CHEMFLO® 4 HYDRAULIC
2" x 1-1/2" End Suction Centrifugal Pump
Made with high quality investment cast 316 stainless steel components, 
the ChemFlo® series of pumps are designed to be applied in a wide range 
of pumping applications where stainless steel is required.
The ChemFlo 4 hydraulic pumps utilize a semi-open impeller design to 
allow for passage of larger solid sizes than similar sized enclosed 
impellers. Several seal options are available in additon to the standard 
type 2100 carbon / ceramic / Viton mechanical seal.
ChemFlo® 4 hydraulic pumps are offered with .22 or .37 cubic inch 
displacement gerotor motors for hydraulic flows up to 10 GPM and a 
maximum pressure of 2500 PSI.
Further expanding the versatility of the ChemFlo® series is the CFB 4 
pump, a ChemFlo® 4 in NiBrAl material. All wetted parts are produced in 
CA 958 nickel aluminum bronze including the drive sleeve to maximize 
corrosion protection in seawater applications.
