Drum pumps help transfer liquids from drums in a simple and safe way. A drum pump moves fluid from the bottom of a drum and delivers it through a hose with clean and controlled flow. This page explains how drum pumps work and presents electric and pneumatic technologies trusted across many ARO customers and industries.

An electric drum pump includes a motor, a pump tube, and a discharge hose. The tube extends into the drum and reaches near the bottom to collect fluid. The motor drives an impeller that creates suction and moves liquid upward through the tube. The liquid exits through the hose with smooth and controlled discharge.
A pneumatic drum pump operates using compressed air to power an internal motor, creating strong and consistent suction to draw fluid from the bottom of the drum. The liquid is then transferred through a dip tube and discharged via a hose with smooth, controlled flow—without the risk of overheating or sparking. Ideal for demanding industrial environments, this technology ensures safe, efficient transfer and is compatible with a wide range of fluids, including chemicals and flammable liquids.
Selecting the right impeller type is a key factor in ensuring transfer efficiency, minimizing shear stress on the fluid, and optimizing pump performance across different industrial conditions.
Electric drum pumps deliver steady flow, strong speed control, and simple setup. They support many impeller types and offer high flow for long tasks. Their modular design also helps reduce downtime.
