ROTH PUMP is the leading developer and manufacturer of LOW NPSH (0.3m NPSHr -FULL CURVE-) regenerative turbine pumps. For over 70 years Roth has been handling high head, up to 1645 m TDH, low flow, up to 34 m3/hr, boil point liquids.
High pressure usually means high speed, with the related NPSH problems, reduced mechanical seal life and high noise. Roth pumps provide low NPSH and required pressure quietly at 1440 or 2880 RPM. Up to 159 atm differential pressure.
+Liquids can be pumped at boiling point with only 0.3m NPSHr -FULL CURVE-
+Pumps are noncavitating
+Pumps are nonpulsating.
+Pumps are quieter than the motor.
+Seals and bearings can be changed in hours not days without total disassembly.
+Roth pumps need fewer stages than a comparable centrifugal pumps at the same speed.
Use of Roth LOW NPSH chemical plant/refinery pumps lowers distillation towers which lowers design, and construction costs.
