Function Introduction:
In order to meet the requirement on the development mining, metallurgy, electric , mature experiences for many years on research& manufacture and application of slurry pump. meanwhile based on technology introduction. We development the new generation production with large capacity ,high head ,multi-stage mainly .the pumps of this type also may be installed in multistage series.
1. advanced hydraulic performance, CAD modern design , high efficiency and lower abrasion rate 2. wide passage, non-clogging and good performance of NPSH .3. expeller seal combined with packing seal and mechanical seal have be adopted to guarantee the slurry from leakage.4. the reliability design ensures long MTBF(mean time between events)5. the metric bearing with oil lubrication, reasonable lubricating and cooling systems ensure the bearing to be operated under the lower temperature.
6.the materials of wet parts had the good performance of anti-wearing and anti-corrosion, the pump can be used for seawater ash-removing to prevent it from the corrosion of sweater, salt and mist ,and electrochemical corrosion.
7.the pump can be operated in series with multi-stage within permissible pressure . the permissible maximum working pressure is 3.6 Mpa .
The series of pump has the advantage of reasonable construction , high efficiency, reliable operation and easy maintenance. It can be widely used for handling the mixture contained of abrasive and corrosive solids in electric power, metallurgy ,mine, coal, constructional material and chemical industry departments especial for removing ash and sludge in electric power station.
Pump Features:
1. The series ZGB(P) slurry pump is of horizontal, single-stage, single-suction, cantilever, double-casing, centrifugal slurry pump. The pump rotates in clockwise viewed from the drive end.
2. The wet parts of ZGB and ZGBP pump at the same outlet diameter can be interchangeable. Their outline installation dimensions are one and the same. For the drive part of the series ZGB(P) slurry pump, the horizontal split frame with oil lubrication and two sets of water cooling systems inside and outside has been adopted. If necessary, cooling water can be supplied. The prepared joint for cooling water and the pressure of the cooling water can be seen in table 1.
3. Two kinds of shaft seal-expeller seal combined with packing and mechanical seal have been used for series ZGB(P) slurry pump.
4. The mechanical seal supplied with high pressure sealing water is recommended when the slurry pump is operated in series(two stages and above two stages), and the expeller seal combined with packing is used in single-stage pump.

Introduction of Centrifugal Slurry Pump :
1. Abrasion and corrosion resisting
2. Material: hard alloy metal(Cr27,Cr28, Cr30, CD4MCu) or rubber liner optional,
3. Shaft seal: packing seal, expeller seal, and mechanical seal.
4. Power driver: electrical motor or diesel engine.
Application of Centrifugal Slurry Pump :
Deliver slurry with hard particle, in the mining, metallurgy, coal washing, power plant, sewage water treatment, dredging, and chemical and petroleum industries
1. Conveying mortar,slag which are strong corrosive and with solid particles.
2. Widely used in extracting sand, marine reclamation land,power plant,mining.
Features of Centrifugal Slurry Pump :
- Multi-purpose sand and gravel pump, high efficiency and energy saving.
2. Horizontal, centrifugal, one stage, single casing slurry pump.
3. Distinctive innovation in hydraulic and structural design.
4. Pump discharge direction can be changed in any 45 degree,easy installation.
5. Long-term bearing life: The bearing assembly is composed of large diameter shaft
and short overhang.
Component of Centrifugal Slurry Pump:
1. All of the metal wet parts can are made of high chromium alloy which has superior wear and erosion resistance or grey iron which has a high rigidity.
2. As the expeller ring is assembled together with the expeller, much pressure can be reduced effectively for the impeller. Meanwhile, it can still maintain a reliable sealing performance.
3. The parts such as labyrinth, labyrinth lock nut, end cover and shaft sleeve are used for bearing assembly; these parts can be changed easily and have high accuracy and longer service life.
4. Some fastening parts such as studs and bolts can be used for fixing the other parts securely. All the fastening parts can be attached easily, ensuring the safety.
- All of the rubber parts have superior erosion resisting performance which can be used for a long life.
Drive type of Centrifugal Slurry Pump:
DC Type: The output shaft of a motor is directly connected to the input shaft of a pump via a pump coupler. This type of connection is suitable for applications where the speed of the slurry pump is the same as that of the motor.
CV Type: The pump is driven by a belt connected to the crankshaft of the engine. This way of connection allows for saving space, easy installation, and fast adjustment of pumping speed. The motor is fixed to the motor support frame which is located on the bearing support above the slurry pump.
ZV Type: Another type of belt drive that allows easy adjustment of pumping speed. The motor is directly fixed to the bearing support. This way of installation is suitable for motors with larger horsepower than is possible with CV type of installation. Due to the installation of motor onto the bearing support, this method helps save installation space.
CR Type: This type of belt drive makes it easier to adjust pumping speed. The installation allows both the motor and slurry pump to be fixed to the ground. The motor is installed to the side of the pump. This installation method is suitable for large-power motors
