Since the 1940s, Viking Pump's Universal product line has undergone four generations of engineering improvements – making upgrades to evolve with changing customer needs while preserving the features and reliability of the original design. The result has been a product line where customers running decades-old equipment can easily upgrade to the latest technology without redesigning their entire system. That backward compatibility has been the guiding principle of almost every design decision over the decades.
