NR-152

Product catalog summary

Applications
The document outlines the use of 6” submersible electric pumps designed for water lifting, pressurizing, and distribution in both civil and industrial settings. These pumps are applicable for autoclave and cistern inlets, washing plants, and irrigation systems, and can draw water from wells with a minimum diameter of 156 mm, tanks, or natural basins.

Construction Features
The NR152 model includes a complete pump unit with a 4” oil-filled electric motor (CL95 series) up to 4 kW or a 6” water-filled electric motor (MS152 series) from 5.5 kW. The NP152 model is a hydraulic component compatible with 4” or 6” submersible motors with NEMA standard couplings. The pumps are equipped with radial or semi-axial impellers, a non-return valve, and components made from materials that ensure high wear resistance.

Materials - Standard Version
Impellers and diffusers are constructed from polycarbonate reinforced with fiberglass. The shaft is made of AISI431 stainless steel, while the outlet and suction support are made from FeG450 steel or cast iron EN-GJL-250. The external shell is composed of AISI304 stainless steel.

Operation Data
The pumps are suitable for handling fluids that are chemically and mechanically non-aggressive, without solid substances or abrasive parts. They can pass solids up to 4 mm in size and operate with liquid temperatures ranging from 0°C to 35°C (CL95) or up to 30°C (MS152). The maximum working pressure is 54 bar, and the maximum immersion depth is 300 meters. The direction of rotation is counterclockwise when viewed from the outlet.

Performance
At 2900 rpm, the NR152 models have varying maximum flow rates (Qmax) and head (Hmax) capabilities: NR152 A (18 m3/h, 480 m), NR152 B (26 m3/h, 540 m), NR152 C (45 m3/h, 410 m), NR152 D (56 m3/h, 363 m), and NR152 E (64 m3/h, 366 m).

Installation
The pumps can be installed vertically or horizontally, depending on the power requirements.

Special Versions
Special versions include stainless steel AISI304 precision casting for the inlet and outlet, brass impellers, and different voltage options.

Accessories on Request
Available accessories include a control panel and cable joint.
