(2.0) 2″ Band Clamp Pump
ARO band clamp pump models feature the Quick Knock Down (QKD) compression clamp system to facilitate easier cleaning, service and maintenance.
2” BD Series pumps are often used for transfer, filling and recirculation and batching in Chemical, Printing (ink), Marine and General Industrial applications.
Maximum flow: 185 GPM (700 LPM)
Overview
- New Quick Knockdown (QKD) facilitates rapid disassembly (and re-assembly) of components for inspection, cleaning and maintenance
- Anodized internal coating reduces corrosion and wear from abrasive fluids
- Expert (EXP) Series air motor
- Patented “Unstallable” unbalanced air valve design, which avoids stalling issues commonly associated with other pumps
- Exhaust valves that divert cold exhaust air from ice-prone components, which prevents freezing and downtime
- Ability to pass even large shear-sensitive solids without degradation or heat build-up
- BD Series pumps are often used for transfer, filling and recirculation and batching in Chemical, Printing (ink), Marine and General Industrial markets
