Pump Maintenance
Lubricating the Pump
Pump lubrication is the most important part of regular pump maintenance. Proper lubrication
ensures long service life, smooth flow performance, and protection against corrosive lab fumes.
The pump may not be adequately cleaned and lubricated if the following occur: (1) grinding
sounds are coming from the lead screw; (2) the block release button decouples under the load
before the pump stalls; or (3) the pump stalls with increased frequency.
Lubrication Instructions
1. Clean contact surfaces with a clean cloth. Remove any debris on the lead screw and the
guide rods.
2. Apply lubricant along the length of the lead screw and the guide rods.
3. Press the block-release button and slide the pusher block to the left edge.
4. Run the pump end-to-end without a syringe to work the lubricant into the components.
Pump lubrication should be performed every three months.
