Delroyd’s New
Delivery Commitment
from Order-to-Delivery
in 3 Weeks!
P30 - P40 - P50 - P60 &
HP40 - HP50 - HP60 Units
This NEW delivery commitment is a result of:
• Capital Investment in New Machinery
• Improved Manufacturing Processes
Fluid mixing is often a very complex process. While the
properties of the materials to be mixed, as well as the
mixing vessel and agitator are very important considerations,
the type of drive can greatly affect mixing costs - both
operating and initial investment. For a wide variety of
materials in chemical, process, pollution control and many
other applications, Delroyd worm gear drives for mixers and
agitators offer many advantages over the other types of
gearing and drive units.

Worm Gear Mixer Drives Features
• Delroyd Unique Worm & Gear Design
- Operation with multiple tooth contact
- Shockless power delivery
- Quiet operation (meets OHSA sound standards 76 to 80 Dba)
- Provides economical & efcient at low speeds
• Available Single reductions from 5:1 through 70:1 for output
speeds down to 25 rpm (standard 1750 rpm motors)
• Available Double reductions from 15:1 to 350:1 to provide outputs
as low as 5 rpm
• Note: Gearing efciency is quite different from mixing efciency.
Mixing efciency is inuenced by gearing efciency
• Delroyd worm gear drives are engineered to withstand up to
300% momentary peak overloads and shock loads
• Delroyd mixer drives offer a minimum service factor of 1.25
• In Delroyd units, heavy-duty tapered roller bearings (B-I0 life
of over 10,000 hours on the worm shaft; B-I0 life of 100,000
hours on low speed shaft) minimize shaft vibration and sensitivity
to shaft deection. This eliminates the need for hollow quill
construction and lowers the overall cost of the mixer/agitator.
• The centrifugally cast phosphorous bronze gear mates with a
hardened, ground and polished steel worm. As the drive operates,
the bronze gear conforms and work-hardens to the contour of the
worm. This is responsible for the saying that “Delroyd worm gears
wear in, not wear out.”
• Standard drywell construction provides positive protection against
leakage of lubricants. There’s no danger of product contamination.
• Standard Delroyd units range from 3 through 14-inch center
distances, and horsepower from .132 to 265 HP.
• Drives with even larger center distances and greater horsepower
are available.
