3. General information
3.1. DESCRIPTION
With a compact and robust design, INOXPA’s KSF/KSFT 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).
KSF pumps are designed with a fully health-compliant and easy-to-clean transmission. For KSFT, bolts are fixed through some
countersink. The standard connections are DN 11851. The discharge nozzle is eccentric.
Moreover, there is a more robust design of transmission for a longer service life under heavy duty working conditions.
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 contract with the pumped product are manufactured in AISI 316L stainless steel. The stator is manufactured
in NBR, according to the FDA norm, and the standard sealing is EN 12756 L1K mechanical seal.
This equipment is suitable for his use in food process.
3.2. RANGE OF APPLICATIONS
The curves shown below are valid for both the single- and double-stage stators.
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.).

4.1.1. Identification of the pump
01.30.32.0003
Pump plate
4.2. HANDLING AND STORAGE
KSF / KSFT pumps are often too heavy to be handled and stored manually.
Lift the pump as shown below:
Always use two support points placed as
far apart as possible.
Secure the supports so that they will not
move.

8 4.Installation 2013/10
4.3. LOCATION
Place the pump as close as possible to the suction tank, and if possible below the fluid level.
Place the pump so as to allow around it space enough to access the pump and the motor. (See Chapter 8 Technical
Specification for dimensions and weight).
Mount the pump on a flat, level surface.
The foundation must be rigid, horizontal, level and vibration-proof.
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.
4.4. PIPES
As general rule, fit the suction and discharge pipes in straight sections, with the least possible number of bends and
accessories in order to reduce as much as possible any loss of load caused by friction.
Make sure that the nozzles of the pump are properly aligned to the pipe and their diameter is similar to that of the
pump connections.
Place the pump as close as possible to the suction tank, if possible below the fluid level, or even below the tank, so
that the manometric head of the static suction is highest.
Place pipe supports as close as possible to the suction and discharge nozzles of the pump.
4.4.1. Cut-off valves
The pump can be isolated for maintenance purposes. To such end, cut-off valves must be fitted to the suction and discharge
nozzles of the pump.
These valves must ALWAYS be open during operation of the pump.
4.5. PRESSURISATION TANK
For models with a mechanical seal, a pressurisation tank needs to be fitted.
1...2m
Cierre mecánico
Figure 4.6: Pressurisation tank installation sketch
For more information on the pressurisation tank (installation, operation, maintenance, etc.), see the manufacturer’s instructions
manual.
ALWAYS install a pressurisation tank 1 to 2 meters above the pump shaft. See Figure 4.6.
ALWAYS connect the cooling fluid inlet to the lower connection of the seal chamber. Therefore, the
outflow of the cooling liquid will be through the upper connection of the chamber. See Figure 4.6.

2013/10 4.Installation 9
4.6. ELECTRIC WIRING
The connection of the electrical motors must be performed by a qualified operative.
Take all necessary precautions to prevent the failure of connections and cables.
The electrical equipment, the terminals and the components of the control systems may still bear
electrical current when powered off. Contact with them may be dangerous for operators or cause
irreversible damage to equipment.
Before handling the pump, Make sure that the motor is fully disconnected from the power.
Connect the motor following the manufacturer’s instructions.
Check the direction of rotation (see the label on the pump).
Start the pump motor briefly. Make sure the pumping direction is the right one. If the pump operates in the wrong
direction it may cause severe damage.
ALWAYS check the direction of rotation of motor with fluid inside de pump.
For models with a seal chamber, ALWAYS make sure that the chamber is full of fluid before checking
the direction of rotation.

10 5.Start-up 2013/10
5. Start-up
Before starting the pump, carefully read the instructions given in Chapter 4. Installation .
5.1. START-UP
Read Chapter 8 Technical Specification carefully. INOXPA cannot be held responsible for the improper
use of the equipment.
NEVER touch the pump or the pipes when hot fluid is being pumped.
5.1.1. Checks before starting up the pump
Fully open the cut-off valves on the suction and discharge pipes.
If the fluid does not flow into the pump, fill the pump with fluid.
The pump must NEVER rotate without fluid inside it.
Check that the power supply matches the rating indicated on the motor plate.
Check that the direction of rotation of motor is the right one.
If the pump has a double or a cooled mechanical seal, mount the auxiliary connection corresponding to the values
indicated in Chapter 8, Technical Specification .
5.1.2. Checks when starting up the pump
Check whether the pump makes strange sounds.
Check whether the absolute inlet pressure is enough to avoid cavitation in the pump. See the curve to determine the
minimum pressure required above steam pressure (NPSHr).
Control discharge pressure.
Check that there are no leaks through the sealed areas.
A cut-off valve on the suction pipe must no be used to regulate flow. Cut-off valves must be fully
open during operation.
Control motor consumption to avoid power overload.
Reduce flow and motor power consumption by reducing motor speed.
5.2. BY-PASS PRESSURE
If the pump has an incorporated pressure by-pass, the rotation can be of only one direction. To invert the direction of rotation,
mount an overflow valve as indicated the next figure. The single stage pump has the overflow valve calibrated at 6 bar and at
10 bar for the double stage ones. In both cases this is the maximum pressure.
The pump always leaves INOXPA with by-pass mounted to work with the aspiration in the pump
casing and the impulsion ahead.

(57) manually and evenly, and make sure that the shaft rotates freely. Now follow the assembly procedure described in section
7.4.1.
Let the pump operate with constant leaks for about 10 minutes, then fasten the gland (37) using the nuts (57) until the leaks
are reduced to an acceptable level (15 to 20 drops/minute). A dripping leak is essential for the normal operation of the gland
packing in order to avoid the overheating of the screws.
When the packing has become fully compressed after successive adjustments, replace the full contents of the box (never
replace the packing only partially). Always use good-quality packing.
7.4.6. Change of drive
Disassembly
Remove the elastic pin (05) from the shaft complement (26).
Remove the screws (52A) and the washers (93) and pull out the drive (93).
Assembly
Drill a hole in the drive shaft as shown in the figure below. Mount the drive (93) to the flange support (06A) and fasten it with
the screws (52A) and washers (53A). Slide the shaft complement (26) over the drive shaft (93) and fasten it with the pin (56).
