Durable, Reliable AODD Pumps Critical to Steel and Metal Production

Metal processing is one of the oldest and most demanding industrial markets. The range of pumping needs in this market go from raw metal processing to precise metal finishing and coatings applications.

SANDPIPER offers an extensive portfolio of air-operated double-diaphragm (AODD) pump designs able to be configured with a variety of material combinations for maximum compatibility and reliability across harsh metal processing applications. Our portfolio addresses common problems in the metal processing industry, such as metal chips, debris, settling solids, caustic and acidic chemical handling, and coatings with these design features:

• Flap valve design for removal of debris, sediment, solids, metal chips and shavings
• Self-draining design eliminates solids buildup in the bottom of the diaphragm chambers to avoid diaphragm failure or damage
• Guaranteed non-stall design provides consistent, uninterrupted operation with minimal downtime
• Corrosion-resistant center air section reduces wear and costly repairs
• Spill containment pump designs to safely and reliably prevent leakage to the environment and keep your workforce safe
• Bolted, thick-wall construction improves reliability and offers longer MTBF compared to a clamped construction
• High pressure 2:1 ratio pump for filter press caking applications offering maximum efficiency, reducing teardown and cleaning time
• Externally Serviceable Air Distribution System (ESADS) a SANDPIPER exclusive feature allows complete access to the main air and pilot valves without removing the pump from service, reducing your downtime by as much as 90%.
• Five-year limited warranty
• Connecting rod guarantee

COMMONLY USED AODD STEEL AND METAL APPLICATIONS

• Filter press: Removal of metal particles so water can be reclaimed and reused
• Sump/wastewater: Removal of processing waste involving sludge and solids handling without diaphragm failures
• Loading/unloading/transfer: Corrosive caustic chemicals, acid and slurry transfer to wastewater tank or process
• Process/manufacturing: pumping and recirculating chemicals in manufacturing processes such as pickling and metal surface treatment
• Cleaning: Washing, de-oiling and degreasing
