York Fluid Controls carries Sandpiper’s innovative Signature Series air operated double diaphragm pumps The Sandpiper Signature Series includes three models of innovative, high-performance pumps.

Sandpiper has engineered these pumps to deliver industry-leading durability and performance, even for extremely severe tasks and work environments, and features a wide range of applications.

The Signature Series is capable of supporting a very wide range of pumping applications. All three of these AODD pumps can handle water, suspended solids, high-viscosity liquids, and corrosive fluids; all three also are suitable for both intermittent and continuous duty, as well as multiple types of installation.

York Fluid Controls offers all three models, including the Signature heavy-duty flap valve pump. Its construction has a large flow area and allows up to line-size solids to pass directly through the pump. The bottom discharge porting enables solids to pass through instead of settling inside the chamber, eliminating premature wear and damage. Other key benefits include dry prime suction lift of up to 24 feet in water and minimal maintenance.

The Signature line of heavy-duty ball valve pumps are built for fluids containing settling, suspended, or floating solids. These AODD pumps have down-, top-, or side-ported options, the first two for containing solids and the other for use in confined spaces. Another advantage is the weighted check valve balls, each of which features a metallic core that is 30 to 60 per cent heavier than a solid rubber check ball, which helps to boost performance with viscous fluids. Other benefits include diaphragm wear pads and heavy-duty actuator plungers.

Signature’s series of containment-duty ball valve pumps is the only complete line of AODD pumps with superior containment of hazardous fluids, which protects employees, the environment, and the pumps themselves. A key benefit is visual leak detection, which alerts users of any diaphragm breaches before any system fluid can escape. Other advantages are simple repairs and elimination of expensive, time-consuming cleanup.
