High Chrome Abrasive Slurry Transport Using Centrifugal Pumps
Submersible Sand Pump
Slurry Pump Principle
Slurry pumps are widely used in many industries because they can
convey pumping liquid containing solid particles, as well as
corrosive and abrasive slurry. They are more robust than other
ordinary centrifugal pumps, because they use sacrificial material
to resistent abrasion.
The working principle of the slurry pump is that the slurry enters
the pump through the rotating impeller, thereby the medium rotates
in the pump body. The slurry is forced to move outward under the
action of centrifugal force and move between the blades of the
impeller. The pump increases the pressure of the liquid and solid
particles by means of centrifugal force and converts the electrical
energy into kinetic energy to pump the slurry. In this way, slurry
pumps are able to transfer dangerous and lightweight slurries and
easy to maintain.
Slurry Pump Types
| Factors of Pump | Types of Slurry Pumps | Our Slurry Pump |
| Number of impellers | ● Single stage ● Two-stage ● Multi-stage | ● Single stage |
| Type of case-split | ● Axial split ● Radial split | Axial split |
| Type of impeller design | ● Single suction ● Double suction | ● Single suction |
| By type of volute | ● Single volute ● Double volute | ● Single volute |

Product Benifits
a) Wear parts are all constructed with abrasion resistant materials
- chromium alloy, so pumps have better stability & longer service
life.
b) Unique mechanical seal device can prevent the electric motor
from high pressure water and impurities, thus high suction
efficiency can be ensured.
c) Easy installation, operation and cost saving, since no
additional vacuum pump or pump house is needed.
d) In addition to the main impeller, a pair of agitation impeller
is equipped to help break and mix the sludge.
e) Professional technology support is provided during the whole
process of the usage and maintenance.

Applications
Slurry pumps are the most popular choice for transferring water,
sewage drainage and ore pulp are among the most common
applications.
Oil & Energy – To pump crude oil, slurry, mud used by refineries,
power generation plants
Waste Management Wastewater treatment – Wastewater processing
plants, municipal industry and drainage
Pharmaceutical, Chemical & Food Industries – paints, hydrocarbons,
petro-chemical, mining industry, cellulose, sugar refining, food
and beverage production
In mining, metallurgy, power, coal, chemicals, building materials
and other industries, ZJL-series vertical slurry pumps can be used
to transfer abrasive and corrosive slurry containing solid
particles (maximum density of solid-liquid mixture: for mortar,
45%; for pulp, 60%).

Installation Dimension
As our pumps are customized product, some information are needed
for us to choose the pump model. The following information is very
important and the most basic, please read it carefully.
1. Medium information:fluid, temperature, solid content, particle
size,viscosity, density, corrosion, Ph and so on.
2. Pump information:flow, head, NPSHr, motor power, voltage,
frequency and so on.
3. Any other requiremnets for the pump.
