Product Details
YD51-001/YD51-002 Aluminum-Hand Rotary Pumps address the pain points of liquid transfer: "cumbersome electric pumps, limited portability, and debris-induced clogging". With "all-aluminum durability + reversible action + filter protection" as core strengths, the two models cater to different flow needs, delivering efficient, manual transfer for diverse scenarios:
All-Aluminum Construction: Lightweight & Corrosion-Resistant
- Rust-Free Durability: The pump body, inlet/outlet pipes, and handle frame are made of cast aluminum - a material that resists corrosion from oil, water, and mild chemicals. Unlike iron pumps that rust in humid environments, these aluminum pumps maintain functionality for 7+ years, even with outdoor use.
- Lightweight Portability: YD51-001 weighs only 1.5kg (net), and YD51-002 weighs 2.2kg - both can be carried by one person to remote locations (e.g., farm fields, outdoor maintenance sites) where electric pumps can't reach. The compact size also fits in small storage spaces (e.g., garage cabinets, toolboxes).
Reversible Action & Filter Protection: Versatile & Low-Maintenance
- Bidirectional Transfer: The reversible action allows both "suction" (drawing liquid from a tank) and "discharge" (pushing liquid into a container) - eliminating the need for two separate pumps. For example, YD51-002 can transfer oil from a drum to a vehicle (forward) and drain excess oil back to the drum (reverse), improving workflow flexibility.
- Debris Blocking: The built-in copper mesh filter (installed at the inlet) intercepts dirt, metal shavings, and other debris, preventing them from entering the pump core and causing clogging. This reduces maintenance frequency by 80% compared to unfiltered pumps, as the filter is easy to remove and clean.
Tailored Flow Rates: Fit Small & Large Tasks
- YD51-001 (30 Lpm): Ideal for small-scale tasks like refueling lawnmowers, topping up car engine oil, or transferring water for home gardening. The 30 Lpm flow rate balances speed and control - no overflow when handling small containers (e.g., 5L oil cans).
- YD51-002 (50 Lpm): Designed for large-volume transfer, such as filling farm machinery with diesel, transferring water to irrigation tanks, or emptying industrial waste oil drums. The 50 Lpm flow rate cuts transfer time by half compared to YD51-001, making it a time-saver for commercial use.
Application Scenarios
Home Garage & Small Workshop (YD51-001)
Scenario Requirement: A home garage owner needs to transfer 20L of engine oil from a 200L drum to 5L oil cans for car maintenance. The garage has limited space, and no power outlet is nearby.
Operation Process:
- Setup: Connect YD51-001's inlet pipe to the drum (φ32mm inlet fits standard drum bungs), attach the 1.25m hose to the outlet (φ25mm), and place the hose over a 5L can
- Transfer: Rotate the aluminum+wood handle at 90rpm - 5L oil is transferred in ~10 seconds per can
- Cleanup: After use, reverse the pump to drain residual oil from the hose, remove the copper filter, rinse it with diesel, and store the pump in a toolbox
Effect: No power needed; compact size fits the garage; controlled flow prevents oil spills.
Farm Diesel & Water Transfer (YD51-002)
Scenario Requirement: A farm needs to transfer 500L of diesel from a storage tank to 10 tractors (50L each) and 300L of water to an irrigation tank. The farm has no electricity in the field.
Operation Process:
- Diesel Transfer: Use YD51-002 to fill each tractor's tank - 50L diesel takes ~60 seconds (50 Lpm flow rate); 10 tractors processed in 10 minutes
- Water Transfer: Reuse the pump (no need to clean for water) to transfer 300L to the irrigation tank - completed in 6 minutes
- Portability: Carry the 2.2kg pump between the storage area and field; the polyethylene hose resists kinking on rough ground
Effect: High flow saves time; reversible action works for both diesel and water; portable for field use.
Industrial Waste Oil Handling (YD51-002)
Scenario Requirement: A small manufacturing workshop generates 400L of waste oil monthly, which needs to be transferred from small collection bins to a large waste oil drum. The workshop requires a pump that resists oil corrosion.
Operation Process:
- Setup: Attach YD51-002's inlet to a collection bin (φ36mm inlet fits bin openings), connect the hose to the large drum
- Batch Transfer: Transfer 20L from each bin - 400L (20 bins) processed in 16 minutes; the copper filter traps metal debris from the waste oil
- Maintenance: After monthly use, clean the filter and pump body with diesel; the aluminum construction shows no corrosion
Effect: Oil-resistant materials ensure longevity; high flow handles bulk waste; filter prevents pump damage.
Frequently Asked Questions
Q1: The pump's flow rate slows down when transferring high-viscosity liquids (e.g., gear oil). How to fix this?
A1: High viscosity increases liquid resistance - solutions: 1) Warm the Liquid: For gear oil or thick oil, warm it to 30-40℃ (e.g., place the drum in a warm area) to reduce viscosity; 2) Adjust Rotation Speed: Increase handle rotation slightly (to 100-110rpm, without exceeding comfort) to compensate for slow flow; 3) Use YD51-002: Its larger φ120mm pump core handles high-viscosity liquids better than YD51-001. These steps restore flow efficiency.
Q2: Can the pumps transfer corrosive liquids like acid or bleach?
A2: No. The aluminum construction and polyethylene hose are not resistant to strong acids, alkalis, or oxidizing liquids (e.g., bleach, sulfuric acid). These liquids will corrode the aluminum body and degrade the hose, causing leaks or pump failure. The pumps are only designed for non-corrosive liquids: oil, diesel, water, and mild detergents. Using corrosive liquids voids the warranty.
Q3: The rotary handle becomes loose after repeated use. How to tighten it?
A3: Loose handles are due to worn screws - fixes: 1) Locate the Set Screw: The handle is secured to the pump shaft with a small set screw (usually hex-head); 2) Tighten with a Hex Key: Use a compatible hex key (included with some models) to tighten the screw - do not over-tighten to avoid damaging the aluminum handle; 3) Replace the Screw: If the screw is stripped, replace it with a stainless steel screw of the same size (M4 or M5, depending on the model). Tighten the handle monthly for frequent use.
Q4: How to clean the pump after transferring oil to avoid contaminating water (or vice versa)?
A4: Cross-contamination is prevented with thorough cleaning: 1) Transfer a Rinse Liquid: After oil transfer, pump 5-10L of diesel (for oil) or soapy water (for water) through the pump to flush residual oil/water; 2) Disassemble and Wipe: Remove the inlet/outlet pipes and filter, wipe them with a clean rag; 3) Air-Dry: Let all parts air-dry completely before storing. For YD51-002, the larger pipes are easier to clean - ensure no oil film remains before transferring water.
