Help extend the life of your dosing pumps head by adding a few small drops of lubricant every few weeks. Most dosing pumps either have a loose cap over the roller head holding in grease or they have a self lubricating tube, and over time both the grease or the tube will wear out. By adding Dosing Tube Lubricant to your dosing pumps rollers and tubing you can greatly increase the lifespan of the tubing and entire pump.
