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.
