All ChemFlo end suction centrifugal pumps have a cast 316 stainless steel housing, seal housing, impeller, pump shaft or a motor shaft sleeve. All use a type 2100 carbon/ceramic/viton seal with viton o-ring. The ChemFlo series of pumps are designed to be applied in a wide range of pumping applications where stainless steel is required. The ChemFlo pumps utilize a semi-open impeller design to allow for passage of larger solid sizes than similar sized enclosed impellers. ChemFlo pumps are offered in two configurations, pump (with motor) and PumPAK (without motor) versions.
