The Warren Rupp-designed and manufactured Sandpiper pneumatic double diaphragm pump was the first in the industry to pass the ISO9001 system and ISO4001 environmental management system. It can be applied in any industrial field, with a simple design and numerous features.

Metal diaphragm pump materials: cast iron, aluminum alloy, stainless steel,

Rubber materials: nitrile, neoprene, fluororubber, PTFE, Teflon.

Port sizes: 1/2", 1", 1.5", 2", 3"

Flow rate varies depending on the port size.

Operating pressure (bar) head: 6.9

Plastic diaphragm pump materials: engineering plastic, F46-lined, rubber-lined.

Rubber materials: nitrile, neoprene, fluororubber, PTFE, Teflon.

Port sizes: 1/2", 1", 1.5", 2", 3"

Flow rate: 0-889 l/min, varies depending on the port size.

Operating pressure (bar) head: 8.6

By selecting the pump body housing and diaphragm materials, it can handle various strong acids, strong alkalis, and aggressive liquid media.
