Standardised Pumps / Close-coupled Pumps Overview
The document provides comprehensive details on the Etachrom L series pumps, which are standardized and close-coupled, adhering to EN 733 standards. These pumps are versatile, used in various applications such as cleaning, water treatment, and industrial processes.

Main Applications and Fluids Handled
The Etachrom L pumps are suitable for systems like fire-fighting, irrigation, and air-conditioning. They handle a range of fluids including service water, drinking water, and high-temperature hot water.

Operating Data
The pumps operate at 50 Hz and 60 Hz, with a flow rate up to 260 m³/h and a head up to 105 m. They can manage fluid temperatures from -30°C to +110°C and an operating pressure up to 12 bar.

Design Details
Featuring an annular casing with a back pull-out design, these pumps are horizontally installed and single-stage. They include a KSB surface-cooled IEC three-phase motor and a single mechanical seal.

Product Benefits
The pumps offer maintenance-free operation, easy dismantling, high efficiency, corrosion resistance, and a long service life.

Certifications and Tests
Certified for ISO 9001 quality management and French drinking water approval, the pumps undergo materials inspection, final inspection, and hydraulic tests. Warranties are provided as per sales terms.

Specifications and Performance Data
The document lists various models categorized by rotational speeds (1450 rpm, 1750 rpm, 2900 rpm, 3500 rpm) with specific dimensions and performance metrics. Performance data includes flow rate and head, crucial for selecting the appropriate model.

Dimensions and Weights
Detailed dimensions for each model are provided, essential for installation and integration into systems.

Key Models and Standards Compliance
Key models like 50-25-125 and 100-80-250 are highlighted, designed to meet different industrial needs. All pumps comply with EN 733 standards, ensuring reliability and compatibility.

Technical Specifications and Guidelines
The document includes information on pump components, interchangeability, flange dimensions, spare parts, and designation keys. It outlines sizes and weights of components and provides flange dimensions according to EN 1092-1 standards.

Interchangeability and Spare Parts
A table shows the interchangeability of Etachrom L and B components. Spare parts recommendations for two years of operation are provided, listing quantities for various components.

Designation Key
A detailed key helps decode pump type, size, material, design, and other features, aiding in identifying specific configurations.

Contact Information
The document concludes with contact details for KSB Aktiengesellschaft, including address, phone number, and website.
