PFT has perfected the mixing helix. The new, innovative form is based on the model of nature, rather of the knee joint.
Benefit from this transfer of nature to technology:
Wear parts last longer: significantly reduced wear
Contact area increased by 9.7 times, therefore better protection of the motor shaft
Extended service life of heavily used parts
(Mixing spiral, driving claw)
Longer constant pump pressure
Significantly reduced maintenance
