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. 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 ¼-19 (BS21 Rc) but other port styles are also possible. The rated ambient maximum temperature is 104°f (40°c) with pumped fluid as hot as 392°f (200°c). 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:
Because the electronics on the back of the pump are so versatile, these and endless other running modes are possible. Varna is always available to assist in getting our products set up. Give us a call for engineering assistance and support. 888-676-7774

Direct shaft couplings used in most Varna pumps eliminate the cost, bulk and limited life associated with traditional 'soft' couplings. While it takes careful design and precision manufacturing methods to get this to work, it produces a superior pump in all respects.
Customer Feedback "It was absolutely perfect - bolt in - set it and forget it!"
