DC Bronze Rotary Gear Pump w/ relief valve

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.

• 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.
