DLF stainless steel multi-stage pump
Message If you want any further detail data and drawing,please contact us.
DLF stainless steel multi-stage pump is vertical structure.The pump mainly comprised by the vertical motor, motor base, coupling clip block, pump (including the pump shaft, impeller, diffuser, alloy bearings, etc.), outside the cylinder, base, bar etc.. Pump rotor shaft through the joint folder block from the direct-drive motor. Water pump axial force be solved by the force balance. Light multi-stage centrifugal pumps for transport of water, or physical and chemical properties similar to water and other liquids. Temperature ≤ 105 ° C.
The product's host part is welded by stainless steel metal forming, compared with the current domestic cast iron pumps, it has advantages of small size, light weight, high pump efficiency, low noise, little vibration, easy installation, beautiful appearance etc. . Bearing and Seal are made by high wear-resistant alloy material, so it have a long life, less maintenance characteristics and be a new energy-saving products in centuries.
