East Dfw Horizontal Centrifugal Single-Stage Pump

Use of B35 - mounted Extended - Shaft Motor

Diversity of Mechanical Seals

• The shaft seals of DFW series horizontal centrifugal pumps adopt mechanical seals, which have small leakage and long service life. You can choose MG1 or 120 series mechanical seals, and select the material of mechanical seals according to the application scenarios.
• Materials for dynamic and static rings: Graphite, silicon carbide, tungsten carbide, aluminum oxide.
• Materials for auxiliary sealing elements: Nitrile rubber, fluororubber, ethylene - propylene rubber, silicone rubber, fully - coated FEP, fully - coated PFA.
• Materials for springs and other structural components: 06Cr17Ni12Mo2Ti(G), 06Cr19Ni10 (F), Hast.C4(2.4610) (M), X2CrNiMoN22 - 5 - 3 (G1).

Reinforcing Ribs in Pump Body Design

• Under normal wall - thickness conditions, reinforcing ribs are designed in the pump body. This increases the strength and rigidity of the pump body. Meanwhile, it can overcome the casting deformation caused by uneven stress due to the different structural forms and varying thicknesses in different parts of the pump body. As a result, it improves the quality of casting products and enhances the overall product quality.

High - Efficiency and Energy - Saving

• The product quality of DFW series horizontal centrifugal pumps complies with the standard GB/T5657 "Technical Conditions for Centrifugal Pumps (Class II)". It keeps improving on the original basis, applying the latest achievements in hydraulic research. Through the three - dimensional design theory and model - based performance analysis methods for pumps, it maximally expands the high - efficiency area of the pump and broadens the high - efficiency range.
  The hydraulic model of the impeller is perfectly matched with the flow passage of the pump body, improving the pump's efficiency. The uniquely designed hydraulic model of the impeller significantly enhances the overall operation efficiency of the pump, ensuring reliable operation under variable working conditions.
