Proper Pump Storage
Long Term Storage
Before leaving your IPM pump in storage for an extended period of time, it is important to flush the reactive material out of the pump with a proper solvent and purge with a quality storage fluid. Typically, it will be a Glycol Ether based solvent, completely moisture free. Check with your chemical supplier to make certain of compatibility.
Once the pump has been properly flushed, follow with the proper storage fluid. The storage fluid should be completely moisture free as well and is typically a plasticizer that will not gel or react with any trace chemicals left in the pump. A good example would be DOP (Dioctyl Phthalate).
It is recommended that the transfer pump be stored in an upright position in a PVC sleeve containing clean pump lube. This PVC sleeve should be fitted with a bung adapter so that the transfer pump can be locked into position and kept airtight.
Helpful Tips for Making Your Pump Last Longer
- Frequently service your pump throughout the year to ensure all parts are working as intended.
- A good oiler, water/debris separator and/or air-drying system is heavily recommended for each transfer pump in use.
- Make sure that the supply air line is at least 15 feet (4.5M) long, before connecting to your air/water separator. This will give the moisture in the air line time to cool off and condense into water droplets where it can be captured by the separator. This is also true for mixers if you are using one.
- At the end of the workday, where possible, do not leave piston rods exposed to air. Make sure pistons have been left in the bottom most position in the pump- this will help protect the seals from getting shredded when you start the pump up the next day.
- There is no rule of thumb for replacing fluid section or air section seals. If properly maintained, they can last for quite some time. Keep one of each kit for use as spares in your toolbox. Also highly useful to have is a conical spring for the air cylinder cap. Running your pump dry with no product tends to severely affect this part. Extra square cut gaskets for the bung adaptor are an inexpensive way to ensure continued operations as well.
- Synthetic lube (no water content) should always be in your toolbox for lubing the A-side threads of the bung adaptor.
- When installing either a new air section kit or a fluid section kit, remember that there are videos available to help you. Pay attention to torque specs in the manual.
- Do not forget to apply Loctite to the indicated parts highlighted in your pump manual when rebuilding the pumps.
- Never use the pump as a handle when trying to move a drum.
- Ensure the pump is properly flushed and lubricated before each use with a new chemical.
- Do not under any circumstances leave the A-side pump out of the drum and exposed to air for any period of time, it will crystallize and render the pump useless overnight.
- At least one extra material supply hose for the A-side should always be on your rig.
- At least one spare transfer pump per every pump in service should be maintained, and properly stored (see long term storage section). Under no circumstances should a reserve B side pump be used on the A side- as you can never really remove all chemicals from the pump interior.
