Erosion wear is recognized as an engineering problem in the slurry handling and transportation equipment. Centrifugal pumps are widely used in numerous industries for this purpose.Valves for Slurry Transport. The MOGAS tracking seat design results in the only true ... pumps, and choke systems, but the valve stations as well. The rate of flow, particulate size and ... particles could enter and quickly develop into severe erosion due to the high pressure of slurry transport applications.

Pipe abrasion and the associated erosion loss is a major concern in any slurry pipeline system. Efforts are constantly being made to improve pipeline structure and materials for a variety of industries. ... Hypothetically speaking, let's assume that a slurry pump and the pipeline have been configured to achieve a specific flow rate of a ...Slurry Pumps. For very harsh conditions where pumps are subjected to high erosion, we have a range of pump suitable for this environment such as mining, etc.

The paper discusses numerical prediction of erosion wear trends in centrifugal pump casing pumping dilute slurries. The casing geometry is considered two-dimensional. Discrete Phase Model (DPM) in FLUENT 6.1® is utilized to obtain dilute slurry flow field through the pump casing employing two-way coupling.Many types of pumps are used for pumping slurries, but the most common slurry pump is the centrifugal pump (pictured above). 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.

Commonly used pumps are slurry pump and centrifugal pump. Erosive particles are the agents which induce erosion, through the energy carried by the particles in the fluid. In order to achieve increase in concentration, some researchers have used a stirrer in their test set-up [ 34, 81, 98 ].The present slurry pump has improved erosion characteristics and comprises a rotatable impeller, an impeller shroud, and a pump housing. The rotatable impeller having at least one impeller vane and impeller shroud, and which has an inlet for conveying slurry to the impeller and an outlet for discharging slurry accelerated by the impeller.

Erosive wear mainly occurs on the impeller and casing of the slurry pumps due to the solid concentration and impact of the solid particles with a high velocity. For improved the performance...Erosion wear is an important factor in the design and operation of the equipment handling slurries. This paper outlines an energy approach to determine the erosion wear from the solids velocity and concentration distributions in the vicinity of the exposed walls.

– To design and fabricate a wear testing rig for a water pump impeller and to select a parameter that can be used to determine the wear rates of slurry pump impeller., – A wear equipment was designed and fabricated in this study that of main rotating shaft, supported by two ball bearings, and main electric motor bully mechanism for the rotational speed torque needed.In this work, three-dimensional (3D) unsteady numerical modeling of a centrifugal slurry pump with Eulerian–Lagrangian approach coupled to the erosion model has been performed to predict the erosive wear of the pump components namely, casing and impeller.

The developed version of this pump was the foundation for Denver's slurry pump programme for many decades and is still considered by many to be an industry standard.For proper design and selection of a slurry pump, extensive data are required for accurate estimation of the pump performance for the case of the slurry flow at high concentrations. Based on the present investigations, it is concluded that the relative wear along the casing is a function of the erosion behavior of the volute casing material and ...

persistent erosion problem. In addition to inflating maintenance costs, the erosion problem was negatively impacting unit throughput as a result of the slurry pump's rapid performance degra-dation. Manufactured by a large competitor of Flowserve, the 12% chrome pump was costing the plant approximately US$40 000 at each overhaul.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.

After long-term operation, the material loss due to slurry erosion often leads to significant changes in the impeller geometry. This change can, in turn, affect the flow characteristics and the erosion mechanism in a centrifugal pump.The HPX6000 high temperature process slurry pump is engineered for API 610 applications. This pump is a double walled pump where the outer casing manages the pressure and the internal liners are made from erosion resistant material that provides long life. The impeller is also made from the same erosion resistant material and is a true slurry design with repelling vanes in place of wear rings.

EHR series slurry pumps are similar to EHM series in structure. The main difference between EHM and EHR is the material of wet parts, which are natural rubber, chloroprene rubber or other wear-resistant rubbers. EHR are more suitable in delivering strong corrosive or abrasive slurries of small particle size without sharp edges.Diagnosis of wear patterns in centrifugal slurry pumps. In a mineral processing plant the slurry pumps are subject to wear due to erosion, abrasion and corrosion. This causes loss of material from the surface of the part. Eventually the pump will be unable to perform either due to holing of the casing or severe reduction in pumping head.

• Erosion resistance is greater where erosion is of a sliding bed type rather than one of directional impact • Has less erosion resistance to coarse sharp edged particles than natural rubber. Has greater erosion resistance to fi ne solids than natural rubber in some circumstances.Polyurethane slurry pump impeller spare parts speciallyThe Warman® SLR pump is designed for medium duty slurry handling duties where slurry conditions are less arduous and use of a heavy duty slurry pump cannot be justified.
