Centrifugal Process Pump R / RN / RNS Series

Foot mounting, single volute casing with end suction and top discharge nozzles. Shaft supported by oil lubricated ball bearings. Lubrication assured by a constant level oiler. The impeller is hydraulically and dynamically balance and designed to achieve high efficiency and low N.P.S.H. values. The shaft is always provided with its protective sleeve; in case of packed gland the deep stuffing box allows the fitting of a lantern ring between the packing rings for flushing purpose.

Particularly suited to pump clear or slightly cloudy liquids in any industrial field: chemical pharmaceutical industries, steelworks, refineries, paper mills, textile industry, shipyards, mining, food processing industry, bakeries, confectionery industry, sugar plants, beverage industry, oil mills, dairies, etc.

TECHNICAL INFORMATION
For the applications where the value of N.P.S.H. available on the plant is very low, the pumps can be
equipped with an inducer in order to reduce the required N.P.S.H.

ACCESSORIES
The pump line R is of the back-pull-out type, therefore, where the pumping group is equipped with a spacer type coupling,
the complete rotor can be removed from pump casing without disturbing piping and driver.
Hence the group does not need to be realigned making much more easier overhauling operations.
The pump can also be fitted, according to the liquid being pumped, with single or double, balanced or unbalanced mechanical seals.

PERFORMANCES
Capacity up to 1500 m3/hHead up to 130 m liquid column
Speed from 720 to 3500 R.P.M.
The pumps can operate under positive suction head or under suction lift after they have been primed.
