140 Type (25 x 1, 38 x 1, 50 x 1) Divorced Pump Unit for Pails SR140PWAL-F · T series
Air-powered pressurized lift allows for stable transfer of high-viscosity materials.
The lift is raised and lowered by operating a valve. The airflow function makes it easy to remove the pump and inductor plate when switching pails.
・Model Change of SR140PWAL Series & New Inductor Plate (2026-06-17)
【Compatible Containers and Inductor Plates】
*This option is intended to be installed on units after the specification change. If you are considering installing it on a unit before the specification change (old model), please contact your nearest Yamada sales office in advance.
【Compatible Materials *】 Grease NLGI #0~3, Adhesives
*A note concerning materials. This applies to all high-viscosity products.
・Cannot be used with materials that contain food or slurry.
・The applicable range of NLGI No. (grease consistency) is provided as a rough approximation only.
・It may be impossible to use the product with some greases depending on their properties, even if they are within the scope of application for the product.

| The wide seal allowance of the packing allows it to be used for containers of varying inner diameter dimensions, such as tapered cans. A perforated metal plate attached to the bottom of the inductor plate minimizes the amount of material remaining in the pail. This allows material to be used without waste until the very end. | The high sealing property of the packing makes it suitable for extremely high viscosity materials that require lift pressurization. |
