Yqb Lpg Transfer Pump

Industrial positive-displacement rotary vane pump engineered for safe, reliable transfer of liquefied petroleum gas (LPG) and other volatile, low‑viscosity liquids. The YQB series is built for loading/unloading LPG trucks, cylinder filling, workshop feed and similar bulk transfer tasks where steady, metered flow and robust sealing are required.

Key features

• Positive-displacement rotary vane design delivers steady flow proportional to shaft speed (flow ≈ rpm), making it suitable for dosing and metered transfer operations.
• Composite-curve stator profile and eccentric rotor create sealed cavities that produce reliable suction and discharge without excessive pulsation.
• Vanes are held against the stator by centrifugal force and twin baffles, ensuring consistent contact and long service life under rated conditions.
• Mechanical sealing arrangement on both ends with O-ring on the fixed mating faces; rotating faces are metal-to-nonmetal for dependable sealing in LPG and similar services.
• Multi-purpose, compact construction optimized for volatile hydrocarbons and compatible chemicals listed for the series, including dimethyl ether, methyl chloride, ethylene oxide, propane, propylene, butadiene, isobutylene, methanol and similar petroleum products.

Operational notes for B2B buyers

• Typical applications: LPG truck loading/unloading, cylinder filling stations, plant feed lines and workshop supply systems.
• Performance is speed-dependent; confirm required flow at the intended drive speed and system backpressure when selecting the pump.
• Install appropriate suction and discharge controls, pressure relief and grounding/bonding per local codes when handling flammable or volatile fluids.
• Routine inspection and replacement of vanes and mechanical seals will maintain performance and safety.

Benefits

• Reliable, low-pulsation transfer for flammable/volatile liquids
• Compact, multi-purpose design suited for on-site transfer and filling operations
• Proven sealing arrangement tailored for LPG service

For technical selection, provide required flow (m3/h or L/min), discharge pressure, fluid specification and intended drive speed so the correct size and materials can be recommended.
