I plant ZYB-33.3A Regulator slag oil pump(1.5MPa) 
Slag oil pump can regulator trisomy main parts (pump, front cover, back cover) using steel, gears, shafts made of alloy structural steel, thrust plate, thrust plate with bronze composite materials with high wear resistance . A gear pump regulator residue can end clearance adjustable structure, 

when the can work for some time pressure drop occurs when the body can be covered by external fine adjustment of the pump gear pump end clearance to be adjusted, so that the pump the working pressure is restored and can be adjusted several times, so the effective life of the pump can be extended. Pump is mainly used to transport regulator slag and low diesel below 200 ℃, heavy diesel oil and other combustion containing impurities less oil spray occasions. Pump performance parameters and chart below.
