CB+216M Pump With Explosion-Proof Motor

The CB+216M Pump with Explosion-Proof Motor is a sanitary centrifugal pump designed for medium-sized applications, including the transfer of flammable liquids. The CB+216 is a redesigned C-Series pump that maintains the reliability and durability of the C-Series while adding an internal mechanical seal. The internal seal allows the product to fully lubricate the seal during use and allows the Clean-in-Place (CIP) process to completely sanitize it. The CB+216 also features a drive collar that clamps evenly on all sides of the shaft and a threaded impeller nut that fully secures the impeller. Fitted with an explosion-proof motor and sanitary Tri-Clamp connections, the CB+216 is suited to CIP and product transfer applications involving flammable liquids.

The pump is paired with a cast iron, NEMA C-Face Premium Efficiency explosion-proof motor, UL/CSA approved for Class I, Groups C and D, and Class II, Groups E, F, and G (T3B). It is supplied as a pump and motor only, without a switch or cart. For a mobile, ready-to-move setup with a Killark explosion-proof motor starter, see the CB+216MD Explosion-Proof Portable Pump Assembly.

Key Features:

The CB+216M Pump with Explosion-Proof Motor combines the CB+216 pump head, a C-Series design with an internal cartridge seal, with an explosion-proof motor, allowing you to:

• Safely transfer high-proof alcohol, ethanol, and other flammable liquids with a UL/CSA approved explosion-proof motor.
• Keep the seal fully lubricated by the product during use.
• Completely sanitize the seal during CIP, with no pooling on the seal.
• Achieve greater seal pressure with less leaking.
• Rely on an encased cartridge seal that is more sanitary and less prone to breakage.
• Prevent shaft wobble with a drive collar that clamps evenly on all sides of the shaft.
• Secure the impeller with a threaded impeller nut.
• Clean behind the impeller during CIP, using two specialized gaskets that seal the shaft.
• Connect with standard 2" x 1.5" Tri-Clamp fittings.

Voltage Options:

The explosion-proof CB+216 is available in three-phase power and is compatible with 230V, 460V, and 575V. Single-phase motors are available for 1-1/2 HP as a special order. Contact us for a quote.

Horsepower Options:

Available from 1-1/2 HP to 15 HP, this pump can be matched to a range of transfer applications. For 15 HP motors, please contact our sales team. The 1-1/2 HP and 2 HP motors are 1800 rpm. Pairing a larger pump with a slower 1800 rpm motor provides gentle flow at high volumes; perfect for shear-sensitive products.
