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
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.
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.
Recommissioning within no time
The pre-assembled, certified easy-tochange cartridge reduces downtime significantly by at least 80%.
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.
Standardized installation space
For standard DIN mechanical seals subjected only to suction pressure.
Easily accessible connections
For the sealing oil system and the flush.
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.
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
4. Short delivery times
The unique modular design allows the pumps to be delivered from stock within a very short time.
FLEXCORE SC (steel casing)Coated in steel for
the highest standards
A single, multifunctional FLEXCORE steel casing replaces all standard casing
types. For a wide range of pressure levels, flow directions, and standards.
Easily adjustable to the most varied installation situations. Suction and pressure
housing turnable to 4 x 90° – also available with axial suction. As a result,
FLEXCORE is able to replace all conventional screw pumps - even in existing
systems. For maximum availability, intelligent same-parts and maintenance
1. Axial suction
The FLEXCORE SC also allows axial suction. For example, for vertical installation using a integrated tank plate.
2. Extremely adaptable
Available flange connections DIN, ASME, or SAE
FLEXCORE CC (cast casing)Cast casing for an extremely
wide range of applications.
A single, multifunctional FLEXCORE cast casing replaces all standard casing
types. For a wide range of pressure levels, flow directions,
and standards. Easily adjustable to the most varied installation situations.
Suction and pressure housing turnable to 4 x 90°, with SAE flange connections.
As a result, FLEXCORE is able to replace all conventional screw pumps in
any installation situation - even in existing systems. For maximum availability,
intelligent same-parts and maintenance concepts.
1. Easy to retrofit
In any installation situation, FLEXCORE is able to replace almost all screw pumps that are customary in the market, even in existing systems.
2. Maximum operational reliability
Reliable pump protection thanks to the integrated, adjustable safety valve - as standard.
