Corken’s CP-model pumps are ideal for petroleum products with low vapor pressures such as petroleum based oils, fuel oils, lube oils and thin liquids such as alcohols and solvents. These pumps utilize gasket and O-ring construction and feature a adjustable internal relief valve. Multiple mechanical sealing options are available.

Flow rates up to 400 gpm (1,514 l/min)
Working pressures up to 200 psi (13.8 bar)
Differential pressures up to 125 psi (8.6 bar)
Temperature range: -25 to 225 °F (-32 to 107 °C)
Viscosities up to 20,000 SSU (4,250 cSt)

• Multiple pump sizes
