Hanna BL series chemical dosage pumps are high specification products suitable for the accurate dosage of a wide variety of chemicals. They are of the positive displacement diaphragm type with magnetic solenoid motors, which are both inherently more reliable than the alternative mechanical motor drive pumps and are also simple to operate through an adjustable flow rate control. This control is mounted on the front face of the pumps and are also simple to operate through an adjustable flow rate control. This control is mounted on the front face of the pump and adjusts the stroke frequency, a pulsating LED light indicating stroke cycles for easy reference . The solenoid motor design also provides greater accuracy through consistent stroke lengths, thus keeping flow rate constant.
The pump is designed with durability and reliability as a priority and only the best materials are used. The diaphragm is one-piece ‘Teflon’ and the inlet and outlet valve assemblies use glass check valves and ‘Kynar’ springs for maximum corrosion resistance. The pump housing is made from fibre-reinforced propylene offering IP65 resistance against splashes and spills and the pump head is made from ‘Kynar’.
All pumps are supplied complete with necessary accessories for a complete installation including suction and discharge valves, 7m of polythene tubing and a ceramic weight.
