How long has EcoGreen Industries been working in the extraction industry?

EcoGreen Industries was founded in 2013 as a direct gas supplier. Our extraction experts are the most trusted, most professional, and most knowledgeable in the industry.

Why did my CMEP-OL arrive without an electrical plug?

To meet the criteria of “explosion-proof,” our CMEP-OL pump is able to contain any explosion originating within its housing. This prevents sparks from within its housing from igniting vapors, gases, dust, or fibers in the air surrounding it. The CMEP-OL wiring also meets international explosion-proof standards as it is additionally designed to be hard-wired into your power system to avoid any possible spark created when plugging in and unplugging it. Please note that the blue wire is the ground wire, the black wire is the hot wire, and the brown or purple wires are your neutral wires.

How often should I perform maintenance on my CMEP-OL pump?

The CMEP-OL manufacturer recommends periodic top-end rebuilds. This process involves cleaning the cylinder heads, replacing the pistons and various gaskets, and performing a few more minor procedures (when required). Please see the owner’s manual for specific details.

We recommend that you install a new rebuild kit within every 200 hours of proper use. If you begin to notice that your recovery rate is decreasing before reaching the 200-hour mark, this is an indication that you may need to install the rebuild kit a bit sooner. Please see our video for guidance on how to perform the rebuild kit installation.

What is covered if my CMEP-OL pump has issues or is faulty?

The customer covers all of the related shipping costs when sending a pump to and from our location. If it is determined that the pump failure was covered under the manufacturer’s warranty, we will cover the cost of labor and parts.

What does it mean if I hear a squealing sound when running my CMEP-OL pump?

The most common reason here would be because the internal bearings are failing. You may either purchase a Master Rebuild Kit, get the needed individual parts separately, or call us for more information on how our service department can service the pump.

Why is my CMEP-OL pump not building any pressure?

The two most common reasons for this operational condition are a damaged cylinder or head intake valve. Another common reason is that the pressure test is not being performed according to the manufacturer’s recommendations. Please see the owner’s manual for how to properly test the pump’s ability to hold pressure, located in the “Gas Leakage Inspection” section. Contact us if you still have any questions regarding this.

How do I clean my CMEP-OL?

For disassembled parts, use denatured alcohol and a clean cotton towel to wipe off dirt and any grimy residues that you may see. For pumps that are still hooked up to a system, complete a dry run using one of the recommended solvents. Be careful with the CMEP-OL wiring.

What solvents are the CMEP-OL pump designed to be used with?

The CMEP-OL is specifically designed to be used with N-butane (R600), Isobutane (R600a), Propane (R290), and any combination of these.

Do you offer classes or instructions on how to repair the CMEP-OL pump?

We do provide an instructional video on how to perform a top-end rebuild procedure, but we currently do not offer any instructional classes or on-location training. We do, however, highly recommend having our service department work on your pump. Our technicians work on pumps every day and do have specific skills for optimum running performance. If you have further questions regarding this pump, you can submit your questions via the Contact Us page.

Where can I submit my warranty card?

In order for your warranty to become active, you must first submit your warranty card to cs@chinachunmu.com. Please take note that you are submitting your warranty card directly to the CMEP-OL manufacturer and not to EcoGreen Industries, LLC.

Where do I submit service requests and repair questions?

You can contact us via email or by calling us directly at 530-378-4443 during our business hours.

Do I need to authorize pump repairs?

In order for your warranty to become active, you must first submit your warranty card to cs@chinachunmu.com. Please take note that you are submitting your warranty card directly to the CMEP-OL manufacturer and not to EcoGreen Industries, LLC.

Can my limited warranty be voided?

The most common situations that occur that void the limited warranty is when the material is sucked into the pump, when periodic rebuilds are not performed (150-200 hours of use), when the pump experiences sudden pressure spikes, and when more than just the top-end rebuild maintenance procedure is performed.

This limited warranty is also voided when:

  • the product or product part is broken by accident;
  • the product is misused, tampered with, or used with any accessories that are not manufactured by CM but furnished with CM products;
  • the product is used for recovering any substance other than the specific refrigerant type;
  • the product is not purchased from EcoGreen Industries LLC;
  • the customer has not completed the warranty registration.

What does the manufacturer’s limited warranty cover?

As of March 2017, customers who purchased the CMEP-OL from EcoGreen Industries LLC and have submitted their warranty registration directly to the manufacturer will be in accordance with the one-year warranty policy.

The CMEP-OL is warranted to be free from defects in workmanship, materials, and components for a period of one year from the date of purchase. Please note that some parts are not covered by this limited warranty and will need to be replaced when worn. These parts that are not covered are the bearings, piston rings, shaft seals, cylinder head suction and discharge valves, and casters.

The limited warranty is only for the original buyer who completes the warranty registration and purchases the machine from EcoGreen Industries LLC.

The manufacturer shall not be responsible for any additional cost associated with product failure including, but not limited to, loss of work time, loss of refrigerant, and unauthorized shipping or labor charges.

All warranty service claims must be made within the specified warranty period. Proof-of-purchase date must be supplied to EcoGreen Industries LLC.
