Leistritz screw pumps in the L2 range are twin-screw, single-volute, self-priming positive displacement pumps for the low-pressure range. They are used to pump slightly aggressive, slightly abrasive, low to high-viscosity fluids with good to poor lubrication properties.
L3 SCREW PUMPS
Leistritz screw pumps in the L3 range are three-spindle, single-volute, self-priming displacement pumps. They are used to transport non-abrasive lubricating fluids.
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.
