English Translation of Title:
Hydraulic Hose – Suction/Return, 20 mm, for Water Jet Cutting Machine Parts, Model No. 49891633-Hydraulic-Hose-SuctionReturn-20.1303.3-1

Introduction, Application, Features, and Maintenance:

This component is a hydraulic hose designed for suction or return line applications in water jet cutting systems. It is a flexible, reinforced hose with a nominal size of 20 mm, used to convey hydraulic fluid from the reservoir to the pump (suction) or from the system back to the reservoir (return).

Application:
Used in the hydraulic circuit of water jet cutting machines to carry low‑pressure hydraulic fluid. Typical installations include suction lines between the hydraulic tank and pump inlet, and return lines from valves, actuators, or motors back to the reservoir.

Features:

• Designed for low‑pressure suction and return line applications (typically < 10 bar / 145 psi).

• Nominal size: 20 mm.

• Flexible construction allows easy routing around machine components.

• Reinforced construction prevents collapse under suction and resists bursting under return pressure.

• Manufactured from oil‑ and abrasion‑resistant materials for long service life.

• Compatible with standard barbed, crimped, or push‑on fittings.

Maintenance:

• Regularly inspect the hose for signs of abrasion, cuts, bulging, cracking, or softening.

• Check connections for leaks or loosening during machine operation.

• Inspect for kinking or sharp bends that may restrict flow or damage the hose.

• Replace the hose immediately if any damage, wear, or leakage is observed.

• Ensure proper routing and support to prevent excessive vibration or chafing.

• Replace hoses at recommended intervals based on operating hours and fluid type.
