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.

About MARATHON Pumps
Warren Rupp, Inc., a Unit of IDEX Corporation, pioneered the design and manufacture of air-operated, double diaphragm pumps. MARATHON diaphragm pumps are driven by compressed air. The directional air distribution valve and pilot valve, referred to as the "air end," are located in the center section of the pump. Liquid moves through two manifolds and outer chambers of the pump, referred to as the "wet end." Generally, check valves (ball-type or flap-type) are located at the top and bottom of each outer chamber or on a common manifold. The two outer chambers are connected by suction and discharge manifolds. The pumps are self-priming.
The MARATHON brand now includes:
Heavy Duty Flap - metallic
Standard Duty Ball (metallic and non-metallic)
Submersible
Metallic Materials: Aluminum, Cast Iron, Stainless Steel and Alloy C
Non-Metallic Materials: Polypropylene, PVDF, Nylon and Conductive Acetal
