L-BPEP

The L-BPEP is a two stages overhung pump using two  low flow design impellers in back to back configuration  enclosed in a radially split. 
Nozzle arrangement available in several configurations.
The L-BPEP meets API 610 11th ed. design criteria and maintains all the advantages given by the PEP solution  such as no backflow and high stability at low flow conditions, low NPSHr without the use of inducers,  use of API 682 standard mechanical seals, high reliability and maintainability.
In the L-BPEP all the radial and axial forces imposed by the impellers on the shaft (which are already small thanks to the enhanced hydraulic design)  are fully balanced through the back to back  and opposite discharge ports configuration.
The bearing frame and shaft size have been increased compared to the single stage PEP version to ensure minimum shaft deflection under all operating conditions.
The L-BPEP can be used to handle water, chemicals and hydrocarbons on a capacity range up to 19 m3/h against a total dynamic head up to 550 m.l.c. without the use of speed increasing devices. Standard design pressure of the casing is  7.0 MPa  (70 Kg/cm2), standard suction and discharge flange rating ANSI 600 RF. 
All API 610 material combinations, except I-1 and I-2 (cast iron), are available. 
L-BPEP can also be manufactured in special alloys to handle aggressive media.
