Product DescriptionThree-screw pump for applications up to 1050 l/min and 100 bar
Positive constant displacement, rotary, three screw pump.
Flow rate per revolution 9.8 - 425 cm3 in 14 steps.The three screws, the central driven screw – the power rotor– which meshes with the two sealing screws – the idler rotors – the only rotating components of the pump, are hydrodynamically journalled in the pump housing. The axial pressure and friction loads on the pump rotors are hydraulically balanced. The power rotor is positioned axially by a ballbearing which operates at principally no axial load due to the hydraulic balancing of the rotor axial forces.
The following models comprise the E4 pump with a circular connecting frame – for mounting of the pump to an air/fluid
cooled flanged electric motor. The connecting frame comprises the pump shaft seal of the lip seal type.
• E4 xxBE with radial inlet for horizontal or vertical mounting.
• E4 xxTE with built-on inlet strainer for tank-top mounting for shallow tank operation.
• E4 xxJE as E4 xxTE with extended inlet pipe for deep tank operation.
