COLE-PARMER EW-74203-21 蠕动泵

Cole-Parmer Standard Peristaltic Metering Pump, Max flow of 2.1 GPH, 125 PSI, 220VAC

Pump at flow rates up to 158.5 GPH and pressures up to 125 psi — output volume is not affected by changes in back pressure Three versions now available to better fit your application requirements Low-range models have flow up 16 GPH (60.6 LPH) and pressures to 125 PSI (8.6 bar) Mid-range models have flow up to 33.3 GPH (126 LPH) and pressures to 125 PSI (8.6 bar) High-range models have flow up to 158 GPH (598 LPH) and pressures to 125 PSI (8.6 bar) Tube Failure Detection is included on all models — the system senses tube failure by detecting chemical in the pump head. No false triggering. NEMA 4X (IP66) Washdown Self priming even against maximum line pressure — suction lift up to 30 feet (9 meters) Choose a pump to achieve flow rates up to 158.5 GPH (600 LPH) and pressures up to 125 psi (8.6 bar) depending on your particular application. The pump performance allows for 30 feet (9 meters) of suction lift using water. Keeping chemical compatibility as simple as possible, the tubing is the only material in contact with the fluid. These pumps can achieve maximum pressure via a clockwise or counterclockwise rotation, giving great flexibility to your installation situation. Operator-friendly digital touch pad with menu-driven software make these pumps very easy to operate. The VGA graphic multicolor, backlit LCD displays remote/local control status, motor speed, output rate, input signal values, and service and alarm status. Multilingual display can present the information in English, Spanish, French, or German. A Tube Failure Detection (TFD) system senses tube failure by detecting the presence of the pumped chemical in the head. Built-in error correction prevents false triggering. Pumps come standard with Norprene® tube sets. Norprene tubing meets FDA criteria for food and offers excellent chemical resistance. Pumps with Norprene Chemical tubing (for superior chemical resistance) and Tygothane® tubing (for use with oils, greases, and fuels) are available online or by calling our Application Specialists for assistance. [A] Low-Flow Range Pumps Variable-speed DC can be adjusted from 1.0 to 100% of motor speed (100:1 turndown ratio) to meet your needs. The user-friendly interface includes a UV-resistant, backlit LCD and an eight-button, positive action tactile switch keypad. These pumps offer extensive input/output connectivity options. Inputs include: SCADA with 4-to-20 mA and pulse inputs for remote external speed control and either powered 6 to 24 VDC or non-powered dry contact closure for remote start/stop. The outputs include: one 250 VAC/3 A relay to monitor TFD (Tube Failure System) and FVS (Flow Verification System). If your application needs a 4-to-20 mA analog output signal scaled to the motor speed, please call our Application Specialists for details. NOTE: The pumps in this grouping (74204-16, 17, 18, 26, 27, 28) have 1/2" NPT(M) connections made from natural PVDF. [B] Mid-Flow Range Pumps These mid-range models maintain a volume output that is not affected by changes in back pressure. The system was designed to automate dosing down to the precision level of parts per million. The user-friendly interface includes a multi-color LCD with a ten-button positive action tactile switch keypad. Protect your pump using the programmable, 4-digit password built into the software. Pumps feature low-maintenance brushless DC motors that allow the pump speed to be adjusted from 0.05 to 125 rpm. Integrated sensor protects the operator and aides in tube replacement when the access door is open by limiting the pump speed to 6 rpm. A tube life timer is also integrated into the system to help determine when it’s time to replace your tubing. Operate the pump remotely or locally using the many input and output connections that are offered. Inputs include: one contact closure (remote start/stop), remote speed control via 4 to 20 mA, 0 to 10 VDC, high speed digital pulse, or contact closure pulse. The outputs include: three, dry contact or maximum 30 VDC / 115 VAC 1 amp contact closures, programmable 4-to-20 mA or high speed pulse, or proportional-to-pump output. Standard electrical features include three contact closures and one 6 amp relay. NOTE: The pumps in this grouping (74203-01, 02, 03, 04, 06, 21, 22, 23, 24, 26) have 3/8" compression connections made from natural PVDF. [C] High-Flow Range Pumps This system was designed to automate dosing to the precision level of parts per million. The user-friendly interface includes a multi-color LCD with a ten-button positive action tactile switch keypad. These pumps can be password protected through a programmable, 4-digit password built into the software. Low-maintenance brushless DC motor allows the pump speed to be adjusted from 0.05 to 125 rpm. There is also an integrated sensor that protects the operator and aides in tube replacement when the access door is open by limiting the pump speed to 6 rpm. A tube life timer is also integrated into the system to help determine when it’s time to replace your tubing. You can operate the pump remotely or locally using the many input and output connections that are offered. Inputs include: one contact closure (remote start/stop), remote speed control via 4-to-20 mA, 0 to 10 VDC, high speed digital pulse, or contact closure pulse. The outputs include: three, dry contact or maximum 30 VDC / 115 VAC 1 amp contact closures, programmable 4 to 20 mA or high speed pulse, or proportional-to-pump output. Standard electrical features include three contact closures and one 6 amp relay. NOTE: The pumps in this grouping (74203-41, 42, 43, 44, 46, 47, 48, 49, 61, 62, 63, 64, 66, 67, 68, 69) have 1/2" barb connections made from natural PVDF. What's Included: 6 ft (1.8 m) cord.
