„A-I” Series - Plunger dosing pumps comply with mechanical and performance API 675 standards. Furthermore they comply with ATEX standard, therefore they can be installed in Hazardous area.
Mechanism is an internal worm gear, fully oil bath lubricated with possibility to be coupled with others independently from the size and stroke number to obtain multi-heads unit.
Stroke adjustment can be carried with the pump at rest or in operation and it can be manual or automatic through automatic actuator driven by 4-20 mA; different BUS; pneumatic.
Accuracy within ± 1% within 10-100% of rated capacity.
As plunger pumps they are reliable and easy for maintenance and with the possibility to have flushing or leakage recovery system (optional).
