Containment Duty Pumps, Metallic & Non-Metallic

AODD Pumps Engineered For Superior Fluid Containment

When working with hazardous fluids, even a small leak can create safety risks, environmental hazards, and expensive downtime.

SANDPIPER Containment Duty Pumps are built for challenging environments. With a two-diaphragm design and a sealed containment chamber, these pumps keep process fluid where it belongs, even in the event of a diaphragm failure. A visual leak indicator provides early warning, and optional electronic or mechanical detection can be added when automated monitoring is required. The result? Safer operations, less downtime, and greater peace of mind.

Key Features:

• Sizes: 1 – 3" (25 – 76 mm)
• Flow: 42 – 238 gpm (159 – 901 lpm)
• Solids handling: ¼ – ⅝" (6 – 18 mm)
• Construction (Metallic): Aluminum, Cast Iron
• Construction (Non-Metallic): Polypropylene, PVDF
• Elastomers: PTFE, Neoprene, Fluorocarbon, Santoprene®
• Sealed containment chamber creates a barrier between the Air Side and Wet Side
• Leak detection options include a visual indicator standard, with electronic or mechanical monitoring available
• ESADS+Plus air distribution system allows easy in-line maintenance

Built to Protect What Matters Most

When handling hazardous or corrosive fluids, the stakes are high. SANDPIPER containment duty diaphragm pumps are designed to keep your operation safe, compliant, and productive.

• Protect people and equipment. A containment chamber sits between the pumping and driver diaphragms, forming a sealed barrier between the Air Side and Wet Side.
• Stay compliant, avoid costs. Leaks are caught before fluid escapes, helping facilities meet environmental and safety standards.
• Minimize downtime. Like all Signature Series pumps, these models include ESADS+Plus, allowing fast in-line access to the air valve when maintenance is needed, keeping downtime to a minimum.

Where Containment Duty Pumps Are Essential

Containment Duty Pumps are most valuable in operations where secondary protection, compliance assurance, and material compatibility aren’t optional—they’re required. If the consequences of a leak extend far beyond the pump itself, this could be the right fit.

• Chemical processing. Containment prevents corrosive or toxic fluids from escaping into the plant environment, protecting operators and ensuring processes stay compliant.
• Waste treatment. Handles hazardous byproducts with built-in containment, reducing risk during transfer and keeping facilities aligned with environmental standards.
• Regulated industries. Meets requirements for secondary containment in processes where zero fluid loss is mandated.
• Critical materials. Provides added protection when handling high-value or sensitive fluids, where every drop matters to safety and the bottom line.
