WARRANTY

9.1 

Limited Warranty

Your Blue-White product is a quality product and is warranted for a specific time from date of purchase (proof of purchase is required). 
The product will be repaired or replaced at our discretion. Failure must have occurred due to defect in material or workmanship and not 
as a result of operation of the product other than in normal operation as defined in the product manual. Warranty status is determined 
by the product's serial label and the sales invoice or receipt. The serial label must be on the product and legible. The warranty status of 
the product will be verified by Blue-White or a factory authorized service center. 
CHEM-FEED® MD3 pumps are warranted for 5 years from date of purchase (proof of purchase is required). Pumps will be repaired or 
replaced at our discretion. 

9.2 

DIAFLEX  Warranty

®

DIAFLEX® diaphragms are warranted for the life of the pump. Blue-White will replace a damaged diaphragm at no cost to the customer 
provided the pump was at all times operated within the guidelines included in the pump's operation manual. This warranty only applies 
to DIAFLEX® diaphragms, not the pumps themselves. Blue-White pumps are separately covered by warranties specific to them.

Blue-White does not assume responsibility for any loss, damage, or expense directly or indirectly related to or arising out of the use of 
its products.  Failure must have occurred due to defect in material or workmanship and not as a result of operation of the product other 
than in normal operation as defined in the pump operation manual.

The warranty status is determined by the pump's serial label and the sales invoice or receipt.  The serial label must be on the pump and 
be legible.  The warranty status of the pump will be verified by Blue-White or a factory authorized service center.

9.4 

Procedure for In-Warranty Repair

Warranty service must be performed by the factory or an authorized service center. Contact the factory or local repair center to obtain a 

RMA (Return Material Authorization) number. It is recommended to include foot strainer and injection/check valve fitting since these 
devices may be clogged and part of the problem. Decontaminate, dry, and carefully pack the product to be repaired. Please enclose a 
brief description of the problem and proof of purchase. Prepay all shipping and insurance cost. COD shipments will not be accepted. 
Damage caused by improper packaging is the responsibility of the sender. When In-Warranty repair is completed, the factory pays for 
return shipping to the dealer or customer.

9.5 

Product Use Warning

Blue-White products are manufactured to meet the highest quality standards in the industry. Each product instruction manual includes a 
description of the associated product warranty and provides the user with important safety information. Purchasers, installers, and 
operators of Blue-White products should take the time to inform themselves about the safe operation of these products. In addition, 
Customers are expected to do their own due diligence regarding which products and materials are best suited for their intended 
applications. Blue-White is pleased to assist in this effort but does not guarantee the suitability of any particular product for any specific 
application as Blue-White does not have the same degree of familiarity with the application that the customer/end user has. While Blue-
White will honor all of its product warranties according to their terms and conditions, Blue-White shall only be obligated to repair or 
replace its defective parts or products in accordance with the associated product warranties.

 BLUE-WHITE SHALL NOT BE LIABLE 

EITHER IN TORT OR IN CONTRACT FOR ANY LOSS OR DAMAGE WHETHER DIRECT, INDIRECT, INCIDENTAL, OR 
CONSEQUENTIAL, ARISING OUT OF OR RELATED TO THE FAILURE OF ANY OF ITS PARTS OR PRODUCTS OR OF THEIR 
NONSUITABILITY FOR A GIVEN PURPOSE OR APPLICATION.

9.6 

Chemical Resistance Warning

Blue-White offers a wide variety of wetted parts. Purchasers, installers, and operators of Blue-White products must be well informed 
and aware of the precautions to be taken when injecting or measuring various chemicals, especially those considered to be irritants, 
contaminants or hazardous. Customers are expected to do their own due diligence regarding which products and materials are best 
suited for their applications, particularly as it may relate to the potential effects of certain chemicals on Blue-White products and the 
potential for adverse chemical interactions. 

Blue-White tests its products with water only. The chemical resistance information included in this instruction manual was supplied to 
Blue-White by reputable sources, but Blue-White is not able to vouch for the accuracy or completeness thereof.  While Blue-White will 
honor all of its product warranties according to their terms and conditions, Blue-White shall only be obligated to repair or replace its 
defective parts or products in accordance with the associated product warranties.

 

BLUE-WHITE SHALL NOT BE LIABLE EITHER IN TORT OR IN CONTRACT FOR ANY LOSS OR DAMAGE, WHETHER DIRECT, 
INDIRECT, INCIDENTAL, OR CONSEQUENTIAL, ARISING OUT OF OR RELATED TO THE USE OF CHEMICALS IN 
CONNECTION WITH ANY BLUE-WHITE PRODUCTS.
