| Product Name: | Bronze Rotary Gear Pump w/ motor & relief valve |
| Model Number: | N990RH-M46 |
| Manufacturer: | Oberdorfer Pump |
Oberdorfer Close coupled bronze rotary gear pumps.
- Bronze Construction with SS shaft
- Helical gears for quiet operation
- Self-lubricating carbon bearings
- O-ring seal for max. leak protection
- The pump drive shaft is connected to the motor shaft by a flexible coupling
- The relief valve is in the system if the discharge line contains any throttling devices, such as a shut-off valve, a spray nozzle or other restrictive device. This will return the liquid to the suction side or to the tank. If used continuously, the pump will over heat. The relief valve is strictly a safety device against overpressure. It will not work successfully as a pressure or flow control device. For this purpose a separate relief valve in the pressure line must be used.
