4 (585) 426-4025SD 4 Operation & Maintenance Instructions polyblend LJPB series 600 & GeneralThis polyblend unit will perform the following func-tions: meter polymer dosage, regulate mixing water, provide uniform dilution and activation, operate on-line continuously, and feed solution to the point of use. Neat polymer from the metering pump and dilution water controlled by the solenoid valve enter the mixing chamber. Dilution and activation occur, yielding prepared solution ready for use. Neat poly-mer dosage rate is adjusted at pump face. Primary dilution (and post dilution) water are controlled by individual flow control Start-UpStep 1: Switch pump to external mode at pump 2: Prime polymer pump, using priming kit pro-vided with 3: Place unit power switch in Off 4: Energize power circuit that feeds unit. Sole-noid opens.
5 Allow mixing chamber to fill with water by opening primary dilution water control : Do not turn mixer motor on until cham-ber is filled with water, running dry will damage mechanical 5: Place unit power switch in On position. Mix-ing chamber motor 6: To turn pump On/Off and for polymer output adjustment. Output can also be adjusted at pump face by varying the stroke : For optimum pump performance, keep stroke frequency as high as possible. This is done by decreasing the stroke length setting. More stroke repetition with a shorter length is better than fewer strokes with a long stroke length. If stroke length is too short, pump prime may be 7: Adjust water flow at mixing chamber by turn-ing control valve. (The other control valve should be turned for post-dilution adjustment, if applicable.)NOTE: Do not run polymer pump unless water flow is established.
6 Polymer alone can plug discharge Water PressureThis unit is equipped with a flow regulator. The inlet water flow rate is maintained as pressure fluctuates. With the low dilution water rate of this unit, the regu-lator prevents pressure surges that could cause flow increases and affect solution concentrations. This device is factory set and not Solution OutputUnit output is determined by setting pump stroke length and stroke frequency together with setting dilution water flow. Establish desired solution volume and solution concentration, and then : 100 GPH (380 LPH) of .5% polymer solu-tion desired. A 2 GPH ( LPH) diaphragm pump is used. Determine neat polymer requirement.(100 GPH) x (.005) = GPH neat polymer (380 LPH)) x (.005) = LPH neat polymer Determine pump usage.( GPH) (2 GPH) = 25% pump capacity ( LPH) ( LPH) = 25% pump capacity Set ControlsA 2 GPH ( LPH) pump @ 100% stroke length and 25 strokes per minute will deliver GPH ( LPH).
7 However, 2 GPH ( LPH) pump @ 50% stroke length and 50 strokes per minute will also deliver GPH ( LPH) with a more homogeneous : Do not exceed polymer concentrations of 1% in the polyblend .

Equipment is Predicted Life SpanThere is no predicted life span of wear parts as each application and operation varies. Operating ProceduresFor normal operation, once settings are adjusted based on operation parameters, the system can sim-ply be turned ON or OFF. Special operating instruc-tions for Seasonal operation do not Emergency Operating InstructionsEmergency operating instructions do not apply to UGSI ChemFeed, Inc. Stranco Products equip-ment. In case of an emergency, TURN OFF POWER TO STOP Disassembly, Repair, & ReassemblyThis equipment is an open-frame design.

The low pressure port connects to the discharge side of the Function of differential pressure SwitchThe differential pressure switch ensures sufficient water flow is present before the polymer pump is energized.
10 This integral, automatic safety feature eliminates the problem of overfeeding neat polymer to an application without proper operation, the rate valve is adjusted to produce the desired flow through the system.
