HAYES GROUP AND SANDPIPER: BOOST AODD PUMP EFFICIENCY WITH ESSENTIAL ACCESSORIES

Ensuring your operations run smoothly with minimal downtime is what Hayes Group does best. Our partnership with Sandpiper means that beyond offering reliable air-operated double-diaphragm (AODD) pumps, we provide genuine Sandpiper accessories that elevate pump performance and longevity.

Key Accessories to Optimize Your AODD System

Pulsation Dampeners

Tranquilizer® pulsation dampeners are essential for maintaining smooth, pulse‑free flow and stable liquid pressure in diaphragm pump systems. Using a flexible diaphragm to absorb pressure surges and water hammer, they protect downstream equipment and extend overall system life. Tranquilizer dampeners are selected primarily by pump size, and wetted materials can be mixed as needed—for example, pairing a non‑metallic pump with a metallic dampener.

Sandpiper Tranquilizer pulsation dampeners include:

• DA Series – For ¾″ and smaller pumps; manual‑charge design with PTFE diaphragm, compact and versatile, ideal for S05–S10 pump sizes

• DC Series – Inline discharge‑mounted dampeners for 1″ and larger pumps; automatically charged using the pump’s air supply, offering simple installation and effective surge suppression across a wide range of applications

• TA Series – Self‑adjusting dampeners for 1″ and larger pumps; automatically inlet and exhaust air to maintain optimal performance, available in multiple metallic and non‑metallic configurations for demanding industrial services

Filter Regulators

Compressed air is often warm, wet, and contaminated - even at the supply source. Filter regulators remove debris and moisture while ensuring clean, consistent pressure for the air valve. The result:

• Protection against dirt and moisture for seals and valves

• Prevention of icing in cold environments

• Reduction of wear with more precise air delivery

Liquid Level Controllers

Dry-running AODD pumps can cause serious damage and inefficiency. Pneumatic liquid level controllers use a float-activated air valve to prevent such wastage with:

• Fully pneumatic operation (no electricity required)

• Ability to maintain desired tank levels

• ATEX-certified safety for hazardous zones

• Applications in sump, dewatering, tank filling, and fluid transfer

Why These Accessories Matter

• Maximize uptime: Reduce pump and system wear from pressure spikes, dry cycling, and icing.

• Protect downstream systems: Maintain consistent flow to safeguard instrumentation and connected equipment.

• Optimize performance: Cleaner air, stable pressure, and reliable liquid levels translate to smooth, efficient operations.
