  • Page 7: Section 1 Description

    SECTION 1 DESCRIPTION 1.1 GENERAL INFORMATION The Series G Model M is a reciprocating, chemical dosing pump capable of producing flows up to 500 liters per hour at pressures up to12 Bar. These pumps feature a mechanically actuated diaphragm Iiquid end, which eliminates the need for flow-restricting contour plates, and a stroke adjustment mechanism based on the variable eccentric principle instead of the traditional lost-motion design.

  • Page 8: Principles Of Operation

    Figure 1-2： 1.2 PRINCIPLES OF OPERATION DRIVE ASSEMBLY(SEE FIGURE 1-2) The pump consists of two major assemblies; the drive and the liquid end. Pump delivery is a function of the drive's stroke rate, liquid end size and stroke length. Stroke length can be increased while the pump is running by counterclockwise turning of the stroke adjustment knob.

  • Page 9: General Specfications

    As the diaphragm starts forward on the discharge stroke the pressure immediately rises inside the liquid end. When the liquid end pressure rises above the discharge line pressure; the discharge ball check is "pushed" upward and the process fluid in the liquid end flows into the discharge line. When the discharge stroke ends, the diaphragm momentarily stops again.

  • Page 10: Section 2 Installation

    SECTION 2 INSTALLATION 2.1 UNPACKING Pumps are shipped f.o.b. factory or representative warehouse and the title passes to the customer when the carrier signs for receipt of the pump. In the event that damages occur during shipment, it is the responsibility of the customer to notify the carrier immediately and to file a damage claim.

  • Page 12: Mounting

    2.4 MOUNTING Support the pump firmly in a level position on a solid, vibration-free foundation. The pump should preferably be positioned with the base above floor level to protect the pump from wash downs and to provide easier access for service. Be sure to allow enough space around the pump for easy access during maintenance operations and pump adjustments.

    Figure 2-2：...

  • Page 14: Npsh Considerations

    Figure 2-3: General Piping 2.6.1 NPSH CONSIDERATIONS Size piping to accommodate peak instantaneous flow. Because of the reciprocating motion of the pump diaphragm, peak instantaneous flow is approximately equal to 3.14 times the average flow. For example, a pump rated for 100 L/hr per hour requires piping sufficient for 3.14 x 100 L/hr (314 L/hr.). To minimize viscous flow losses when handling viscous liquids, it may be necessary to use suction piping up to four times larger than the size of the suction connection on the pump.

  • Page 15: Suction Piping Consideration

    2.6.3 SUCTION PIPING CONSIDERATIONS It is preferable to have the suction of the pump flooded by locating the liquid end below the lowest level of the liquid in the supply tank. To minimize the chances of a loss-of-prime condition, the pump should be installed as close as possible to the supply vessel.

  • Page 16: Valves

    2.7 VALVES Back Pressure Valves All metering pumps are prone to overpumping (excessive output) at low discharge pressures. To prevent this condition from occurring, it is necessary to maintain approximately 10 psi (0.7 bar) back pressure against the pump. This can be accomplished through the installation of a back pressure valve in the discharge line.

  • Page 19: Capacity Calibration

    Adjust the pump to the desired capacity. Lock the stroke adjustment knob (Item 320 in Figure 5-2). 3.4 CAPACITY CALIBRATION After the first 12 hours of operation, the pump may be tested and calibrated to find the exact pump capacity under specific operating conditions.

  • Page 20: Section 4 Maintenance

    Bellows Replacement. Check Valves As in the case of the diaphragm, Milton Roy Company recommends that check valve balls, seats, gaskets, and O-rings be replaced on an annual basis or every 5000 hours of operation. If highly corrosive material (acids, slurries, etc.) is being pumped, more frequent replacement may be required. Complete instructions for replacement of worn check valves are given in Section 4.5 Corrective Maintenance.

    Visual Check of Seal Integrity of Mechanical Assembly Check for leaks in the following components. If leaks exist, contact the factory for assistance. 1. Motor flange: If leaking, replace motor flange sealing gasket (Item 11 in Figure 5-2). 2. Stroke adjustment knob: If leaking, replace stroke adjustment seal (Item 160 in Figure 5-2). Checking the Pump Capacity Assuming the pump has been calibrated as described in Section 3, the capacity can be checked by shutting the valve from the supply vessel and opening the valve from the calibration column to the suction side of the...

REVERSE PUMPING ACTION (FROM DISCHARGE LINE INTO SUCTION LINE). Preliminary Operations 1. Set the pump capacity knob to 0%. If stroke locking screw (Item 320 in Figure 5-2) was previously tight- ened, slightly loosen the locking screw.
