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 |
| Depending on where the bearing support is | ● Overhung ● Between-bearing | ● Overhung |
| Depending on shaft orientation | ● Horizontal ● Vertical | ● Horizontal ● Vertical |
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%).
