DVR Slurry Pump

1. Vertical cantilever single pump casing structure.
2. The double-suction semi-open impeller is designed with high chromium alloy, which can adjust the gap between the impeller and the rear guard plate to ensure the efficient operation of the pump.
3. No shaft seal required.
4. Direct connection or belt transmission can be used for transmission.
5. The rotating direction of the pump is clockwise from the driving end.

DVR slurry pump structure

DVR 3D Structure

The DVR submersible pump is a vertical centrifugal slurry pump, immersed in liquid, used to transport corrosive, coarse particles, and high-concentration slurries. It does not require any shaft seals or shaft seal water, and can work normally even under conditions of insufficient suction. The flow-through parts are all lined with rubber, suitable for conveying abrasive slurries without edges and corners. The "L" letter in the model is a submersible pump of the extended shaft series, which can be used in conditions with deeper liquid levels. This type of pump adds a guide bearing structure on the basis of the standard, which makes the operation more stable and more widely used. However, flushing water is required at the guide bearing position.
