How To Pump Ethanol - Tips And Tricks From The Experts

Hand-sanitizer

All Pumps have been specialists in the Hygienic and Chemicals Industries Since 1972. Ethanol Pumps for manufacturing hand sanitiser and similar products are part of our mainstream range. We stock hazardous area rated Air Pumps and Electric Pumps for unloading Ethanol.
There are a few key requirements when looking at a pump for ethanol and we strongly recommend speaking to our specialists prior to purchasing:

Hazardous / Dangerous / Flammable Goods Rated

  • Ethanol is highly combustible and will ignite from a static spark charge if the incorrect pump is selected.
  • The pump needs to be of a conductive material and have Certificate in the case of a motor IECEx ratings to ensure the pump can be grounded properly to minimize any risk of a fire.
  • Grounding your pump is very important. When your pump is portable it is best to have designated grounding points which allow the pump to be securely grounded while running.

Power Source Available

  • This is straight forward, if you have a good sized compressor onsite and wish to spend as little as possible on your plant up front go with an air operated pump
  • If your plant doesn’t have air available you will need to look at the electric options.

Application for Use

  • If you are decanting a 205-litre drum or a 200,000 litre tank the pump needed for the job will be very different.
  • For decanting 205-litre Drums we recommend using a Drump Pump with an Explosive rated motor and seals for ethanol.
  • For pumping from 1000 litre totes or IBC’s we recommend using a small air operated diaphragm pump or vane pump.
  • For larger bulk tanker unloading applications we recommend using a larger Air Operated Diaphragm Pump, 2 inch or 3 inch, or a Larger Vane Pump.
  • If your application is going to be permanent or a high use application, we would recommend you look at the Electric Diaphragm Pumps or Vane Pumps so you reap the energy saving benefits.

Chemical Compatibility

  • We strongly suggest using Stainless Steel pumps with PTFE seals and elastomers when possible.
  • Some plastic pumps are suitable if the plastic is conductive.
  • The Stainless Casing will provide durability and chemical resistance for other chemicals should your use change in the future.
  • Some hand sanitisers contain small amounts of acids which can attack Aluminium or other metals.
  • For elastomers, ethanol is aggressive and will eat out standard rubbers. We strongly recommend PTFE or VITON Elastomers.

Ethanol / Hand Sanitiser is in high demand and so are pumps.

All Pumps have a global supply chains and are committed to keeping a good number of pumps in stock for these applications to help anyone who can make the product fight the current crisis.
