“We purchased a Chinese wiped-film evaporator, which included gear pumps for feed & discharge.  The pumps were terrible quality, frequently ceasing, and were extremely difficult to disassemble and clean.  On our first Mahr pump, we could see the difference!  The pump works flawlessly, not stressing the motor either – just smooth spinning and pumping of liquid.  We got the DLC finish and already have seen longer lifespans from Mahr’s pumps.  Oh, and they are half of the cost of the Chinese pumps!  Thanks for everything, Mahr!”

“We were introduced to MAHR in Germany via a chemical supplier who recommended their technology.   Having purchased several systems from the Charlotte location, we can highly recommend the company.  Top-quality with full customization available.  This is now our preferred supplier for pumps and metering.”
