■Advanced hydraulic models of high efficiency and better performance.

■Only 2900 rpm is available,the dimension is smaller compared to old DL series which speed is 1450 rpm. Therefore,it takes smaller space and saves cost in construction.

■Compact structure,can be installed outdoor with shelter.

■Special mechanical seal with advantage of easy maintenance.

■Various materials for different temperature and pressure.

■Vertical,multistage and sectional structure. The inlet section,middle section and outlet section are tightly connected by bolts.

■One impeller+a guide vane for every stage,the axial force is hydraulically balanced,the bearings bear the rest axial force.

■During the maintenance,the mechanical seal can be removed out by dismantle the clam couplings in the middle,no need to dismantle motor.

■Pump inlet is at the bottom of casing,while pump outlet is at the top of casing. The relative angle of pump inlet and outlet can be customized as 0°, 90°, 180°, 270°.
