DOPAG drum pumps are chop check pumps. They feed single component materials such as adhesives, sealing compounds, polyurethane, silicone etc. with viscosities up to 5.0 million mPa s directly from original containers.
DOPAG drum pumps are particularly useful as central material supply systems as well as being able to supply single stations. DOPAG drum pumps are manufactured as modular, robust, fail-safe, and maintenance friendly.
Product Features
Double acting, fast change-over air motor
Twin ram pump elevator
1 or 2-hand operation
Simple venting during container change
Chemical resistant seals
Hard chrome plated pistons
Adjustable packing
Hard tefl on seal kit
Flow rate up to 6 litres/minute
Pressure ratio up to 75:1
The integrated control unit ensures that the pump does not draw in air when the drum is empty. When the minimum level is reached the pump will shut down automatically. An audible alarm is emitted when the drum becomes empty.
External valves
The drum pump P200 can be supplied with external valves.
This new design offers the advantage of being able to carry out service and maintenance work on the pump without having to drain the system.
Wetted parts made of stainless steel or with specific surface treatment
Available in economy version for use with grease and oils.
Bung-mounted pump with cover plate
When processing low viscosity materials, a follower plate is not necessary for priming purposes.
The cover plate is used only as a protection against contamination of the medium to be fed.
Drum pump with follower plate
A drum pump with a follower plate is used for processing materials to high-viscosity media. The follower plate is made of aluminium, steel or cast iron.
The follower plate is manufactured with elastomer wipers for efficiently wiping the inside walls of the drum clean during use. The wipers adjust to the diameter of the container.

DOPAG has completely reengineered its product range inthe area of drum pumps suiting the needs of its customers specifically having grease application in mind. The DOPAG lubriLine drum pumps are featuring double acting ball valve or chop check pumps. They feed single component media such as greases and oils from NLGI0 to NLGI3 directly and clean from original containers. DOPAG drum pumps have prooved themselves useful as central material supply systems as well as supplying single stations. DOPAG drum pumps are manufactured as modular, robust and fail-safe, as well as remarkably service and maintenance friendly.
