Replaceable and high wear-resistant metal liners or rubber liners are adopted to make the pump work longer Slurry pumps of  ZJ Series 

In my company we divided them into several ranges, in this section we will show the ZJ series series Type ZJ/ZJM/ZJH/ZJHP/ZJL/ZJD pumps are designed with double volutes that pump body and cover has been fitted with metal or rubber liner( included impeller,liner insert, insert plate etc), but no rubber liner for type ZJ/ZJM/ZJH series pumps. A cast rion of S.G iron of pump body and cover depending on the working pressure, casing split on the vertical centreline serves to support and be connected by means of bolts.
