CB+216M Explosion Proof Portable Pump Assembly

The CB+216MD Explosion-Proof Portable Pump Assembly is a sanitary transfer pump designed for moving flammable liquids safely. It combines a CB+216 pump head, an explosion-proof motor, and an explosion-proof motor starter on a stainless steel cart, so the whole assembly moves easily between tanks. The explosion-proof motor makes the pump suitable for high-proof alcohol, ethanol, and other flammable liquids, and ideal for distilling, producing alcohol-blended drinks, and herbal extraction. The CB+216 pump head, a redesigned C-Series pump with an internal mechanical seal, is also well suited to Clean-in-Place (CIP) and product transfer applications in the food and beverage industries. 

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). The motor is controlled by a Killark B7MS Series explosion-proof motor starter. The cart is sized to the pump: a medium duty cart for 3 HP, a heavy-duty cart for 5, 7.5, and 10 HP, and a super heavy duty cart for 15 HP. 

All pumps come standard with 2" x 1.5" Tri-Clamp connections. Explosion-proof pump assemblies are supplied without an electrical plug. The appropriate plug must be installed in accordance with applicable electrical codes and local regulations. 

Key Features: 

The CB+216MD Explosion-Proof Portable Pump Assembly combines the CB+216 pump head with an explosion-proof motor, motor starter, and cart, 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. 
  
• Start, stop, and lock out the pump with a Killark explosion-proof motor starter. 
  
• Move the assembly between tanks and work areas on a stainless steel cart.
