Without complex commissioning programs and additional check valves or hardware requirements, Watson-Marlow Bredel peristaltic pumps are the simplest of all chemical dosing pumps. By completely containing the pumped fluid within a chemical resistant tube, corrosion or abrasion of the pumps mechanical parts is elminated. Additionally, the pumps do not suffer "gas locking" which is often a problem associated with dosing sodium hypochlorite.
Watson-Marlow Bredel's IP66-rated 520 pumps range facilitates analogue or digital RS485 network options for serial communication, incorporates 24V industrial logic and volt free pump-status I/O, and can be password protected. Logical to programme and easy to manage, 520 pumps have dual analogue inputs to control and scale speed, providing a drop-in replacement for piston pumps with variable stroke control.
Increasing the pumps' overall performance and pressure capabilities, 520 LoadSure tube elements enable flow rates up to 3.5 litre/min and pressure performance up to 7 bar, offering new application opportunities and directly competing with traditional positive displacement pumps.
The 'Value for Life' cost provided upfront also means that customers will benefit from the knowledge that there are no installation ancillaries, hidden parts or maintenance overheads. Maintenance is confined to a routine tube change which can be performed by the user and in less than one minute.
Carrying a five year warranty, the 520 pumps range offers users in water and wastewater, print and food processing industries a simple, extremely accurate and cost-effective chemical dosing solution.
