C Series Circulation Pumps Unique Reversing Feature

This Tuthill innovation allows positive reversing action without the use of valves. Port positions remain constant regardless of the direction of shaft rotation. It is ideal for use in power transmission applications where the drive shaft direction changes, but the direction of flow must remain constant. Other applications where shaft rotation is unknown, the reversing feature allows the customer to specify the suction and discharge ports.

 

 Principle of operation of the Thai Khuong Pump C series tuthill gear pump
Principle of operation of the Thai Khuong Pump C series tuthill gear pump
(1) As the pump starts, the teeth come out of mesh, increasing the volume. This creates a partial vacuum, drawing the liquid into the pump through the suction port.
(2) The liquid fills the spaces between the idler and rotor teeth and is carried past the crescent partition through the pressure side of the pump.

(3) When the teeth mesh on the pressure side, the liquid is forced from the spaces and out through the discharge port.

When shaft rotation changes from counter-clockwise to clockwise, the idler carrier (including the idler gear and crescent) automatically rotates 180º through the suction zone to the position shown in the drawing below. This changes the direction of the flow within the pump without changing port positions. On resumption of counter-clockwise rotation, the crescent will swing back to the original position.
