PUMPS

  • Peristaltic Pump Watson Marlow model 101U/R auto/manual control pump

    A low flow single channel pump fitted with a twin sprung roller design pumphead which accepts 1 6mm wall thickness silicone tubing from 0.5mm to 4.8mm bore The 101U/R has a speed ratio of 50:1 and can be programmed to respond to any common voltage or current input process signal. A front panel switch allows instant switching between auto and manual control. Speed is set digitally and the unit is reversible. A push button switch is provided for rapid priming. The pump will run in both directions; clockwise rotation gives longer tube life whereas conter-clockwise rotation gives greater pressure.

  • Peristaltic Pumps Watson Marlow 205series

    Comply with BS800, IEC335-1 & IEC34-5 (IP31)

    Variable speed pumps with a choice of 8, 12 or 16 channels and near pulse-less flow from an 8-roller pump head. The pumps have large bright digial display and membrane keypad, which is lockable for secure operation. Microprocessor control with DC servo motors provide instantly reversible flow, rapid priming and an ultra-low speed pulse mode to keep lines open; an auto-restart facility allows the pumps to recover automatically.

    Cassettes which accept the Watson Marlow range of colour coded manifold pump tubing (P78-500/568), may be added or removed from the pumphead without disturbina the Pumping action of any other channel.

    The model 205S/BA has manual speed control and the model 205 U/BA has a 25-pin socket for analogue control of speed or TTL control of direction and stop/start, with analogue and frequency tachometer outputs.

  • Peristaltic Pumps Watson Marlow 505DU/RL

    Digital and analogue manual control variable speed pump with a choice of maximum speeds of either 55 or 220 rpm and a maximum flow rate of 2.2 ltrs/min.

    The pump has a green backlit LCD readout and membrane keypad which is lockable for secure operation; microprocessor control with DC servo motors provide instantly reversible flow, rapid priming and an auto-restart facility allows the pumps to be controlled by a timer or to recover automatically from mains failure. The display may be chosen to show either rpm or flow rates by setting either the pumphead and tube size or by running a calibration dose.

    A 25-pin socket is provided for analogue control of speed or TTL control of direction and stop/start, with analogue and frequency tachometer outputs. Signal input is optically isolated and an RS232 interface is provided.

    The pump accepts tubing from 0.5 mm to 8.0 mm bore; clockwise pumphead rotation gives extended tube life and anticlockwise rotation gives greater pressure.

  • Peristaltic Pump Watson Marlow model 603S/R

    Providing higher flows - up to 11 litres per minute - but maintaining benchtop convenience the 603S/R accepts tubing between 4.8 and 15.9mm bore with up to 3.2mm wall thickness.

    The pump has LCD digital display of rpm from an optical tachometer and a ten-turn potentiometer which provides accurately reproducible speed setting over a 20:1 ratio. A safety guard on the pumphead cuts the power when opened. The case is finished in yellow stove enamel.
