CHANNEL, VORTEX AND SPIRAL VANE CENTRIFUGAL
PUMPS: PROMIX
CHANNEL PUMPS
RCN/RCPN SERIES
Horizontal single stage centrifugal pumps with overhung
impeller and axial suction, constructed using the "Back
pull-out system" and available with four different sizes of
support.
Main technical features
- Flow rate up to 800 m3/h
- Discharge head up to 75 m
- Working pressure up to 10 bar
- Working temperature from -30 to +170°C
- Size from 65 to 200 mm
- Flanges drilling UNI PN10
Advantages
- The channel impeller with wide inter-vane passages makes it
possible to convey, without any danger of blockages, liquids containing
particles in suspension, without fibrous materials, chemically
inert or aggressive.
- Maximum efficiency
- Reliability
- Compactness
Fields of application
- The paper and chemical wood pulp industries
- The sugar industry
- The farm-food industry
- Waste water and sewage treatment plants
- The chemical and petrochemical industry
- The iron and steel industry
- The mining industry
- The construction sector
Materials
The RCN-RCPN pumps can be made both of cast iron or AISI 304 or
AISI 316 L stainless steel.
Shaft seal
The RCN-RCPN pumps can be equipped with various types of seal:
- Soft packing with liquid barriage
- Mechanical seals (simple, balanced, double,
cartridge, with quench ...,) with standard circulation and flushing
in accordance with the API Standard 610 norms.
- Hydrodynamic seal: this is an innovative seal
comprising a secondary impeller installed behind the main impeller
which makes it possible to operate with particularly abrasive
liquids or with solutions that easily deposit the solute.
Special productions
On request the pumps can be supplied:
- With cooled sealing chamber
- In vertical submerged version
VORTEX PUMPS
RKC/RKN SERIES
Horizontal single stage centrifugal pumps with over hung impeller
and axial suction, constructed using the "Back pull-out system"
and available with four different sizes of support for the RKC series
and a single size for the RKN series.
The pumps function by making use of the induced vortex principle:
the impeller, which is positioned further back than the pump body,
because of its particular shape induces a vortex in the conveyed
liquid which expands in the body creating the pump discharge head.
Main technical features
- Flow rate up to 700 m3/h
- Discharge head up to 70 m
- Working pressure up to 10 bar
- Working temperature from -50 to + 170°C
- Environmental temperature up to 40°C
- Size from 65 to 200 mm
- Flanges drilling:
- UNI PN10 for RKC series
- UNI PN16 for RKN series
Advantages
- The open impeller, which is positioned further back, with wide
inter-vane passages makes it possible to convey, without any danger
of blockages, dirty or viscous liquids, liquids containing particles
in suspension or with fibrous impurities, chemically inert or
aggressive liquids and those with dissolved air and solutions
with crystals in suspension
- High performance levels
- Reliability
- Compactness
Fields of application
Because of their operating characteristics , the RKN and RKC pumps
are particularly suited for use in the following plants:
- The paper and chemical wood pulp industries
- The sugar industry
- The farm-food industry
- The textile industry
- Waste water and sewage treatment plants
- The construction sector
- The chemical and petrochemical industry
- The pharmaceutical industry
- Thermo-electric power stations
Materials
The RKN pumps are made of AISI 316 L stainless steel. The RKC pumps,
on the other hand, can be made of AISI 304 or AISI 316 L stainless
steel, or cast iron.
On request it is possible to supply products made of special nickel
based alloys to resist against the chemically more aggressive components
such as sulphuric acid or hydrochloric acid.
Shaft seal
The RKN pumps are equipped with soft packing seals but, depending
on the liquid conveyed, simple, double, or in tandem mechanical
seals can be installed with standard circulation and flushing in
accordance with the API Standard 610 norms.
Special productions
On request the pumps can be supplied:
- With cooled sealed chamber
- In vertical submerged version
SPIRAL VANE PUMPS
RACN SERIES
Horizontal single stage centrifugal pumps with overhung impeller
and axial suction, constructed using the "Back pull-out system"
and available with five different sizes of support.
Main technical features
- Flow rate up to 1400 m3/h
- Discharge head up to 80 m
- Working pressure up to 10 bar
- Working temperature from -30 to +170°C
- Size from 80 to 300 mm
- Flanges drilling UNI PN10
Advantages
- The semi-open impeller, which is positioned further back, with
wide inter-vane passages makes it possible to convey, without
any danger of blockages, dense and/or highly viscous liquids with
solid particles in suspension, solutions with high percentages
or dry matter, and chemically inert or aggressive liquids.
- Very high suction capacity
- Extremely low NPSH values
- Particularly advantageous from the economic point of
view for plants with low NPSH values
Fields of application
- The paper industry, conveying of paper pulp up to concentrations
of 15% dry residue
- The chemical wood pulp industry, conveying of cellulose and
wood pulp
- The farm-food industry
- The sugar industry
- The chemical industry
Materials
The RACN pumps can be made both of cast iron or AISI 304 or AISI
316 L stainless steel.
Shaft seal
The RACN pumps can be equipped with various types of seal:
- Soft packing with liquid barrage
- Mechanical seals (simple, balanced, double, cartridge, with
quench ...,) with standard circulation and flushing in accordance
with the API Standard 610 norms.
- Hydrodynamic seal: this is an innovative seal comprising a
