The HSC is our H2O Works™ heavy lifter. This pump is widely used to move clear water or low-viscosity, clear industrial process liquids at moderate heads. A fine combination of volume with ample head, this rugged, simple design offers extended service life, reduced maintenance costs and minimum power consumption. The split casing provides easy access to all rotating parts. This proven design concept meets Hydraulic Institute Standards in capacities from 50 gpm to more than 100,000 gpm, with single stage heads to 550 ft and two-stage heads to 1,150 ft. Available with up to 48-in. discharge outlets, these H2O Works pumps can be designed in vertical, horizontal and custom configurations to meet individual needs, including Zero Flush Technology. This is a sealing arrangement that requires no water. Wear rings protect the casing from wear. Ball or split sleeve bearings, located on both sides of the rotor, are enclosed in dust-proof cartridges. Twin stuffing boxes and double bearing construction ensure long packing life. Packed pumps are standard with split glands and a lantern ring. Replaceable packing box bushings protect the casing from packing wear. Optional mechanical seals are available. Bearing supports are integrally cast (12-in. discharge and below).
