Additional pump models and hoses feature fire-hose-style quick-connect fittings, and a V-ring to protect the shaft seal from abrasives. They include a Deluxe Pump with 60-foot shut off head and a 110-volt, single-phase motor. A Standard model offers easy disassembly with one 12mm box/socket wrench.
