DLB is a kind of vertical non-self priming multistage centrifugal pump, which is driven by a standard electric motor.
The motor output shaft directly connects with the pump shaft through a coupling. The pressure-resistant cylinder and flow passage components are fixed between pump head and in-and outlet section with tie-bar bolts.
The inlet and outlet are located at the pump bottom at the same plane.
Operation conditions:
1. Thin, clean, on-flammable and non-explosive liquid containing no solid granules and fibers.
2. Liquid temperature: Normal temperature type: -15° C~+70° C Hot water type: +70° C~+120° C
3. Ambient temperature: Up to +40° C
4. Altitude: Up to 1000m

Feature
Stable in operation: Absolute concentric of pump shaft, excellent static and dynamic balance of impeller, Smooth running, no vibration.
Watertight: Hard alloy seal with different materials, Ensure that the different medium conveying without leakage.
Low noise: Water pump supported by two low noise bearings contributes to stable operation without noise basically except slight sound of motor.
Low failure rate: The structure is simple and reasonable, the key parts adopt the international first-class assort, the whole machine work time.
Convenient in maintenance: It's convenient and easy to replace the seal and bearing
More space effective: The outlet is available for three direction, leftwards, rightwards and upwards, easy for pipeline layout and installation and space-effective.
