Watson-Marlow Bredel Launches the Robust 521CC Industrial Pump for Chemical and Processing Applications

Watson-Marlow Bredel, the leading manufacturer of peristaltic pumps, offers the 521CC (close-coupled) pump for chemical and industrial processing applications. Ideal for abrasive and aggressive fluids, the 521CC pump is highly resistant to chemically harsh or corrosive environments. With an increased capacity of 1.3 GPM and a heavy-duty design, the 521CC pump offers high performance and low maintenance at a reduced cost.

The 521CC pump features a new pumphead, which is manufactured from durable PPS (polyphenylene sulfide), a high performance engineering plastic. This material is impact, chemical and flame resistant, providing the 521CC pump with physical properties that out-perform aluminum alloy. Increased track diameter and large occlusion rollers reduce stress and increase tube life by up to 20%. The easy-release rotor clutch and tube clamps enable fast tube changeover. Additionally, the pumphead accepts CHEM-SURE tubing, the most chemically resistant, long life peristaltic pump tube available on the market today.

The 521CC pump is versatile, featuring five close-coupled drive options. Among the drive options is the Varmeca integral inverter drive, providing 10:1 speed control, constant torque, built-in electronic protection, and ease of operation.

All of Watson-Marlow Bredel's 500 Series pumps provide a high, repeatable standard of volumetric accuracy (up to +/- .5%), wide flow rate capability, and easy maintenance. Designed to eliminate air locks, gas build-ups, and priming difficulties, the 500 Series pumps enclose the pumped media within the tube throughout the pumping process. This eliminates the risk of gland or seal leakage, chemical corrosion, and crystallization.
