AI Overview BETA

The Makro/5 is a hydraulic diaphragm metering pump that meters liquids at adjustable stroke lengths for a range of dosing duties. Its PTFE multi-layer diaphragm includes an electrical rupture warning system that signals a diaphragm fault through a contact. Boiler-feed-water treatment teams can use it for volume-proportional dosing of chemicals and additives in boiler feed-water treatment systems.

Power-end versions are available with ATEX certification for areas at risk of explosion
Designed to comply with API 675, among other standards
Single-pump capacity: 450–6,108 l/h at 25–6 bar
Correct installation under defined conditions: better than ±1% reproducibility over 10–100% stroke
Stroke length: 0–50 mm; adjustment range: 0–100%
