L4 SCREW PUMPS

L4 Pumps are self-priming screw pumps with two screws in double volute and hydraulically balanced design. The drive torque is transmitted from the double helix drive screw to the likewise double helix idler screw via herringbone gears. The screws rotate closely meshing but without contact in the spindle bore of the interchangeable pump casing insert. As a result of the special profile geometry sealed cavities are formed which transport the pumped liquid continuously with low shear and without turbulences from both suction chambers axially to the discharge chamber. For optimum strength and low shaft deflection both drive screw and idler screw are manufactured from single piece bar stock.

LEISTRITZ _L4 screw pumps_1000x1000

L4 SCREW PUMPS

Leistritz screw pumps in the L4 range are twin-screw, double-volute, self-priming positive displacement pumps. They are used to pump aggressive / non-aggressive, abrasive / non-abrasive low to high-viscosity fluids with lubrication / non-lubrication properties.

Performance Data

  • Flow rate: Max. 5,000 m³/h (22,000 GPM)
  • Differential Pressure: Max. 150 bar (2,175 psi)
  • Viscosity: Max. 150,000 cSt
  • Pumping Temperature: Max. 350°C (662°F)

Advantages

The intelligent design of the Leistritz screw pumps offers enormous advantages over other pump technologies, like:

  • low-pulsation pumping of the fluid
  • extremely low vibration and noise
  • high flow rates
  • pumping a wide range of viscosities
  • low-wear operation
  • long service life
