Hose Benefits & Features


The superior quality of DAE Open Flow Pumps is one key to our success but, more importantly, it is the key to your success in everyday applications. DAE Pumps is always engaged with customers to provide quality hoses for superior performance in the market.

To reach that objective, DAE Pumps invests in high-quality raw materials and in an engineered design to perfectly balance strength and elasticity. The result of this effort is the DAE Open Flow Pump portfolio, which adds premium performances and a life cycle up to 30% longer* than the competition.



  • Engineered designs with varying inner reinforcement layers (from 2 to 6) of braided polyamide are selected based on hose material and size.
  • The outer layer is vulcanized to strict tolerances to ensure perfect compression.
  • Best quality raw materials create an engineered compound to combine optimum mechanical and chemical characteristics.
  • External raw surface (hose is not re-machined after production) retains the lubrication film between the
    hose and shoe, reducing friction and heat generation to further extend hose life.
  • Available in 7 different material compounds and 16 different sizes to cover a wide range of applications and pump sizes.
  • Unique color code is located on the hose to facilitate the material identification.


  • Longer life: Up to 30% longer* than the competition due to the design features listed above.
  • Able to handle shear-sensitive fluids with minimal wear.
  • Highly versatile.
  • Available in different lengths retrofittable with most major competitive pumps.
  • Once retrofitted with DAE Open Flow Pumps, competitive pumps reduce their TCO (Total Cost of Ownership) thanks to an extended mean time between failures.


Low-pressure tubes are available for DAE Open Flow Pumps in different materials and with different levels of reinforcement. We can divide low-pressure tubes into two families:

  • Non-reinforced tubes – used mainly for very low-pressure transfer and dosing, can support fluid pressure up to 30 PSI.
  • Reinforced tubes – can support pressures up to 60 PSI and are more suitable for light industrial applications.


Get turnkey solutions that include dredge hoses, slurry flow meters, power units, and more. Choose from multiple sizes of slurry hoses for the transferring of materials, wireless flow meters for measuring the flow rate in gallons per minute of liquid, and power units for operation. Parts are always in stock and available for immediate shipping to anywhere in the US and the world.
