Centrifugal Truck Pump is a kind of centrifugal pumps, which is ideal for many agricultural and industrial uses. These pumps consist of a set of rotating vanes, enclosed within a housing or casing, used to impart energy to a fluid through centrifugal force. The centrifugal truck pump design requires that pump and motor be mounted at base of tank which doesn't leave quite as much room in the bed of truck as the diaphragm pump system. The pump has two main parts a rotating element which includes an impeller and a shaft and a stationary element made up of a casing, stuffing box and bearings. Centrifugal truck pumps operate using kinetic energy to move fluid utilizing an impeller and a circular pump casing. The impeller produces liquid velocity and the casing forces the liquid to discharge from the pump converting velocity to pressure. This is accomplished by offsetting the impeller in the casing, and by maintaining a close clearance between the impeller and the casing at the cutwater. The fluid enters the pump near the center of the impeller and is moved to its outside diameter by the rotating motion of the impeller. The vanes on the impeller progressively widen from the center of the impeller that reduces speed and increases pressure. This allows centrifugal pumps to produce continuous flows at high pressure. By forcing the fluid through without cupping it, centrifugal pumps can achieve a very high flow rate. These pumps are also suitable for lawn spraying and watering applications.
