Flo-Master Pumps are designed with a unique, high-performance impeller providing flow rates that exceed all tested competition. Ideal for larger, multi-jetted tubs or similar applications requiring greater output. Each pump is engineered with careful attention to detail and accuracy. In many applications the outstanding flow rates will allow you to use a lower H.P. pump to do the same job. Less H.P. means lower operating costs. QUICK RELEASE compression fittings allow for easy installation or maintenance. Aqua-Flow’s drip proof, cool running seal virtually eliminates seal burnout.
