FLEXCOREPatented easy-to-change cartridge technology

The easy-to-change cartridge technology makes changing
the pump insert faster and easier than ever. In combination
with the proverbial Leistritz quality, which is virtually wear-free, FLEXCORE stands for maximum system availability.

Sophisticated down to the last detail

1

Huge increase in service life

thanks to the unique, patented Leistritz balancing system and a specially hardened spindle set, FLEXCORE pumps are virtually wear-free.

2

Three-spindle technology

The low-pulsation FLEXCORE screw pumps set the standard: Differential pressures of up to 40 bar, viscosities of up to 2,500 mm2/s, suction pressures of up to 8 bar in continuous operation.

3

Recommissioning within no time

The pre-assembled, certified easy-tochange cartridge reduces downtime significantly by at least 80%.

4

No special tools required

To change the pump insert, you only need to remove four screws. The easy-to-change cartridge technology allows the pump insert to be changed in less than 5 minutes, without special tools and without specialist knowledge.

5

Standardized installation space

For standard DIN mechanical seals subjected only to suction pressure.

6

Easily accessible connections

For the sealing oil system and the flush.

7

Highest operational reliability

Due to external bearings without harmful medium contact.

FLEXCOREThe first pump that is adaptable

The FLEXCORE pump family is the next evolutionary stage in the
pump sector. Thanks to the unique modularity of the housing and
the patented pump insert, it can adapt flexibly to any installation
position and standard. FLEXCORE provides a higher flow rate at a
smaller size. Extremely robust, virtually wear-free, and uniquely
easy to maintain.

ROTATION 180°

AXIAL SUCTION


Available with cast and steel casing – 24 month warranty

FLEXCORE is available with steel casing (SC) and cast casing (CC), each with 6 categories of low-pulsation flow rates from 7 to 564 liters per minute.

1. Maximum flexibility

Flexible to install due to the 4 x 90° turnable, split pump casing. Perfect for every application, with up to 20 different flow directions and 6 flow rate categories.

2. Technically superior

Superior performance data provide maximum operational reliability in an extremely wide range of applications. For example, during operation at a pressure of up to 40 bar or a
differential pressure of 10 bar, at a viscosity of only 1.1 mm2/s.

3. Digital early detection

With the “Smart Pump Sensor”, the pumps can be monitored and their data evaluated at any time. E.g. for maintenance based on operating hours, early fault detection, and fault
cause analysis.

4. Short delivery times

The unique modular design allows the pumps to be delivered from stock within a very short time.
