ZGB series slurry pump: modern CAD design, excellent hydraulic performance, high efficiency, low wear rate, large flow rate, multi - span, multi - stage series, mainly used for power, metallurgy, mining conveying corrosive slurry, Especially used in power plant ash.

 

In mining operations, slurry pumps are used to transport the target minerals and overburden to plants which use a system of wet separation. After crushing and screening, the mineral is usually milled before being transported for further separation. This process requires a large volume of slurry to be transported across often long distances. Once this process is complete, the tailings are usually disposed of via piping systems to the tailings dumping site.

 

Special designs are also available for handling froth in the separation process.

Slurry pump selection is a complex process and requires close cooperation between the pump manufacturer and the end user as the medium to be pumped and the pump operating conditions are extremely important to the correct pump selection.

This article will outline the basic principles involved in selecting the right pump for the job, and will look predominantly at centrifugal slurry pumps.

2.The highest feeing pressure could be 2.5Mpa, the rate pressure is 2.0Mpa, the pressure could be adjusted.3. Pistons are made of alumina ceramics,of great abrasion resistance and corrosion resistance

4. Using combined seal, good sealing efficiency

5.Good Design Structure, Convenient Installation and maintenance, Long Usage Life Span

 

Centrifugal slurry pumps

Fengwang-Centrifugal slurry pumps are typically used in mineral extraction process plants, and are designed to handle abrasive solids mixed with a carrier fluid.

Slurry pumps often operate 24/7, and in severe conditions the wear life of wetted components can be up to two to three months.

Since excessive wear would be generated on the inter-stage passages of a multi-stage slurry pump, they are invariably single-stage equipment.

Both horizontal and vertical shaft configurations are available, with transmission of process slurries around a plant usually handled by horizontal pumps, while vertical pumps are used in sumps and generally have a cantilevered shaft so that all bearings are located above fluid level.

 

Slurry pump selection

Slurries are often very abrasive and may contain large solid particles. This makes wear life and the ability to pass these large solids key considerations in pump design and application.

Wear can be controlled by proper pump selection based on the application details provided by the user, and is related to the velocity between the pumped slurry and the pump. For pumps in more severe services to have a satisfactory life, liquid velocities should be reduced.

Experience has shown that the impeller rotational speed should be kept as low as possible for pumps handling abrasive fluids. Wear will vary approximately as the cube of the speed and with particle concentration.

Rubber-lined pumps are limited to lower impeller peripheral speeds because pressure fluctuations from the passing impeller vanes may cause internal heating due to the deformation hysteresis of the rubber. Increasing pressure fluctuations would eventually lead to degradation of the rubber polymer structure.

When operating conditions or other considerations require longer component life, the peripheral speeds should be lowered, noting that wear life would be approximately doubled by a 20 per cent drop in pump rotational speed.

Even the largest, most robust pump running at slow speed may still experience gouging and wear. Where the pump is running compared to its design best efficiency point (BEP) is important. Acceptable gouge-free wear depends, among other factors, on the actual percentage of BEP flow rates experienced during operation, with 100 per cent BEP being the optimum.

Fengwang AH series slurry pump is horizontal, vertical open type, double pump shell structure.Wide performance, good cavitation, long service life, high operating efficiency, mainly suitable for conveying strong corrosion, high concentration of slag slurry or low density, low corrosion of high lift slurry.

 

slurry pump types

Horizontal slurry pumps

Horizontal slurry pumps are applied in various slurry transport applications.

With wear parts in either hard metal or rubber, horizontal slurry pumps are often larger, more powerful and offer higher capacity than vertical slurry pumps.

Vertical slurry pumps

Vertical slurry pumps are highly configurable pumping equipment designed to reduce maintenance and operating costs.

They require less floorspace than horizontal pumps and wear parts are available in hard metal or rubber.

 

SLURRY PUMP SELECTION

Selecting the right pump for slurries is critical to get the most bang for your buck. Basic pump components, such as the impeller size and design, material of construction, and discharge configurations must be considered to ensure the pump will hold up against the wear caused by an abrasive slurry. Slurry pumps are generally larger in size when compared to low-viscosity liquid pumps and usually require more horsepower to operate because they're less efficient. Bearings and shafts must be more rugged and rigid as well.

Many types of pumps are used for pumping slurries, but the most common slurry pump is the centrifugal pump. The centrifugal slurry pump uses the centrifugal force generated by a rotating impeller to impact kinetic energy to the slurry, similar to how a water-like liquid would move through a standard centrifugal pump.  

 

SLURRY PUMPING CONSIDERATIONS

If you have experience pumping slurries, you know it's not an easy task. Slurries are heavy and difficult to pump. They cause excessive wear on pumps and their components and are known to clog suction and discharge lines if not moving fast enough. Most importantly, it’s a challenge to make slurry pumps last for a reasonable amount of time. But, there are a few things you can do to extend the life of your slurry pump and make pumping slurry less of a challenge.

Find the sweet spot that allows the pump to run as slow as possible (to reduce wear), but fast enough to keep solids from settling and clogging the lines

To reduce wear, lower the pump’s discharge pressure to the lowest point possible

Follow proper piping principles to ensure a constant and uniform delivery of the slurry to the pump

Pumping slurries poses several challenges and problems, but with proper engineering and equipment selection you can experience many years of worry-free operation. It's important to work with a qualified engineer when selecting a slurry pump because slurries can wreak havoc on a pump if not properly selected.

What is a slurry pump?

A slurry pump is a centrifugal type, specifically designed for hydraulic conveyancing of abrasive and often corrosive solid particles within a carrier fluid. The slurry pump should be of a low specific speed design, allowing slower operating speeds than conventional water pumps in order to reduce the velocity of the solid particles and thereby reducing wear rates. Slurry pump components that come in contact with the pumped medium are manufactured from wear resistant metallic or elastomeric materials, selected to suit each particular application.

In harsh conditions with sand, sludge, rocks, slurry, normal dredge pumps clog, wear and fail more often. This leads to downtime for maintenance, hurting your bottom line. Not the case with the Fengwang Pump, since we have the tolerance to pump objects up to 12 inches to ensure maximum uptime and production rates in any industry dealing with abrasives, solids, and high viscosity materials.
