About SANDPIPER

SANDPIPER is a manufacturer of air-operated double diaphragm (AODD) pumps and related accessories, with a product history dating back to the 1960s. The brand is known for its SPB and HDB series pumps, which are used in industrial fluid-transfer applications where electric motors are impractical or unsafe. 3G Electric supplies SANDPIPER AODD pumps, repair kits, and air kits to maintenance and procurement teams worldwide.

The SANDPIPER line includes pumps with aluminum, cast iron, and stainless steel housings, covering connection sizes from 1 inch to 4 inches. Flow rates range from 45 gpm to 310 gpm, with maximum heads up to 289 ft. Wetted materials vary by model and include stainless steel, PTFE, Buna-N, Neoprene, and Santoprene. Many models carry ABS Type Approval, CE marking, and EAC certification, and are built to ISO standards. These pumps handle abrasive, viscous, and shear-sensitive fluids, and are commonly specified for chemical transfer, wastewater, and process applications.

3G Electric stocks genuine OEM repair kits for SANDPIPER pumps, including fluid-end and air-end kits. Fluid-end kits, such as the 476.042.360 Buna-N kit for 2-inch pumps, include elastomers and components to restore sealing and flow performance. Air-end kits, such as the 476.428.000 kit, contain seals and replacement parts for the air motor section. Air kits like the AC8DFB (part 476.227.000) provide the necessary components for air-side maintenance. These kits are identified by manufacturer part numbers and are cross-referenced to pump series and sizes.

For technical buyers, SANDPIPER pumps offer several specification points: air inlet sizes of 3/4 in NPT on larger models, NPSHr values as low as 5 ft, and flange or NPT connection options. The pumps are designed for ease of maintenance, with modular air and fluid sections that can be serviced independently. 3G Electric supports the line by providing pump selection assistance, access to OEM spare parts, and global shipping. The product range includes pumps for general transfer, drum unloading, and sump applications, with options for different diaphragm and valve materials to suit specific fluid compatibility requirements.

Frequently asked questions

Common questions about SANDPIPER from 3G Electric.

What is the maximum flow rate available in SANDPIPER aluminum housing AODD pumps?

SANDPIPER aluminum housing AODD pumps include models with flow rates up to 310 gpm. For example, the 3-inch flange connection model (SKU 6WY81) delivers 310 gpm with a maximum head of 231 ft. The 4-inch flange connection model (SKU 408LN5) delivers 303 gpm. Flow rates depend on pump size, air supply, and fluid characteristics. These pumps are suitable for high-volume transfer applications where aluminum is compatible with the process fluid.

What is included in a SANDPIPER fluid-end repair kit?

A SANDPIPER fluid-end repair kit includes the elastomers and components needed to rebuild the fluid section of an AODD pump. For instance, the Buna-N kit (part 476.042.360) for 2-inch pumps contains diaphragms, valve balls, seats, and seals. The kit restores sealing and flow performance. Kits are specific to pump size and material configuration. 3G Electric supplies genuine OEM fluid-end kits, and buyers should verify the pump model and wetted materials before ordering.

What are the typical applications for SANDPIPER stainless steel AODD pumps?

SANDPIPER stainless steel AODD pumps, such as the HDB3 series (SKU 6WY93), are used in applications requiring corrosion resistance and compatibility with aggressive fluids. The 316 stainless steel body and PTFE wetted parts make them suitable for chemical transfer, pharmaceutical, and food processing where contamination must be minimized. These pumps handle flow rates up to 260 gpm and are available with various diaphragm materials. They are often specified for clean-in-place (CIP) systems and hazardous area installations.

How do I select the correct SANDPIPER air-end repair kit for my pump?

To select the correct SANDPIPER air-end repair kit, identify the pump series and size from the nameplate or manual. Air-end kits are designated by manufacturer part numbers, such as 476.428.000 for certain models. The kit includes seals and components for the air motor section. Because kits vary by pump model, consult the pump documentation or contact 3G Electric with the pump model and serial number. Using the correct kit ensures proper fit and restoration of operational integrity.

What connection types are available on SANDPIPER cast iron AODD pumps?

SANDPIPER cast iron AODD pumps are available with flange or NPT connections, depending on the model. For example, the 4-inch flange model (SKU 408LM9) delivers 303 gpm, while the 1-inch NPT model (SKU 29AU57) delivers 45 gpm with a maximum head of 289 ft. Connection type affects installation and flow characteristics. Cast iron pumps are typically used for abrasive or viscous fluids where the material's durability is beneficial. Verify connection size and type against your piping requirements.
