RR and RRH pumps are P.D. Twin-Screw pumps, designed and manufactured according to API 676 standards. The two rotors are machined from a single-block piece, and the intermeshing screws provide a synchronous operation thus balancing the axial hydraulic thrusts.
Finder P.D. Twin-Screw pumps are suitable for pumping both low and high viscosity fluids and provide special constructive solutions to applications where a steady flow is required.
