HOW TO - Service a GHL dosing peri pump.
This is something we get asked all the time, can they be serviced and if so how?
Well the answer is yes as i will show with a step be step guide.
Peri pumps need servicing irrelavent of quality and we all know the GHL peri pumps are built to last, but to prolong the life even further I recommend following this proceedure every 6 months, this will reduce strain on the motor also
Step 1:
Unclip the Peri pump from the from of the doser, carefully pulling the pump off the motor shaft.
Step 2:
Turn assy on its back and note the upper and lower tabs
Step 3:
Gently press the upper and lower tabs inwards unclipping the pump cover and remove.
Step 4:
Remove the top roller support plate
Step 5:
Continue to remove the rollers and peri tubing taking care not to move the two black clips on the tube as these set the internal tube distance.
Step 7:
You are now presented with all the internal parts as shown
With a dry tissue clean off all the dirt from each component.
once clean, using vaseline, smear the smallest amount on the inside edge of the silicon peri tubing where the rollers run.
Now, on the 3 pronged roller location assy put a small amount of vaseline on each shaft.
Step 8:
Re- assemble in reverse order, but before closing the housing, press your finger in the center of the roller location plate and turn, making sure the assy is free and ready to run. Now close the rear plate.
You have now serviced your peri pump.
The pipe should not require replacement for the life of the unit.
All the above must be done with care as no self servicing is covered by GHL warranty.
