SQ 2 - curve and technical data

Sep 26, 2026

Performance curves and technical data for pump series SQ 2, SQ 2-N, SQE 2, and SQE 2-N, including efficiency versus flow-rate charts (Q) and power/efficiency (P2, eta) plots. The document provides dimensions, weights, and stage counts for multiple pump types (e.g., SQ 2-35 to SQ 2-115). It also lists electrical data such as input/output power (P1/P2), required pump power, rated current at 200 V and 230 V, and rated motor efficiency.

FAQs

Which pump models are covered in the document?

The document covers SQ 2, SQ 2-N, SQE 2, and SQE 2-N pump series.

What technical parameters are included besides performance curves?

It includes dimensions and weights (net weight and shipping volume) as well as electrical data such as input power, output power, required input power for the pump, rated current, and motor efficiency.

How are efficiency and power related to flow rate in the performance section?

The performance curves present efficiency (eta) and power (P2) plotted against flow rate Q, showing how pump efficiency changes across different flow values.
