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
Pumps may also be provided with outboard ball bearing, tang shaft, relief valve and choice of Buna N, neoprene, Viton or EPR seal.
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.
