Liquid Anhydrous Ammonia Transfer Pump

A robust positive-displacement vane transfer pump engineered for safe, reliable handling of liquid anhydrous ammonia and other similar volatile liquids (methanol, dimethyl ammonium, propylene oxide, ethylene oxide, isobutylene, butadiene, crude benzene, chloride methane).

Key features

• Designed as a rotary positive-displacement vane pump for stable, metered transfer — flow is proportional to shaft speed.
• Heavy-duty, abrasion-resistant construction: alloy cast-iron pump casing with precision machining to minimize leakage and improve wear life.
• Special-formulation vanes and seals for high abrasion resistance, toughness and sealing performance under ammonia service.
• Well-sealed design with oil-block separation between suction and discharge cavities to reduce internal leakage and protect sealing components.
• High and stable delivery pressure suitable for transfer, loading/unloading and circulation duties in industrial installations.

Typical applications

• Transfer and circulation of liquid anhydrous ammonia in refrigeration, fertilizer production and chemical processing.
• Handling of other volatile, low-viscosity chemical liquids with properties similar to ammonia (see compatibility requirements).
• Use in gas, petroleum, chemical, pharmaceutical and metallurgical plants for loading/unloading and process circulation.

Design & operating notes

• The stator, rotor, baffles and vanes form multiple sealed cavities; as the rotor turns, cavity volume increases to draw liquid in and then decreases to discharge it.
• Vanes are held against the stator by centrifugal force and a dual-baffle arrangement to maintain tight sealing and steady flow under rated conditions.
• Model nomenclature: YAB15-5 — “YAB” = liquid ammonia pump family; “15” = rated flow designation; “5” = pressure boost (pressure difference between inlet and outlet). Confirm units for flow and pressure with the supplier.

Selection & safety considerations

• Verify chemical compatibility of seals and vane materials for liquids other than ammonia before selecting the pump.
• Ensure appropriate safety measures and instrumentation are in place when handling anhydrous ammonia (venting, leak detection, emergency shutdown, training).
• For system integration, confirm required drive speed, connection sizes, rated flow and pressure lift with technical datasheets.
