TWIN SCREW PUMPFUKKO's Twin Screw Pump is chosen
for its excellent transfer technology.
Reason for having resistance to high viscosity

Strong suction

T W I NS C R E W

P U M P

Strong suction is created by the high-speed
rotation of the screw.
Complete self-suction method enables theoperation without priming.

Reason for having resistance to contamination

The rotating part iscontactless.
Because of a very little abrasion ofthe screw by the slurry liquid transfer,contamination is not generated.

Mainapplication
areas

Food factory• Ketchup • Liquid eggs
• Rice cakes • Grated radishes• Miso • Whipped cream

1▲SQ-type (Standard type)Best for use withhigh-viscosity slurry
The use of in-tube transfer and non-contact
screws significantly lower running cost compared
to conventional contact-screw-type pumps.

Cosmetics, drug medicines,
and detergents• Shampoo/Hair conditioner • Toothpaste• Liquid detergents • Ointments

Chemical factory• Solvent • Adhesive• Thermosetting resin• Latex

Positive-displacement
self-suction pump with atwin screw.
The liquid inlet to theroom which consists of
two screws and casing ispushed out in the
direction of the thrust
without being kept by
the rotation of the screws.

A little shape breaking allows
smooth transfer.

Reason for having
resistance toeasy to be converted

No stirring

Water Contamination
surfacestillness

High performance

In-tube transfer method allows
continuous transfer rooms topush out materials without
shear force.

Reason for having
resistance towater surface stillness

No pulsation
Continuous transfers by ascrew allow constant discharge
in regardless of viscosity.

Fat factory• Sludge • Waste liquid• Sawdust • Rice straw• UV paint • Slurry ink• Grease • Wax

Because the smaller pumps than ever provide the same
performance as ever, a difference is made on pumpselection.

Making a contribution to the line
simplification and quality assurance

P U M PNo shear

Excellent cost performance

S C R E W

Reason for having
resistance toeasy to be broken

High-speed rotation of 3,600 rpm notshared by conventional pumps
Maximum discharge pressure of
2.0 MPa is achieved.

T W I N

Pushing out liquids in an axial
direction without provision ofturning power allows transfer
of delicate liquids which canbe converted by stirring.

A unit of pump can handle from low viscosity to highviscosity liquids, and the operation efficiency and quality
assurance from liquid transfer to CIP (cleaning in place)are realized.

Structure with consideration ofdisassembling and cleaning

Easy disassembling and quick perfect cleaning are available.

Low noise/vibration

Because the discharge pressure is applied to the thrustload (axial direction), vibration is not generated andoperation is noiseless.

Paper factoryOthers• Cellulose • Woody fiber• Japanese paper material• Emulsion • Pulp material• Carbon • Alumina slurry• Mineral slurry(battery material)

Two series according to applications
Smooth transfer is achieved.
SQ-type

Transfer of any liquid is enabled.

Standard type

Structure with considerationof cleaning• The part that contacts liquids canbe exposed completely forvarious cleaning methods.
• Finish processing withconsideration to cleaning of
inside of the casing• The mechanical seal is removable.

P U M P

• The outside of the casing
optionally can be finished buffing
for the surface to be clean.

Specialized for low moisture content materials difficult to be transferred SQW-type

Twin Screw Pump with Screw Conveyor (PAT)Patented

Mounting a screw conveyor realizes smooth transfer ofsuperhigh viscosity liquids, soft materials like cakes, and others.
Low moisture
contentApplications
Bean curd refuse, corns, etc.

The inlet can be expanded
for smooth input ofmaterials to be transferred.
(Optional)More special applications
can be handled.

The inlet can beexpanded furthermore.

Options are available that are suitablefor your cleaning environment.
Slide bar specification (PAT)The casing can be attached/removed
without touching the screws.

Patented

Slide bar docking system
Operations are easy on a dedicated wagon.

P U M P

Stad specification
Easy disassembling/assembling allows effective
daily cleaning.

A block of materials can be crumbled to be even.

Twin Screw Pump with Paddle
Furthermore with a feeder paddle mounted,
materials like cakes almost solid can be
crumbled to prevent bridges for smooth transfer.
Low moisture
contentApplications
Grease, oil cakes, etc.
