⑬ Screw Pump

■ Non-clog pump for unscreened sewage and sludges.


♧ Usages and applications
For the applications and services such as unscreened
sewages, sludges, waste water, raw water, food-stuffs waste,
paper pulp, slurry, gas-entrained liquid, fibrous liquid,
fish, etc, transfer and feed in the waste treatment plant
and various branches of industry.


♧ Design and operation features
01.By combining design theories of volumetric screw pumps
and centrifugal pumps, improved the design of
conventional non-clog pumps.

02. Steep curve of performance enables easy control of capacity.
03. Power consumption is not so much sensitive to the
variation of flow.

04. Suitable for pumping of liquids with high viscosity
or containing solids.

05. Clearance between the impeller
and the suction cover is adjustable.

06. Impeller back pull-out design.
07. Counter Clock wise(CW) rotation
when viewed form the driver end.

08. Uncooled stuffing box. Packing rings or mechanical seal.
09. Roller bearing and ball bearing. Oil bath type lubrication.
10. Welded steel base plate, machined both up side and bottom side.
11. Flange : KS D 4308

* The out of the above range can be supplied
according to customer’s order placement.


♧ Operating data
Capacity : 0.05m³/min ~ 35m³/min
Head : 3m ~ 92m
Suction Bore : Ø80mm ~ Ø600mm

♧ Use and applications
01. Sewage treatment, Chemical, Ceramic, Construction,
and Hining industry

02. Food, Beverage, Sugar and Starch industry,
Pharmaceutical industry.


♧ Principle
Eccentric Screw pump consists of a single helix metal rotor
which rotates eccentrically within an elastomeric stator
with a double helix form. The interference fit between the rotor
and stator creates a constant cavity which carries the pumped product
continuously through the pump.


♧ Design and operation features
01. Eccentric Screw Pump conveys easily high viscous
and high dense material.
02. Uniform, Non-pulsating flow.
03. High suction capability.
04. Vulcanized-in, Easily replaceable stator,
Torsion-proof, therefore a Long service life.


♧ Operating data
Capacity : 1m³/Hr ~ 75m³/Hr
Head : 1Kg/㎠ ~ 5Kg/㎠
Suction Bore : Ø40mm ~ Ø125mm
