TG-300 Metering Pump

The TG-300 pump delivers 0 to 400mL/min (6.3gph) of controlled flow. It is a self-priming and quiet-running gear pump for use in a wide variety of metering or process applications with non-corrosive fluids such as oils and coolants. TG-300_On-Hand_NoBG_250 (6K) It can produce over 100 psi (6.9 bar) pressure. The original application was portable so the TG-300 is both lightweight and very compact.

Nominal operating voltage is 24VDC with a working range of 14 to 28 VDC. Nominal flow rate is 300 mL/min (4.7 gph) but it can be varied within the range of 0 to 400 mL/min (6.3gph). The pump can make over 100psi (6.9 bar) and should not be run over this level for any period of time. The TG-300 will lift and self-prime at least 2ft (.6m) when left wet. The stock pump ports are BSPT -19 (BS21 Rc) but other port styles are also possible. The rated ambient maximum temperature is 104f (40c) with pumped fluid as hot as 392f (200c). The pump will handle viscosity up to about 1,200 cSt.

The TG-300 can also be set up to respond to other process metrics. For example:

  • A filling application where flow needs to start off slow to minimize air entrainment and then ramp up to full flow before tapering back off to stop as the container approaches full.
  • A mixing line where the flow could be adjusted as the line speed increases and decreases.
  • A lab experiment where the flow needs to vary as a function of temperature.
  • A sampling pump where the TG-300 needs to run at a speed that correlated to the flow in a pipeline.
