Watson-Marlow Bredel Launches Industrial 520RE Loadsure Pumpheads For Increased Power And Performance

Watson-Marlow Bredel, the leading manufacturer of peristaltic pumps, has launched the 520 LoadSure® elements range. The combination of the tube element and pumphead design provides pressure performance up to 100 psi, allowing the 520 LoadSure elements pumps to be utilized in the chemical, water and wastewater, print and food processing industries.

Industrial process users can now have the functionality of the best-selling 520 metering pumps with expanded pressure capability. The new 520 LoadSure® pump offers flows of 55 GPH at 30 psi to7 GPH at 100 psi. Reliable, rugged and easy to use, the perfect metering pump covers a wide range of applications including high-pressure chemical injection of sodium hypochlorite, ferric chloride and other aggressive chemicals, low-shear metering of printing inks, dyes and brighteners, as well as simple transfer of viscous fluids such as adhesives.

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. Operator safety is ensured at all times by utilizing a new-look shade guard, sealed to withhold any spillages at atmospheric pressure. Drain port plugs allow for easy removal of spilt fluid and an optional float switch leak detector will stop the pump automatically in such conditions.

The 520 LoadSure elements series of cased and close-coupled pumps provide the ruggedness and reliability needed by industrial process users. The NEMA 4X 520UN/RE facilitates analog operation, incorporates 24V industrial logic and volt free pump-status I/O and can be password protected. For full industrial connectivity, the 520DuN/RE possesses both comprehensive flow calibration and RS485-network options for serial communications control by PLC.

"The increased performance provided by the 520RE LoadSure elements means that we are able to widen our customer base for 520 pumps considerably and compete directly against our competitors in markets that we haven't previously operated in," states Chuck Treutel, marketing manager for Watson-Marlow Bredel.

"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 associated with other pump types such as mechanical diaphragm pumps."

Watson-Marlow Bredel pumps contain fluids within the tube at all times, never allowing the fluids to come into contact with the pump mechanism. Entrained gas is pumped with ease, plus corrosion and damage is restricted to the consumable tubing element. This helps provide predictable life costs for the pump, as the tube is the only part that will need replacing.

Every Watson-Marlow Bredel peristaltic pump is an 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.
