Achieving Optimum Balance for Maximum Value L & C S E R I E S P U M P S L & C Series Pumps’ SIMPLE, COMPACT DESIGN offers high efficiency and longer life. THE PUMPING PRINCIPLE Tuthill L & C Series cast iron pumps employ the internal gear pumping principle. There are only two moving parts. Pumping action is based on a rotor, idler gear and a cover cast with a crescent-shaped partition. 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. 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. When the teeth mesh on the pressure side, the liquid is forced from the spaces and out through the discharge port. 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. When shaft rotation changes from clockwise to counter-clockwise, the idler carrier (including the idler gear and crescent) automatically rotates 180º through the suction zone to the position shown in the drawing above. This changes the direction of the flow within the pump without changing port positions. On resumption of clockwise rotation, the crescent will swing back to the original position. www.tuthillpump.com This design allows the pump to handle a wide range of viscosities while sustaining a constant flow regardless of pressure. The non-pulsating flow also runs substantially quieter than other pump designs. With minimal to moderate wear, our internal gear pumps outperform other pumping technologies.
