Bronze Pedestal Gear pump with relief valve. Often used as a oil
pump on large ships to pre-lube the bearings.
- Gear pumps are positive displacement pumps. Each shaft revolution displaces a definite amount of liquid relatively unaffected by the backpressure in the discharge line. Shaft speed and flow are directly proportional.
- Maximum shaft speed is 1750 rpm.
- Recommended pressure limits are 100 psi for water and non-lubricants, 150 psi for oil and lubricants.
- A relief valve is a necessary 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. However, built-in relief valves are only good for intermittent service. If used continuously, the pump will over heat. 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.
- Service life will be increase substantially if the liquid pumped is clean and has a lubricity value. These pumps have extremely close tolerances.
- Pump housings and gears are made of top quality bronze
- Shafts are from stainless steel 303
- Bearings are designed of high performance carbon-graphite material selected for wear resistance and long service life
