Product Overview
Synchronised chemical injection for process water systems requires a configuration that can handle digital control signals with precise adjustment. This pulse-capable Smart Digital S system is engineered for applications where maintaining a precise dosing volume relative to external flow signals is the primary service requirement.
The unit is driven by a 19 W motor drawing power from a standard 240v supply to maintain high hydraulic efficiency. It delivers a maximum dosing capacity of 15.0 L/h at a 4 bar maximum operating pressure, utilising a 1000:1 turn-down ratio to scale performance accurately down to a minimum flow of 0.015 L/h for sensitive chemical balance.
The hydraulic design utilises stepper motor technology to provide smooth and continuous dosing. This model supports manual speed adjustment via a scale knob alongside pulse and remote On/Off modes, supporting accurate dosing across the operating range.
Mechanical integrity is maintained by a PVC pump head and PTFE gaskets paired with ceramic ball valves. The unit features an IP65 enclosure and includes potential-free output relays for alarm or low-level status. It handles liquid temperatures up to 45°C and is supplied with an Australian power plug and 1.5 m cable.
FEATURES
- Integrated pulse input for automated chemical injection synchronised with external flow signals.
- Remote On/Off operation for integration with external control equipment.
- Low-level and tank empty signal inputs protect the pump from dry-run damage.
- 1000:1 turn-down range from 15.0 L/h down to 0.015 L/h for precise control.
- Stepper motor technology provides smooth and continuous dosing.
- Manual adjustment via 0.1-100% scale knob for simple on-site configuration.
- Two potential-free output relays for remote monitoring of alarms and chemical storage levels.
- IP65 rated enclosure with Australian power plug and 1.5 m cable.
