LANDY SCREW PUMPS BECAUSE...
In addition to the general characteristics andadvantages of screw pumps, the Landy screwpumps are distinguished by:
A first class product with
screw pump technology
Nearly 100 years experience
Efficient design - - usually 2 flights- Limited deflection- Limited occuring tension- High efficiency- Alternate flight pitchOngoing R&DFinite Element Analysis standardon all new designs.Full in-house integrated manufacturing
Totally reliable manufacturing schedules
and delivery times
Endplates- Fully watertight with internal caps
over threads of connection bolts- Precisely parallel and centric manufacture
using special lathes- Special ST-44 material
Reinforced leading edges of flights
Manufactured with permanent lifting eyesand balancing weights
Fully qualified welders- X-ray or ultrasonic- Welding Shop Approval- AWS/DIN standards
Surface Preparation. Shot blasting toSP-10 standards.
Coating. All required coatings areprofessionally applied, and can beformulated for extreme environments.- Please contact us for severe abrasion,
chloride, pH or H2S applications.
Stainless Steel Screw Pumps available.
Flanged shafts are monolithically castnodular cast iron.
Use of fully self-aligning bearings
World-wide service with local support
Superb after-sales service
We can offer full supervision of
installation.
STATE-OF-THE-ART
Completely enclosed unit
LOWER BEARINGS
Landustrie Screw Pumps are available with fourdifferent Lower Bearing designs. The newest andmost exciting of which is the permanentlylubricated, completely self-contained, and fullyself-aligning in all 3 axes, Landy Eco-Friendlysystem as detailed below.
All our Lower Bearing types carry the radial thrustforces while also accommodating longitudinalexpansion and contraction brought about bytemperature changes. The special merits of all fourLandustrie Lower Bearing designs are convenientlyoutlined in the Table on the opposite page.
No maintenance and no grease costs

UPPER BEARINGS
For the upper bearing EPIC can offer the choicebetween two different versions; a wall-mountedor a foot-mounted upper bearing. The benefits ofthe wall-mounted upper bearing are that theforces on the civil construction will be betterabsorbed, and also that an odor-tight separationis created between the screw pump and theroom in which the drive-unit is installed.

RESEARCH AND DEVELOPMENT
For many generations Landustrie has been actively conductingresearch to continuously improve Screw Pump performance,efficiency and longevity.
The newest development in the most recent 10 years of our testingprogram is the permanently lubricated, fully 3-dimensionally self-aligning, and completely self-contained Eco-Friendly LowerBearing. In addition, Landustrie now conducts Finite ElementAnalysis on all our new Screw Pump designs.
