Fi-Fi System Pumps

Description :
•    These are horizontal type, single stage, single entry, horizontal volute type pumps with a horizontal suction port on the axis and the discharge port on the top, and enclosed impeller.
•    Since the volute is symmetrical it can be assembled to be used in either direction. Thanks to this feature, it can also be used with motors which rotate counterclockwise.
•    UNM pump impellers are dynamically balanced to the base. The axial thrust is compensated by rear back wear rings and balance holes.
•    The pumps are equipped with a rigid shaft that can operate under different loads.
•    The sliding bearing within the suction body is lubricated with water.
•    The construction is compact thanks to the short distance between the bend-resistant shaft and bearing and the volute. This feature allows it to be used in space-restricted (eg.Marine Fire Brigade)
•    In standart configurations, two roller bearings are used. A console bearing is optional.
