Etabloc SYT

Product catalog summary

Overview
This document provides detailed information on thermal oil and hot water pumps, specifically the Etaline SYT, Etanorm SYT, and related models by KSB. These pumps are designed for reliability, robustness, energy efficiency, and ease of service, suitable for heat transfer systems and hot water circulation.

1. Maximum Operating Reliability

Features a highly effective venting contour, VenJet, for optimal venting.
Optional single mechanical seal with leakage monitoring for reliable seal condition control.
Confined gaskets and a design variant with a double mechanical seal in tandem arrangement.
Anti-seize carbon plain bearing lubricated by the fluid handled.
Shaft seal rings protect the deep groove ball bearing from heat transfer fluid ingress.
Impeller secured by Nord-Lock washers for enhanced reliability.

2. Robust Design

Sturdy discharge cover for high stiffness.
Optimized heat barrier with minimal wear.
SiC/SiC bearing design for high resistance.
Reinforced C4-type deep-groove ball bearing with special grease for long service life.

3. High Energy Efficiency

Optimized hydraulic system for high efficiency.
Impeller trimmed to match specified duty points.
Suitable for variable-speed operation with IE3 and KSB SuPremE® IE5 motors as standard.
