20/18 Slurry Pumps for sale, Industrial pumps

Pump type HS is the standard heavy duty slurry pump which designed for the continuous pumping of highly abrasive,high density slurries with minimal maintenance requirements. The HS type China Slurry Pump is equivalnet to weir warman slurry pump AH. It maintains high efficiencies over the wear life of its components. This type of pump typically used in heavy minerals processing,mineral recovery process plant transfers,wet waste processes,recycling-washing plant, sand plant duties and chemical process plant.

Wet Parts in contacting with the medium are made of latest wear-resistance 27% chrome alloy white on with hardness 62HRC over, which has an highly abrasive for maximum resistance to strong abrasive, coarse particle.

They are widely used for mining, coal, metallurgical, power, building material and other industrial departments. This series of pump is suitable for various liquids performance, which is the first select product for handling mine mill slurry and tailing slurry. Basing on medium condition can choose different materials as A05, A07, A49 etc.

HS Slurry Pump Structure

Features:

● Elastomer or high chrome alloy liners provide corrosion &abrasion resistance, plus the interchangeability to reduce the maintenance cost and maximize wear life

● Large diameter, high efficiency impellers designed to offer maximum wear life and low operating cost, wide options of impeller for specific applications

● Gland dry seal, expeller wet seal or mechanical seals are available to suite different working conditions

● The bearing can be grease or oil lubricated which offer ease of maintenance and reduced downtime.

● The pump can be installed in multi-stage high pressure operation

● Large internal passage designed to reduce internal velocities to maximize wear life and lower operating cost.

Shaft Seal Structure:

Shaft Seal Types:

● Centrifugal Seal or Expeller Seal or Dynamic Seal-The centrifugal seal consists of expelling vanes on the back of the impeller and an expeller which rotates in unison with the impeller. The expeller is located in a separate chamber behind the impeller. The expeller acts as a turbine to reduce the pressure of the slurry attempting to escape around the back of the impeller. The expeller forms a pressure ring within the expeller chamber and prevents the slurry from passing into the shaft seal area.

● Gland Seal-The gland seal comprises a number of soft packing rings, compressed in a chamber (stuffing box)against a protective wear sleeve which fitted to the pump shaft. This type of seal requires continuous clean flushing water lubrication and cooling between the rotating shaft sleeve and the compressed packing, to prevent over heating due to the friction.

● Mechanical Seal-When it is essential for the leakage to be prevented entirely, then mechanical seals should provide a solution. The mechanical seal consists of a stationary and rotating face pressed together under mechanical and hydraulic pressure to prevent leakage.

Advantages:

★ The optimized structure is suitable for heavy duty application, ensuring longevity and longevity.

★ The double casing design of our heavy duty slurry pumps allows for axial splitting. Made of ductile iron, the pump casing is able to withstand the main pressure generated in the pump chamber. The lining is made of wear-resistant material and does not stick to the outer casing for easy maintenance and replacement.

★ The pump body of the coarse sand slurry pump is fixed to the pump base or the mount by a plurality of bolts. Under the housing or housing, the user can easily adjust the gap between the impeller and the suction pad. Packing gland seals, mechanical seals and centrifugal seals prevent mud leakage during pumping.

★ Hydraulic Modeling

★ The wet end parts are cast from hard metal, rubber or polyurethane. They maintain good hydraulic performance even when the pump is heavily worn. This helps the pump achieve optimum pumping efficiency levels for extended periods of time. Various impeller designs are available for coarse sand slurry pump for a variety of pumping applications.
