The Cement Feeding Screw Pump is a heavy-duty dry material feed pump. It is designed to feed dry powder/cement/ fly ash, material into a pneumatic conveying line. The screw pump works where other dilute phase feeders have failed due to problems like high pressure , fine material dust. Unlike rotary airlocks, which require tight clearances to seal against the conveying air, the screw pump design utilizes conveyed material to form a seal. An integral gate prevents blow-back when priming or running empty.

The Screw Pump eliminates blow-back and early failure from abrasive wear; it reduces excessive maintenance and unplanned, costly downtime. During fabrication and assembly, the screw pump is optimized for your specific feeder needs.

Benefits:

• Increased conveying rates with less air
• No blowback, even when running empty
• Increased resistance to abrasive materials
• Low Profile
• Fully warranted and guaranteed
• Longer bearing life/fewer system shutdowns
• Reduced operating and maintenance costs

Features:

• Heavy Steel Channel Frame
• Quad Seal
• Integral check valve
• Hard coated shaft assembly
• Low inlet hopper height
• Three conveying air inlet points
• No product contact with bearings
• Temperatures up to 450°F
• Low conveying pressure -4 to 12 PSI
• Oversize Bearings
