TUTHILL SERIES 4100 Lubrication Pump
Tuthill 4000 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 crescentshaped partition cast integral with the cover. Power applied to the rotor is transmitted to the idler gear with which it meshes. The space between the outside diameter of the idler and the inside diameter of the rotor is sealed by the crescent. 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 teeth of the idler and the rotor 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.
Description
Tuthill Series 4100 lubrication pumps have optional foot mounting, but can also be provided for close coupling and adapter mounting. They have an open-coring design which provides outstanding performance at higher speeds and pressures. The selection includes models with capacity range from 1/3 to 14 GPM. Rotor heads are hydraulically balanced for minimum end clearance assuring excellent priming and consistent capacity over a wide viscosity and pressure range. These pumps are capable of handling inlet pressures as high as 250 psi at standard 1750 rpm rotor speeds, with maximum discharge pressures to 300 psi.
Tuthill Series 4100 pumps include a mechanical seal and carbon graphite idler and housing bushings. These pumps are compact, highly efficient, cast iron, positive displacement rotary pumps with mechanical seals and have been designed and manufactured to provide years of service under normal operating conditions
Pumps may also be provided with outboard ball bearing, tang shaft, relief valve and choice of Buna N, neoprene, Viton or EPR seal.
