2.2 Vertical slurry pump Feature

Pumps are vertical, centrifugal slurry pumps submerged in sump to work. They are designed for delivering abrasive, large particle and high density slurries. These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties. 
Wet parts of type NP-SP pump are made of abrasion-resistant metal. 
All parts of type NP-SP(R) pump immersed in liquid are lined with rubber outer liner. They are suited to transport non-edge angle abrasive slurry. 

2.3 Typical Applications---

Sump drainage washdown
Floor drainage
Mill sumps
Carbon transfer
Monitoring
Magnetite mixing

3.2 Sand Gravel Pump Feature

Naipu® Sand gravel slurry pumps are designed to handle very large particles for gravel and dredging operations. Naipu dredge and gravel slurry pumps are designed for the continuous handling of the most difficult higher abrasive slurries, containing solids too large to be pumped by a standard slurry pump. 
They are suitable for delivering slurries in Mining, explosive-sludge in metal melting, dredging in dredger and course of rivers and other fields. 
1. Construction of this pump is of single casing connected by means of clamp bands and wide wet passage. 
2. The wet-parts are made of Ni-hard and high chromium abrasion-resistance alloys. 
3. The discharge direction of pump can be oriented in any direction of 360°. 
4. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and Abrasion-resistance

3.3Typical Applications---

Slag Granulation
Suction Hopper Dredging
Dredging
Barge Loading
Sand Reclamation
Sugar Beet
 

4. SUBMERSIBLE SLURRY DREDGING PUMP





4.1 Feature

Naipu® NP-ZJQ submersible Slurry motor pump is a kind of hydraulic mechanism which motor connects directly with pump. The pump adopts excellent material, advanced structure, and it is with wide flowing passage & strong delivery ability. The hydraulic parts are wear-resistant. The pump is yet completed with control unit. The pump set consists of main impeller and vice impeller. The main impeller is used for absorbing and delivering solid-liquid mixture, the vice impeller is used for spraying or stirring solid-liquid mixture to help the impeller delivering. 

Compare with common mud pumps and slurry pumps, ZJQ series slurry pumps enjoy the characteristics as follows: 
1. Submersible Work without influence of suction head. 
2. No assistant vacuum pump, save your investment. 
3. No noise, keep the silence of your work station. 
4. With agitator, no need extra stirring devices, more convenience for operating. 
5. It do not need to build pump house
6. Directly works on the surface of the slurry, with more efficiency to delivery slurry

4.3 Typical Applications---

Delivering Liquid Sand, Coal Cinder Solid
Clearing The Mud In Lake, River, Sea
Drging Widening Channel
