Basic structure

Impeller:
This double suction pump uses a double-suction design with two inlets. Liquid flows into the impeller from both sides at the same time. Compared to single-suction pumps, this design balances axial force well, reduces wear on the bearings, and makes the pump last longer. The impeller's shape and size are carefully worked out to make sure liquid is moved efficiently.
Shaft seal device:
Large flow industrial circulation double suction pump have two common types of shaft seals: mechanical seals and packing seals. Mechanical seals have advantages like small leakage and long service life, making them suitable for occasions with high sealing requirements. Packing seals, on the other hand, have a simple structure and low cost, but their leakage is relatively larger and the packing needs regular replacement.

Performance characteristics

Large flow rate:
Large flow double suction pump can meet the demand for transporting large amounts of liquid in industrial circulation systems, with a flow range usually ranging from tens to thousands of cubic meters per hour. For example, in the circulating cooling water systems of large chemical enterprises, industrial circulation double suction pump can quickly transport the cooled water back to production equipment, ensuring the continuity of the production process.
High head:
It can lift liquids to a certain height, with the head usually ranging from several meters to dozens of meters, or even higher. In some industrial scenarios where liquids need to be transported to higher positions,such as fire water supply systems in high-rise buildings large flow double suction pump high head play an important role.
High efficiency:
Large flow industrial circulation double suction pump impeller and volute are designed to work optimally. This lets the pump turn mechanical energy into the liquid's pressure and movement energy efficiently when running. It cuts down on energy loss and makes energy use more effective.
