nance of the pumps.
The user should read this manual before using the pump.
Improper use could damage the pump and cause the forfeiture of the warranty coverage.
When asking our sales and after-sales services for technical information or spare parts, please indicate
the model identification and construction numbers found on the nameplate.
The following instructions and warnings refer to the standard model; for any variations or characteristics
of the special versions please refer to the sales contract.

tact our sales service.
2. Preliminary inspection
Upon delivery check the integrity of the packaging.
After unpacking the pump make sure that no damage has occurred during shipping.
Should the pump be damaged, please inform our agent within 8 days from the delivery date.
3. Applications
The FH series electric pumps are suitable for the pumping of liquids free of aggressive mechanical or
chemical agents in many civil, agricultural and industrial applications. The SH series electric pump can
also handle moderately aggressive liquids.
The SHO and SHOD series of pumps are suitable for pumping liquids containing solid substances mea-
suring up to 60% of the diameter of the discharge port.
4. Working limits
The pump is not suitable for dangerous or flammable liquids.
Maximum working pressure: FH = 12 bar.
SH = 12 bar.
Maximum temperature of pumped liquid: FH = 85°C standard version;
120°C with FPM or Ethylene -
propylene elastomers.
SH = 120°C.
Maximum number of starts per hour: 20 for power up to 5,5 kW
15 for power up to 15 kW
12 for higher power.
Delivery and head must always be within the rated values; any continuous running beyond these values is
anomalous and can damage the pump.
The nominal rotation speed is the one indicated on the pump’s plate.
(1)
Do not refer to the motor plate. Since the motor is suitable for connection with different voltages at 50 and 60
Hz, its plate indicates the number of revolutions for both frequencies.
(1)
This pump, like any other centrifugal pump, can run at a different speed than the rated one if the impeller is replaced. Please contact our sales depart-
ment before carrying out such operations.
5. Installation
5.1 Handling
The product must be handled with care using suitable hoisting equipment; impacts can cause damage
without any visible external signs. Hoist unpacked products securely using a sling.
Do not use the eyebolts on the motor, if fitted, to move the whole pump; only use them to move
just the motor, if it needs replacing, after disconnecting it from the pump.
