BL Series Dosing Pumps BL5-2
Blackstone pumps are more accurate than standard pumps due to the positive displacement design ensuring each stroke is identical to the strokes before and after it, thus keeping the flow rate consistent. A wide range of BlackStone pumps with different dosing capacities are available for your specific dosing needs.
- Manufactured with the highest level of mechanical precision from materials chosen for their inherent ability to resist the effects of aggressive chemicals.
- Designed to meet the ever changing needs of process industry.
- Each pump is supplied with discharge and suction valves.
BlackStone’s positive displacement solenoid driven pumps use a minimum number of moving parts, therefore reducing the chance of mechanical failure. Part wear and oiling associated with motor driven pumps (ball-bearings, gear drives and cams) are not a concern with these pumps.
Blackstone pumps are completely sealed during assembly and offer IP65 protection against splashes and spills providing excellent protection even in hostile environments. The fiber-reinforced polypropylene housing stands up to aggressive chemicals while offering superior strength under tough industrial conditions.
