The drawing here below illustrates the minimum

dimensional requirement of the motor in order to grant

the proper allignment between pump and motor.

Tool AT-190-1 is available upon request to verify

the compliance of the motor to the above mentioned

requirement.

CONNECTING THE PUMP TO THE CIRCUIT

It’s strongly recommendedusing, on the inlet portofthe

pump, pipes and connections of suitable size for the pump

capacity, (8 mm for “CO 30-200” pumps with capacities

upto150l/h,10mmfor“PO70-400”seriespumpswith

capacitiesupto500l/h,15mmfor“PO500-1000”pumps

with capacities up to 1000 l/h.

This precaution avoids the possibility of cavitation and

consequent damage of the pump. The pumps - although

identical in their aspect – may have GAS or NPT threaded

ports. The thread of the fit ting should match the thread of

the pump port. If the pump has GAS threads the sealing

is provided by an o-ring which is pressed against the flat

surface of the port. With the NPT thread, the sealing is

provided by the contact between the threads.

In this case a few turns of PTFE tape around the

fittings are necessary. Do not exceed in using PTFE tape

as pieces of it may fall into the pump (especially on the

Inlet side) and cause the pump to fail. The use of pipe

dope (liquid sealant) should be avoided. A particular care

isneededwhilemountingthefittings,toavoidliquidleaks.

Holdthepumpwithawrenchintheareamarkedwiththe

arrows indicating the inlet-outlet ports and the rotation

sense, without over-tightening. It is recomended not

exceeding 15 Nm torque when tightening the fittings

because the threads on the pump might be damaged.

It is suggested using aluminium sheet on each side of the

pump to avoid damage to the ports. Do not use the motor

as pump support when tightening the fittings, in order to

avoid a possible misalignment and stress of the shafts.

If the pump is made of stainless steel the fittings have to

be made of stainless steel or plastic, not in brass, to avoid

problems of corrosion. The circuit should be carefully

flushed before connecting the pump.

OPERATING CONDITIONS

Make sure that the pumped fluid is compatible with the

materials of the pump. For particular applications, please

contact the nearest authorized Fluid-o-Tech distributor.

• Avoidaswelltouseliquidswithtemperaturehigherthan

70°C(158°F).

• The maximum differential pressure must not exceed

16 bar (230 psi).

• The maximum system pressure must not exceed 20

bar (290 psi).

• Acircuitlayoutwithelbowsandsuddenchangesinthe

diameter of the pipes, causes turbulence in the water

and resonance in the machine.

This is also worsened when the pump is not fed by the

main water line.

• Although Fluid-o-Tech may give technical support,

the final approval of the pumps is responsibility of the

Customer, in fact the performances and reliability may

be affected by particular operating conditions and/or

hydraulic circuit layout.

USEFUL TIPS FOR A LONG LASTING LIFE

OF THE ROTOFLOW PUMPS

The Rotoflow pump is designed to handle clean fluids

only. It is recommended for this reason installing before

the pump a 10 µm filter with a filtering area big enough, so

as not to cause flow-pressure losses in the circuit.

Placethefilteratleast50cmbeforetheinletportofthe

pump in order to avoid cavitation.

It is also important to check periodically the filter

cartridge. In order to keep the filter under control, it is

advisable to install a vacuum gauge before and after the

filter. In case the vacuum increases more than 0,1 bar,

the cartridge should be cleaned or changed.

A dirty filter or an insufficient supply of water causes

cavitation and fast wear of the pump.

The rotary vane pumps are self-priming, but dry running

causes overheating and failure of the mechanical seal and of

theinternalcomponents,andthereforepotentialleaks.

If the line is subject to scarce pressure or flow it is

necessary to fit a low pressure switch before the pump in

order to switch the motor off.

Inorderto avoidcavitation,ifthe tank is at atmospheric

pressure, do not install the pump more than 1 m above

themaximumliquidlevelofthetank.

It is also necessary to protect the system from incidental

overpressures with safety devices such as a pressure relief

valve or a pressure switch connected to the motor.

If possible it’s advisable to install the pump as close as

possibletothetank.

The bypass valve is set from the factory at 12 bar (170 psi)

unless otherwise requested.

The relief valve is not and must not be used as a flow

regulator.

If used as a flow regulator, the water in excess will

recirculate inside the pump through the relief valve

and the pump will fail.

The maximum differential pressure should be at least

2 bar (29 psi) lower than the relief valve setting in order

to avoid operation with the relief valve open.

The maximum differential pressure must not exceed

16 bar (230 psi).

STANDARD MAINTENANCE, SUBSTITUTION

OF PARTS SUBJECT TO WEAR

The rotary vane pumps maintenance, and the

placementofthepartssubjecttowearhastobedone

by Fluid-o-Tech or authorized repair centers. For the

pump with built-in filter it’s recommended the periodic

cleaning of the filter with alcohol and compressed air.

If the filter is external it’s necessary to clean it or to

replace it periodically.

Adirtyfilterdoesn’tallowtheflowoftheliquidthroughit

and causes cavitation and fast wear of the internal parts

of the pump.
