1 1. Introduction The OMNI ® metering pump is positive displacem ent, mechanically operated reci procating diaphragm pump. Each pump consists of a power end an d a process end separated by a PTFE faced diaphragm .
2 2.1 Reagent H ead Assembl y The typical reagent head assem bly consists of reagent head, diaphragm , and suction and discharge cartridge check valves. This assem bly is the only part of the pump to contact the process liquid; consequently, maintenance is critical to pum p performance.
3 3. Equipment Inspection Check all equipment for com pleteness against the order and for any ev idence of shipping dam age. Shortages or damag e must be reported immediately to the carrier and y our authorized representative or distributor of OMNI ® pumps.
4 5.2 Piping S ystem 1. All systems should include a pressu re relief valve on the discharg e side, to protect piping and process equipment, including the pum p, from excess process pressures .
5 5.3 Suction Pr essur e Requir ements Although OMNI ® metering pumps have some suction lift capability, a flood ed suction (i.e., suction pressure higher than atm ospheric pressure) is preferable whenev er possible. The pum p should be located as close as possible to the suct ion side reservoir or fluid supply source.
6 Figure 4, stroke adjustment 6. Equipment Startup 6.1 Fastener In spection All pump fasteners should be check ed prior to pump operation, and occasiona lly during use. This would include reagent head m ounting bolts, motor mounting bolts, and the hardware that secures the pump to its foundation.
7 6.3 Priming the Reage nt Hea d 1. When handling process liquids, fo llow all applicable personal and fac ility safety guidelines. 2. Ensure that the pump is rea dy for operation and that all process conne ctions are secure. 3. Open the suction and discharge line shuto ff valves.
8 6.4 Calibration Figure 6, sample flow calibration curve All metering pumps must be ca librated to accurately specify stroke length settings for requir ed flow rates.

11 7.2.1 Diaphragm Removal & Reinstallation 1. Adjust the stroke setting to 50% and disconnec t the power source to the dr ive motor. 2. Relieve all pressure from the piping system. 3. Close the inlet and outlet shutoff valv es. 4. Place a pan underneath the pump head adaptor to catch any liquid leakage.
12 7.3 Check Val ves 7.3.1 General Description Most fluid metering proble ms are related to check v alves. Problems usually stem from solids accumulation between valve and sea t, corrosion of seating surfaces, e rosion, or physical dam age due to wear or the presence of foreign objects.

14 7.3.2 Check Valve Removal & Reinstallation , Cartridge type Valving that is of the cartridge design is intended to be replaced as an assemb ly. 15. Disconnect the power source to the drive m otor. 16. Relieve all pressure from th e piping system.
15 Inserting the check valve assmbly into the pump in the wrong dir ectiom, or having the check seat upside down, will prevent proper seals at the o-rings, decrease pump p erformance, and can cau se damage to the diaphragm.
16 7.4 Motor Rem o val & Reinstalla tion 1. Disconnect the power source to the drive m otor. 2. Disconnect the motor wiring from the motor. 3. Remove the four bolts retaining the m otor to the motor adaptor. The motor shaft fits into a b ore on the pump input shaft.
17 Figure 14, gearset components 7. Loosen the set screw (Item 9) on the worm gear (Item 8) and remov e it along with its shaft key (I tem 10). If you have the DC2 or 3 models go to step 8. I f you have the DC4, 5, or 6 m odels go to step 9. 8. Remove the Thrust Washers and Bearing (Item 11 & 12) from the housing.
18 7.6 Gearset Re plac ement 1. Apply PULSA lube grease # NP980006- 000 to both sides of the thrust washer and install onto the eccentric shaft. On the DC4, 5, and 6 models, the washer fits into a shallow counter- bore. 2. Assemble Worm Gear (Item 8) and key (Item 10) to the eccentric shaf t.
19 8. Replacement Parts 8.1 KOPkit Pr ogram OMNI ® KOPkits contain all replacement parts norm ally used in a preven tative maintenance program . ( PULSAlube grease is also available separately for prev entative maintenance program s. Refer to Section 6 – Equipment Sta rtup ).

23 11. Troubleshooting Difficulty Probable Cause Remedy Faulty power source. Check power source. Blown fuse, circuit breaker. Replace - eliminate overloa d. Broken wire. Locate and repair. Wired improperly. Check diagram. Pump does not start Process piping blockage.
24 Difficulty Probable Cause Remedy Discharge pressure too high. Reduce pressure. Water hammer. Install pulsation dampener. Stroke length at partial setti ng. Some operating noise is characterist ic of lost motion pumps. Noisy gearing, knocking Low grease level.
25 12. Piping Accessories Pressure Relief Valves Pressure relief valves are designed to protect chemical feed sy stems from damag e that may be caused by defective equipment or a block age in the discharge line. These valves function to lim it the pressure downstream of the pump.
