G series Mono Screw Pump Progressive Cavity Pump for slurry and oil
The G-type single-screw pump is a new type of pump that works on
the principle of squeezing meshing volume. The main working
components are the eccentric screw (rotor) and the fixed bushing
(stator). Due to the special geometrical beginning of the part, a
separate sealed cavity is formed. The medium is uniformly propelled
by the axial flow. The internal flow rate is low and the volume
remains the same. The pressure is stable and therefore does not
vortex and agitate the product. Single-screw pump is widely used in
various industries to transport all kinds of media, constant
pressure continuous operation, no pulsation, no damage to the
medium transportation, and the flow rate is changed by adjusting
the rotation speed to achieve the purpose of measurement. This
product is suitable for conveying media with high solid content (up
to 150mm maximum particle size) or no solid content | various
viscosities (1mPas - 3m mPas) | Thixotropic and extensible media |
Sensitive medium|Abrasive medium|Medium/non-lubricating
medium|Corrosive medium (pH=O-14)|Cohesive medium|Toxic medium|High
flow rate, high pressure·Flow range from a few milliliters per hour
Up to 500m3 (2200gpm) · Pressure range up to 48bar, special design
up to 72bar. The same drive unit can be matched to the rotor/stator
of four different designs to give you the best possible solution.
G-type single-screw pumps are available in different applications
for different applications, from cast iron and nickel-chromium
steels to acid-resistant materials, Hastelloys and titanium alloys.
Elastic materials can be selected from wear-resistant,
oil-resistant, acid-resistant, alkali-resistant rubber, such as
natural rubber, nitrile rubber, ethylene propylene rubber and
fluoro rubber. For abrasive media, ceramic or plastic is available.
When the medium is not suitable for elastic materials due to high
temperature or containing certain chemical components, a hard
material stator or a rigid stator may be used. Various shaft seal
forms: According to the customer's requirements, the mechanical
seal is sealed from a single-end machine (with or without
smelting), double-faced machine seals (back-to-back and tandem
mechanical seals) to a box seal; , water seal ring and special
seal. A leak-free magnetic drive is available for toxic media.
Application:
1. Environmental protection: the transportation of industrial
sewage, domestic sewage, muddy water containing solid particles and
short fibers. Especially suitable for oil water separators, plate
and frame filter presses and other equipment.
2. Shipbuilding industry: transportation of media such as wheel
bottom cleaning, oil water, oil slag, oil sewage, etc.
3. Petroleum industry: transporting crude oil. In recent years, it
has been particularly successful in pumping a mixture of crude oil
and water deep underground, a mixture of coal gas and water in the
coal field, thereby greatly reducing the cost of mechanical oil
recovery and coal mining. When the oil field is late, the use of a
screw pump to inject polymer into the formation increases oil
recovery.
4, medicine, daily: a variety of sticky pulp, emulsion, various
ointment cosmetics and other transport.
5, food canning industry: a variety of viscous starch, cooking oil,
bee secret, sugar sauce, fruit pulp, butter, fish oysters and the
delivery of their scraps.
6, brewing industry: a variety of fermented viscous liquid, strong
wine trough, grain products, various sauces, pulp and mucus
containing solids.
7. Construction industry: spraying and conveying of cement mortar,
lime slurry, paint and its paste.
8. Mining industry: underground and slurry water containing solid
particles in the mine are discharged to the ground.
9. Chemical industry: various suspensions, greases, various
colloidal pulps, various adhesives.
10, printing, paper industry: high-viscosity ink, wallpaper PVC
polymer paste and various concentrations of pulp, short fiber
slurry transport.
