Slurry pumps: technical characteristics, testimonials and photos

Slurry pumps are equipment with which you can pump slurry with a large content of soil, sand and sludge. If compared with faecal pumps, centrifugal slurry devices are capable of operating under extreme conditions, when the density of inclusions reaches 2500 kg / m 3 . At the heart of the flow-through part of products of this type are:

  • Armored disk;
  • Wheels;
  • Body.

Feedback on the principle of slurry pumps

Slurry pumps, according to customers, can be used for pumping media of different viscosities, they can contain impurities with solids, more about this you can read below. The principle of operation of devices of this type, as claimed by customers, is based on the displacement of sludge by a rotating shaft inside the stator.

The pumped mass is pumped along the axis of the pump by sealed chambers, they form a moving part. The volume of cavities and their number, according to buyers, affect the pressure produced. This equipment is characterized by a uniform flow. The device has a high level of suction.

Reviews about the field of use

Slurry pumps, according to customers, can be used in many areas of human activities. For example, in the mining and processing industry, this equipment pumps waste water, enrichment products, mining and transportation. In the conditions of metallurgical, rolling and steelmaking plants such devices:

  • Pumping gas slurries, sinter water, granulated slag;
  • Carry out dust removal:
  • Provide wet cleaning;
  • Transporting solid particles;
  • Carry out wet dust removal.

Slurry pumps, according to customers, excel at gravel production, where gravel and sand are prepared, as well as raw materials. According to consumers, such equipment is excellently suited for the production of sugar refineries, where it is necessary to prepare washing water, transporting liquids, sewage and the bleaching process is carried out. You can use these devices in the glass industry, oil refining and aluminum plants.

Reviews and specifications of horizontal slurry pumps

Slurry pumps can be horizontal. They are intended for large-solid solid products and aggressive slurries. They are characterized by high performance and reliability even under difficult operating conditions. Customers like that high-quality composite materials are used in the manufacture of such equipment, which form the basis of wear parts, and this is the key to the quality of such devices.

Among the technical characteristics should be allocated a feed that reaches 20,000 m 3 / h, as well as a head equal to 145 m or less. This equipment is developed on the basis of some principles, among them:

  • Maximum efficiency;
  • Low consumption;
  • power;
  • standardization;
  • Minimum wear;
  • Ease of maintenance.

Features and specifications of vertical slurry pumps

Vertical slurry pump can be classified into two types, among them:

  • Armor vertical;
  • Semisubmersible vertical.

The hydraulic part of the armored pumps is similar to the hydraulic part of the horizontal pumps. On sale you can find installations in dry and wet modifications. The supply is provided at a level of 3000 m 3 / h, while the maximum immersion depth is 5 m. The head reaches 145 m.

Submersible pump characteristics

Submersible slurry pump TOYO DPE provides feed up to 400 m 3 / h, the temperature of pumped medium can vary up to +60 ° C and up to 80 - on request. The pumped medium must have a pH between 4 and 9.5. The working depth of the dive reaches 30 m.

Description of pump ВШН-150

The aforementioned slurry pump 150 is a centrifugal vertical equipment which is used for pumping slurries with a solid fines. The density of the latter can reach 1300 kg / m 3 . Suspended particles can have a hardness of no more than 3 on the Mohs scale.

The size of individual elements can reach 20 mm, but no more than 20% of them can be contained in the volume. This centrifugal slurry pump is capable of pumping medium with a temperature in the range from +4 to +50 ° C. This device can be used to carry out auxiliary operations when pumping a washing solution.

Technical specifications ВШН-150

The feed rate is 150 m 3 / h, the head is 30 m. The efficiency of the pump is 57%, while the speed of the motor is 150 rpm. The capacity of the equipment is equivalent to 30 kW, the weight of the pump is 360 kg. The diameter of the inlet and outlet nozzles is 125 mm.

Description of the hydraulic pump Toyo

A hydraulic slurry pump of the aforementioned brand can have a power in the range of 11 to 124 kW. This equipment is characterized by high power, durability, performance and high torque. The device is single-stage, can have a reinforced design. It is hermetically sealed, corrosion-resistant and armored.

The working impeller is made of alloy steel in which the Cr content is high, within 24-28%. The short shaft is quite strong, it is installed on bearings and stuffing boxes. They work in an oil bath and provide a landing fit, even under severe operating conditions.

Slurry-type hydraulic pumps can be installed on an amphibian or conventional excavator boom when the equipment is connected to a hydraulic system. You can use this equipment on the power frame of the soil of the intake.

Solid inclusions in the pumped medium can be contained in a volume of up to 70%. The maximum fraction of solid elements can be 120 mm. The temperature of the pumped medium is equivalent to 60 ° C or less. The maximum specific gravity is 1.4 kg / dm 3 . The acidity level of the pumped mixture reaches 9.5 pH. The maximum immersion depth is 30 m, in the case of special versions, this parameter is increased to 120 m. In this case, the version with a pressure compensator is presented.

Conclusion

Slurry pumps can not be used in idle. If this recommendation is neglected, then you can face premature wear of the nodes. A number of manufacturers provide for the presence of a dry-running sensor, which blocks the operation of the unit, if necessary.
