When process designs use API 610 centrifugal pumps for dual-service applications, use of the Split Flow feature provides unique benefits:
Permits use of two pumps instead of four – capital savings
Allows use of smaller motors – kW savings
Provides better pump-to-system hydraulic fit, as defined by API criteria
Results in longer mean-time-between-repairs (MTBR) for seals and bearings
The Split Flow principle (Fig. 1) is used with single-stage, overhung-type pumps (horizontal or vertical inline) up to 200 hp. "HP Innovations," January 1998, described two 60-hp, 3,600-rpm prototype units in commercial refinery fractionator reflux service since June 1996. Conventional
