Powder Transfer Diaphragm Pumps

The Yamada Powder Transfer Pumps were specifically designed to move bulk solids more effectively throughout your process. They are a cost effective replacement for Augers and Conveyors and eliminate unsafe and labor intensive means of moving bulk powders. These heavy duty pumps consistently transfer fine-grained (1 OOum or finer), low bulk density dry powders in a dust-free operation. v ^ Yamada offers a base unit specifically for light / powders, which include the following %^1T standard features. • Conveying distance depends upon the micron size and the bulk density of the powder. For example, fumed silica can be conveyed a maximum of 150 feet (45m). Flour can be conveyed a maximum of 40 feet (12M). Refer to the Yamada "Pumpable Powders" data sheetfbr specific materials. • Powder must be 150 mesh(106 micron)or smaller size particle / powder and dry. The Pump will not pump crystals or flakes and the bulk density should be less than 50lbs/cubic feet.(0.8kg/liter) The higher the bulk density, the shorter the conveying distance and the lower the flow rate. • The Pump can be located a maximum of 15feet(4.5M) above powder source. • Yamada recommends aeration /fluidization of the powder a minimum of 10 to 15 seconds prior to starting the pump- premature diaphragm, center shaft, and center disk failure • PTFE check balls are recommend for sticky powders. • Yamada recommends regulating compressed air to Activated Carbon Acrylic Resins Aluminum Oxide Carbon Black Cereal Flours Clay Powder Diatomaceous Earth Expanded Mica Fire - extinguishing Fumed Silica Ground Limestone Micro Dolomite Filter Powder Coatings Powdered Plastics Powdered Rock Quartz Powder Salicylic Acid - Apparent specific gravity is 0.5 or less - Angle of respose is 30 degree or less - Powder must be completely dry - Powder must have large fluidity The performance data for powder transfer is highly dependent upon the material being pumped and the application. A trial of the pump in the actual use environment is recommended to verify the actual performance capabilities for
