MANUFACTURING
FICEM PI - PID series electric pumps with bare shaft are monobloc pumps with direct coupling to the motor, with offset intake and delivery openings of different diameters, which are not standardised. The electric pumps are equipped with a three-phase asynchronous electric motor (single phase up to 2.2 kW), 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. FICEM electric pumps are available as models with one impeller (PMI series) and with two opposing impellers (PMID series) and the relative PI-PID series bare shaft versions.
The whole range is available with flanged 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.
The electric pumps have a removable motor so it is therefore possible to take out the motor/spindle/impeller for maintenance and/or repair purposes, without having to separate the pump body from the piping.

Carbon/Silicon carbide/EPDM - EPDM/NBR
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.
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.

CONNECTIONS
The whole range of FICEM electric pumps is available with flanged connections and is equipped as standard with sets of nuts and bolts and PN16/40 threaded and/or weld-on counter flanges on request. The rotation of the outlet vent is envisaged.
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:
1. Pickling and alkaline cleaning of the components
2. Zinc phosphate primer
3. Two coats of epoxy paint (120µ)
4. Oven drying at 250 C°
On request, paints suitable for use in the naval and iron and steel sectors can be
