The Hanna Instruments diaphragm positive displacement pump uses a minimum number of moving parts, therefore reducing the chance of mechanical failure. Its maximum flow rate is 15.2L/h. The external flow control (the potentiometer) on the front of the pump allows for adjustment of flow from 0% to 100% of the nominal capacity of the pump. These pumps are manufactured to the highest degree of mechanical precision, with materials selected for their intrinsic abilities to withstand chemical attacks. The reinforced polypropylene housing withstands chemical attacks and offers superior strength, suited to challenging industrial environments. It is easy to install with wide, flat bases and mounting holes to allow tank, shelf or floor mounting (horizontal mounting).
