• Feature 6: Standard ¾″ hose‑barb discharge connection; optional adapters and nozzles available

While many drum‑pump systems sacrifice portability for flow rate or torque, the Thompson Econo Air‑Motor Pump 8EP55P delivers both. Its ½ HP pneumatic motor uniquely combines variable RPM (300–11,000) with 27 CFM air consumption at 40 PSI, offering controlled, adjustable pumping speed suitable for delicate or aggressive fluids. The muffler attenuates noise, improving operator comfort in workshop or plant environments.

The corrosion-resistant pump tube—typically constructed from stainless steel or chemically inert materials—is engineered for durability, safeguarding against degradation when pumping weak acids, alkaline solutions, or Diesel Exhaust Fluid, which can be harsh on standard metals. With a 40″ length as standard, the pump reaches most 55‑gal drums easily, while 27″ or 48″ tubes are offered to adapt to shorter or taller container profiles.

Despite its modest size, the pump delivers up to 17 GPM and can maintain 20 ft of head—enough to reach elevated outlets or fill drums on platforms. It handles fluids up to 300 centipoise viscosity and a specific gravity of 1.2, covering many industrial liquids from cleaning agents to lubrication fluids. The standard ¾″ hose barb discharge simplifies hose connection and lets you pair it with hoses of various lengths or nozzle types.

Installing or removing the pump from a drum is straightforward, and optional bung adapters let you adapt to irregular drum fittings. Though the nozzle and adapter are sold separately, they integrate easily with the base pump. Overall, the 8EP55P is purpose‑built for shops, service trucks, chemical transfer stations, plating facilities, or any setting requiring safe, efficient fluid dispensing from drums. Low maintenance, affordable spare parts, and Thompson Pumps’ reputation for quality make it a smart long-term investment.
