Slurry Pump Replace the Packing Seal for the Mechanical Seal

Slurry pump mechanical seal is the direct contact of the rotating ring and static ring. The sealing of rotating ring and static ring mainly rely on a very thin layer of liquid membrane between the two rings, which has a effect of equilibrium pressure and lubrication, cooling end face. In order to reach the fine seal effect, we need to keep the end face clean and smooth.

Through the transformation, it can improve the sealing performance of the pump, reduce leakage, save the amount of filler, reducing energy consumption, improve the mechanical efficiency, at the same time, it can also extend the operation cycle of the equipment, save the maintenance cost.

What is the Real Slurry Pump?

In the process of pump purchasing, users often ask about the service life of products. Strictly speaking, any manufacturer will not promise the accurate service life without any foundation. Because the service life of the flowing-passed components depend on various factors. 

At present the power plants in our country are mainly thermal power and hydro power. In the thermal power plant, through burning a large number of coal to generate power, the burned slag or ash need to be removed. At this time the slurry pump are used to clear the ash. So in the thermal power plant, the slurry pump is also used as ash pulp pump. In addition, because of the different working condition in the coal washing industry, the larger coal and coal gangue is easy to be blocked, the design demand for the slurry pump is very high. Though the slurry pump can be widely used in many fields, it is of great importance to use it correctly. Because of the name of the “slurry pump”, many people may have some misunderstanding. In fact, mud pump, trash pump, excavating pump, dredging pump are all in the application of the slurry pump. In the process of application of the slurry pump, we must pay attention to the reasonable design, the correct calculation and the right selection.

What Properties does Desulfurization Pump Have?

As we all know, desulfurization pump is a common industrial pump. But what properties does it have? Bojin pump, a specialized pump manufacturer, will introduce the main properties of the pump.

1. Desulfurization pump is good at resistance of corrosion and wearing and can be used to transport acid and alkali liquid.

2. Its pump body is steel lining UHMWPE structure and the lining thickness is 8-20mm. The pump adopts lining plastic patent technology, so compared with other industrial pumps, its lining layer has good resistance to heat, crazing and falling off.
3. Its impeller can be separate type or closed type, which can be chosen according to the media.
4. Sealing Methods: K type dynamic seal, K-1 type dynamic seal, T type packing seal, T-1 type packing seal, C3 type non-standard seal.

What Characteristics does KWPK Sewage Pump Have?

The KWPK-type sewage pump is stereo-type, single-stage and single-suction centrifugal sewage pump. What characteristics does the pump have?

1.As a kind of sewage pump, this type pump has excellent sewage capacity and it can transit solid particles whose diameter is between 30mm and 80mm.

2.KWPK sewage pump can tear fiber material by itself and then discharge them without filter screen.

3.With rational design and small-power motor, so its energy-saving effect is remarkable.

4. Sewage pump manufacturers use the high quality mechanical seals which makes the pump able to continuously work over 8000 hours safely.

5.Compact structure, convenient to move and simple installation can reduce project cost because it does not need to construct pumping stations.

In addition, KWPK-type sewage pump is suitable for conveying 80 °C fiber and other liquid suspensions, and not applicable to transporting acidic and alkaline sewage.

How is the working life of slurry pump?

Slurry pump is a kind of industrial pump which is widely used to transport slurry containing abrasive solid particles in mine, power sector, metallurgical industry, coal and mining industry, environmental protection and other industries. For example, ore pulp transportation in metallurgical mills, hydraulic ash handling in heat-engine plants, coal slurry transportation in coal washeries, dredging the waterway and so on. In chemical industry, slurry pump may be used to transport caustic slurry containing crystals.

As for the applications of slurry pump in concentrating mills, about 80% of them are used in mine industry. Due to the abominable working conditions, the working life of slurry pump is commonly short. However, different ores have different abradabilities. In the concentrate conveying section, abradability relatively decreases so the working life of pump is a little longer.
