The name SANDPIPER originated during the development of the first Air Operated Double Diaphragm (AODD) pump by Warren Rupp. AODD pumps were designed to handle solids of any appreciable size. To accelerate wear during the development of the pump, a slurry of very abrasive silica sand was continuously cycled through the pump. The sand slurry often wore through the piping before the pump failed. Since the sand was pumped through a pipe, Warren E. Rupp, the company founder, named the pump the SANDPIPER.
The SANDPIPER brand now includes:
Heavy Duty Ball
Heavy Duty Flap
Containment Duty (metallic and non-metallic)
Standard Duty Ball (metallic and non-metallic)
High Pressure Duty
Special Duty - UL pumps, filter press, USDA, mine construction, natural gas-operated, dewatering and wastewater
Designed for applications where 100 PSI maximum pump operating pressure is insufficient to overcome system requirements. The flow rate is roughly half of the equivalent size pump output, though a maximum discharge pressure of 200 PSI can be achieved with only 100 PSI air inlet pressure supplied.
Port Sizes : 3/4" through 3"
Capacity : 1 to 100 GPM
Construction : Stainless Steel, Cast Iron, or Aluminum wetted materials
Diaphragm : Choice of six elastomers
Controls : No elaborate bypass, relief valves, or complicated controls required. Excellent pressure retention.
Yamada FDA compliant pumps are specifically designed for Food, Pharmaceutical & Cosmetic industries where 3A or USDA standards are not required.
Pumps include 316 Stainless Steel wetted components with Passivated Satin Finish, Epoxy-Coated Air Motor, Sanitary Clamp Fittings, and FDA compliant elastomers: Hytrel®, EPDM and PTFE.
Port Size : Eight sizes available from 3/4" to 4" ports
Flow Ranges : From 1 to 215 gallons per minute
Air Pressure : From 20 to 100 PSI.
Additional Options : Air motor Teflon-coated or Electroless Nickel Plate
Finish : Interior mechanical polish available on most models. Consult Yamada
Note: FDA Series pumps utilize oversized sanitary ports
