Cam-Seal

Certified to meet DOT and UN standards

AMI engineered its Cam-Seal portable agitation unit for speed and simplicity. The result is that its customers can focus on value-added processes, instead of costly housekeeping chores. Workers using Cam-Seal spend the least amount of time sealing portable mixing tanks for shipping and cleaning their wetted surfaces at changeover. The centerpiece of this innovative design is the clever one-piece cam assembly that doubles as a sealing device and a coupling for attaching the shaft to the drive motor. To seal a tank to DOT and UN standards, a worker simply detaches the cam assembly from the drive, pushes the shaft into the tank, and twists it an eighth of a turn so that the assembly's machined in cams engage a set of retaining pins. At cleaning time, a technician disassembles the cam assembly by loosening the set screw and removing the thrust washer and the bolt holding it. The shaft then slides out of the cam assembly. There are no time-consuming, labor-intensive tasks, such as pressing the shaft out of the bearings and fumbling with snap rings. Moreover, the technician cleans only one piece, a smooth, one-piece shaft assembly with no crevices or rough surfaces to entrap material.

AMI's Patented Cam-Seal® *

The fastest mixer to clean and transport.

Four-Dog Coupling
Creates a rigid connection to any mixer drive using this industry standard coupling.

Heavy-Duty Custom Covers
The 10-gauge stainless steel covers withstand the abuse typically encountered in transit and on the plant floor. They are easy to clean and come with any number and types of fittings to satisfy the user's safety and maintenance needs.

Sturdy Shear Guards
Welded shear guards prevent damage to the Cam-Seal assembly and any protruding flanges and venting devices while the sealed tank is in transit or in storage.

Sealing Cam & Locking Pin
To seal a tank for shipping, a worker twists the cam assembly into the retainer pins to tighten the assembly against an o-ring around the opening for the shaft. The spring-loaded locking pin snaps into place automatically to prevent the assembly from working loose.

Paint Slinger
Throws product migrating up the shaft back into the tank to enhance mixing efficiency and to keep the slip fitting in the bearing housing dry and clean. Polished welds and smooth surfaces aid cleaning.

TGP Shaft
Made of 316 stainless steel and custom-cut for the tank’s depth, the 1” turned, ground, and polished shaft is smooth to aid cleaning.

Welded Impeller Blades
Polished welds simplify cleaning by eliminating the innate crevices found at the joint and on the fastener when the blade is attached with a set screw. Four styles of blades and a variety of sizes are available.

Polished Surfaces
An optional electrochemical process can polish all surfaces. The resulting shiny exterior is both smooth and passivated, making it easy to clean and resistant to rust and other forms of chemical attack.

Shipment
Preparing a tank of paint for shipping is a snap with Cam-Seal. A worker simply removes the cam assembly from the mixer drive, inserts the cam assembly into the retaining pins on the tank cover, and twists the assembly an eighth of a turn against the retaining pins until a spring-loaded locking pin snaps into place. The action seals the tank to DOT and UN standards by forcing it against an o-ring around the shaft opening.

When the tank arrives at the user's site, a worker there pulls the spring-loaded locking pin to release the cam assembly, breaks the seal, and lifts the shaft and impeller assembly to meet the drive. Cam-Seal connects to any industry standard four-dog coupling and provides the rigidity for mixing up to 1,000 gallons.

Dual-Use Design
Cam-Seal cam assembly serves two purposes: a coupling to the mixer drive and a sealing device. Dual use means fewer parts, less cost, and a simpler, more reliable mechanism.

A Safe Coupling
The 1/2" ears on AMI's four-dog couplings are extra long to prevent slippage and establish a safer connection.

Sealing Cam
To seal a tank for shipping, a worker twists the cam assembly into the retainer pins to tighten the assembly against an o-ring in the seating flange that contains the opening for the shaft.

Locking Pin
The spring-loaded locking pin snaps into place automatically when the cam is tight enough to seal the tank properly and prevents the cam assembly from working loose. The spring keeps the pin in place until a worker lifts it to break the seal and attach the mixer drive.

Custom O-Ring
Standard version is made of EPDM, but users can specify Teflon or other materials instead. All materials seal to DOT and UN safety standards.

Retainer Pins
Large stainless steel heads hold the cam securely and resist premature wear.

Protective Nylon Sleeve
The replaceable sleeve prevents the shaft and seating flange from wearing and scratching whenever they rub together.

Optional Double Lip Seal
The optional double lip seal can replace the nylon sleeve when sealing the tank or holding pressure is necessary during mixing.

Installation Wrench
Aids workers in pushing and pulling long shafts into and out of large tanks of viscous fluids.
