Masterflex Pump Drives for Hazardous Duty Looking for a peristaltic pump that handles hazardous duties? The Masterflex® I/P® Hazardous-Duty and Air-Powered Drives are specially-designed for hazardous or process applications. They can be used where special electrical precautions are necessary to ensure safe operation. The variable-speed drives provide a wide flow range for maximum flexibility. Consider the following scenario: Challenge: An agricultural company needed to pump ethanol at approximately 7 LPM to a stripping column. They needed a pump drive that would withstand the flammability of ethanol and tubing that provided excellent chemical compatibility. Solution: The Cole-Parmer Application Specialist recommended the Masterflex® I/P® hazardous duty pump drive and Viton® tubing. The I/P hazardous-duty drive is UL-listed for Class 1, Group D, Division 1 hazardous locations. The Easy-Load® pump head provides greater flow rate flexibility if the customer needs to use other sizes of tubing. With respect to the tubing, Viton has an excellent chemical compatibility rating with ethanol. The advantages of these Masterflex® I/P® drives are: Variable-Speed Hazardous-Duty Drives ■ Safer, fully mechanical speed control—adjust with lever, then lock setting ■ 115 VAC motor is UL-listed for Class 1, Group C and D, Division 1 hazardous locations ■ Achieve up to 11.2 LPM (3 GPM) using the High-Performance pump head, or stack up to two Standard or Easy-Load® heads (using silicone or C-FLEXR tubing) for up to 17 LPM (4.5 GPM); also compatible with L/S® pump heads. ■ Power switch and line cord not included—connect power using protected connections Variable-Speed Air-Powered Drives ■ Use when electrical power may be unsafe or impractical—for safe operation, carefully ground to protect from static electricity ■ Vary motor speed by using a regulator (included) to adjust air pressure—3⁄4-hp air motor starts smooth, generates less heat than an electric motor, and requires little maintenance ■ Achieve up to 19 LPM (5.0 GPM) using the High-Performance pump head, or stack up to two Standard or Easy-Load® heads (using silicone or C-FLEXR tubing) for up to 26 LPM (6.9 GPM) ■ Air-powered drive is ATEX Zone 2 approved; rated to EEX II 3 G c IIC T6; NEC Class 1, Division 2, Groups A, B, C, D, T6
