GDL Vertical Inline Multistage Pump
Vertical Multistage Centrifugal Pump for High-Rise Water Supply & Pressure Boosting
GDL vertical inline multistage pump is a high-head centrifugal pump designed for high-rise water supply, pressure boosting, boiler systems, HVAC circulation and industrial water services. The vertical inline configuration allows direct pipeline installation while reducing floor space, and the multistage hydraulic design provides stable pressure for demanding water systems. GDL vertical inline multistage pumps are suitable for clean water and compatible liquids with properties similar to water. ZLZB® supplies GDL vertical multistage pumps with model selection based on required flow, head, liquid temperature, pipeline size and application requirements.
Flow Range:
2–160 m³/h
Head Range:
24–220 m
Power Range:
1.1–110 kW
Summary
GDL vertical inline multistage pump is designed for pipeline-mounted pressure boosting where installation space and piping layout are important. The suction and discharge connections are arranged inline, allowing the pump to be integrated directly into building and industrial water pipelines without a large floor footprint. Its multistage hydraulic structure provides the head required for high-rise water supply, booster systems, HVAC circulation, boiler water service and other pressurized clean-water applications. ZLZB® supplies GDL pumps for new installations and system upgrades, with model selection based on required flow, head, pipeline size, liquid temperature and operating conditions.
