B. Introduction
1. Introduction
1.1 The instruction manual contains important information on how to operate the pump safely,
properly and most efficiently. Observing these instructions helps to avoid danger, to reduce
repair costs, downtimes and to increase the reliability and life of pump.
1.2 The operating instructions must always be available wherever the pump is in use.
1.3 The operating instructions must be read and applied by any person in charge of carrying out
work on the pump.
1.4 Observe the mandatory rules and regulations for accident prevention and environmental
protection in the country and place of use of the pump. The generally recognized technical
rules for safe and proper working must also be observed.
1.5 It is presumed that fundamental project work as well as all work with regard to transport,
assembly, installation, start-up, maintenance and repair is performed by qualified personnel
or supervised by skilled labor taking overall responsibility.
2. Safety
2.1 A pump that is installed incorrectly, operated wrongly, or maintained poorly can present a
hazard. If the following considerations are overlooked, the safety of personnel or satisfactory
operation of the pump may be endangered.
2.2 Attention must be given to the safe handling of all items. Where pumps, pump units or
components weigh in excess of 20 kg (44 lb.), it is recommended that suitable lifting equipment
should be used in the correct manner to ensure that personal injury or damage to pump
components does not occur.
WARNING Note that lifting eyes fitted to individual pieces such as pump and motor are designed to lift
only this part and not the complete assembly.
2.3 Before starting to dismantle a pump all relevant and appropriate safety precautions must be
taken, particularly if the pumps have been handling hazardous or toxic products. Seek advice
from your safety officer or the manufacturer if you have any doubts.
2.4 Always wear adequate protective clothing and eye protection when dismantling pumps that
have been used to pump toxic or hazardous products. Breathing apparatus may be necessary.
2.5 Always isolate the pump electrically before dismantling. Ensure that the electrical switch gear
cannot be operated whilst any work is being carried out on the pump.
2.6 Always drain the pump casing of product before removing the pump from its associated pipe-
work.
2.7 Flush out the pump casing and shroud with a compatible flush and drain away to a safe area.
2.8 Check with your process people to see if any special decontamination procedures have to be
followed before working on a pump.
2.9 All pumps returned for factory servicing must be decontaminated and labeled to inform what
precautions should be taken before dismantling.
3. Shipment inspection
3.1 Pumps and units are shipped suitably protected to prevent damage in transit from normal
handling. When received, the shipment should be inspected immediately. Damages to the
packaging or crating that may reveal content damages when unpacked should be reported to
the carrier and possibly photographed.
3.2 A photograph is helpful in any claims to be made against the carrier. Inform manufacturer or
the local authorized distributor, too.

3.3 Shipment shortages, checked against the transport documents, should be reported to the
carrier.
3.4 Check the nameplate data against the shipping papers and against your purchase order to
ensure that the proper pump is provided.
4. Storage
4.1 After receipt and inspection, a pump not immediately installed should be repackaged and
placed in suitable storage.
4.2 Protective coatings on unpainted surfaces should be inspected and left intact. Unpainted
surfaces, not factory treated with a rust inhibiting coating, should have a protective coating
applied.
4.3 Plastic or gasket type port covers should be left in place.
4.4 Pumps should be stored in a clean, dry location. When moist, dusty atmosphere must be used
for storage, further protect the pump with a moisture repellent cover.
4.5 If the pump has been used please empty the pump casing by opening the clean-out cover or
plug and fill with some corrosion inhibiting oil.
WARNING Never forget water inside pump casing during cold weather! Water may freeze and break the
pump casing!

C. Operation
1. Installation
1.1 Set up the pump on a flat surface as near as possible to the liquid to be pumped. Make sure
that the surrounding is adequately ventilated.
1.2 Suction hose or pipe should be as short as possible and should have the same diameter as
the pump port. It is recommended minimize the use of curves, corners or necks. This will
reduce the priming time and ensure full capacity.
1.3 Check that any connections (threads, welds, gaskets, quick-couplings, valves, etc.) are
completely airtight: if necessary, coat them with grease.
1.4 It is advisable to use a suction filter to avoid to suction solids larger than those that pump can
accept. The value of the maximum pump solids is indicated in the attached curve.
1.5 In the event that a pump without a non-return valve stops working, the liquid could flow back.
To avoid this, fit a non-return valve on the delivery or suction side.
1.6 Connect the electric motor with authorized personal only (see section E “Electric Motor”, on
page 8).
2. First Start-up
2.1 Use the pump only in the authorized performances levels indicated in performance curve,
technical datasheet and instructions! The liquid should never be pumped on the limit of
vaporization, crystallization, polymerization or solidification.
2.2 The material of the pump must be compatible with the pumped liquid. The pump manufacturer
has no responsibility on this.
2.3 To self-prime the first time, the pump must be under water head. This means that the liquid
has already entered into the pump casing before the first start-up.
2.4 Check that direction of rotation is the same as shown by the arrow on the back of the pump
(clockwise when looking from the shaft or motor end, for the C 30 counterclockwise).
2.5 Open all valves. Otherwise the mechanical seal can be damaged.
2.6 Start the pump and check after some minutes if the pump is working as planned. The time to
reach the optimal operation should not exceed 2 min.
WARNING Any deviation from normal operating conditions (increased power consumption, temperature,
vibrations, noise etc.) or warning signals by monitoring equipment suggest malfunction. Inform
the responsible maintenance personnel at once to prevent the trouble from getting worse and
causing, directly or indirectly, serious physical injury or material damage.
In case of doubt disconnect the machine immediately!
3. Running
3.1 Start and stop the pump if necessary. The pump is designed for 6 starts per hour. More
frequent start cycles must be approved by the pump producer.
3.2 If the suction line is empty, it is necessary to fill it before to start the pump. The pump cannot
pump air.
4. Operating troubles
4.1 PUMP DOES NOT PRIME (pumps does not pump the liquid)
(a)Air leaks into the suction line (through couplings, threads, flanges, gaskets, hose clips, cuts,
etc.). It is difficult tofind thetrouble place.
(b)Level of liquid inside pump casing is too low or empty. Pump must be always full of liquid,
better if it is placed under water head.

(c) Wrong direction of rotation or too low speed.
(d)Overpressure in the delivery line.
(e)Overheated liquid that vaporizes. This stops pumping. Wait until the liquid cools down or
replace it with a cold liquid, then restart the pump.
(f) Air leaks through the seal because of damaged seal. Replace it.
(g)Volute worn out by abrasive liquids.
(h)Clogged, broken or worn impeller.
4.2 LOW CAPACITY
(a)Strainer or filter clogged. Clean out.
(b)Suction or delivery lines clogged. Locate and remove obstruction.
(c) High friction losses in the line. Get rid of unnecessary curves, valves and constrictions.
(d)Static suction lift too high. Place the pump as close as possible to the surface of liquid to
be pumped.
(e)Low rotation speed. Increase RPM.
(f) Impeller clogged. Free impeller through the inspection cover or open the pump casing.
(g)Impeller and/or wear plate(s) worn out. Replace.
4.3 PUMP IS MAKING NOISE
(a)Discharge side or suction side closed or clogged. Install a manometer in the discharge side
and a vacuum meter in the suction side to inspect the piping.
(b)Impeller clogged. Free impeller through the inspection cover or open the pump casing.
(c) Cavitation. The pump is working outside the allowable curve. Check how the sound
changes by slowly closing and opening the valve in the discharge side.
(d)Ball bearing worn out; replace.
4.4 PUMP IS LEAKING
(a)Loosen screws. Check.
(b)Loads on the pump and piping to high. Check.
(c) Overpressure. Mechanical seal or gaskets damaged.
(d)Dry-running or closed lines. Mechanical seal overheated and broken. Replace.
(e)Rubber components not compatible with the pumped liquid. Please contact your pump
partner for alternatives materials.
4.5 For any other operation troubles, please contact your pump partner by mentioning:
⇒Pump type
⇒Serial no.
⇒Problem
⇒Running time
⇒And possibly attach photographs.
5. Maintenance
5.1 After start-up the pump will need to be checked at the following intervals to make sure it is
pumping properly and with regard to pump noise: 10 min. / 1 hour / 1 day / 1 week / 1 month.
Inspection may take place thereafter at monthly intervals provided the conditions of use do not
change.
WARNING When pump is not used, never forget water inside the pump casing during cold weather! Water
may freeze and break the pump casing!

5.2 Each 6 months open the inspection cover or the casing and check inside. Remove possible
foreign parts. Clean the pump and the motor. If necessary, check more frequently.
5.3 Each 5-10 years make a general pump recondition.
6. Lubrication of the mechanical seal
6.1 Pumps with carbon graphite mechanical seal (i.e. .06. / .30. / .302. / .35. / .10. / .16. / .55.)
have no lubrication and do not need any maintenance.
6.2 Models with mechanical seal with diamond coating (.36., .362.) have no lubrication and
therefore need no maintenance.
6.3 Models with grease nipple do not need any maintenance for the first 200 working hours. After
this period lubricate each 3 months with only one hub of grease. Use standard grease with
viscosity grade between 1 and 3. With alkaline products (ex. lime-milk) use the special grease
(please contact your pump partner).
WARNING Do not over-grease, otherwise the narrow ball bearing can be damaged!
7. Warranty
7.1 The manufacturer warrants the pump against defects or faulty workmanship for a period of 12
months from the date of delivery. Longer warranty periods are available on request.
7.2 Repair of the pump or replacement of parts or of the pump itself can only be carried out after
careful examination of the pump in our workshop where the pump should be sent by carriage
paid. Any exceptions must be confirmed in writing.
7.3 Warranty does not cover parts damaged by improper operation, handling and assembly, as
well as parts subjected to deterioration and normal wear (especially impellers, wear plates and
mechanical seals).
7.4 Warranty is no longer valid if the pump is disassembled or modified without the authorization
of the manufacturer.
WARNING Never forget water inside pump casing during cold weather! Water may freeze and break the
pump casing!
