New study proves that flow from the VorTech family of pumps exceeds even the company’s own advertised claims

EcoTech Marine, the company that revolutionized the reef aquarium propeller pump, is pleased to announce the results of a scientific study on flow rates published today in this month’s edition of Advanced Aquarist magazine.

Dr. Sanjay Joshi, Ph.D., professor of Industrial Engineering and Manufacturing at the Pennsylvania State University, conducted the study. He used a proven method to accurately determine the output flow of several leading aquarium propeller pumps. The study scientifically shows the entire VorTech line delivers superior flow rates far in excess of what EcoTech Marine itself was claiming in its own marketing and advertising.

The MP40, the VorTech that started it all, delivers 18.2% more than its advertised claim of 3200 GPH—netting 3781 GPH in the study.

The MP10, ideally situated for tanks smaller than 50 gallons, has an advertised flow rate of 1575 gallons per hour (GPH). The study showed a GPH of 2460—a 56.2% increase over the advertised amount.

The MP60, perfectly matched for the largest aquariums, has an advertised rate of 7500 GPH. It delivered 8509 GPH in the controlled study—an increase of 13.5% and unmatched by any other similarly sized pump in the industry

“At EcoTech Marine, we pride ourselves on delivering technologically superior products with exceptional value,” says Tim Marks, president of EcoTech Marine. “Using the most accurate equipment and technology possible to measure water flow, Dr. Joshi looked at a wide range of pumps from a variety of manufacturers. The fact the VorTech delivered superior results is a testament to our unrelenting commitment to engineering and manufacturing the most advanced products in the industry.”

In an effort to standardize the flow measurements and claims for aquarium propeller pump manufacturers, EcoTech enlisted the help of Dr. Sanjay Joshi to design an independent study utilizing the latest in analytical techniques available. To perform the study, Dr. Joshi used a Sontek 10-MHz Acoustic Doppler Velocimeter in a 350-gallon aquarium. The velocity profile of the pump exit flow was measured at a distance of one diameter downstream from the output of the pumps, and these measurements were used to determine the volume flow rate output.

“We’re very pleased with the results of the study,” said Marks. “The loyalty of EcoTech Marine customers has been rewarded. Reef aquarists purchase a pump for an expected performance, the most important of which is flow rate. We’d rather under-promise and over-deliver any day of the week to earn our customer’s loyalty.”
