Characteristics
- Cast iron structure (stainless steel on request)
- Class H electric motor from 1.8 kW to 355 kW in efficiency class IE3
- 50 Hz and 60 Hz versions
- Thermal protection devices incorporated in stator
- Long life bearings (100,000 hours)
- AISI 431 drive shaft (AISI 329 on request)
- Leakage detection system in seal chamber (standard) and motor (on request)
- Two silicon carbide mechanical seals with Oil Lifter in large oil chamber
- Discharge from DN50 to DN600
- Large free passage declared for every model
- WET or DRY version available
- Original closed loop cooling system with internal recirculation
- Operating temperature up to 60°C (up to 80° on request)
- Explosion-proof (Designed in accordance with IECEx)
CABLE GLAND
Cable gland system with cable holder. The universal thread ring-nut can be removed to fix a rigid or flexible duct to the cable gland to protect the cable from physical and mechanical stresses. On request a special resin seal is applied to prevent all possibility of water leaking into the motor even if the outer sheath is torn.
ELECTRICAL CONNECTIONS
The terminal board, which simplifies electrical wiring procedures, is in an airtight compartment which can be fitted with a leakage detection sensor.
THERMAL SENSORS
Detects excess heat, therefore, protecting the pump against overheating.
