    Thus, the lowest mass-flow rate achievable with high performance balances is 0.03 to 0.04 grams per minute. To implement such low mass-flow rates, a ChemTec II equipped with an 8 RPM pump motor and a 1081 TANDEM pump head using #13 PharMed tubing is recommended.

  • Page 43: Linear, Volumetric Bioreactor Feed

    15.0 97.65 A ChemTec II CP-120 with a TANDEM 1081 peristaltic pump head (160 RPM pump motor) was used for this feed application. PharMed pump tubing #16 was chosen since it can generate flow rates from 4.6 ml/min. to 120 ml/min.

  • Page 44: Exponential Feed - Mass Flow, Example

    Interpolate from 1.75 gm/min to 2.39 gm/min over 12 hours, 30 minutes When executing the above program, the ChemTec II will generate an initial pump rate of 0.37 g/m, which is ramped up to 0.50 g/m during the first 12.5-hour segment. As shown in Figure 2, the six linear segments provide an excellent fit.

    With the TANDEM pump head completely opened, locate the mounting holes for the two 8-32 cap screws inside the lower pump channel. On the front panel of the ChemTec II, locate the mounting holes and the slotted pump head coupler.
  • Page 47 The pump tubing section located in the TANDEM pump head should be advanced at regular time intervals if the ChemTec II is heavily used. Only use high-quality Parker or Masterflex™ pump tubing. NOTE: When advancing pump tubing, the used pump tube section must be moved to the pump discharge side, i.e.

  • Page 48: Rh Series Pump Head Installation And Maintenance

    Remove the two screws (6-32 x ½ RH) from underneath the ChemTec II between and just behind the front feet. Remove the four screws (6-32 x 3/8” FH) from the face plate at the front of the ChemTec II. Carefully remove the pump/motor subassembly from the ChemTec II. Disconnect the motor cable from the pc board making note of how it was connected before completely removing it from the chassis.

  • Page 55: Magnetic Gear Pump Head Installation And Maintenance

    Magnetic Gear Pump Head Installation and Maintenance Magnetic Gear Pump Heads- General Information The ChemTec II MP-320 is equipped with a Magnetic Gear pump head and is recommended for metering applications requiring pulse-free flow. These are external gear type heads in which the spur gears rotate and intermesh inside the chamber, thereby creating a pressure differential between the inlet and outlet ports of the pump.
  • Page 56 Magnetic gear heads have self-priming capabilities when they are new. The ability to self-prime is dependent on the fluid being pumped, your operating system conditions, and the pump model being used, and how long the pump has been in service. If the pump self-priming capability of the magnetic gear pump heads in use has diminished or stopped due to wear, flooding the head will get the fluid moving again as this capability is greatly increased when the gears are wet.
