[1] Description:

Slurry Pump ZJ(L) series are designed as single-stage, single-suction double-casing centrifugal slurry pumps. The pumps are classified into vertical(ZJL) and horizontal(ZJ) version according to mode of construction. The ZJ(L) series pumps used international advanced solid-liquid two-phase flow theory and designed using the Minimum-Wear principle. Slurry Pump ZJ(L) series are suitable for handling abrasive and corrosive solids-bearing slurry with maximum density, which are widely used in power, metallurgical, mining, coal and building materials.

Typical Application:

  ·   Concentrate and tailing processing in concentration plant

  ·   Ash and slag removal in power plant

  ·    Coal slurry delivery and heavy media coal preparation

  ·    Transferring slurry in mining operations

  ·    Heavy media coal preparation

  ·    Main auxiliary products in thermal power unit

[2] Features:

  ·    High efficiency; energy-saving; light weight; reasonable construction; reliable performance; little vibration; low noise; easy maintenance.

  ·    Various design of the pump speed and versions enable the pump to work even under poor conditions.

  ·    The bearing layer and the wear layer can be separated. And the wet parts are made from strong abrasion resistance high-chrome alloy cast iron.

  ·    Three types of shaft seals, mechanical seal, packing seal and packing combined expeller seal can be adopted.

  ·    The pump discharge can be positioned to 8 directions at intervals of 45 degrees according to need. The inlet is horizontal.

  ·     The medium transferred temperature should not exceed 60ºC. The weight concentration of the mortar should not exceed 45%; mineral slurry, 60%.

  ·     The pumps can be installed in multi-stages for long distance delivery.

  ·     Drive mode: mainly direct connection(DC).

  ·     Lubricating way:40ZJ-200ZJ adopts grease or oil lubrication according to bearing box structure;250-500ZJ adopts grease lubrication.
