Selection Chart / Type Key
Curve Specifications: Tolerances according to ISO 9906 Annex A. Curves refer to effective speed of asynchronous motors at 50 Hz. Measurements were carried out with clean water at 20°C with a kinematic viscosity of n = 1 mm²/s (1 cSt). To avoid the risk of overheating, pumps should not be used at a flow rate below 10% of the best efficiency point.
Symbols explanation: Q = volume flow rate, H = total head.

Pump Installation
Important Note: Install a foot valve or check valve in the suction pipe. Support the suction and delivery pipe to prevent damage to the pump casing. [warning-symbol] A diagram illustrates a typical pump installation, showing the pump connected to suction and discharge piping. Key components depicted include a foot valve at the suction inlet, a check valve, a gate valve, pipe supports, and a non-return valve on the discharge line.
