  • Page 9: Installation

    Installation Mount the single head pump vertically and use the spill recovery to drain chemical back to the tank in the event of tube failure. Vertical installation will help prevent chemical from collecting in the tube housing and on the floor.

  • Page 10: Suction And Discharge Lines

    Suction and Discharge Lines Allow slack in both the suction & discharge lines to prevent stress on the tube and fittings. The slack allows the tube fittings to flex to help reduce the chance of breakage and leaks. The suction line should not be flush with the nose of the strainer.

  • Page 11: Connections

    Connections The connections to the pump tube fittings and to the injector are a compression type seal. Overtightening the connections breaks the seal and can cause a twisted tube, damaged fittings, or crushed ferrules. A twisted tube will not stay centered & decreases tube life.

Turn the feed rate control counterclockwise to line up the flat side of the motor shaft (d shaft) with the flat side of the spider in the feed rate control and push towards the motor.

  • Page 15: Pump Tube Basics

    Pump Tube Basics The tube is the workhorse of the pump and is perishable. It will eventually reach the end of its service life, indicated by: The very first tube replacement indicates the expected service life for the tube & the specific application if other conditions are not the cause. Before tube replacement, confirm if the tube reached its expected life or correct what has caused reduced service life.

  • Page 16: Maximize Tube Life

    Maximize Tube Life DO NOT use pliers to secure connections or ferrules can be damaged. The 1/4" connecting nut must be finger tightened only. DO NOT pull on the tube fittings to stretch the tube. Follow instructions in the manual to run the roller assembly in the collapsed position 4 minutes to relax tube.

  • Page 17: Visual Reference

    Visual Reference When the tube is pressed against the tube housing wall, the shape formed can be used as a visual reference. A tear drop pattern is normal and confirms the roller assembly has been expanded after tube replacement. A diamond pattern indicates excessive back pressure. Excessive back pressure is caused by any blockage, or a clogged duckbill or when the system pressure exceeds the tube pressure rating.

  • Page 18: Poor Conditions Reduce Tube Life

    Poor Conditions Reduce Tube Life SEIZED ROLLERS Chemical exposure allows corrosive chemicals to collect on the roller bushings causing rollers to seize. Seized rollers stretch and pull instead of smoothly rolling over the tube. SOLUTION Confirm chemical compatibility with housing and tube material. Review factory installation instructions.
  • Page 19 Poor Conditions Reduce Tube Life EXCESSIVE BACK PRESSURE AT THE POINT OF INJECTION DISCHARGE LINE Calcium or mineral deposits in the injection fitting can cause blockage or restriction creating back pressure exceeding the tube pressure rating. SOLUTION Insert #2 Phillips head screwdriver through injection fitting into the pipe to break up accumulated deposits.
  • Page 20 Poor Conditions Reduce Tube Life SPLIT ALONG SIDE OF THE TUBE If the tube is not centered and it continuously rides against the edge of the tube housing, it will split. SOLUTION Always follow the tube replacement instructions in the manual which includes centering the tube. NOTE: The tube will not center if it is twisted during installation or if the rollers are worn.

  • Page 31: Feed Rate Control

    Feed Rate Control Basics The Feed Rate Control (FRC) adjusts the Dial Ring Setting pump output by utilizing a cam & spring loaded lifter assembly to control the rotation of the roller assembly according to the setting on the dial ring. The dial ring setting controls the amount of cam in the channel.

  • Page 32: Feed Rate Control Wear

    Feed Rate Control Wear Worn parts affect dosing accuracy. Check the Worn groove in parts for wear if the feed rate control makes plastic cam a skipping or ratcheting sound and/or the flow rate output is less than the setting. At the lower settings, the lifter rides on a large section of the cam and will wear a groove in the cam.
