order to not damage secondary sealings (O´rings
and flat gaskets).
All existing connections, like plugs for external source
liquid, priming, drainage, etc, should be properly covered.
Pump suction and discharge flanges are properly covered
with adhesive, in order to avoid strange contents in its
interior.
Assembled pumps waiting for startup or installation
should have their rotor manually rotated each 15 days. In
case of difficulty, use some adjustable spanner,
protecting the motor shaft surface.
Before conservation liquids application, areas should be
washed with gas or kerosene until they are completely
cleaned.
The conservative liquids can be removed from the areas
in contact with pumped liquid, polished parts and surfaces
like: shaft, salient faces and couplings, by means of
solvents derived from petroleum or clean industrial
liquids. Drain the conservative oil from bearing bracket
before fulfill it with lubricant oil.
3.3 Devolution / discard
3.3.1 Devolution
- Drain the pump correctly.
- Carefully wash and clean the pump, especially in
case of harmful, explosive, hot fluids or other
hazardous fluids.
- In the case fluids are pumped, and they are with
residues which can cause corrosion damage when in
contact with atmospheric humidity or that can ignite
in contact with oxygen, the pump aggregate must be
additionally neutralized and its dry process must be
executed through blowing inert gas without water
through the aggregate.
- Should always be sent with the pump / motor pump
set a certificate of decontamination completely
fulfilled. (Annex 1).
- Please always indicate adopted safety and
decontamination measurements.
3.3.2 Discard
CAUTION
Medium handled is harmful to health.
Hazardous for people and environment!
Collect and dispose of the liquid from
the washing as well as any residual
liquids.
If necessary, use protective clothing and
mask.
Observe the legal disposals related to
the discard of harmful liquids to health.
- Disassemble the pump / moto-pump set.
Collect the masses and lubricants during dismantling.
- Separate materials part of the pump, example:
Metal
Plastic
Eletronic scrap
Masses and lubricants
4. Description of the product and
accessories
4.1 Technical specification
Fields of application:
Used in the chemical and petrochemical industry as well
as in refineries for handling chemically aggressive media
with low solids content.
As well used in industry in general as for process pump
process gas and condensate.
4.2 Designation
KSB WKT 80 / 3
Trade mark
Type series
Discharge nozzle (mm)
Number of stages
For materials refer to the data sheet.
4.3 Design details
Vertical, radially split shaft-driven sump pump with
multiple stages, in wet installation.
4.3.1 Pump casing
Radially split, multiple stages.
For handling combustible media, the pump casing,
the pipe assembly and the flanged elbow must be
made of ductile material with a maximum magnesium
content of 7.5% (see EN 13463-1). This is a standard
feature in all KSB supplies.
4.3.2 Impeller
Closed radial impeller with multiply curved vanes. Axial
thrust is balanced by means of suction and discharge-
side casing wear rings and balancing holes.
4.3.3 Shaft seal
Shaft sealing is effected by gland packing or single or
double acting mechanical seals.
The relevant seal version is shown in the mechanical seal
drawing.
