主要特点:

1.Housings are completely sealed—IP66 and NEMA 4X rated

2.Washdown drive is easy-to-clean and resistant to commonly used cleaning and sanitizing solutions—simply hose down to clean

3.Brushless, maintenance-free motor offers ±0.1% speed control accuracy with a 6000 to 1 turndown ratio

4.Full remote control capabilities allow easy integration into automated processes

5.Flow rate: 0.006 to 3400 mL/min (up to 54 GPH) with L/S tubing. Flow rate depends on drive rpm and tubing size

6.Graphical LCD shows four operating modes continuous run, timed dispense, copy dispense, volume dispense. View pump performance continually

7.Menu-driven interface lets you select one of seven languages for programming and operation

8.Dispense by: Volume—in milliliters (0.001 to 99999 mL), liters, and gallons; Copy—1 to 9,999 dispense cycles; or SEC—time interval between each dispense cycle (1 sec to 99 hr, 59 min, 59 sec)

Remote control via sealed circular connector on drive:

--Speed control input scalable 0 to 20 mA, 4 to 20 mA, or 0 to 10 V;

--Pumping direction requires open collector or contact closure;

--Start/stop/purge requires open collector or contact closure;

--Tachometer output scalable 0 to 20 mA, 4 to 20 mA, or 0 to 10 V, open collector

9.Model 77975-25 features a 316 stainless steel housing. Use this drive in process, manufacturing, pharmaceutical, dairy, biotech, and food and beverage applications.
