-n seals, that setup work alright for oil and gas applications?
Answer by: Customer Support on Feb 18, 2026, 3:51 PM
Cast iron construction holds up well in demanding oil and gas environments, and Buna-N is a solid seal choice for petroleum-based hydraulic fluids commonly used in that industry. This pump is specifically listed for oil and gas use alongside other heavy-duty applications like primary metal processing and die casting, so it fits right in that kind of service.
