How to choose the right size of discharge or suction hose?

Ensuring you have the right size of your layflat discharge or suction hose is critical for your application. If the size is too small, flow rate will decrease, leading to inefficient performance. Here are several important factors to consider to avoid such issues:

 Determine the Application:

Different fluids have different viscosity, or in other words how sticky or runny a fluid is. Water for example, has a very low viscosity, while a substance like sludge or slurry has a very high viscosity meaning a higher friction loss and lower flow rate. With substances like slurry, you typically need a larger diameter of hose to be able to compensate for the friction loss. This is important to consider when choosing the sizes of your discharge and suction hoses. A friction loss calculator can assist in determining how much loss will happen with the substance you are conveying through the hose. 

Determine Desired Length of the Hose:

Another important factor is the length of your hose. The longer the hose, the greater the friction loss. To compensate for this you might need a larger diameter hose. 

Evaluate Size of Water Pump:

The third step is evaluating the size of the water pump and pressure ratings for your hose. The hose diameter should be equal to or greater than the pump outlet. With this also keep in mind to operate under the proper pressure ratings—every hose should with specifications on the outside. 

Understand Flow Rate Requirements:

Our fourth step is to understand the flow rate requirements. Higher flow rates will require a larger diameter to prevent excessive pressure loss and ensure efficient flow.  A flow rate calculator can help you determine the right size hose for your application. 

Evaluate Flexibility:

The last and final step is evaluating the flexibility and ease of handling. The larger the hose the more difficult it is to handle, and the more expensive it is, which could influence your decision on whether or not to make a purchase.

Closing:

Having the right size of hose can significantly impact the success of your project. It will allow you to transfer fluids more efficiently and quickly.
