Tuthill lubrication and circulation pumps handle many viscosities and sustain a constant flow at any pressure. With only two moving parts the internal gear design allows the pump to handle higher viscosity liquids. Simple, Compact Design offers high efficiency and longer life. Positive Reversing Action - The unique reversing feature allows the lubrication and circulation pumps the ability to reverse flow without the use of valves.

Model: 1000, 1008, 1010, 1012, 1017, 1018, 1024
1000 Series pumps are based on the proven internal gear principal, but have been enhanced in response to demands from our OEM customers for a pump that offers advanced features which make installation easier. These side-ported pumps have the option to bolt SAE/DIN flanges onto them ensuring maximum flexibility on the porting arrangements. Our goal was to design a pump that meets your technical requirements and is easily fitted into your system.

TUTHILL SERIES 4100
Series 4100 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 4300
Series 4300 pumps are provided with mechanical face type seals. Ten models provide capacities from 6 to 84 GPM. Series 4300 pumps are supplied with Woodruff keyway shafts. Pumps may be provided with outboard ball bearing, relief valve and choice of Buna N, Neoprene, Viton or EPR seal. An optional mounting foot is also available

These pumps are capable of handling inlet pressures to 250 psi at standard 1750 rpm motor speeds. Maximum discharge pressure capability is 300 psi. Maximum differential pressure capability is 150 psi.
