Why are “LORENTZ type” pumps offered from China at such low prices?

Over the past few months we have received many examples where “LORENTZ” or “LORENTZ like” products are being offered in the market. We have even been offered copies of our products to sell.
The degree of copying varies from simply copying our documentation but sending something different to some products which look quite similar.

We have been asked to provide a statement which covers off some frequently asked questions regarding design, manufacturing and supply of LORENTZ products.


LORENTZ manufactures our own products in our own factory. Companies that say they make our products for us are simply lying. Companies have been offering overstock, over production and cosmetically damaged good, none of these categories of product exist, we only sell new, perfect goods.

Marketing / trademarks / copyright

Many companies are using pictures of LORENTZ pumps and controllers in their marketing material. For most people this would be considered intellectual property theft. LORENTZ have spent significant amounts of money to get our name trademarked. Unfortunately in some countries these trademarks and our copyright is not respected and we cannot do anything to enforce this.


All of our distributors are listed on out Internet site www.lorentz.de, if you are being offered products from outside of this authorised distributor network then they are probably copies.


We have a very clear channel pricing model which allows all partners and LORENTZ an honest margin, if you are being offered products at significantly lower prices then there is a strong chance that they are not our products.

Quality costs money

LORENTZ design and manufacture our products using high quality materials. We have tested “similar” pump systems and quickly find the efficiencies are very poor and that ferrous materials are used in the submersible elements. While this reduces the cost the lifetime is very short, typically less than one year. A product that has the quality we offer cannot be produced for the selling price of some pumps being offered.

Investment in partners

LORENTZ are continually investing in our partner network. Tools such as COMPASS, infrastructure such as partnerNET and new channel and support staff all cost significant amounts of money. We hope you recognise and value this investment that we make to help you.

Warranty and liability

If you are considering importing “copy” products directly you should consider the warranty and liability implications. For many markets the liability for product safety and quality is the responsibility of the importer. If you are importing from a reputable company like LORENTZ the necessary certifications and warranty support are in place, for copy products this is not the case.

How we deal with the topic

LORENTZ takes this issue seriously, fake / copy products will damage the good reputation we have in the market and will cause lost sales for our partners. Where Approved LORENTZ partners knowingly handle fake goods or goods that are not purchased via approved channels then they will have their accreditation removed. We will continue to protect our partners and will do our best to stop copy products appearing that damages our mutual business opportunity.

If you are being offered products using our name or our product names then we would be interested in any material you have. Where possible we will challenge these companies through our lawyers.

Sharing information

If you see or are offered products that appear to be LORENTZ products but you are unsure then please contact us, we can easily check serial numbers and the source for you.

If you have information or experience with copy products that you would like to share with the LORENTZ partner community then please send it to marketing [at] lorentz.de and we will put it on partnerNET, you can remain anonymous if you would prefer.
