Page 4: Introduction
1. Introduction The GLM7 metering pump is positive displacement, mechanically operated reciprocating diaphragm pump. Each pump consists of a power end and a process ® end separated by a Teflon faced diaphragm. Individual pumps will vary in appearance due to various liquid ends and accessories; however, the basic principles of operation remain the same. -
Page 5: Reagent Head Assembly
Reagent Head Assembly The typical reagent head assembly consists of reagent head, diaphragm, and suction and discharge cartridge check valves. This assembly is the only part of the pump to contact the process liquid; consequently, maintenance is critical to pump performance. -
Page 6: Equipment Inspection
3. Equipment Inspection Check all equipment for completeness against the order and for any evidence of shipping damage. Shortages or damage must be reported immediately to the carrier and your authorized representative or distributor of GLM7 pumps. 4. Storage 4.1.1 Short Term Storage of your GLM7 pump for up to 12 months is considered short-term. -
Page 7: Piping System
Piping System 1. All systems should include a pressure relief valve on the discharge side, to protect piping and process equipment, including the pump, from excess process pressures. An external relief valve is required! There should be no devices capable of restricting flow (such as a valve) located between the pump and the relief device. -
Page 8: Discharge Pressure Requirements
Discharge Pressure Requirements All GLM7 metering pumps are designed for continuous service at the rated discharge pressure. If system suction pressure exceeds discharge pressure (a condition sometimes described as “pumping downhill”), flow would be generated (siphoning) in addition to that caused by the pump. This results in a reduction in accuracy and loss of control over the metering process. -
Page 9: Equipment Startup
6. Equipment Startup Fastener Inspection All pump fasteners should be checked prior to pump operation, and occasionally during use. This would include reagent head mounting bolts, motor mounting bolts, and the hardware that secures the pump to its foundation. Most hardware can be checked simply to ensure it is not loose. -
Page 10: Oil Fill And Maintenance
Oil Fill and Maintenance 6.3.1 Oil Capacities It is recommended that adequate supplies of PULSALube oil be on hand for periodic changes and emergency requirements. The approximate amounts of oil required to fill the GLM7 pump to specified levels are: Pump Capacity Gearbox, Model GLM7 PULSALube EP Gear Oil... -
Page 11: Priming The Reagent Head
6.3.3 Oil Changes The recommended oil change intervals are dependent upon the operating environment and level of pump usage, classified as follows: Normal service: Clean/dry atmosphere, an ambient operating temperature of 0 C to 40 F to 104 F) and up to 2,000 annual operating hours. Severe Service: Humid atmosphere, an ambient operating temperature below 0 C (32 F) or... - Page 12 6. Start the pump at the zero stroke length setting and slowly increase the setting to 100 to prime the pump. If this does not work, it will be necessary to fill the suction line. 7. Filling of the suction line will necessitate the use of a foot valve or similar device at the end of the suction line so that liquid can be maintained above the reservoir level.

Page 13: Calibration
Calibration Figure 7, sample flow calibration curve All metering pumps must be calibrated to accurately specify stroke length settings for required flow rates. A typical calibration chart is shown above. Although output is linear with respect to stroke length setting, an increase in discharge pressure decreases output uniformly, describing a series of parallel lines, one for each pressure (only two are shown). -

7. Maintenance EFORE PERFORMING ANY MAINTENANCE REQUIRING REAGENT HEAD OR VALVE WET END DISASSEMBLY BE SURE TO RELIEVE PRESSURE FROM THE PIPING SYSTEM AND WHERE HAZARDOUS PROCESS MATERIALS ARE INVOLVED RENDER THE PUMP SAFE TO PERSONNEL AND THE ENVIRONMENT BY CLEANING AND CHEMICALLY NEUTRALIZING AS APPROPRIATE EAR PROTECTIVE CLOTHING AND EQUIPMENT AS APPROPRIATE Accurate records from the early stages of pump operation will indicate the type and levels of required maintenance. - Page 15 Figure 8, wet end components GLM7 diaphragms do not have a specific cycle life; however, the accumulation of foreign material or debris sufficient to deform the diaphragm can eventually cause failure. Failure can also occur as a result of system over pressure or chemical attack. Periodic diaphragm inspection and replacement are recommended.

Page 16: Diaphragm Removal & Reinstallation
Diaphragm Removal & Reinstallation 1. Adjust the stroke setting to 0% and disconnect the power source to the drive motor. 2. Relieve all pressure from the piping system. Take all precautions described under the WARNINGS on page 14, Section 7 to prevent environmental damage and exposure of personnel to hazardous materials. - Page 17 6. Remove all but one top reagent head bolt. Product will leak out between the pump head adaptor and reagent head as the bolts are loosened. 7. Remove the final bolt and rinse or clean the reagent head with an appropriate material. 8.

12. Thread the diaphragm (clockwise) fully onto the shaft. When reinstalling a used diaphragm it is not necessary to maintain the previous orientation relative to the reagent head or pump head hole pattern. 13. Remove the screwdriver from the oil fill hole and replace the cap. 14. -
Page 19: Check Valves
Check Valves Most fluid metering problems are related to check valves. Problems usually stem from solids accumulation between valve and seat, corrosion of seating surfaces, erosion, or physical damage due to wear or the presence of foreign objects. The valve incorporates a ball, guide, and seat. Flow in the unchecked direction lifts the ball off the seat, allowing liquid to pass through the guide. -

11. Piping Accessories Pressure Relief Valves Pressure relief valves are designed to protect chemical feed systems from damage that may be caused by defective equipment or a blockage in the discharge line. These valves function to limit the pressure downstream of the pump. Field adjust the pressure relief valve to operate when the discharge pressure exceeds operating pressure by 10-15%. -
