Hoses serve as vital tools for transporting liquids in pump systems, regulating pressure, reducing friction, and preventing leaks. As such, the choice of hose directly impacts the operational efficiency of the pump. An incorrect hose selection can restrict water flow, increase the pump’s workload, or even damage the equipment. Therefore, choosing the right hose is essential.

How to Choose the Right Hose

Focusing on PVC Hoses

PVC hoses are widely used due to their affordability, lightweight, and versatility. The three common types of PVC hoses include PVC wire-reinforced hoses, PVC suction hoses, and PVC layflat hoses, each with its own advantages.

• PVC Wire-Reinforced Hose: High strength, excellent flexibility, and corrosion resistance, suitable for high-pressure environments, commonly used in industrial and agricultural applications.
• PVC Suction Hose: Designed for negative pressure environments, offering strong abrasion and pressure resistance, widely applied in agriculture, mining, construction, and industry for sucking or discharging water, mud, and other liquids.
• PVC Layflat Hose: Lightweight, flexible, and easy to roll up, ideal for agricultural irrigation, firefighting, and temporary drainage operations in construction.

Selecting Hoses Based on Application

For residential water supply and garden irrigation, lightweight and flexible PVC layflat hoses are ideal, allowing for easy handling and storage with simple installation. PVC wire-reinforced hoses or suction hoses are better suited for agricultural irrigation, providing good pressure resistance and durability for long-distance water transport across complex terrains.

In industrial drainage and wastewater treatment, it is crucial to choose PVC wire-reinforced hoses that are corrosion-resistant and high-pressure rated, suitable for transporting corrosive liquids and solid particles in demanding conditions. For construction sites or firefighting scenarios, PVC layflat hoses are a more fitting choice, as they are lightweight and easy to deploy for temporary water transport or emergency drainage.

Hose Maintenance and Optimization

When installing hoses, ensure that they are free from bends or twists to allow for smooth water flow, and check that the connections are tight to prevent leaks. Regular inspections of PVC wire-reinforced hoses and suction hoses are necessary to monitor their pressure resistance and prevent excessive aging.

Routine cleaning of the inner walls is essential to prevent sediment buildup, thereby extending the hose’s lifespan. Since PVC hoses can deteriorate more quickly when exposed to sunlight, it is advisable to store them out of direct sunlight.

During use, selecting hoses with the appropriate size and material can reduce the burden on the pump and enhance efficiency. Particularly in high-flow situations, using hoses with larger diameters can minimize frictional resistance and improve pump performance.

Common Hose Selection Mistakes

Using standard PVC hoses in negative pressure environments can lead to collapsing and rupturing, so it is essential to choose the right type of hose that matches its material to the intended application. Avoid focusing solely on low prices; cheaper hoses may lead to higher long-term maintenance costs. Opting for high-quality, reliable hoses is crucial for ensuring system safety.

In industrial or agricultural settings, durable, high-quality hoses can significantly reduce downtime and equipment wear, thereby greatly improving operational efficiency.
