HGD Series Parallel Shaft Top Entry Mixers from Cleveland

Drywell Construction
Prevents oil leakage down the impeller shaft

Bearings
All bearings are rated for up to 100,000 hours L-10 life. Timken tapered roller bearings are used throughout the gear box.

Self-aligning shaft coupling
Hollow quill design with optimum bearing span for maximum overload capability.

Splash Lubrication
No pumps to maintain.

Energy-efficient NEMA C-faced motors
Close coupled chemical-duty with 1.15 service factor, and Class B insulation. Motor options include air, DC, severe duty, explosion proof and high efficiency. Available in 3 to 20HP.

Output Speeds
The HGD Series offers AGMA mixer shaft output speeds from 37 to 350 RPM using conventional 1750 and 1170 RPM motor speeds. Competing mixer companies require expensive, single-sourced 850 RPM motors to accomplish the low speed mixing delivered by the HGD.

Impellers
Process related choice of impellers, including one of the highest efficiency hydrofoils on the market. Modified designs of the above are offered along with radial and conventional axial configurations.

Shaft & Impeller Materials
Carbon Steel, 304SS, 316SS
Special alloys, coatings, and polishing available as options

Flanges
8” – 150# standard
6”, 10”, 12”, 14” – 150# available as options

Low Speed Bearing Configuration
High-capacity, spherical-roller, mixer shaft bearing isolates impeller loads from gearing and provides a high moment capacity. Tapered roller bearings accept high thrust loads in either direction.

Re-greasable Low Speed Bearings
Upper tapered roller bearing and bottom spherical roller bearing are grease lubricated and field re-greasable for easy maintenance. Lower tapered roller bearing is flood oil-lubricated. All bearings are rated for up to 100,000 hours L-10 life.

Simple, Positive Lubrication
Sealed, grease-lubricated upper high-speed and intermediate bearing and flood oil-lubricated lower bearings reduce oil levels, churning and foaming for cooler operation. Large oil capacity also helps keep the unit cooler for maximum life. A magnetic oil drain plug is provided.

Easy Maintenance
Easily accessible oil fill opening and oil drain plugs let you perform required maintenance without removing any covers or guards. Standard, automotive-type, quick-check dipstick allows fast, easy oil checks.

Severe-Duty Seals
Shielded, grease-purgeable upper seals provide a grease barrier that traps water, dirt and abrasive contaminants before they can enter the unit and cause damage.

Self Aligning Shaft Coupling
Hollow quill design ensures a solid connection with the mixer shaft and allows for easy installation and positive removal of shafts for various diameters.

No-Leak Drywell Construction
Oil sump is isolated from output shaft to prevent gear lubricants from leaking and contaminating the product being mixed.

Readily Available Replacement Components
Seals, bearings, and high-speed couplings are readily available from the factory. Numbers for these items are published in the HGD service manual.
