The 4I-1023 is a hydraulic gear pump designed for the CAT E320 excavator, delivering consistent flow under high-pressure conditions typical of heavy-duty construction equipment. This model is engineered to match OEM specifications for displacement, pressure rating, and mounting interface, ensuring direct compatibility with the E320’s hydraulic system without modification. The pump operates within standard hydraulic oil viscosity ranges and is built to handle the cyclic load demands of excavator boom and arm circuits.
Constructed from high-strength steel alloys typical for hydraulic components, the 4I-1023 features precision-machined gears and a hardened housing to resist wear from abrasive particles in hydraulic fluid. Standard seals and bearings meet or exceed OEM durability benchmarks, while the unit’s design allows for in-line or side mounting configurations common to CAT hydraulic circuits. The pump’s typical operating temperature range spans -20°C to 90°C, with a maximum intermittent pressure of 250 bar.
Primary buyers include equipment owners and repair shops servicing CAT E320 units in mining, earthmoving, and infrastructure projects. The pump is supplied as a direct replacement part, with the supplier confirming fitment for the specified model. Buyers should verify the exact part number against their machine’s serial to ensure compatibility, as CAT hydraulic systems may vary by production year. Bulk orders are packed in reinforced crates to prevent damage during transit.

Before ordering, verify the exact part number 4I-1023 against your CAT E320’s serial number and hydraulic system diagram to ensure compatibility. Cross-check the pump’s displacement and pressure ratings with your machine’s requirements, as variations may exist between production batches. Request a copy of the supplier’s test reports or OEM cross-reference documentation to confirm fitment.
Confirm the Incoterms offered by A&S Construction Machinery Co., Ltd., as these will determine your responsibility for shipping, insurance, and customs clearance. Lead times for hydraulic pumps can vary, so request an estimated delivery schedule and packaging details to avoid transit damage. Payment terms should be agreed in advance, with preference for secure methods like letters of credit for high-value orders.
Insist on a pre-shipment inspection to verify the pump’s condition, including gear wear, seal integrity, and pressure testing at the rated 250 bar. Request a material test report for the housing and gears to confirm they meet OEM standards. Ensure the supplier provides a bill of lading, commercial invoice, and packing list, along with any required certificates for customs clearance in your country.
