Thermoplastic Centrifugal Pump Type NM
The document outlines a horizontal, single-stage, non-self-priming chemical pump adhering to DIN 24256, EN 22858, and ISO 2858 standards. It features a single flow spiral casing with a modular design, available in sizes from NM 32–125 to NM 150–400. Key components include an axial suction socket, radial pressure socket, closed radial impeller, and axial thrust compensation via relief bores. The pump is powered by a three-phase motor up to 150 kW and includes a bend-resistant stainless steel shaft with optional oil lubrication.
The pump supports flow rates up to 450 m³/h at 1450 rpm and 200 m³/h at 2900 rpm, with a head up to 60 m and 100 m respectively. Material limits are specified for PE-HD, PP, and PVDF, with maximum operating temperatures of 60°C, 80°C, and 110°C. The pressure socket nominal width ranges from DN 32 to DN 150, and explosion protection is available upon request.
This pump is ideal for chemical plants, water treatment, and process engineering, capable of transporting neutral or aggressive fluids, provided the components in contact with the medium are resistant at the operating temperature.
Constructed from thermoplastic materials, the pump ensures high operational reliability and resistance to corrosion and wear. It features a modular design for easy maintenance and part replacement. The impeller is mounted independently of the rotational direction, and the shaft is protected by a sleeve made of carbon or thermoplastic materials.
Available options include an ASV pump monitor, self-priming container, steel base plate, housing drainage, and a smooth starting unit.
The document provides detailed dimensions for various pump sizes, baseplate sizes, and coupling allocations, including specifications for mounting height, motor dimensions, and baseplate execution according to DIN 24259.
The sectional drawing and component part register list key components such as the spiral casing, suction connection, housing flanges, pressure connection, casing cover, support foot, shaft, impeller, radial ball bearings, and bearing carrier.
