Gravel / Sand Pump

   Type EIS WG/WGH series gravel pumps are designed for continuously handling the most difficult higher abrasive slurries which contain too big solids to be pumped by a common pump. They are suitable for delivering slurries in mining, Explosive sludge in metal melting, Slag granulation, Dredging in dredger and course of rivers, Tunneling and other fields. operation.

   EIS Industrie gravel pumps are single-stage single suction cantilever horizontal centrifugal pump with advantages of light weight, good cavitation performance, good wear resistant, wide flow channel, convenient for installation. The discharge direction of the pump can be oriented in any direction of 360°.

Type EIS WG/WGH pumps are of high-head ones. This type of pump possesses the advantages of easy installation and operation, good performance of NPSH and abrasion-resistance. The construction of this pump is of single casing connected by means of clamp bands and wide wet-passage. The wet-parts are made of Ni- hard and high chromium abrasion-resistance alloys.

Gravel or Dredge pump?

The heavy-duty dredge pump design typically caters for low head high volume duties whereas the gravel pumps is best suited to the higher head cyclone feed and long distance pipeline duties.

Benefits of our gravel pumps:

• Our sand gravel and dredging pumps are designed to provide continuous pumping of highly abrasive slurries containing large particles at high maintained efficiencies with low maintenance and ownership costs.
• Our Heavy Duty Gravel Pump is designed for higher head duties such as cyclone feed, long distance pipelines and high static discharge heads.
• The range provides excellent wear life while maintaining efficiency during the wear cycle, providing a better total operating cost. A wide variety of shaft seals provide a perfect fit for a wide range of applications.
• Pass very large solids not capable of being pumped by other slurry pumps.
• Applications like dredging, gravel pumping, large particle solids transport.

APPLICATIONS

• Mill discharge
• Dredging
• Cyclone feed
• Sugar beet
• Sand reclamation
• Suction hopper dredging
• Slag granulation
• Barge loading

Design Features:

• The unique segmented clamp ring on larger size units and solid on smaller pumps, facilitates casing rotation to any angle, reducing the need for costly high wearing bends. Minimal maintenance is required.
• Impeller expulsion vanes reduce gland pressure and intrusion of high concentrations of solids in the gland area. Efficiency is maintained by minimizing suction side recirculation.
• Specially designed and shaped impeller vanes allow the handling of extraordinarily large particles. The unique casing design and sealing vanes prevent abrasive solids intrusion at the sealing faces.
• The large, robust casing has been designed to reduce internal velocities, resulting in minimum efficiency loss and improved casing wear life. The casing is made up of three components to reduce maintenance time and costs associated with a one-piece design.
• Heavy-duty grease lubricated taper roller bearing assemblies are fitted as standard. A rigid large diameter shaft with reduced overhang minimizes deflection and vibration under all conditions, ensuring trouble free operation. Unusually high service factors enable the assembly to carry all radial and axial thrusts.
• A unique “-10” (dash 10) end cover assembly comprising V-seals, double piston rings and an external finger with grease lubricated labyrinths are standard with all gravel pumps.
