High Pressure Effects on Capacity This pump has been designed to provide a high degree of repeatability throughout a wide range of pressures. The capacity that can be expected is nearly that of theoretical displacement. As discharge pressure increases, a small decrease in capacity can be expected, approximately 1.0 to 3% per 100 psi.

2.1 Unpacking When unpacking, check all items against the packing list to prevent discarding parts with packing material. Whenever possible, unpack the equipment at the installation site. 2.2 Location Sufficient space should be provided around the pump to allow for routine maintenance.
Page 28
2.6 Piping GENERAL CAUTION: Piping material must be compatible with the fluid being pumped. Piping rating must be selected to withstand the maximum system pressure and temperature. a. See the Typical Installation drawings for general piping layouts and valve recommendations. b.
Page 29
DISCHARGE PIPING a. Discharge piping should be the same size or greater than the discharge fitting. b. The pipe pressure rating should be greater than the pressure relief valve setting (which is normally set 20% above system pressure). c. Discharge pressure of the pump must exceed the suction pressure by at least 10 psi.
3.1 Preparation for Operation 3.1.1 Gear Box GENERAL CAUTION: To prevent damage to the gear train, ll gear case before starting with the oil furnished. Remove the over ow plug from the gear case (high), and add oil until the oil level is level with the bottom of the over ow threads or slightly above (slight over ow).
h. After both the hydraulic system and the pumping head are primed, adjust the pressure relief valve (PRV) to the system pressure (by either pumping into system or by using a temporary portable manifold containing a pressure gauge and backpressure valve). Set the PRV per instructions in paragraph 3.1.4. i.
3.1.5 Calibration Since the stroke adjustment is marked in percent of full stroke, it is necessary to calibrate the pump under normal operating conditions to determine the actual delivery at a given setting on the stroke adjustment scale. To obtain signi cant data from which the calibration curve can be drawn, the pump operator must duplicate the exact conditions that the pump will encounter when in service.
3.2.4 Adjustment of Feed Rate Feed rate is governed by frequency of the pump stroke, the length of the pump stroke, and the strength of the solution to be fed. Frequency of Pump Stroke The frequency of stroke is a function of the gear set ratio (see table, below) and of motor speed (ac motor full speed only, optional dc motor with variable speed).
WARNING: WHEN DEALING WITH HAZARDOUS MATERIAL, IT IS THE RESPONSIBILITY OF THE EQUIPMENT USER TO OBTAIN AND FOLLOW ALL SAFETY PRECAUTIONS RECOMMENDED BYTHE MATERIAL MANUFACTURER/ SUPPLIER. 3.3 Theory of Operation 3.3.1 Drive Unit The motor drives the worm shaft, which in turn drives the worm gear/ sheave guide/eccentric shaft.
Page 42
Oil Refill Valve The loss of a small amount of oil occurs with each stroke through the piston/ cylinder interface gap and the air purge valve. If a provision is not made for refilling this oil, the diaphragm will eventually flatten against the rear baffle plate or the oil will vaporize.
Pressure Relief Valve This valve protects the diaphragm and the thrust-carrying parts of the drive from overpressure by relieving excess oil. This excess pressure may occur when the outlet becomes dead ended (by closing a discharge valve) causing the pump design pressure to be exceeded. This valve is flleld-set to relieve at 10 to 15% above the nominal process pressure.
3.3.5 Multiple Head Arrangement The Chemtube 2000 hydraulically actuated diaphragm pump is available as a simplex and as a double simplex pump, powered by a common drive unit. The liquid ends can have manifolded or separate suction and discharges, and may be any combination of two capacities, but will be driven at identical speed (SPM).

PARAGRAPH 4.5.2 FOR DETAILED GUIDANCE ON RELIEVING PRESSURE AND DRAINING. 4.1 General Routine maintenance of the Chemtube 2000 Metering Pump consists of TWO periodically performed operations: Periodic Cleaning to remove contaminants and deposits formed on parts in contact with the process fluids.
4.2.2 Clogging of Discharge Piping Where the solution joins water being treated, and that water contains considerable hardness, a deposit may form inside the discharge piping at the point of application. In time, this deposit can completely plug the line and must be removed.
4.4 Priming Troubles or Loss of Suction Difficulty in priming or loss of suction is usually encountered when there is a leak in the suction line. Refer to the troubleshooting guide for corrective action. If the pump is installed as shown on the Typical Installation drawing, the discharge drain valve may be opened to allow the pump to prime against atmospheric pressure.
4.5.1 Removing Pump From Service WARNING: USE EXTREME CARE TO AVOID CONTACT WITH THE MATERIAL AND POSSIBLE SEVERE PERSONAL INJURY. WHEN USING HAZARDOUS MATERIAL, OBSERVE ALL SAFETY PRECAUTIONS RECOMMENDED BYTHE MATERIAL MANUFACTURER/ SUPPLIER. USE APPROPRIATE PROTECTIVE CLOTHING AND EYE PROTECTION WHEN HANDLING HAZARDOUS MATERIAL. NOTE: Flush or wash removed parts in suitable diluting fluid.
4.5.3 Removing Valves NOTE: See Valve Assembly Drawings 430.500.000.010A-D for 2000 ltr/hr pump, Dwg. 430.500.000.020A-C for 1200 ltr/hr pump, and Dwg. 430.500.000.030A-C for 700 ltr./hr pump. WARNING: TO AVOID CONTACT WITH MATERIAL AND POSSIBLE SEVERE PERSONAL INJURY, NOTE THAT LIQUID IS PRESENT BETWEEN VALVE AND UNION.
g. Install the suction valve and tighten the clamp. h. Flip the flange to pour the intermediate fluid to the side of the tube until it overflows at the top fill hole. NOTE: Use straight propylene glycol if a leak detector is used. i.
f. Position a new flat diaphragm into the cylinder and carefully install the head (check the front limiter plate position), holding the head flat against the cylinder, then secure it with six bolts. g. Torque the bolts in a cross pattern to 15 ft-lbs initially, then tighten completely to 30 ft-lbs.
Page 54
e. Remove the spring, ball, and guide and inspect the seat for any defect. Clean all parts. f. Assemble in the reverse order and screw in the adjuster the same number of turns as recorded above. g. Use a new O-ring and install the pressure relief valve to the cylinder. h.
Page 55
Oil Refill Valve Assembly and Cylinder Installation a. Install the rear baffle plate to the cylinder. b. Insert the plunger and sensing disc assembly with spring to the cylinder. Locate the mark on the face of the sensing disc, where the longer slot on the plunger is oriented, and position it toward the top of the cylinder.
Page 56
d. Loosen the three set screws and back out flush with the surface of the knob. Do not remove. e. Place an oil pan below the knob and slide it off of the stroke adjust housing. The O-ring can now be removed for replacement. f.
Page 57
h. Install the arm to the pump and tighten the four bolts. i. Set the knob to “0%” pump stroke position and install the electric stroke positioner. Apply “Molykote” grease to the square drive shaft. j. Check for positioner calibration. Removal and Assembly of the Stroke Adjuster a.
4.5.8 Removing and Installing Motor (Driver Gearbox Only on Double Simplex) NOTE: Metric motor mounting arrangement, see Dwg. 430.500.000.060A&B a. Disconnect power to motor. If SCR speed controller is used, disconnect power to the SCR. b. If the motor has a tachometer, remove the wiring at the box terminal and record the polarity.
Page 59
NOTE : The cover is sealed to the gearbox with RTV. There are two screwdriver slots provided for the separation of the cover from the gearbox—a gentle tap with a mallet and screw driver will help to separate the two. e.
Page 60
n. Check for excessive radial clearance between the tailpiece and the journal bushing. If it is necessary to replace the bushing, remove the stroke adjust housing. Push out the old bushing and press in the new one. o. Clean all the parts and the gearbox and assemble in reverse order of disassembly.
Page 61
c. Remove the four bolts that mount the driven gearbox to the base. Record the location of the shims, if any, so that they can be installed at the same location. d. Remove the four bolts that secure the duplex bushing cap and housing. e.
(8) Watch for the O-rings and push the driven gearbox against the driver. The drive shaft tangs are properly engaged if the cap bushing made contact with the duplex coupling. Secure with four screws, but do not tighten. (9) Check that the gearbox is parallel with the base, install the shims to their respective locations, and tighten the four screws.
