Discharge hoses used with submersible pumps are used to pump out water or wastewater. There are many hoses available on the market that differ in material, strength, and diameter. What parameters should be considered when choosing a hose for a submersible pump? Read on.
Material and operating temperature
When choosing a hose for a submersible pump, it is worth paying attention to the material it is made of and the temperatures at which it can be used. Most often, discharge hoses are made of durable PVC resistant to mechanical damage. PVC hoses for submersible pumps can operate at positive temperatures ranging from 1 to approximately 30–35°C.
Maximum operating pressure
Submersible pumps operate at different pressures. An important parameter when choosing a discharge hose for submersible pumps is the maximum operating pressure. This is particularly important in the case of hoses with the smallest diameters. The strength of the 1½-inch and larger discharge hoses available from Dambat is 4 bar. Hoses with smaller diameters have lower strength.
Diameter
Pump hoses are available in several diameters adapted to the type of pump. The smallest have a diameter of 25 mm, or 1”. Hoses with diameters of 1 ½”(40 mm), 2”(50 mm), 2 ½”(65 mm), and 3”(75 mm) are also available. Dambat offers discharge hoses in all these diameters.
Length
This is only seemingly a less important criterion. When choosing a hose for a submersible pump, we should know what length we need so that water or wastewater can be properly discharged from flooded rooms, wells, or excavations. The discharge hoses available from Dambat are sold in sections of at least 10 metres. The maximum length of a 1” hose roll is 50 linear metres. Rolls of hoses with larger diameters can be up to 100 linear metres.
Choosing the right hose for a submersible pump can be problematic, so it is worth consulting professionals before making a purchase. Dambat specialists are always happy to help match the right hose to any deep-well pump.
