Spring return mechanical diaphragm dosing pump
„D” Series - Mechanical diaphragm metering pumps are normally used when:
- The dosed liquid contains small amounts of suspended solids
- A drip proof/air tight application is required
- The dosed liquid is a toxic solution
Each pump is fitted with a standard gearbox reduction system with a vertical mounted motor. The reduction gearbox is of a standard endless screw plus worm-wheel type, supported by bearing, fully lubricated in oil bath.
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. As mechanical diaphragm they are easy for maintenance.
Furthermore they comply with ATEX standard, therefore they can be installed in Hazardous area.
