The YEEDA YD51-009/010/011 Vertical Pneumatic Oil Pump Series addresses the pain points of high-viscosity oil transfer: "unsmooth pumping, high wear, and limited viscosity adaptability". With "air-operated efficiency + double-action design + viscosity-specific compatibility" as core strengths, each model targets distinct user needs:
- Low-Maintenance Smart Design: Fewer parts reduce wear and tear, cutting maintenance frequency by 40% compared to traditional pneumatic pumps. The adjustable 2" bung adapter fits most standard drums, eliminating the need for custom fittings.
- Stable Differential Air Motor: Ensures consistent pumping even for SAE80 oil, avoiding "stuttering" common in low-pressure pumps. Its 18 L/Min relative capacity meets daily needs of small workshops.
- Double Action & Self-Priming: Delivers fast, precise flow rates--30% faster than single-action pumps. The self-priming function skips pre-filling, saving 5 minutes of setup time per drum.
- SAE130 Compatibility: Handles medium-to-high viscosity oils (e.g., heavy gear oil), making it ideal for heavy machinery like tractors or excavators. The 24 Bar max flow pressure supports vertical transfer to small tanks.
- 5:1 Compression Ratio: Delivers 40 Bar max flow pressure, enabling smooth transfer of SAE240 high-viscosity oil (e.g., industrial gearbox oil) that clogs standard pumps.
- Enhanced Air & Oil Connections: F1/2"G air inlet and F3/4"G oil outlet improve flow efficiency; 125 L/Min air consumption ensures consistent power for long-duration use in factories.
Scenario Requirement: A car repair shop changes oil for 20 cars daily (each needing 4L SAE50 motor oil) from 200L drums. The shop needs a low-maintenance pump.
Operation Process:
- Setup: Attach YD51-009 (730mm suction tube) to a 200L drum via the 2" adapter; connect F1/4"G air inlet to the shop's air compressor;
- Transfer: Pump 4L oil per car in ~13 seconds (18 L/Min capacity);
- Efficiency: 20 cars serviced in ~4.3 minutes; smart low-part design reduces monthly maintenance to 1 time;
- Compatibility: Handles SAE50 oil easily; adjustable adapter fits all shop drums.
Effect: Low maintenance saves time; stable flow meets daily workshop needs.
Scenario Requirement: A farm services 8 tractors (each needing 15L SAE120 gear oil) weekly. The farm uses medium-distance transfer (5m) and needs fast pumping.
Operation Process:
- Setup: Use YD51-010 (940mm tube) with 2" adapter; connect air inlet to a portable compressor;
- Transfer: Double-action design delivers 15L oil in ~50 seconds; self-priming skips pre-filling;
- Durability: 24 Bar max pressure handles 5m transfer; no wear after 8 weekly refuels;
- Convenience: Lightweight design allows 1-person operation.
Effect: Fast flow saves labor; SAE120 compatibility fits tractor needs.
Scenario Requirement: A manufacturing plant refuels 10 industrial gearboxes (each needing 20L SAE220 oil) monthly. The oil has high viscosity, requiring powerful pumping.
Operation Process:
- Setup: Deploy YD51-011 (1250mm tube) for deep drums; connect F1/2"G air inlet to factory air supply;
- Transfer: 5:1 compression ratio pumps 20L SAE220 oil in ~1.2 minutes (14 L/Min capacity);
- Safety: 40 Bar max pressure ensures smooth flow without clogging; F3/4"G outlet prevents oil leakage;
- Reliability: Handles SAE220 oil without performance drop; monthly use shows no part wear.
Effect: High viscosity compatibility solves factory pain points; powerful pressure enables stable transfer.
A1: Slow flow for high-viscosity oil is usually due to insufficient air pressure. Solutions:
- Check Air Pressure: Ensure the air compressor provides 8 Bar working pressure (low pressure reduces flow);
- Clean Suction Tube: Remove the 42mm tube and flush with diesel to clear oil residue;
- Adjust Adapter: Ensure the 2" bung adapter is tightly sealed--air leaks reduce pump power. These steps restore 18 L/Min flow.
A2: No. Exceeding the SAE130 limit will strain the pump's 3:0 compression ratio, causing:
- Reduced Flow: The pump may only deliver 10-12 L/Min (40% lower than rated);
- Increased Wear: High viscosity forces parts to work harder, shortening service life by 50%;
- Clogging Risk: Thick oil may block the M1/2"G outlet. For SAE140+, use YD51-011 (SAE240 compatible).
A3: Self-priming failure is typically due to air gaps or oil residue. Fixes:
- Inspect Connections: Ensure the air inlet (F1/2"G) and oil outlet (F3/4"G) are tightly connected--air gaps break the vacuum;
- Prime Manually: Pour 200ml of low-viscosity oil (e.g., SAE30) into the suction tube to initiate vacuum;
- Clean Valves: Disassemble the double-action valves and wipe oil residue--gummed residue prevents self-priming.
A4: Base the choice on oil viscosity and needs:
- YD51-009: For SAE80 or lower (e.g., automotive motor oil) in small workshops--prioritizes low maintenance;
- YD51-010: For SAE130 or lower (e.g., tractor gear oil) in farms/medium shops--needs fast double-action flow;
- YD51-011: For SAE240 or lower (e.g., industrial gearbox oil) in factories--requires high viscosity compatibility. All models fit short-to-medium transfer distances.
