■ 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
