DF-82
HEE
As a critical fitting for pump suction piping systems, this steel suction bellmouth solves common pain points including inlet vortex, flow loss, pump cavitation, and pipeline vibration, delivering stable and efficient fluid guidance for demanding industrial and marine working conditions. Manufactured with premium heavy-duty steel, the DF-82 series offers standardized sizing, universal compatibility, and long-term durability, making it the preferred choice for engineering contractors, shipyards, and industrial facility operators worldwide.
Model No. | ΦA | B | ΦC | D | E | F | G | Weight (lbs) |
DF-82-6 | 20" | 16 7/8" | 6 1/16" | 5/16" | 4 13/16" | 2 1/2" | 1/4" | 34 |
DF-82-8 | 20" | 16 7/8" | 8 1/16" | 5/16" | 5 3/8" | 3" | 1/4" | 34 |

The streamlined bellmouth profile of this industrial suction bellmouth for piping systems eliminates inlet turbulence and vortex formation, reducing pressure loss by up to 30% compared to standard flat-end pipe inlets, and significantly improving pump operating efficiency.
Fabricated from high-grade structural steel, the marine steel suction bellmouth offers exceptional impact resistance, corrosion resistance, and load-bearing capacity, adapting to harsh marine salt spray, industrial corrosive media, and long-term continuous operation.
The DF-82 series features industry-standard sizing, compatible with 6" to 10" nominal diameter suction pipelines, enabling direct retrofitting for existing systems without additional modification, reducing installation and engineering costs.
By stabilizing fluid flow and reducing inlet pressure fluctuations, this anti-cavitation steel suction bellmouth effectively prevents pump cavitation, extends pump service life, and reduces pipeline noise and vibration, lowering long-term maintenance and replacement costs.
The Steel Suction Bellmouth is installed at the inlet end of a pump suction pipeline. Its flared, streamlined bellmouth structure creates a smooth flow path for fluid entering the pipeline, eliminating sharp flow direction changes that cause turbulence and vortex. This design ensures uniform fluid velocity distribution at the pump inlet, reduces local pressure loss, and avoids the low-pressure zones that cause cavitation. By stabilizing the inlet flow state, the bellmouth maximizes pump hydraulic efficiency, reduces mechanical wear on pump components, and ensures stable, long-term operation of the entire fluid transfer system.
Before installation, verify that the model and inner diameter of the steel suction bellmouth match the connected pipeline, and check the weld surface for cracks, deformation, or defects that may affect sealing and structural integrity.
Ensure coaxial alignment between the bellmouth and the suction pipeline during welding installation, avoid eccentric installation that causes flow bias. The bellmouth should be installed vertically or horizontally according to system design, with sufficient submergence depth for underwater applications to prevent vortex air entrainment.
Perform regular visual inspections for corrosion, wear, and deformation every 6 months. For marine applications, apply anti-corrosion coating periodically to maintain structural integrity and hydraulic performance.
The DF-82 series is designed for 6", 8", and 10" nominal diameter suction pipelines, with corresponding models DF-82-6, DF-82-8, and DF-82-10 to match each pipe size.
It is widely used in marine ballast systems, municipal water supply and drainage, industrial fluid transfer, water conservancy projects, fire protection systems, and other scenarios requiring stable pump suction performance.
Yes, we offer custom services including material upgrades, size adjustment, and anti-corrosion treatment modifications to meet specific project and industry standards.
