Values shown are based on fluid viscosity of 100 SUS (20 cSt) mineral oil, except pumps for water-based fluids as indicated.
Inlet pressures higher than 10 psig (0,7 bar) require a high-pressure shaft seal.
Minimum inlet pressure: 5 psi (0,4 bar) at 2200 rpm.
Minimum inlet pressure for Model PF3011: 5 psi (0,4 bar) at 2200 rpm and 7 psi (0,5 bar) at 2500 rpm; for Models PF3015 and PF3021: 7 psi (0,5 bar) at 2200 rpm
Minimum inlet pressure for Models PF6070 and PV6070: 10 psi (0,7 bar) at 2300 rpm maximum speed; for Model PF6080 and PV6080: 15 psi (1,0 bar) at 2200 rpm
Values shown are based on fluid viscosity of 33 SUS (1,9 cSt) water glycol fluid. Higher viscosity fluids may require pressurized inlet conditions then indicated.
