Material: Metal, ceramic,etc

1. Description:

Slurry Pump ZJ series are designed as single-stage, single-suction double-casing centrifugal horizontal slurry pumps. Various of pump speeds make ZJ series pump running under optimum operating conditions. Slurry Pump ZJ series can meet a wide variety of harsh conditions. Slurry pump ZJ 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.
