Excavator Main Pump Suction Hose

Many original and aftermarket suction hoses fail easily on job sites-they collapse under suction, turn brittle in the sun, or leak after prolonged vibration. Our Excavator Main Pump Suction Hose is built to avoid these common issues, engineered exclusively for excavator hydraulic main pump oil intake. It keeps steady oil flow to the pump and protects your hydraulic system from unnecessary wear and breakdowns.

We adopt a solid three-layer construction tailored for construction field use. The inner rubber layer resists hydraulic oil erosion perfectly, never swelling or deteriorating from long-term fluid contact. The middle reinforced layer adds sturdy tensile strength, which stops the hose from deforming or collapsing when the pump is running. The outer rubber cover is thickened for outdoor use, holding up well against sunlight, oil stains and daily abrasion, so it won't crack or harden prematurely.

We have all common sizes to fit different excavator machines. Inner diameters from 50mm to 100mm cover small 5-ton units, standard 20-ton excavators and heavy-duty 30-ton+ models. Hose length follows the regular installation distance between the oil tank and main pump, with standard sizes ranging 20cm to 50cm, and custom lengths are available on request. It works flawlessly in extreme temperatures from -30℃ to +120℃, adapting to year-round outdoor construction environments.

Crafted as a practical field replacement part, our Excavator Main Pump Suction Hose fits almost all mainstream excavator brands used in global construction work. It matches the original installation interface completely, so you can install it directly without cutting or modifying any original pipelines. It is compatible with Komatsu, Caterpillar, Doosan, Hyundai, Kobelco, Sany, XCMG and Liugong excavators, covering most conventional models on the market.

This hose is core to the excavator's hydraulic oil supply system, delivering consistent hydraulic oil from the tank to the main pump for stable machine operation. It also works great for the suction lines of loaders, bulldozers and other heavy construction equipment, suitable for earthmoving, rock crushing, mining and all kinds of outdoor engineering work.

Construction working environments are always tough: constant machine vibration, long-term sun exposure, rain and snow, plus heavy dust and oil pollution. This suction hose is built to handle all these harsh conditions. It resists UV aging and mild acid-base corrosion, maintaining good flexibility and performance for a long time.

The reinforced structure effectively prevents the hose from being sucked flat, ensuring uninterrupted oil supply and eliminating pump abnormal noise, air suction and component abrasion caused by poor pipeline performance. Under normal construction operating conditions, it can serve reliably for 1 to 2 years without obvious aging damage, saving you frequent replacement costs and avoiding construction downtime caused by sudden hose failure.
