Project Background
During industrial production processes, large-flow and low-head circulating water transportation is a common requirement. A manufacturing enterprise planned to purchase a reliable vertical long shaft pump system because its existing equipment had low operating efficiency, frequent maintenance issues, and high energy consumption.
The site conditions were as follows:
Submerged depth: 3.75 meters
Medium: Industrial circulating cooling water
Required flow rate: 360 m³/h
Required head: 20.2 m
Power supply: 3 Phase / 400V / 50Hz
Installation type: Vertical installation
Operation requirement: Continuous operation
After analyzing the working conditions and communicating with the customer, we recommended the 200LC-23-37KW Vertical Long Shaft Pump solution.
