NFR

The NFR pumps are intended for operating in communal and industrial sewage cleaners, in agriculture, sugar industry, canneries, metallurgical and paper industry.

Application

The NFR pumps are intended for operating in communal and industrial sewage cleaners, in agriculture, sugar industry, canneries, metallurgical and paper industry. They are intended mainly for transport of fluids polluted with dense filths contains fibrous structures, without contains of air and gases.

Construction

The pumps are horizontal, centrifugal, spiral, single - stage, turn - right, building - block execution. The pumps with their dimensions correspond with DIN 24256. The types are different in hydraulic part, i. e. in impeller type and it’s built into spiral, mechanical part is the same. Construction of NFJ pumps enables the pump disassembly starting from the pump (electric motor) side, without disassembly of suction and discharge pipeline. Hydraulic part consists of multi-bladed peripheral half-opened impeller. Mechanical part creates bearing pedestal. Shaft is located on antifriction bearings, which are lubricated with fat. Seal for packing the hydraulic part is soft cord packing or mechanical seal.
