Diahman
Pump
Air-operated double diaphragm pumps engineered for demanding oilfield, chemical, and industrial fluid transfer applications.
Built for the
Toughest Jobs
The Diahman Pump is an air-operated double diaphragm (AODD) pump designed for reliable, continuous fluid transfer in oilfield, chemical, and industrial environments. Powered entirely by compressed air, it operates safely in hazardous and classified locations where electrical equipment is not permitted.
Its self-priming design and ability to handle solids, slurries, and high-viscosity fluids make it a go-to solution for crude oil transfer, produced water handling, chemical injection, and tank stripping operations across the Permian Basin, Eagle Ford, and throughout Mexico.
Vala Energy Resources is an authorized representative and distributor of Diahman pumps in Texas and Mexico. We provide local support, technical guidance, and competitive pricing for all pump configurations and replacement parts.
