Acid and alkali resistant pump - LDD Series
TIME：2024-01-10 Author：admin Views：
TYPICAL APPLICATIONS
● Chemical industry, chemical raw material storage plant, chemical tanker transportation industry,
● Environmental protection company, wastewater treatment plant, exhaust gas treatment tower.
● Chemical machinery manufacturing, electroplating filter manufacturing plant, electroplating plant, electrolysis plant, food plant, water plant.
● Nuclear power plants, petrochemical industry, steel mills, power plants, automotive industry, freezer cycle equipment.PRODUCT FEATURES
● Specially designed cooling for shaft seal. The built-in Teflon bellow seal features automatic cooling performance without use of circulated cooling hose.
● Vacuum self priming design. Extremely powerful self priming force. Built with a choke valve fully prevents liquid back-flow in the pump.
● Superior corrosion-resistant performance. Material - CFRPP.
● Rear Cover, seal cover and base frame are one-piece injected without welding. Therefore, it makes repairing, assembling, and disassembling easier.
● To prevent foreign matter from suction, foot valve should be installed in the inlet. To prevent from immediate backflow, check valve should be installed in the outlet. Backflow results in pump’s body damage and dry-running also damages to the pump.
