4/3D Heavy Duty Slurry Pump frame type is D, it has higher head ,large flow rate than 4/3C Slurry Pump which have C type frame type,they are have 4INCH sution and 3 INCH discharge,they have the same fluids parts with high chrome or rubber materials.
3/2C metal liners slurry pump is smaller than 4/3D heavy duty slurry pump and 4/3C slurry pump,the suction diameter is 3INCH and the discharge diameter is 2 inch.
3/2C metal liners slurry pump,4/3D heavy duty slurry pump, and 4/3C slurry pump,they all belong to AH series Horizontal Slurry Pump. There are many other models AH type slurry pump, such as 1.5/1B, 8/6E,8/6F,etc.
The paramet sheet of ZJ series Horizontal Slurry Pumps are belowing:
The detail performance curves of 4/3D heavy duty slurry pump & 4/3C slurry pump with metal liners, they have higher flow rate and total head than 4/3C rubber liners slurry pump and 4/3D rubber liners slurry pump.
