Services
• Fiberous Wastewater
• Industrial Process
• Industrial Sump Wastes
• Tank Unloading
• Corrosive and Non-Corrosive Liquids
• Food Processing
• Chemical SlurriesThe CV 3171 is a recessed impeller, circular volute type sump pump. Ideal for large solids and shear sensitive fluids. It will pass any solid that will pass through the discharge pipe. Circular volute minimizes radial loads, making this the ideal pump for low flow process applications.

CV 3171 Vertical Sump and Process Pumps
LABYRINTH BEARING SEAL Prevents premature bearing failure due to lubricant contamination
C-FACE MOTOR MOUNTING Accommodates readily available C-face motors. Also available for P-base and IEC motors.
CONTINUOUS HIGH PERFORMANCE Original high efficiency maintained by simple external adjustment resulting in long-term energy savings
DOUBLE ROW THRUST BEARING Grease lubricated – carries pump thrust load, sealed for outdoor installation
DISCHARGE LOCKED TO PUMP SUPPORT PLATE FOR STRENGTH
ANY MOUNTING REQUIREMENTS Met by support plate and optional pit cover. Float switches, alternators and other control devices can be easily mounted
STEADY BEARING HOUSING Precision machined register fit of column, bearing housing and casing assures positive bearing and shaft alignment. Completely interchangeable with all lineshaft bearing options
HEAVY DUTY ONE-PIECE SHAFT With closely spaced steady bearings assures long life and low maintenance
NON-CLOG CIRCULAR CASING Large open passageways prevent clogging when handling bulky, fibrous, or stringy liquids. Circular Volute reduces radial loads during low flow operation, extending steady bearing life.
OPTIONAL UPPER STUFFING BOX
RECESSED IMPELLER Since impeller is recessed in the casing, velocities are low and solids contact with the casing are reduced. Wear rate, solids degradation, and shearing of liquids are minimized
OPTIONAL STRAINER Recommended for services where solids larger than the discharge of the pump can potentially enter the casing.
HEAVY COLUMN PIPE Provides rigid support for pump and bearings
LINESHAFT STEADY BEARING Grease lubricating sealed bearings furnished as standard – best for handling fluids with solids
RESTRICTOR BUSHING Close running bushing to prevent pressure loss from casing
