Pump housings and gears are made of top quality bronze, shafts are
303 stainless steel. Bearings are designed of high performance
carbongraphite material selected for wear resistance and long
service life. Gear pumps are positive displacement pumps. Each
shaft revolution displaces a definite amount of liquid relatively
unaffected by the back pressure in the discharge line. Shaft speed
and flow are directly proportional. Recommended pressure limits are
100 PSI for water and non-lubricants, 150 PSI for oil and other
lubricants. The maximum shaft speed is 1750 RPM.
- Rugged corrosion resistant bronze construction
- Compact close-coupled design
- Stainless steel shafts
- Durable bronze spur gears
- Process lubricated carbon graphite bearings
- O-ring cover seal for maximum leak protection
- Buna Lip Seal -standard
- Easy field assembly to a variety of motor frames
- The relief valvee is only good for intermittent service. If used continuously, the pump will overheat. A built-in 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.
