Etaline Z
Etaline Z
The document is a technical guide for the Etaline Z in-line twin pump, designed for heating, air-conditioning, and ventilation systems. It covers both fixed and variable speed versions operating at 50 Hz.
The Etaline Z is suitable for service water supply systems, heating systems, industrial recirculation systems, air-conditioning systems, cooling circuits, and water supply systems, excluding drinking water as per German regulations.
The pump is designed to handle fluids that are not chemically or mechanically aggressive to the materials used in the pump.
The Etaline Z features a closed-coupled design with a single-stage, horizontal or vertical installation. It includes a rigid connection between the pump and motor, and a back pull-out design. The pump casing is radially split with an in-line design.
For fixed speed versions, the pump uses a KSB/Siemens surface-cooled IEC frame three-phase squirrel-cage motor. Variable speed versions utilize the KSB SuPremE motor, a magnetless synchronous reluctance motor, requiring PumpDrive 2, PumpDrive 2 Eco, or PumpDrive R.
The pump components are made from materials such as grey cast iron, stainless steel, and bronze, depending on the part and application.
The Etaline Z offers maximum energy efficiency through demand-driven operation, especially when combined with the KSB SuPremE IE4/IE5 motor. The PumpDrive systems are factory-set for optimal performance, and the PumpMeter provides transparency in pump operation.
The pump operates with a flow rate up to 1095 m3/h and a head up to 38.5 m. It supports fluid temperatures from -30°C to +140°C and an operating pressure up to 16 bar.
The document includes detailed information on dimensions, connections, flange design, installation types, and available accessories.
The product complies with various regulations, including REACH and the Ecodesign Directive, with specific efficiency indices and construction details provided in the data sheet.
The document lists multiple pump models with their respective motor efficiency classes (IE4, IE5), power ratings (kW), current (A), and motor weights (kg). The pumps operate at a speed of 1500 rpm and are designed for use with a 3-phase 400 V power supply.
The document includes selection charts for fixed speed versions of the pumps operating at 1450 rpm. It provides characteristic curves for different models, indicating flow rates (Q) in cubic meters per hour (m³/h), head (H) in meters, and power (P) in kilowatts (kW).
Efficiency classes are specified, and correction factors are provided for pumps with steel impellers. The document notes that performance data must be adjusted based on fluid density and viscosity.
The document outlines the NPSH (Net Positive Suction Head) values, emphasizing that these values are critical for preventing cavitation. It also mentions that NPSH values for part-load conditions require significant technical effort to measure.
The document contains graphical representations of performance curves for various pump models, illustrating the relationship between flow rate, head, and power consumption.
The document provides detailed specifications and installation guidelines for Etaline Z in-line twin pumps with PumpDrive 2, focusing on dimensions, connections, flange design, and installation types.
The document outlines the connection types for pressure gauges, vent connections, and fluid drain/priming. It specifies the connection sizes for different pump models, ensuring compatibility with Rc and G standards.
Flange dimensions are provided according to EN 1092-2 and ASME B 16.1 standards, detailing the number of holes and diameter for each nominal pipe size (NPS).
Instructions for both horizontal and vertical installations are included. Horizontal installations require adequate support for motors of size 180 and above, while vertical installations use specific venting connections to prevent dry running.
The document briefly mentions the availability of pump accessories, although specific details are not provided in the excerpt.
The document lists various accessories for Etaline Z pumps, including pump feet and blind flanges with specific material numbers and weights. It specifies the pump sizes these accessories are compatible with, such as Etaline Z 032-032-160 to 080-080-250 and others.
General assembly drawings are provided for different pump sizes with bolted and clamped casing covers. These drawings include side views and details on fastening elements for impellers and casing covers.
The document includes a detailed list of components with part numbers and descriptions, such as volute casing, impeller, mechanical seal, and various bolts and nuts.
The glossary explains terms like ACS (French drinking water regulations), back pull-out design, close-coupled design, and various efficiency classes (IE1 to IE5). It also defines terms like in-line design, mechanical seal, and regulatory approvals like WRAS and UBA.
The document provides contact details for KSB SE & Co. KGaA, including their address in Germany and a website link.
