Warren Rupp was founded in 1965 by Warren E. Rupp and Charles E. Young, Jr., in Mansfield, Ohio

Founding Goal:
To fill exceptional pumps needs, abrasive and viscous substances in particular.

Current Position:
Warren Rupp holds a leading position in the air-operated, diaphragm pump market with the broadest range of pump sizes, types and models. Marketed primarily under the tradename of SandPIPER® Pumps.

Markets Served:
Principal markets served by a SandPIPER pump include chemicals, paints, food processing, electronics, construction, industrial maintenance, utilities, process industries, wastewater and sludge processing, and mining.

SandPIPER pumps and parts are sold worldwide through a network of independent, factory-authorized distributors. Product is marketed in over 60 countries, in nearly every major trading area. Sales to international customers account for a substantial portion of SandPIPER's revenues.

Product Profile:
SandPIPER pumps are manufactured in aluminum, cast iron, stainless steel, Hastelloy, polypropylene, PVDF, Nylon and Conductive Acetal. Self-priming and Seal less, they are ideal for pumping abrasive, semi-solid, corrosive and shear sensitive materials. They are also chosen for applications where electricity is not available, or cannot be used due to safety conditions ATEX. Diaphragm pumps provide pollution-free and energy-efficient operation, with fewer moving parts than conventional motor-driven pumps.

Competitive Advantages:
A SINGLE, no-stall air drive system (ESADS®) on all models provides GUARANTEED no-stalling performance, eliminating the need to choose among technologies for different operating conditions.

The INNOVATION of SandPIPER provided the first BOLTED AODD pump design (35 years ago) that continues to provide service life in excess of service intensive V-band designs.

New innovations include "RuppGUARD™ Spill Prevention" models from SandPIPER. These AODD pumps are comprised of a primary and secondary pumping diaphragm for each chamber separated by an inert, compatible fluid barrier. Buyer motivations include:

  • For hazardous fluids (example: hydrochloric acid) a pump diaphragm failure does not stop the pump from finishing batch transfer, and provides protection of the environment by preventing fluid from entering and being exhausted through the air exhaust.
  • Maintenance costs are significantly reduced for many fluids because in the event of a diaphragm failure, the air drive system is not contaminated or in need of extensive cleaning or replacement.
  • Air is prevented from entering the fluid being pumped, so critical applications (example: ceramic slip) where air mixed with the transfer fluid would degrade the final product can be performed reliably even in the event of diaphragm failure.
  • In short, the RuppGUARD™ Spill Prevention models offer benefits unequaled by the competition that provide the least risk and best value for critical process applications.

SandPIPER also enjoys many intangible advantages. The company is known to stand behind the product with a generous 5 year warranty policy, money-back guarantees, and factory-based training, education and troubleshooting. The Technical Services and Engineering Departments are available to all users and distributors. The company's distributors are known as highly professional companies around the world.
