CONGRATULATIONS! The FMI ΓQ PUMP LINE is one of the finest metering pump lines in the world. It features the unique valveless, variable,rotating and reciprocating pumping design of all FMI pump products and more. More consistent accuracy, more volume per stroke, moremotor drive options and more diverse flow control options including a dial indicator, 4-20 milliamp stroke rate controller and dispenser. 1. CLEAN FLUIDS. > Turn off the electrical power before checking pump for anyproblems. Connect motor, speed controllers, or any other electrical devicesbased on Fluid Metering Inc. specifications. Any unauthorized work performed on the product by the purchaser or by third parties can impair product functionality and thereby relieves Fluid Metering, Inc. of all warranty claims or liability for any misuse that will cause damage to product and /or injury to the individual. Power cables and leads should not be bent, pulled or inserted byexcessive force. Otherwise there is a threat of electrical shock or fire. Replace any in-line fuses only with fuse rating as specified byFluid Metering, Inc. When pump/drive is under operation, never point dischargetubing into face or touch any rotating components of pump. In a power down thermal overload cut-in condition, unplug orturn off power to pump. Always allow a cool down period before restarting: otherwise, injury or damage may occur. For 30 seconds after power is removed from pump/drive: do nottouch any output terminals. Electrical shock may occur becauseof residual voltage. > 7. 4-20 mA CONTROL for automatic response toremotely generated 4-20 milliamp signals is stan- dard on V200 controllers. The input can be eithergrounded or ungrounded. The current source con-nects to terminal posts mounted on front cover assembly of the STROKE RATE CONTROLLER. Besure to observe correct polarity. For complete hook-up and operating information see page 10. Do not put wet fingers into power outlet of unit. Do not operate with wet hands Do not operate drive assemblies that require a hard mount (to bebolted down) unless they are mounted per Fluid Metering, Inc. specifications, if not injury may occur and/or damage to unit. Do not touch any rotating pump or motor components: injury mayoccur. Do not run pump dry, unless designed for that service. Running dry is harmful to the pump, and will cause excessive heating due to internal friction. Check pump rotation and inlet/outlet pump port orientation beforeconnecting power to pump. If not injury may occur. When pulling out cords from outlets do not pull cord, grasp plug toprevent plug damage or electrical shock. Fluid Metering, Inc. Drive Motors become 8. PRESSURE Check your fluid circuit before applying powerto the pump!9. ELECTRICAL PROTECTION. . Do not operate pump against headpressures in excess of design specification. Drive arm on piston may bend or break under overload and other irreparable damage may be suffered. HOT and can cause aburn. DO NOT TOUCH! All FMI PUMPSare positive displacement instruments and should be protected by lowest possible ԓslo blow fuse or circuit breaker electrical arrangements. ԓQV unitscome equipped with .75 amp fuses. 10. NOISE AT HIGH PUMP RATES. 5. PISTON SEALS. The R408 seals that keep yourPUMP piston dry are not ԓjust ordinary plasticdiscs. They are precisely cut and hot formed fromsheets of a chemically inert fluorocarbon, specifi- cally formulated for resistance to wear, abrasion, heat and chemical attack.Each R408 seal possesses an exceptional me-chanical memory which allows it to maintain arelatively constant wiping pressure on the piston,compensating for seal wear as it occurs. Properly maintained in clean condition, the original seals on a FMI PUMP may be expected to last the life of the pump. If they are removed for any reason, they should be carefully cleansed of all foreign particlesprior to re-assembly. Seal seats must also be free ofparticles. (please see para 18) 2. COMPATIBLE FLUIDS > Abrasives in the pumped fluidmay damage cylinder and piston surfaces and should, therefore, be avoided. Carbon cylinder liners and stainless steel pistons are particularly susceptible to abrasion by particulate matter in the pumped stream. Ceramic piston/cylinder compo-nents are more tolerant of suspended solids ex-cept solids that tend to flock and impede the movement of the piston in the cylinder. . Pump only fluids com-patible with materials of construction of the pump head you have selected. idle. Slightly loosen the two thumb screws and turn the STROKE LENGTH ADJUSTMENT KNOB. Re- tighten thumb screws once the desired setting is reached. 3. WET OPERATION 4. FLOW VOLUME AND DIRECTION . The pumped fluid providessurface cooling and lubrication to the piston and cylinder of your FMI PUMP. Therefore, avoid dry operation (except pumps specifically designated ԓgas pump). . Angulardeflection of the cylinder with respect to the zeropoint on the calibration scale of your FMI ԓQ PUMP controls flow magnitude and direction e.g., with the cylinder pointer at 10 on the left scale, fluid will be passed from the right port to the left port at 100% of the maximum rated volume; with thepointer at 10 on the right scale, fluid will pass fromthe left port to the right port at maximum rate. Set at 5 on the scale, flow rate will be 50% of maximum; at 4, it will be 40%; at 3, 30%, etc., etc. The flow control setting may be changed (including flow reversal) at any time while the pump is operating or 6. DIAL INDICATOR. (optional) The Dial IndicatorKit is for fine adjustment and continuous monitoring of your ԓQ pump flow rate settings.To adjust Dial Indicator equipped pumps:1.Loosen thumb screws, turn STROKE LENGTHADJUSTMENT KNOB, moving cylinder assembly to neutral (zero-flow position).2. Adjust indicator pointers until they read zero onboth dials. 3.You are now ready for fine setting by turningSTROKE LENGTH ADJUSTMENT KNOB until you achieve desired flow rate on dial. To prevent system backlash always turn STROKE LENGTH ADJUST- MENT KNOB two turns or one full revolution of large dial beyond desired setting, then adjust back.
