Nomad NTG-15 1/2″ Transflo™ AODD Pumps
NTG-15 TRANS-FLOTM 1/2″
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 6.5 gpm (24.7 lpm) against a discharge pressure head of 45 psig (3.1 bar) requires 60 psig (4.1 bar) and 7 scfm (11.9 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%.
