High-pressure pump from Watson-Marlow Bredel

Watson-Marlow Bredel has launched a 520RE high-pressure chemical injection peristaltic pump. The pump can achieve pressure capabilities of up to 100psi, and the combination of tube elements and pumphead design allows the 520RE to be utilised in situations requiring accurate metering, dosing and transferring of harsh chemicals, the company says.

The pump offers flows of 55 GPH at 30 psi to 7 GPH at 100 p and covers a wide range of applications including chemical metering, chemical injection and transfer of acids, bases and slurries found in water and waste treatment facilities. The 520 Series pumps and patented LoadSure elements guarantee correct loading every time, as well as easy one-minute maintenance with no snaking, twisting or pinching, Watson-Marlow claims.

Watson-Marlow Bredel peristaltic pumps are inherent metering pump with repeatability at 99.5%. Many models include integral digital drives and displays in washdown enclosures. These self-priming pumps accommodate flow rates from 0.1 microliter to 350 gpm and are extremely durable, withstanding pressures up to 232 psi. There are no internal universal joints, valves, dead corners or glands to impede flow and these pumps are reversible for back flushing lines. They can also run dry indefinitely without damage and provide up to a 30' suction lift.
