Drum Pumps

Clean feeding directly from original containers DOPAG drum pumps have proved themselves to be particularly useful as central material supply systems as well as being able to supply single stations. They feed viscous materials such as grease, adhesives and sealants or the base components of silicone, polyurethane and epoxy resin directly from original containers. Pumps for Adhesives and Sealants The DOPAG range of adhesive pumps is suitable for feeding all types of adhesives, whether light or heavy viscosity. Adhesive pumps are available for feeding light viscosity adhesives directly from bung type drums, whilst ram mounted adhesive pumps fitted with follower plates can be used with higher viscosity non-flowable adhesives. Adhesive pumps for light, flowable adhesives can be lowered into the drum via the bung hole of the drum, either manually or by means of a pneumatic elevator. Each adhesive pump for higher viscosity products is mounted onto a twin post ram arrangement and is fitted with a follower plate that fits snugly inside the material drum, making certain that the adhesive cannot become contaminated during use. The follower plate also has the effect of wiping the sides of the drum clean that leads to minimal waste. Pumps for Lubricants The range of DOPAG grease pumps are designed to feed all types of greases from open topped containers of between one litre and 200 litres in capacity, cleanly and directly from the original containers. Each grease pump is mounted onto a twin post ram arrangement and is fitted with a follower plate that fits snugly inside the material drum, making certain that the grease cannot become contaminated during use. The follower plate also has the effect of wiping the sides of the drum clean that leads to minimal waste grease. DOPAG grease pumps have proved themselves particularly useful as central material supply for multiple grease metering systems as well as being able to supply single stations. The grease pumps may be arranged in pairs with an automatic changeover system to ensure that production is not lost when a drum of grease becomes exhausted.

PRODUCTS

  • 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 Level Monitoring 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. Options 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.
