SECTION I GENERAL DESCRIPTION The Neptune Series 7000 Mechanical Diaphragm metering pump is a reliable metering pump of the Low-pressure diaphragm type. Under constant conditions of temperature, pressure, and capacity adjustment settings, a +/- 2% metered discharge volume is maintained. Rugged contoured composite diaphragm designed for high metering accuracy over a full 10:1 turndown range.
SECTION I NEPTUNE CHEMICAL PUMP COMPANY LIMITED WARRANTY All Neptune Pumps are tested at the factory prior to shipment. Each part used in their construction has been carefully checked for workmanship.
SECTION I PARTS ORDERING INSTRUCTIONS The complete model number and serial number of the pump must be furnished to insure prompt and accurate parts service. These numbers are found on the name plate (sample below) located on the side of the pump. Please refer to page number (13) for parts list. Ballooned drawing of the pumps can be found on pages (12) and (14). www.neptune1.com A DOVER CHEMICAL PUMP CO.
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 Industrial Tufoil Common sources for hydraulic fluid are: Fluoramics Inc Industrial Tufoil 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. *An external relief valve is required!! 1.1.2 Shutoff valves and unions (or flanges) on suction and discharge piping. This permits check valve inspection without draining long runs of piping.
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.

SECTION IV MOTOR OPERATING CONDITIONS 7.0 The normal temperature rise for standard motors is 40°C above ambient temperature and, thus, it might appear that the motor is operating at a higher than normal temperature. This situation is normal. As a precaution against motor overheating, it is recommended that the pump be located where adequate ventilation is available, It is also recommended that a MOTOR STARTER WITH THE PROPER OVERLOAD PROTECTION BE SUPPLIED AS AN ADDITIONAL SAFETY DEVICE.
