VF63BS-R (automatic relay pump)

Tohatsu VF63BS-R 4-stroke automatic relay pump, the successor to the world's first automatic relay pump: when water from the master pump reaches it, the engine and pump start automatically and stop automatically when the water stops, so no operator is needed at the relay pump and the relay line can be extended without limit for forest and wild-land fires and long-distance water transfer. Pump performance 1,200 l/min at 0.6 MPa, 950 l/min at 0.8 MPa and 700 l/min at 1.0 MPa; 500 mL 4-stroke engine, 22 kW, dry weight 84.5 kg.
