Available in discharge sizes from 3 to 14 inches, they can handle flows up to 8,000 gpm and up to 175 psi, and temperatures as high as 300 F. They have heavy-duty, high-tensile cast iron casings with Thru-Bore line boring technology for ease in maintenance, swapping of rotation, and conversion from packed to mechanically sealed. They have high-efficiency double-suction enclosed impellers made of bronze or other specified material, machined and polished and dynamically and hydraulically balanced.
