About Digital Rights Management

IMPORTANT UPDATE June 2025

HI publications (Standards, Guidebooks, and Guidelines) utilize digital rights management (DRM) through partnership with Vitrium.  Access to a document after purchase will require the customer to sign into their pumps.org account. The customer can login and access their purchase(s) across 3 devices including a DRM protected download. This DRM protected download will require PDF reading software such as Acrobat Reader.
