Performance Curves

Selection Example

Design Point Parameters

Suction Capacity: V = 100 m3/h

Suction Capacity: V = 100 m³/h

Suction Pressure: P1 = 40 mbar(a)

Other Parameters Under Standard Operating Conditions (see note)

Select the performance curve closest to Design Point 1.

In this example, the selected curve is 71V.

According to the curve number, identify the corresponding pump model (i.e. ordering code, applicable to standard version only).

For this example, curve 70V corresponds to pump model 2BV-B071.

Note:

The performance curves are based on the following operating conditions: Suction medium: saturated air at 20°C， Service liquid temperature: 15°C，Discharge pressure: 1013 mbar(a)，Performance tolerance: ±10%.

The curves shown on the left side of the chart represent the performance with atmospheric ejector.
