About the Thermo 860-1050 Masterflex I/P Precision Brushless Drive Remote I/O, 33-650 RPM I/P Standard Process Pump Product Benefits Brushless motor handles challenging applications with minimal maintenance. Non-chip epoxy-coated, washdown IP55-rated steel enclosure protects against moisture, chemicals, and dust. Speed control via three-turn potentiometer for quick, easy adjustments. Speed is displayed on an easy-to-read LED display from 0 to 100% of full speed, with 1% resolution. Remote outputs: “pump ready” signal and 4 to 20 mA outputs (requires 77300-32 remote cable kit). 1.8 m (6 ft) line cord with IEC 320/CEE 22 socket. Industrial Process Pump: Reversible, maintenance-free brushless motor with precise PWM control via a digital signal processor (DSP). Digital display of flow rate, dispense volume/cumulative amount per dispense, copy, and motor rpm. Calibrate in system for accurate flow rate display. Keypad lock feature prevents accidents or tampering. Remote control of flow speed (4 to 20 mA), direction, on/off, and tachometer output. 1.8 m (6 ft) line cord with IEC 320/CEE 22 socket. 860-1050 SPECIFICATIONS : Output Speed 33 to 650 rpm Torque output, Maximum Continuous 540 oz-in (39 kg-cm) 380 oz-in (27 kg-cm) @ 40°C Ambient Start-up 960 oz-in (69 kg-cm) Speed regulation Line ±0.25% F.S.

(35 cm x 25 cm x 23 cm) Weight: 22 lb (10 kg) Enclosure Rating: IP55 per IEC 60529 Environment Temperature, Operating: 0 to 40°C (32 to 104°F) Temperature, Storage: –25 to 65°C (–13° to 149°F) Humidity (non-condensing): 10 to 100% Altitude: Less than 2000 m Pollution Degree: Pollution Degree 3 (Indoor use—sheltered locations) Chemical Resistance: Enclosure is painted steel Compliance: UL508C, CSA C22.2, No. 14 (For CE Mark): EN61010-1 (EU Low Voltage Directive) and EN61326 (EU EMC Directive) Description and Specs for the Thermo 960-0000 (AKA The Cole Parmer 77600-62 Pump Head) Highest flow rates, best pressure and suction performance of any I/P pump head Polyester and stainless steel (SS) construction withstands tough process environments Versatile mounting configurations—mount with tubing exiting to the top or side for flexible setup C-shaped design allows tubing to enter and exit the same side of the pump head—facilitates connection to tubing inlet and outlet Adjustable tubing retention; adjust to prevent tubing movement in head Ideal for industrial process and production applications requiring a single pump head, this heavy-duty three-roller pump head produces flow rates up to 19 LPM—the highest of any I/P pump head. Simple to load, it accepts Masterflex I/P high-performance precision pump tubing for greater pressure generation and suction lift, enhanced ability to pump viscous fluids, and longer tubing life. Adjustable tubing retention holds tubing securely in place and prevents movement while in the head. The I/P High-Performance pump heads are compatible with I/P drives that accept two or more pump heads. Drives that accept two heads have enough torque to run pump head even under difficult conditions such as high back pressure. Note: High-Performance pump head is not stackable.
