The four-vane Series RI pump is the most effective when pumping medium to high viscosity liquids. Larger porting and pumping chamber provide maximum filling and flow capability while heavier vane construction gives greater shear strength.
Series RI non-metal fitted pumps are inherently self-lubricating, and the total area of contact between moving parts is significantly smaller which lowers mechanical friction losses. With a shorter, simpler flow path; simpler parts and larger chamber cause less shear or turbulence, this lowers hydraulic friction and shear loses. Liquid slip losses are lower due to dynamic vane actuation and self-adjustment for wear. Pump speeds are lower due to high volumetric displacement. Volumetric efficiency losses are lower due to self-adjustment of vanes.
The vanes in Series RI are self-adjusting for wear. This allows the pump to maintain volumetric efficiency while wear seriously reduces capacity of other rotary pumps. A foster pump does not require replacement, increased speed, and power, or more frequent repairs to maintain capacity.
Maintenance-In-Place makes reconditioning easy and economical. New vanes are often all that’s needed to be replaced. Even extensive wear is no problem. All wear parts can be replaced without dismounting the pump or disconnecting system piping. No specials tools or skills are needed.
Series RI can be equipped with a Pressure Limiting Valve (PLV), which an adjustable spring-loaded poppet valve is designed to freely bypass full pump flow if the pump discharge line is closed or restricted within viscosity limits. The internal bypass PLV returns discharged liquid to the pump inlet for automatic bypass protection with no need for external piping. The convertible PLV permits selection of either internal bypass or return to source through external piping, depending on which of two valve discharge ports is closed off.
Series RI has a flow rate up to 1000 gpm (4,546 lpm) and a pressure rate of 250 psi (17.24 bar).
Series RI has two standards and one special alloy, from cast iron, ductile iron, and 316ss that are available.
