Manufacturing

FICEM POC series rotary electric pumps are single stage pumps with “in-line” intake and delivery openings of equal diameter, with coupling to the electric motor by means of flexible coupling, all supported by a robust base equipped with suitable accident prevention protection. The electric pumps are equipped with a three-phase and/or single-phase asynchronous electric motor, with external fan cooling, IP55 rating, class F insulation, 2RS oversized, self-lubricating ball bearings.

The pump shaft is connected to the motor directly, without joints, reducing vibration to a minimum. The whole range is available with pipe thread connections for quick coupling to the system piping, preventing any dripping or leaking of liquids.

The electric pumps use an unbalanced mechanical seal, supplied by a leading Italian manufacturer.

Mechanical Seal

Two types of unbalanced mechanical seal are available:

Type 3
The type 3 mechanical seal is an inexpensive, highperforming seal, with interchangeable components.
The standard Ceramic/Carbon pairing gives this type of mechanical seal a wide variety of uses, even with impure liquids.
The possibility to replace the wear rings minimises maintenance costs.
The metal components are made of stainless steel.

Type 5
The main characteristic of this mechanical seal is the ability to mount any type of elastomer. Furthermore, it is particularly suitable for heavy-duty uses such as the offsetting or misalignment of the structure in which it is used.

Specific mechanical seals are available for liquids containing suspended abrasive particles.

Connections

The whole range of FICEM POC series electric pumps is available with pipe thread connections. Horizontal operation of the electric pump is envisaged.

Adjustment

In order to adjust performance on the basis of requirements, it is possible to use POC series electric pumps, connecting them to control systems which provide continuous performance adjustments based on needs. Furthermore, these electric pumps are equipped with a BY-PASS, which allows the setting of the MAX value of the total head.

Product features and advantages

Optimised hydraulics
The geometry of the impellers and the pump bodies guarantees high levels of efficiency and reduced energy
consumption.

Highly efficient motors
The whole electric pumps production range uses excellent quality electric motors with the EFF2 class of efficiency.
Motors with class 2 efficiency (EFF2) guarantee reduced energy consumptions.

Ease of maintenance
If it is necessary to take the pump apart, it is extremely easy to take out the motor body, without having to disconnect the
pump body from the piping.
FICEM electric pump impellers are equipped with special threaded holes in order to facilitate their removal from the relative shafts.

Anti-corrosion treatment and final painting
All the components which come into contact with fluids in FICEM electric pumps are treated with a special corrosion inhibitor:

• Pickling and alkaline cleaning of the components
• Zinc phosphate primer
• Two coats of epoxy paint (120µ)
• Oven drying at 250 C°

On request, paints suitable for use in the naval and iron and steel sectors can be.
