► Designed for high availability

The patented helical rotor design provides superior pumping speed , it is part of an advanced thermal management system , you can maximize pump performance and seal life bearings and motors to ensure that the pump has a long service life.

► widely used in various applications
GXS pump also offers a purge options , filters, header tank , inlet isolation valve and silencer , large flow of these parts and we specialize in providing the purge and solvent flush accessory together , can make the inside of the pump to keep clean , no need to disassemble for cleaning.

► long maintenance intervals , for the convenience
Long life is not oxidized gearbox oil maintenance intervals can be extended to five years. Quick connect device interface can accelerate the speed of the pump installation and replacement , thereby improving plant uptime .

► low running costs
The use of advanced sealing technology customization efficient motor and drive system greatly reduces power consumption. Minimal cooling water and purge gas demand and improved powertrain technology together to achieve a long maintenance intervals and requires little maintenance operation.

► impact on the workplace and the environment minimal
GXS pump incredibly compact . Even without the use of silencers, advanced helix rotor design can achieve extremely quiet , low- vibration operation .

► Simple installation and operation
GXS pump is easy to scroll through the wheels in place or using a forklift upgrade in place , with the joints and repair of equipment and processes provided by means of a connection , simply click the button to run .

► suitable for integration into larger systems
As standard , GXS pump and its combination with serial (RS232) communication and LAN -based network services . Optional modules to increase the parallelism ( digital I / O) and Profibus control functions.
