Drawing upon years of manufacturing experience and utilizing specialized hydraulic and structural designs, our company has developed this vertical multistage fire-fighting pump. Its flow and pressure ratings make it more suitable for building fire-suppression water supply systems than standard centrifugal clean-water pumps, and it features a flat flow-pressure characteristic curve free of "humps."
| Flow rate range | 1-40L/s |
| Power range | 0.75~160kW |
| Head range | 30~200m |
| Rated speed | 2900r/min, 2850r/min |
· When viewed from the motor end, the GDL-type vertical multistage fire pump rotates in a clockwise direction.
· The impeller utilizes a hydraulic balancing method to counteract axial forces; a guide bearing is located at the lower end of the pump, and the shaft is connected to the motor shaft via a clamp-type coupling for power transmission, while the outer casing is made of stainless steel.
· It features a vertical, multistage, segmental structure; the inlet and outlet flanges lie on the same horizontal axis and share the same nominal diameter, facilitating pipeline connection and making installation and removal extremely convenient.
· There is no need to dismantle the piping; simply remove the pump cover nuts to extract the motor and drive assembly for maintenance.
· The shaft seal utilizes a cemented carbide mechanical seal, ensuring zero leakage and no shaft wear, thereby maintaining a clean working environment.
· The impeller and rotating friction components are made of alloy; they are corrosion-resistant and rust-proof, preventing the formation of rusty water that could clog fire-fighting equipment such as sprinklers, thereby extending service life.
