Features

CASING: Cast iron construction; tapped for drain, vent cock, and pressure gauge. Suction and discharge connections are standard ASA flanged type for easier installation. These pumps are of the back pull-out design to permit removal of all rotating parts without breaking suction and discharge connections. Casings are centerline discharge for automatic venting when used in the standard vertical discharge position. Discharge can be field rotated for 90 degree position changes.

IMPELLER: Single piece enclosed bronze casting, fully balanced with the diameter cut for specific condition points. Cast iron impellers are available for all-iron pumps.

SHAFT: Alloy steel, of large diameter to insure power transmission with minimum deflection or vibration. Stainless steel shafts are available as an option.

SHAFT SLEEVE: Renewable bronze shaft sleeve prevents contact between the shaft and the liquid being pumped. Stainless steel shaft sleeves are available as an option.

WEARING RING: Renewable bronze wearing ring pressed into the pump casing is standard on CKB models and optional on CCB and CGB models.

MECHANICAL SHAFT SEALS: Leakless mechanical shaft seals with ceramic and carbon faces, plus stainless steel components eliminate maintenance and adjustment problems. A copper by-pass line (standard on CGB and CKB models, optional on CCB models) prevents dead-ending of abrasives in the seal chamber. Non-standard mechanical shaft seals are available for special operating conditions.

BEARING FRAME: Single piece cast iron construction for maximum strength and rigidity. Bearings are sized and spaced to absorb radial and axial loading. Bearings are greased at the factory prior to shipment, but require periodic greasing in the field.

FLEXIBLE COUPLING: Precision machined with one-piece load cushion to prevent wear on the metal jaws. Couplings are sized for long life under the specified load.

MOTORS: Motors are of NEMA drip-proof design in standard frame sizes. Totally enclosed and explosion proof motors are also available. Motor bearings are factory lubricated and sealed for long life without field lubrication. Fractional H.P. single phase motors have built-in overload protection. All other motors should be provided with magnetic starters.

BASES: Standard units are furnished with formed steel bases. Cast iron drip-rim bases are available as an option.

MODIFICATIONS: Standard pumps are of bronze-fitted construction. Liquid ends can also be furnished in all-bronze and all-iron construction. Pumps can be furnished in close-coupled style, if preferred.

ACCESSORIES: Accessory items are available including coupling guards, vibration eliminator rails, flexible metal hose connections, motor starters, control panels, etc. (NOTE: CCB pump construction may vary slightly from the standard CGB and CKB pump construction described.)
