Single stage radial impeller, horizontal, radial split volute, foot or centerline mounting. Axial suction, radial discharge, suction and discharge flange pressure levels are the same. The pump body and impeller have a replaceable seal ring that balances the axial force in the pump through the balance hole. The shaft seal and auxiliary system piping configuration adopts API682 standard mechanical seal and flushing scheme. Various cooling methods such as natural cooling, air cooling, and water cooling can be configured according to working conditions.
