Quad Sensr VSD .5 hose barb

Model Number
Flojet R4400-503 Quad Sensr VSD .5 hose barb
Flojet’s quad Variable Speed Drive (VSD) system needs no accumulator tank. Its microprocessor provides precise speed control to match the system demand. As more water is needed, the motor drives the pump for more flow. As the demand lessens, the motor slows to a super-quiet speed, yet maintains a steady pressure. The result is an unbelievably home-like flow. This smooth performance from no flow to maximum flow is sensor controlled, without any cycling. The system is free of pulsation and water hammer. Amp draw reduces as flow reduces to conserve energy, ranging from less than 1 amp to a max.of 10 amps. Self priming up to 8’.Automatically adjusts to 12V or 24V input. Thermal overload protection with auto restart. VSD automatically shuts off if supply voltage falls below 8 volts to protect the vehicle battery. Intermittent duty cycle.
