Product Advantages

Higher Pressure Ratio
The 5:1 configuration provides greater theoretical pressure multiplication than a 3:1 pump, making it worth considering for applications requiring higher oil delivery pressure.

Practical Oil Dispensing Performance
The listed 14 L/min flow rate supports routine transfer and dispensing operations within the pump’s operating limits.

Service-Friendly Design
The detachable structure is designed to facilitate maintenance and repair work.

Flexible Pipe Length Selection
Multiple listed pipe lengths provide options for different container arrangements and installation requirements.

Frequently Asked Questions

1. How should I choose between the AC-OP-1 and AC-OP-2?

The AC-OP-1 is a 3:1 pump listed at 18 L/min and 24 bar maximum oil pressure. The AC-OP-2 is a 5:1 pump listed at 14 L/min and 40 bar maximum oil pressure. The AC-OP-2 offers a higher pressure ratio, but its listed flow rate is lower. Choose based on the system’s required pressure, flow and oil characteristics.

2. Does the AC-OP-2 always operate at 40 bar?

No. The 40 bar figure is the listed maximum oil pressure, not a guaranteed constant operating pressure. Actual pressure depends on air supply conditions, fluid resistance and the connected system. The pump and all connected components must operate within their rated limits.

3. What compressed-air supply and connections are required?

The catalogue lists an 8 bar working pressure, a 1/4-inch female air inlet and a 1/2-inch male oil outlet. It also lists air consumption of 125 L/min. Confirm the compressor’s available capacity and the exact connection standards before installation.

4. How can I select the right pipe length for the AC-OP-2?

The listed options are 270 mm, 730 mm, 940 mm and 1250 mm. Selection should account for the oil container, mounting arrangement and required insertion depth. Confirm the pipe length measurement and compatibility with the intended container before ordering.

5. What should be confirmed about the catalogue’s SAE 240 reference?

The catalogue lists SAE 240 under an oil cleanliness reference, but the exact meaning and measurement method are not defined. Since SAE designations can also refer to oil viscosity grades, ask the manufacturer to clarify the intended specification before using it as a technical acceptance criterion.
