Some info from EcoTech that I thought was worth sharing....
New study proves that the 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 in this month's edition of Advanced Aquarist.
Dr. Sanjay Joshi, Ph.D., professor of Industrial and Manufacturing at the Pennsylvania State University, conducted the study. He used a proven method to most accurately determine the output flows 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 GPP - 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, ideally suited for larger tanks, has an advertised rate of 7500 GPH. It delivered 8509 GPH in the controlled study - an increase of 13.5%.
