II. Product Details (PRODUCT DETAILS)

YD51-003 Series Lever Oil Pumps address the limitations of single-material pumps: "cast iron’s weight, plastic’s chemical vulnerability, and fixed flow rates". With "material diversity + tailored performance + multi-liquid compatibility" as core strengths, each model targets specific transfer needs, delivering reliable manual operation for workshops, farms, and chemical facilities:

1. Material-Specific Durability: Fit Different Liquid Types

  • Cast Iron Models (003A/003B): Built for heavy-duty oil transfer – cast iron resists wear from diesel, engine oil, and hydraulic oil, while NBR seals prevent oil leakage. YD51-003A’s 3m suction head and 5m pump head make it ideal for deep oil drums or vertical transfer, while 003B’s fixed tube ensures stable positioning for long-term use.
  • PP Plastic Models (003C/003D): Lightweight StrongThen PP material (30% lighter than cast iron) is corrosion-resistant to water, alcohol, and gasoline. These models are perfect for environments where heavy cast iron pumps are cumbersome (e.g., mobile farm refueling), and 003D’s compatibility with weak chemicals expands use to light industrial tasks.
  • PPS Model (003E): High-performance PPS material withstands strong chemicals (e.g., mild acids, solvents) that damage PP or cast iron. It retains structural integrity at 120℃, making it suitable for chemical workshops needing safe, non-reactive liquid transfer.

2. Tailored Flow & Suction: Match Transfer Demands

  • High-Flow Heavy-Duty (003A): 20 L/min flow rate handles large-volume oil transfer (e.g., filling farm tractors with 100L diesel in 5 minutes). The 3m suction head reaches the bottom of tall drums, eliminating residual oil waste.
  • Stable Fixed-Flow (003B): 16 L/min flow rate balances speed and control for precise tasks (e.g., topping up hydraulic oil in machinery). The fixed tube design avoids hose kinking, ensuring consistent flow.
  • Balanced Plastic Models (003C/D/E): 19 L/min flow rate suits medium-volume transfer (e.g., 50L gasoline for generators), while the 1m suction head is optimal for standard 200L drums. Their lightweight design (9-12kg) allows 1-person operation.

3. User-Friendly Lever Design: Easy & Efficient

  • Ergonomic Lever Operation: The lever’s length (1370-1380mm) provides mechanical advantage, reducing effort per press – even 003E (11kg) can be operated by one person for 1 hour without fatigue.
  • Seal Reliability: NBR seals (003A/B) and material-compatible seals (003C-E) ensure no liquid leakage, a common issue with generic pumps. The seals are easy to replace, extending the pump’s service life by 50%.
  • Wide Compatibility: Inlet/outlet diameters (35-37mm inlet, 19-22mm outlet) fit standard hoses, eliminating the need for custom adapters. This makes the pumps easy to integrate with existing drum bungs or storage tanks.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Workshop Heavy-Duty Oil Transfer (YD51-003A)

Scenario Requirement: A manufacturing workshop transfers 200L hydraulic oil daily from 200L drums to machinery. The workshop needs a pump that handles deep drums and heavy use.
Operation Process:


  1. Setup: Attach YD51-003A’s 35mm inlet to the drum bung, connect the 19mm outlet hose to machinery; 2. Transfer: Press the lever at 55 RPM – 200L oil transferred in 10 minutes; 3. Efficiency: The 3m suction head empties the drum completely (no residual oil); cast iron body withstands daily use.
    Effect: High flow saves time; cast iron durability resists wear; deep suction eliminates waste.

2. Farm Mobile Refueling (YD51-003C)

Scenario Requirement: A farm refuels 15 generators (each 20L gasoline) daily. The farm needs a lightweight pump for mobile use across fields.
Operation Process:


  1. Portability: Carry 9kg YD51-003C to each generator; 2. Transfer: Attach 37mm inlet to a 50L gasoline can, 22mm outlet to the generator – 20L transferred in ~1 minute; 3. Convenience: PP material resists gasoline corrosion; lightweight design reduces operator fatigue.
    Effect: Lightweight for mobility; corrosion-resistant to gasoline; fast flow for batch refueling.

3. Chemical Workshop Solvent Transfer (YD51-003E)

Scenario Requirement: A chemical workshop transfers 30L mild solvent (e.g., ethanol) daily to mixing tanks. The workshop needs a pump that won’t react with solvents.
Operation Process:


  1. Safety: Use YD51-003E’s PPS body (non-reactive with ethanol); 2. Transfer: Press lever to transfer 30L solvent in ~1.6 minutes; 3. Durability: PPS material remains intact after daily solvent exposure; seals prevent leakage.
    Effect: Chemical resistance ensures safety; stable flow for precise mixing; high-temperature tolerance fits workshop conditions.

IV. Frequently Asked Questions (FAQ)

Q1: YD51-003A’s lever becomes stiff after using for a month. How to fix it?

A1: Stiffness is due to oil residue or lack of lubrication. Solutions: 1) Clean the Lever Joint: Disassemble the lever, wipe oil residue from the pivot with a rag; 2) Lubricate: Apply a small amount of engine oil to the pivot (avoids metal-on-metal wear); 3) Check for Bent Parts: If the lever is bent, straighten it gently (cast iron is brittle – avoid over-force). These steps restore smooth operation.

Q2: Can YD51-003C transfer diesel and water alternately without cleaning?

A2: Yes, but partial cleaning is recommended. Diesel and water are non-reactive with PP, but residual diesel may contaminate water (or vice versa). Steps: 1) After diesel transfer, pump 5L water through the pump to flush residual diesel; 2) Wipe the inlet/outlet with a clean cloth. This prevents cross-contamination and maintains pump performance.

Q3: YD51-003E leaks when transferring strong chemicals. What’s wrong?

A3: Leaks are usually due to seal damage or incompatible chemicals. Fixes: 1) Check the Seal: Replace the PPS-compatible seal if it’s cracked (use original parts – generic seals may react with chemicals); 2) Verify Chemical Compatibility: Ensure the liquid is within PPS’s tolerance (avoid concentrated acids like 98% sulfuric acid); 3) Tighten Connections: Ensure inlet/outlet hoses are tightly secured with clamps.

Q4: How to store the pumps to extend their life?

A4: Storage depends on the model: 1) Cast Iron (003A/B): Clean with diesel, dry thoroughly, and apply anti-rust oil to cast iron surfaces; store in a dry area to avoid rust. 2) Plastic (003C/D/E): Flush with water (for non-chemical use) or compatible solvent (for chemicals), dry, and store away from direct sunlight (prevents plastic aging). 3) All Models: Disconnect hoses, remove seals (if long-term storage), and keep in a dust-free container.
