1. Very high safety of operation. Mechanical actuate diaphragm.
Changeable eccentric drive
2. Power off seal,no leakage,with security delivery device,simple
3. It can transport high-viscosity mediums, corrosive liquid and
dangerous chemical goods.
4. The flow can be controlled via adjusting the length of stroke or
the motor frequency.
5. The diaghragm is made from multilayer complex structure to
promote the life span, the first layer is Teflon anti-acid
diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm
thick SUS304 that supporting the iron corn. The fourth is also the
EPDM stretch rubber to cover all of the body.
