The Pondmaster 2100GPH Hy-Drive pump comes encased in a durable outer chassis & utilizes a heavy duty rotor which enables the pump to move greater volumes of water through larger tubing diameters. It is designed to be positioned standing up or lying down in a skimmer, a pump bag or may be converted to an 'in-line' system. The Pondmaster 2100 Hy-Drive is repairable & also comes with a 18 foot power cord and a 3 year warranty.
