SANDPIPER Side-Ported and Compact Air-Operated Double-Diaphragm Pump

SANDPIPER’s exclusive 1½” heavy-duty ball pump provides excellent suction lift capabilities and is designed to withstand the most rugged and harsh ball valve pumping applications. The compact 1½” metallic pump has thick-walled construction and is part of our Evolution portfolio improvement. This means this pump has been optimized for the maximum amount of flow capacity with the least amount of air/gas consumption.

The 1½” heavy-duty ball pump is available with a side-ported option, which makes installation easy, optimizes performance on the pumped fluid and solves critical pumping problems.

SANDPIPER Heavy-Duty Ball Valve Pump Features

These pumps are enhanced with extended-wear packages and are your optimal solution for abrasive-slurry applications. Features include:

Side-ported option: For use in confined spaces. Ports are positioned with the center of the pump, allowing for installation in smaller, confined spaces.

Heavy-duty plunger bushings and actuator pins: Designed to withstand severe applications
Diaphragm wear pads: Installed between the diaphragm and outer diaphragm plate, providing a secondary wear surface that extends the life of the diaphragm
Thicker, more robust wetted castings: Provide extended wear resistance
Heavy-duty weighted check valve balls: Are 30-60% heavier than solid rubber check balls, allowing for more consistent chamber filling

ST1½ Metallic Containment-Duty Pump Features

Leak detection: All containment-duty pumps are designed to accommodate visual, mechanical and electronic leak detection devices.
Durability: The durable, bolted construction of the ST1½ is superior to the clamped-band construction pump, providing exceptional leak-free performance.
Serviceability: The air distribution system (ADS) is one of the most frequently serviced parts of any AODD pump. Only SANDPIPER’s ESADS+ feature allows access to the complete ADS without removing the pump from service. Repair or clean in five minutes (versus 55 minutes for competitors). Additionally, the ST1½ offers air-side interchangeability with SANDPIPER’s 1½” (HDB 1½) for reduced inventory costs.
Trusted design: SANDPIPER’s original ADS is fully interchangeable, repairable and inline-serviceable. Other manufacturers frequently change ADS designs, creating issues with interchangeability, obsolete inventory and increased cost of ownership.
