SECTION II INSTALLATION INSTRUCTIONS 1.0 GENERAL 1.0.1 UNPACKING & INSPECTION When unpacking a pump or chemical feed system, be certain that no parts are thrown away. Examine the equipment for possible damage. If damage has occurred, file claim with the common carrier within 24 hours. Neptune will assist in estimating the repair costs. 1.0.2 The Mechanical Diaphragm metering pumps should be located on a level surface. Three mounting holes are provided to anchor the pump securely to the mounting surface.
The hydraulic fluid supplied by Neptune is: EP Gear Oil, ISO #68, Norton Petroleum Corp., 290 Possum Park Road, Newark, DE 19711 (302) 731-8220 CAS No.64742-54-7, 64742-65-0 or 64741-88-4. Common sources for hydraulic fluid are: Alternate Oils Omala #68 Mobil Gear #626 Sun EP #68 Meropa #68 Manufacturer Shell Oil Mobil Oil Sun Oil Texaco All piping systems should include: 1.1.1 A separate system relief valve to protect piping and process equipment, including the pump, from excess process pressures.
2.0.3 It is recommended that all solution tanks be furnished with a low level cut off switch or low-level alarm and cut off switch to prevent the pump from running dry. Although the pump can run dry for a few minuets. OPERATION AGAINST A DRY SYSTEM FOR A PROLONGED PERIOD MAY CAUSE DAMAGE TO THE PUMP DIAPHRAGM AND REDUCE THE OPERATING LIFE OF THE PUMP. 3.0 DISCHARGE PIPING 3.0.
SECTION III NORMAL MAINTENANCE 6.0 MAINTENANCE Under normal conditions, the Mechanical Diaphragm metering pumps should not require any significant amount of maintenance. It is advised that periodic visual observations be made of the oil level to make sure that it is over the worm gear. The liquid end of the pump should also be inspected for leakage. These observations should be made regularly. The Gear oil should be drained and replaced when necessary, removing the drain plug at the side of the pump.
6.3.0 LIQUID HEAD REMOVAL, INSPECTION, AND REINSTALLATION CAUTION If the diaphragm has failed, any process fluid would pass through the bleed hole located behind the diaphragm. Handle any liquid with appropriate care. Mechanical diaphragms should operate for approximately 2000 hours under normal operating conditions; however, the accumulation of foreign material or debris and abnormal operating condition or simply age can cause failure. Failure can also occur as a result of system over pressure.
