SAM21_P578 Centrifugal Pumps

Product catalog summary

Introduction
This document presents the specifications and applications of compact, high-performance centrifugal pumps designed primarily for whirlpool bathtubs but applicable in various sectors such as domestic, industrial, and zootechnics. These pumps are noted for their silent operation and are constructed from high-quality materials resistant to corrosion and oxidation, ensuring long-term efficiency.

Specifications
The pumps are designed to prevent the engine from contacting water, ensuring total isolation. They are self-priming and operate continuously (S1 duty) with a 2-pole motor. The insulation class is F, and they feature an automatic reset thermal protector. The pumps are available with Sensorless Brushless DC motors without control electronics and have protection ratings of IP55 (AC) and IP54 (DC). They operate within a tolerance of +/- 10%, with a maximum liquid temperature of +60°C and an ambient temperature limit of +40°C.

Standards and Compliance
The pumps are manufactured in accordance with several standards, including EN 60335-2-60, EN 60335-1, EN 50366, EN 55014-1, EN 55014-2, EN 61000-3-2, EN 61000-3-3, EN 60034-1, EN 60034-30, and EN 60335-2-41. They comply with EMC (2004/108/EC), LVD (2006/95/EC), and EMF standards (EN 60335-1/EN 50336).

Optional Features
On request, the pumps can be provided with special voltages, a 60Hz version, dual-frequency, cRUus certified motors for selected voltages, and three-phase motors.

Materials and Construction
The pump casing is made of PPO RYTON, the impeller of PVC, and the mechanical seal includes alumina and graphite components. The SAM21-2 model has an absorbed power of 0.18 kW, while the SAM21-3 and SAM21 DC-24V models have 0.20 kW.

Performance Data
The document includes performance curves for different models, showing the relationship between flow rate (Q) and head (H) at various speeds (2900 rpm to 3400 rpm). The hydraulic characteristics are specified for water at 20°C at nominal pump speed, with tolerances according to ISO 9906-2012.
