Ezi-action® Drumpumps will dispense fluids of 8,800cps. They are proven to dispense honey (10,000cps at room temperature of 70F (21C)), molasses, oils: including coconut, olive and motor oils, shampoo, liquid soaps, gels......

Viscosity is measured at room temperature of 70F (21C).

The ambient temperature is important. 

In cold environments products can thicken and may not be able to be pumped or become much harder to pump as the fluid has to flow for Ezi-action® Drumpumps to work.


The table gives an indication of liquids that can be pumped with Ezi-action® Drumpumps:

Speed of Pumping

The pumping principle requires that the fluid fills up the inner chamber (plunger) and outer case pipe before flowing out the spout.

So, when the fluid is more viscous (thicker) it is slower to fill up and a few more priming strokes are required.
