Pump Model: SBH/50D (3/2D-HH) SBH/50D is equivalent to 3/2D-HH, a 2'' discharge high head slurry pump. SBH pumps are designed for heavy duty applications where require high head per stage at high pressure, which are suitable for long distance transportation or other applications where more than one pump in series are required. It's wet-end spare parts are made of high chrome alloy, a kind of highly abrasion and erosion resistant white iron, similar to ASTM A532. Material Construction:
