8.7.35 Pilot pump curve data (4.3.18)
Fig. 86 Pilot pump curve data
Description
Pilot ump data is needed for the pilot pump function to work. The
function uses the following data:
3
• Rated flow rate Qnom [m /h]
• Rated head Hnom [m]
• Max. head Hmax [m]
3
• Max. flow rate Qmax [m /h]
• Power, Q0, 100 % speed [kW]
• Power, Q0, 50 % speed [kW]
• Rated power Pnom [kW]
Grundfos can supply hydraulic data for CR, CRI,
CRE and CRIE pumps where GSC files can be
downloaded to CU 354.
All other pump types require manual entering of
hydraulic pump data.
Enter the electrical data, Power, Q0, 100 % speed
and Power, Q0, 50 % speed, manually for all pump
types, including CR, CRI, CRE and CRIE.
For Grundfos E-pumps, enter the data of input power
(P1).
Read the data using the pump performance curves which can be
found in Grundfos Product Center at www.grundfos.com. See the
examples in figs 88 to 91.
If you cannot access Grundfos Product Center, try bringing a
pump into the three duty points:
• Power, Q0, 100 % speed
• Power, Q0, 50 % speed
• Rated power Pnom.
See section 8.7.37 How to read the pump curve data
Product Center.
