The Oberdorfer N994 is a bronze close-coupled rotary gear pump designed for reliable and quiet operation in fluid transfer applications. Featuring 1/2" NPT ports and a Buna (NBR) lip seal, this positive displacement pump is ideal for clean, non-abrasive liquids such as water, oils, and mild chemicals within a pH range of 4 to 11.
The pump includes stainless steel shafts, precision-machined bronze helical gears for reduced noise, and self-lubricating carbon bearings for extended service life. It is directly mounted to a motor via a flexible coupling and adapter bracket, making it compact and easy to install.
