Page 3: Description
It is important that the pressure in the liquid end remain above the vapor pressure of the process fluid during the suction stroke. If the fluid pressure drops below the vapor pressure, cavitation will occur, negatively impacting the performance of the pump. If you suspect the possibility of cavitation, contact an LMI Master Distributor for assistance. -
Page 4: Product Code
Product Code Series G Pumps are available in a variety of different configurations. For a breakdown of the options included in a specific pump, compare the pump model number and product code found on the pump nameplate with the model/product code breakdown shown in Figure 1. -
Page 5: Installation
Installation Unpacking Pumps are shipped f.o.b. factory or distributor 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 6: Mounting
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. If in doubt, contact your nearest LMI Master Distibutor to determine the necessary pipe size. - Page 7 Vent Pulsation Dampener Safety Pressure Valve Gauge Back Pressure Valve Calibration Column To Injection Supply Tank Point Prime/Air Purge Valve Strainer Pulsation Dampener Metering Pump = Shut off Valve To Drain Figure 5: Typical Recommended Pump Installation Scheme Suction Piping Considerations •...
- Page 8 To prevent a blocked discharge line from causing damage to the pump, piping, or process equipment, install an LMI Safety Valve in the pump discharge line. This valve is designed and sized to handle system flow rates and pressures safely while resisting corrosion by the process liquid.

Page 9: Leak Detection
Leak Detection Series G, Model B pumps are equipped with a leak detection port. For ease of installation, each pump has a plastic tubing connector installed in the leak detection port (see item 448 in Figure 8). In the event of a failure of the oil seal (70 in Figure 7) or diaphragm assembly (261 in Figure 8), pump drive oil or process fluid will escape from this leakage port. -
Page 10: Maintenance
The pump can be calibrated by measuring the decrease in liquid level pumped from a calibrated vessel. This method is recommended for hazardous liquids because it eliminates operator contact with the liquid. LMI test-tube Calibration Columns are available for convenient and accurate calibration of any pump. -
Page 11: Shipping Pumps For Repair
Refer to the instructions in the “Corrective Maintenance” section. Check Valves LMI recommends that check valve balls, seats, gaskets, and O-Rings be replaced on an annual basis. If highly corrosive material (acids, slurries, etc.) is being pumped, some applications may require more frequent replacement. -
Page 12: Corrective Maintenance
Corrective Maintenance Before carrying out any servicing operation on the metering unit or pipes, disconnect electrical power from the pump, and take the necessary steps to ensure that the harmful liquid they contain cannot escape or come CAUTION into contact with personnel. Suitable protective equipment must be provided. Check that there is no pressure before proceeding with dismantling. - Page 13 Plastic Check Valves: Reassembly 1. Fit new O-Rings into position on the ball guide and seat. To assure a tight, leak free seal, new O-Rings should be used each time the check valves are disassembled. 2. Drop the ball into the curved inner chamber end of the ball guide. 3.
- Page 14 4. Position the check valve assembly onto the liquid end, trapping a gasket between the two metal surfaces. (Seat and pump head). 5. Slide the valve clamp (437) over the connection (435) and screw into the liquid end using the three screws (441,442) and their split washers (439).
- Page 15 Reassembly (Refer to Figures 7 and 8) 1. With the stroke adjusting knob at 100% and the diaphragm fully forward as in steps 1 and 5 above, screw the diaphragm assembly into the connecting rod until it reaches its natural mechanical stop. 2.

Troubleshooting Guide Symptoms & Remedies Pump will not operate ......• Low process liquid level in the tank. Add liquid. • Worn or dirty check valves. Clean or replace. • Blocked discharge line. Clear line. • Frozen liquid. Thaw liquid throughout pumping system. •... - Page 17 Motor and pump body hot ..... • Normal operating temperature of both motor and pump body is frequently uncomfortable to the touch. However, neither should exceed 200° F (93° C). • Power supply does not match electrical requirement of motor. Insure proper matching of power supply and motor.
