Ideal for larger fenders among other high-volume inflation needs, the Fendertex Large Volume Turbine Pump is a high output option capable of 5.8 psi of max pressure. This pump utilizes a main motor that can be run independently, along with an additional booster motor to increase flow rate and pressure. Its green button powers the main motor, while red button powers the secondary motor, making for easy operation. Both motors are protected by thermos-amperometric fuses, giving you greater piece of mind. The unit itself runs on 110v and can easily be stored in boat lockers and other accessory hatches.
