Nomad NTG-25 1″ Transflo™ AODD Pumps

NTG-25 TRANS-FLOTM 1″

Metallic – Rubber – TPE-Fitted,

Air-Operated, Double Diaphragm pump:

  • Low cost.
  • High quality double diaphragm pump.
  • Simple to maintain, with a simple, time proven design.
  • Pump and parts interchangeable with Wilden®, but at a lower cost.

Because of the focus on high quality design they are simple to maintain, with readily available replacement parts and fast delivery.

  • Flow rates indicated on the following chart were determined by pumping water.
  • For optimum life and performance, pumps should be specified so that daily operation parameters will fall in the center of the pump performance curve.  Example: To pump 18 gpm (68.1 lpm) against a discharge pressure head of 45 psig (3.1 bar) requires 60 psig (4.1 bar) and 12 scfm (20.4 Nm3/h) air consumption. (See dot on chart).
  • Caution: Do not exceed 125 psig (8.6 bar) air supply pressure. Teflon Diaphragms: reduce flow by 25%.
