Bronze gear pump . 3/8" 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.
Gear pumps are positive displacement pumps. Each shaft revolution displaces a definite amount of l9iquid 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 lubricants. Maximum shaft speed is 1750 rpm.
A relief valve is 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. The relief valve is also available as part of the pump itself (R-model pumps). Often used for diesel fuel transfer, glycol, calcium and magnesium chloride de-icing fluid. 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.
