4.General Information
4.1. DESCRIPTION
With a compact and robust design, INOXPA’s KIBER KS and KST progressive cavity pumps form part of our
range of positive-displacement pumps with helical rotor, intended for viscous fluids.
The hydraulic parts that form the pump are the rotor and the stator. The rotor is a round-section worm. The
stator has two ribs and its pitch doubles that of the rotor, thus allowing empty cavities between the stator and
the rotor. These cavities are used to transport the fluid. When the rotor turns within the stator, the cavities move
longitudinally from the suction area to the discharge nozzle.
These kinds of pumps are suitable for pressures from 6 bar (single-stage stator) to 12 bar (double-stage stator).
KS pumps are designed with a fully health-compliant and easy-to-clean transmission. For KST, bolts are fixed
through some countersunk screws. The discharge nozzle is eccentric.
Moreover, there is a more robust design of transmission for a longer service life under heavy duty working
conditions.
The standard connections are DIN 11851. Also, it is possible to choose other types of connections for the pump,
like the CLAMP, SMS, RJT, flanges DIN 2633 PN 16, etc.
All pump parts in contact with the pumped product are manufactured in 1.4404 (AISI 316L) stainless steel,
except the feeder screw of the KIBER KST pump which is manufactured in 1.4301. According to the FDA norm,
the stator is manufactured in NBR and the standard sealing is EN 12756 L1K mechanical seal.
This equipment is suitable for his use in food process.
4.2. APPLICATION
The KIBER KS and KIBER KST progressive cavity pumps are used to transfer products of low and high
viscosity as well as products containing soft particles.
Some of its applications are for use with edible oils, wine, concentrates and beverages in general.
The intended use of the pump is defined for its characteristic curve.
The range of application for each type of pump is limited. The pump was selected for a given set of
pumping conditions when the order was placed. INOXPA shall not be liable for any damage
resulting from the incompleteness of the information provided by the purchaser (nature of the fluid,
rpm, etc.).

Lift the pump as indicated below:
•always use two support points placed as far apart as possible.
•secure the supports so that they will not move.
See chapter 9. Technical Specifications to consult dimensions and weights.
During the transport, disassembly or assembly of the pump, there is a risk of loss of stability and
that the pump could fall down and cause damages to the operators. Make sure that the pump is
properly supported.
5.4. LOCATION
•Place the pump as close as possible to the suction tank and it is possible below the level of the liquid.
•Leave sufficient space around the pump to provide access to both pump and motor. See chapter 9.
Technical Specifications to consult dimensions and weight.
•Place the pump on a flat and level surface.
•The foundation must be hard, level, flat and vibration free.
Install the pump so as to allow proper ventilation.
If the pump is installed outdoors, it should be covered by a roof. Its location should allow easy
access for inspection or maintenance operations.
If the hopper is not covered when the KST pump is installed at the process, the hopper must cover
in order to avoid the accidental access the operators to the pump’s moving parts.
5.4.1. Excessive temperatures
Depending on the fluid to be pumped, high temperatures can be reached inside and around the pump.
Over 68ºC the operator should take protective measures and place warning notices advising of the
danger which exists if the pump is touched.
The type of protection selected should not isolate the pump entirely. It should allow for the bearings
to be cooled more efficiently and for the bearings to be lubricated.
5.5. COUPLING
For the selection and fitting of the couplings, please refer to the supplier’s manual. In some cases, the starting
torque of positive-displacement pumps can be quite high. Therefore, the chosen coupling should be 1,5 to 2
times the recommended torque.

The coupling has to be adequately protected during operating the pump to avoid possible accidental accesses.
Do not operate the pump if the protectors are not installed adequately.
5.6. PIPES
•As a general rule, install the suction and discharge lines in straight sections, with the minimum possible
number of elbows and fittings in order to reduce any pressure losses that may be caused by friction.
•Make sure that the pump’s ports are properly aligned with the pipework and have a diameter similar to that
of the pump connections.
•Place the pump as close as possible to the suction tank and whenever possible below the liquid level, or
even below the tank level in order to achieve the largest possible static head for suction.

•Install support brackets for the lines as close as possible to the pump’s suction and discharge ports in order
to avoid vibrations and stress on the pump.
5.6.1. Shut-off valves
The pump may be isolated for maintenance. To accomplish this, shut-off valves must be installed and
connected to the pump’s suction and discharge connections.
These valves must ALWAYS be open during operation of the pump.
5.6.2. Pressurisation tank
For models with a double mechanical seal, a pressurisation tank needs to be fitted.
ALWAYS install the pressurization tank at a height of between 1 and 2 meters with respect to the
pump shaft.
