Dosing pumps
• Designed for all environments•Reliable
•High quality material
•Ideal for aquaculture applications
Rugged Design Blackstone pumps are completely sealed during assembly and offer IP65protection 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. These simple and reliable chemical pumps are specially designed withPVDF and PTFE heads and diaphragms to resist damage from even the
most corrosive chemicals. Versatility Blackstone pumps have been designed to meet the ever changing needsof industry. To accommodate diverse applications, the pumps can be easi-
ly mounted anywhere in your plant with their broad, flat base and mountingholes for tank, shelf or floor mounting (horizontal). The rear of the pumphousing also provides mounting holes to facilitate vertical mounting: wall,
tank or machine. With the pump valve assembly and unit controls both located on the front of the pump, there is never a problem with installation or
flow adjustments. Simple Operation Blackstone pumps are equipped with a single control for pump output. Theexternal Flow Rate Control (potentiometer) on the face of the pump allows
you to adjust the percentage of flow from 0 to 100% of the pump's rated
capacity. This feature eliminates the need to worry about stroke lengths andpower settings. An LED indicator lights up each time a stroke begins. Thisallows the user to assess the stroke rate from a distance. High Quality Materials Blackstone pumps have been manufactured with the highest level ofmechanical precision, from materials chosen for their inherent ability to resist
the effects of aggressive chemicals. When you select a Blackstone pump,
you are eliminating the time consuming effort involved in picking the right
material for your application.
Blackstone pumps are supplied with the highest quality material as standardequipment, not optional. The diaphragm utilizes one-piece construction of
PTFE, which unlike conventional laminated diaphragms will stand up to the
test of time and wear. Ball valves are constructed in glass. The pumphead
and O-rings are all made of PVDF, PTFE and FPM/FKM which offer unsurpassed resistance.
