LEISTRITZ FLEXCORE
DESCRIPTION
Flexible and powerful – this is our new screw pump innovation FLEXCORE. Not only can it be installed in various existing piping system, it also impresses with a broad application range. For the start of the new pump series we introduce the FLEXCORE 25 and FLEXCORE 32 with flow rates from 7 l/min to 50 l/min and from 15 l/min to 100 l/min.
FLEXCORE FACTS
>> Steel casing, hardened spindle set
>> FLEXCORE cartridge unit
>> Flange connections: DIN, ASME or SAE
>> One pump casing for two different cartridge units (FLEXCORE 25 & FLEXCORE 32)

L2 SCREW PUMPS
DESCRIPTION
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.
USER BENEFITS
>> High efficiency
>> Low operating costs
>> Only one shaft seal
>> Low-maintenance
>> Suitable for short dry runs
>> Maximum process reliability
>> Radial bearing brushes
>> Long service life

L4 SCREW PUMPS
DESCRIPTION
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.
USER BENEFITS
>> Spindles (shaft/rotors) manufactured in one piece
>> Low rotor deflection and non-contacting design
>> Arrow-toothed gears
>> Reduced noise level and low-maintenance
>> Replaceable insert
>> Low-maintenance
>> Special spindle geometry
>> Minimized pulsation and optimized NPSH value
>> Wide range of shaft seals
>> Customer-specific seals (single-acting, double-acting, API plans)

FLUID PUMP SYSTEMS
DESCRIPTION
Leistritz manufactures more than just individual pumps. In addition to the standard pump units in which screw pumps and the drive are mounted on a base plate, Leistritz also supplies complete pump systems for various fluid applications. They include, among other things, variable speed drives, sealing oil systems, external lubrication systems, instrumentation- and control systems.
EXAMPLE OF A PUMP SYSTEM
>> Mobile crude oil transfer pump
>> L4 range
>> 700 kW large diesel unit with exhaust gas line
>> Integrated control system
