They have been designed for the handling of highly abrasive or corrasive high density slurries, which are widely used in Metallurgical, Mining, Coal, Petroleum & Chemical,Transportation, River& Channel dredging, Building and Municipal projects.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. Pump body is bolted and spigotted to the frame and the discharge branch may occupy any one of eight positions. Side sealing vanes on both sides of shoulders may relive the leakage and raise the lifeand efficiency of pump.

Type ZJR/ZJM pumps  are double volutes too. Its casing and cover is fitting with the interchangeable rubber liner( included impeler, front and back liner).
Pump casing and cover can be exchanged with that of type ZJ/ZJM/ZJH pumps. Its driving and installation Diagram is correspondance to type ZJ/ZJM/ZJH series.
