Frequently Asked Questions

Ezi-action® Drumpump seals are made from LDPE plastic which has excellent chemical resistance and are well proven.

The addition of an OR -116 Brown Viton O ring above the LDPE seals on the plunger shaft can be beneficial when the Ezi-action® Drumpump is being used to pump large volumes. It can also be useful when there is an increase in back pressure because the pump is being used to pump fluids against gravity or when the fluids are very viscous.


OR-116 Brown Viton O rings can be bought locally or we can supply them if you prefer.



Yes. If a long hose is fitted and siphoning is not desired this can be easily managed.

To break the siphon air needs to enter the hose, the hose needs to be crimped and/or the hose needs to be stored higher than the contents of the drum. Removal of the long hose from the Ezi-action® Drumpump when not in use will prevent unintentional siphoning as will removal of the Ezi-action® Drumump from the drum when not in use.

We offer a polypropylene non-return check valve with a viton seal. This can be fitted to a hose and will prevent siphoning as it permits air to enter the hose.

Contact us if you are interested in a non-return check valve as an accessory.


Yes. The Ezi-action® Drumpump will act as a siphon pump. However it will operate as a siphon only when a long hose is fitted and providing the source of the fluid is higher in elevation than the receptacle.
