Hoses and Nozzles: Temperature_Range -40°C to +120°C

Component Specifications

Definition

Hoses are flexible conduits designed to transport water under pressure from the pump to the point of application, while nozzles are precision-engineered attachments that control flow rate, spray pattern, and dispersion characteristics. These components work in tandem to ensure efficient fluid delivery with minimal pressure loss and optimal operational control in industrial water pump systems.

Working Principle

Hoses utilize their flexible structure to accommodate movement and vibration while maintaining a sealed pathway for pressurized fluid. Nozzles operate on fluid dynamics principles, converting pressure energy into controlled kinetic energy through precisely engineered orifices and internal geometries that determine spray angle, droplet size, and flow distribution.

Materials

Hoses: Reinforced synthetic rubber (EPDM, NBR), thermoplastic polymers (PVC, polyurethane), stainless steel braiding. Nozzles: Brass, stainless steel (304/316), engineered plastics (PTFE, polyacetal), ceramic inserts for abrasive applications.
