Syringe Pump Maintenance

The most important thing to remember in laboratory syringe pump maintenance is to keep your system clean and properly lubricated. To ensure reliability and precision of your syringe pump, a few simple tasks will greatly prolong the service life and condition of your system.

Pump Cleaning

In a “bench top” lab environment, we recommend cleaning your instrument twice a year.

In a “fume hood” environment with corrosive fumes, you should clean your pump every two months. This is necessary to prevent damage to the lead screw and guide rods.

Cleaning Instructions

  1. Use a dry, clean cloth to wipe out any liquid spillage.
  2. Use a slightly damp cloth to clean up any dry dust.
  3. When not in use, keep the syringe pump covered to avoid dust accumulation on the lead screw and guide shafts.

Pump Lubrication

Proper lubrication ensures long service life and smooth flow performance while also providing protection against corrosive lab fumes and rust.

Usage Per Month

Lubrication Frequency

1-3Every 3 Months
4-6Every Month
7-9+Every Week

Note: If you are using the pump in high-pressure application, then daily pump lubrication is recommended.

  1. Clean contact surfaces with a clean cloth. Remove any debris on the lead screw and the guide rods.
  2. Apply the lubricant along the length of the lead screw and the guide rods.
  3. Run the syringe pump so that the pusher block moves across the entire length of the lead screw. This should work the lubricant into the grooves/components.

You should clean and lubricate the lead screw and guide rods based on your usage. Your pump may not be adequately 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.
  3. The pump stalls with increased frequency.
