OY1004 High-Flow 2300mL Air Hydraulic Pump

The OY1004 High-Flow 2300mL Air Hydraulic Pump is a pneumatically driven hydraulic unit featuring the largest oil reservoir capacity in its immediate pump family, offering 2,300 mL of usable oil volume to support extended hydraulic operations without the need for frequent refilling cycles. Rated at 1,000 PSI output pressure with an air input requirement of 90 to 140 PSI, it delivers a no-load flow of 42.7 L/min — the highest in its class — with 11 L/min under full load conditions.

The large oil volume and elevated flow rate make this pump suitable for applications requiring sustained hydraulic output over longer work cycles, such as extended pressing operations, continuous clamping sequences, or hydraulic circuit testing where consistent volume delivery matters. The output port is threaded to 1/4"-18NPT. With a net weight of approximately 10.5 kg and package dimensions of 33 × 18.5 × 20 cm, it remains manageable for workshop positioning.

The OY1004 is appropriate for workshops and industrial facilities where longer continuous hydraulic operation cycles are common, and where the 690–1,300 mL reservoir size of smaller models would require too-frequent topping up or interruption of the work cycle. Its combination of high flow rate and large reservoir volume supports more productive operation in high-throughput hydraulic tooling environments.
