CANADA’S LEADER IN ENERGY PRODUCTS EQUIPMENT PUMPS, COMPRESSORS & MOTORS BLACKMER PUMPS LG1 Series 1-Inch Pumps These motor speed pumps (1750 rpm) are excellent for small fill stations, vaporizer & low capacity transfer applications. Capable of providing between 4 to 13 US Gallons per minute with a built in bypass / relief valve that is connected back to the storage tank, they provide an economical pumping solution in a compact configuration. These curves are based on approximate delivery rates when handling propane or Anhydrous Ammonia(NH3) at 80°F (26.7°C). Line restrictions such as excess flow valves, elbows, etc., will adversely affect deliveries. For propane at 32°F (0°C), actual delivery will be further reduced to about 80% of nominal. Delivery of butane at 80°F (26.7°C) will be 60% to 70% of these values and may run as slow as 35% to 45% at 32°F (0°C). This loss of delivery is not a pump characteristic but is caused by natural thermodynamic phenomena of liquefied gases.
