Hanna BL series electronic dosing pump instruction manual
This document provides the instruction manual for the Hanna Instruments BlackStone electronic dosing pump series. It covers seven models ranging from BL1.5 to BL20, detailing their positive displacement solenoid pumping method which offers high accuracy and self-priming capabilities.
The guide includes preliminary examination steps, general safety precautions regarding chemical handling, and a functional description of the pump components such as the PVDF pumphead and PTFE diaphragm. It also provides flow rate charts correlating pressure with flow for each model.
| Max Flow Rate (BL20) | 18.3 Iph @ 0.5 bar |
|---|---|
| Max Flow Rate (BL1.5) | 1.5 Iph @ 13 bar |
| Pump Casing Material | fiber-reinforced polypropylene |
| Diaphragm Material | PTFE |
| Self Priming Max Height | 1.5 m (5') |
| Power Supply (-1 models) | 100/115 Vac; 50/60 Hz |
| Power Supply (-2 models) | 220/240 Vac; 50/60 Hz |
| Max Power Consumption | 200 W |
The pumps can handle a pumping pressure as high as 12 bar (176 psi).
Diaphragms, hose connectors, and pump heads use PVDF and PTFE.
The flow range is continuously adjustable from 0 to 100% of maximum capacity through a graded dial.
