AIR OPERATED FLUID PUMP LA401
Product Description
Feature
(1) Pump moves and oil suction are two separation system, it won't contaminating grease.
(2) Typically used in workshops, service stations, fleet maintenance, mining, agriculture, armed forces, construction, trains, etc.
(3) The pump is made of aluminum alloy by forging.
(4) It can hold 200 liters (50 gallons) for each country.
Usage
(1) General 00#~3# grease all can be infused into smoothly.
✅The key to determining this is the NLGI consistency grade of the lubricating oil.
Proper use of the pressure plate ensures smooth oil extraction and prevents the pump from running dry.
✅NLGI #00, #0 (semi-flow, extremely soft): No need to use
The oil has good fluidity and can flow to the pump inlet on its own.
✅NLGI #1 (soft, paste): Add as needed depending on environmental conditions. Generally, it is not required.
Special Note: If operating in winter or low-temperature environments, the oil may harden due to temperature drop. It is recommended to install a pressure plate to maintain a stable oil supply.
✅NLGI #2 (Medium consistency): Must be used
This grade of oil has lost its fluidity to automatically flow to the suction inlet. Please be sure to install a pressure plate to avoid creating voids (air locks) that could cause pump malfunction.
✅NLGI #3 (High viscosity, firm texture): Requires increased pressure support.
If a regular pump is difficult to extract the material, it is recommended to use an HV series pressure pump, which uses a pneumatic cylinder to apply strong downward pressure.
✅If you require extraction of high-viscosity oils, please contact our technical team directly.
(1)Without pressure plate. It will be hollow after sucking and also not easy to suck.
(2)A pressure plate is used. The grease can be sucked evenly and smoothly with follower plate.

| Advantages Analysis | 1. High stability: The pump action and oil extraction are independent systems, and the compressed air does not contaminate the grease. | 1. Higher output pressure: The 55:1 pressure ratio can handle butter with slightly higher viscosity. | 1. Maximum thrust: 80:1 pressure ratio, designed for cold regions or ultra-high viscosity greases. | 1. The pressure plate is tightly fitted to the container to reduce residual oil. |
| 2. Easy to maintain: Simple structure and highly interchangeable parts. | 2. Efficiency optimization: Under the same air pressure, the oil output speed and force are superior to the LA series. | 2. Excellent durability: Internal components are optimized for wear resistance in extreme environments. | 2. It can extract high-viscosity oils that are difficult to handle with ordinary pumps. | |
| 3. Excellent material: Made of high-strength aluminum alloy forging. | 3. Lower noise level (compared to our company's LA series) | 3. The output is extremely stable. | ||
| Disadvantage Analysis | 1. The pressure is relatively low, resulting in weaker power when dealing with extremely high viscosity butter or long pipelines. | 1. The air compressor requires precise gas cleanliness (moisture filtration) to maintain high-pressure sealing. | 1. The price is relatively high. | 1. The operation settings are rather cumbersome. |
| 2. Due to the extremely high pressure, extra care must be taken to ensure the safe load on the hoses and connectors during operation. | 2. The structure is relatively complex, and the maintenance cost is relatively high. | |||
| Usage Recommendations | • The first choice for general repair shops. | • Electronics factory or routine equipment maintenance. | • Heavy industry and harsh environment. | • Quantitative packaging on the production line. |
| • Offers the highest cost-performance ratio, meeting the maintenance needs of most vehicles and general machinery. | • Recommended for those with a large workload, need for rapid operation, or long pipelines. | • For example, in mining, mining machinery, and maintenance of large public works equipment. | • Printing plants (inks), high-viscosity industrial greases, and special quantitative requirements. | |
| • Recommended for long-distance oil transportation, or in situations involving significant elevation differences and varying environmental conditions. | ||||
