Which hose for the pump? How to Choose, Factors, Materials, Sizes

Which hose for the pump?

A pump hose should be selected according to the type of pump and its specific operating conditions.  It is crucial to match the material, diameter, length and operating pressure of the hose to the requirements of the pump to ensure efficiency and durability.

Which hose for a submersible pump?

For a submersible pump, a hose made of PVC or rubber such as SBR, which is flexible and water resistant, will work best. In addition, the hose for a submersible pump should be of a suitable diameter usually 1 inch to ensure efficient water flow.

As for the length of the hose, it should be adapted to the submersion depth and the distance of water transport.

What hose for a deep well pump?

For a deep well pump, the best choice is a hose made of durable materials such as reinforced polyurethane, PVC, or synthetic rubber, which can withstand high pressures and extreme depths.  The hose should also be of appropriate length (often exceeding 10 meters) to reach from the well's depth to the discharge point.

What hose for a dirty water pump?

For a dirty water pump, a hose with high resistance to abrasion and chemicals is needed, such as a hose made from reinforced PVC or nitrile rubber.  The diameter of the hose should be suited to handle large volumes of water with contaminants, typically greater than 1 inch.

Regarding the length, the  hose should be appropriate for the working conditions, with some extra length to allow for easy maneuvering.

What hose to use for a russian pump?

The hose for a Russian pump should be durable and flexible.  Therefore, the best choice would be a hose made of reinforced PVC or EPDM rubber, which can withstand high pressures and intensive use.  The diameter should match the manufacturer's recommendations for the pump (usually 1 inch).

Why is it so important to choose the right pump hose?

Choosing the right pump hose is important because it affects the efficiency and safety of the whole system.  It is therefore worth understanding why this is so important before going into the details of hose selection.

Inefficient water flow

One of the main problems associated with improper hose selection is the restriction of water flow. In other words, an unsuitable hose can reduce the efficiency of the pump, resulting in longer operating times and increased energy consumption.

This is particularly problematic in systems requiring continuous and intensive water  flow, such as in the irrigation of large areas or in industrial systems, where inefficient flow leads to a significant decrease in efficiency.

Leakage

Another serious issue with improper water pump hose selection is the potential for leaks.  A low-quality or poorly fitted hose can quickly become damaged, leading to water loss and potential property or equipment damage.

In critical situations, such as fire suppression systems, a leak can have catastrophic consequences, preventing effective firefighting.

Premature wear

Using an unsuitable hose also accelerates the wear and tear of both the hose and the pump.  An improper hose material or construction can cause increased friction and mechanical stress, shortening the lifespan of both components.

This results in additional costs due to more frequent replacements and maintenance.

Safety hazards

In some cases, such as firefighting or handling chemicals, choosing the wrong hose can pose significant safety risks.  Hoses used in these applications must meet specific standards and be resistant to high pressures, temperatures, or aggressive chemicals.

Neglecting this aspect can lead to system failure at critical moments, endangering people and property.

What factors to consider when choosing a hose for a pump?

When selecting a hose for a pump, consider the following factors:

• material compatibility,
• hose diameter,
• hose length,
• pressure resistance,
• temperature range,
• flexibility and durability,
• type of reinforcement,
• fittings and connections,
• environmental conditions,
• budget.

Material compatibility

One of the most important aspects is the compatibility of the hose material with the pumped fluid. Different hoses are designed to handle specific substances, so it is crucial to choose one that will not chemically react with or degrade due to the liquid.

For example, for transferring chemicals, choose a hose resistant to chemicals.

Hose diameter

The diameter of the pump hose directly affects the water flow.  Generally, the wider the hose, the greater the flow.  However, matching the diameter to the pump's capacity is important.

Using a pump hose with a diameter that is too small will restrict the flow and reduce the system's efficiency, while a hose that is too large may not fit the pump outlet properly.

Hose length

When selecting the pump hose length, consider the distance between the water source and the pump, as well as between the pump and the discharge point.

The best pump hose will provide adequate reach without unnecessary excess.  If the hose is too long, it will reduce water pressure and pump efficiency, so it is important to find the right balance.

Pressure resistance

The pump hose should have a pressure resistance that matches the pump's output pressure.

Using a pump hose with lower strength than required by the pump increases the risk of failure or leaks.  Conversely, a hose with higher strength will be heavier and less flexible than necessary.

Temperature range

Consider the temperature of the pumped fluid and the surrounding environment when choosing a pump hose.

Hoses are designed to operate within specific temperature ranges, and using an unsuitable one can lead to damage or failure, especially in extreme conditions.

Flexibility and durability

Pump hose flexibility is important, especially if you need to maneuver around obstacles or work in tight spaces.  While a flexible hose is easier to handle, it is important to balance flexibility with durability.

If the hose is too flexible, it will wear out more quickly.  If it is too rigid, it will be difficult to manage.

Type of reinforcement

Pump hoses are reinforced with various materials such as polyester, nylon, or steel mesh.  This affects the hose's strength and its resistance to kinking under pressure.  Therefore, choose the appropriate level of reinforcement for the specific application requirements.

Fittings and connections

Fittings and Connections Ensure that the hose fittings are compatible with both the pump and the discharge point. This will prevent leaks and ensure that the system components are securely connected.

Consider using clamps or quick connectors for added security.

Environmental conditions

Evaluate the environmental conditions where the hose will be used.  Factors such as exposure to sunlight, UV radiation, abrasion, and contact with chemicals can negatively impact its durability.

Some hoses have protective coatings or are made from materials resistant to these conditions.

Budget

While it is important for the hose to meet all technical requirements, budget considerations should also be taken into account.  Hoses are available in a wide range of prices.

Although more expensive models typically offer greater durability, it is possible to find a hose that provides a balance between quality and cost.

What material will be best for a pump hose?

The best material for a pump hose depends on the type of fluid being pumped and the working conditions. For more common applications, PVC (polyvinyl chloride) hoses are most often used due to their flexibility, durability and resistance to chemicals. On the other hand, for applications requiring greater strength, such as pumping high-pressure water or corrosive substances, hoses made of EPDM rubber or reinforced polyurethane may be a better choice.

For specific needs such as the food industry, it is advisable to choose silicone hoses, which are resistant to high temperatures and meet hygiene standards.

What size will be best for a pump hose?

The best size for a pump hose is the one that will ensure the system runs efficiently and reliably. Below we discuss in detail how to choose the diameter and length of a hose for your pump.

What diameter should the pump hose be?

The pump hose should have a diameter that matches the pump's specifications. For example, if the pump has a capacity of 10 000 litres per hour, a suitable hose would be one with a diameter of 1 inch, as it will provide sufficient water throughput without excessive pressure loss. Using a narrower hose would restrict the flow of water, thus leading to a decrease in the pump's efficiency and increased run time.

However, it is important to always check the pump manufacturer's recommendation for the diameter of the hose, as different pump models may have different requirements in this respect.

How long should a pump hose be?

The hose for the pump should be long enough to transport the liquid from point A to point B without any problems. So, if the pump is used to draw water from a deep well to a reservoir on the surface, the length of the hose needs to be matched to the task.

For example, if the well is 10 metres below the surface, the hose length should be at least 12 metres to provide sufficient reach for connections and manoeuvring.

It is also worth bearing in mind that a hose that is too long can cause pressure drops, which will adversely affect the performance of the pump. Therefore, using a hose longer than the minimum necessary is not advisable.

Does the pump hose need to be certified?

Yes, the pump hose should have the relevant certifications. These confirm that the hose meets certain quality and safety standards, which is key to its reliability and durability.

Certified hoses are tested for pressure resistance, material strength and compliance with sanitary requirements (which is particularly important when pumping drinking water or chemicals). Choosing a certified product therefore ensures that it is suitable for a specific application and minimises the risk of failure or accidents.

What operating pressure must the pump hose be able to withstand?

The pump hose must withstand an operating pressure equal to the maximum output pressure of the pump to prevent damage and leakage.

For example, if the pump generates a pressure of 10 bar, the hose should be able to withstand this, and preferably have a small reserve (e.g. 12-15 bar) for additional safety. Remember, matching the working pressure of the hose to the pump is crucial for trouble-free and efficient operation of the entire system.

What temperature range should a pump hose have?

A pump hose should have a temperature range that matches the operating conditions and the type of fluid being pumped. General-purpose hoses usually cover a range from -20 °C to +60 °C. However, in specific applications such as the chemical or food industry, hoses sometimes have to withstand extreme temperatures (e.g. from -40 °C to +100 °C or more).

It is therefore important to select the hose appropriately for the working environment. This will avoid failures due to excessive heat or low temperatures.

What connectors should be chosen for a pump?

For your pump, you should choose couplings that ensure tightness, durability, and ease of installation. The best choice would be quick couplings such as CAMLOCK, GEKA or STORZ, which allow the hose to be connected and disconnected quickly and safely. These couplings are made of corrosion-resistant materials such as aluminium, brass, or stainless steel, guaranteeing a long service life.

It is also important that the couplings are compatible with the diameter of the hose and the pump outlet. Otherwise, there would be leaks, which would reduce the efficiency of the system.

How often should the pump hose be replaced?

The pump hose should be replaced regularly, according to the manufacturer's recommendations, and depending on the intensity of use and operating conditions. Normally, pump hoses operated under normal conditions may need to be replaced every 1-2 years.

However, if a hose shows signs of wear, such as cracks, leaks or loss of flexibility, it should be replaced immediately, regardless of the period of use.

Regular checks on the condition of the hose help to detect problems at an early stage, resulting in safe and efficient pump operation.

How to maintain a pump hose?

The pump hose should be cared for by regular cleaning, proper storage and regular inspection of its condition.  This is the only way to ensure its long service life and optimum performance.

Regular inspection

Periodically checking the condition of the hose is essential to identify early signs of wear, damage, or leaks.  This allows for the prompt detection and replacement of faulty components, preventing more serious issues and system failures.

Inspections should be conducted at least once a month, and more frequently if the hose is used intensively.

Cleaning

Regular cleaning helps remove dirt and deposits that can negatively impact the hose's integrity and water flow.

To clean the hose thoroughly, rinse it with clean water.  For more stubborn dirt, mild detergents can be used.  However, avoid using strong chemicals that could damage the hose material.

Storage

Proper storage is crucial for the hose's durability.  The best solution is to coil it in a way that prevents kinking and damage.

Hose reels are ideal for neat storage and easy access when needed.

It's also important to store hoses in a dry, cool place, away from direct sunlight and extreme temperatures, which can accelerate material aging.

Additional Tips

• Avoid Overloading - Do not exceed the hose's maximum working pressure to prevent damage.
• Use Proper Fittings - Ensure all fittings are properly matched and tightened to prevent leaks.
• Avoid Mechanical Damage - Do not drag the hose over sharp edges or rough surfaces that can cause damage.
• Seasonal Maintenance - Before winter, when hoses are typically less used, conduct a thorough inspection and maintenance to prepare them for storage.

Following these maintenance and care principles will ensure that your pump hose remains reliable and functional for a long time, minimizing the risk of system failures and costly repairs.
