11.6 Blanking flange
A blanking flange is used to blank off the opening when one of the
pump heads of a twin-head pump is removed for service to
enable uninterrupted operation of the other pump. See fig. 63.

11.7 Insulating kits for air-conditioning and cooling
systems
You can fit single-head pumps for air-conditioning and cooling
systems with insulating shells. A kit consists of two shells made
of polyurethane and a self-adhesive seal to ensure tight
assembly.
The dimensions of the insulating shells for pumps in
air-conditioning and cooling systems differ from those of the
insulating shells for pumps in heating systems.
Insulating shells for single-head pumps for heating systems are
supplied with the pump.
12. Technical data
Supply voltage
1 x 230 V ± 10 %, 50/60 Hz, PE.
Motor protection
The pump requires no external motor protection.
Enclosure class
IPX4D (EN 60529).
Insulation class
F.
Relative air humidity
Maximum 95 %.
Ambient temperature
0 to +40 °C.
During transport: -40 to +70 °C.
Temperature class
TF110 (EN 60335-2-51).
Liquid temperature
Continuously: -10 to +110 °C.
Stainless-steel pumps in domestic hot-water systems:
In domestic hot-water systems, we recommend that you keep the
liquid temperature below 65 °C to eliminate the risk of lime
precipitation.
System pressure
The maximum permissible system pressure is stated on the pump
nameplate:
PN 6: 6 bar / 0.6 MPa
PN 10: 10 bar / 1.0 MPa
PN 16: 16 bar / 1.6 MPa.
Test pressure
The pumps can withstand test pressures as indicated in EN
60335-2-51. See below.
• PN 6: 7.2 bar
• PN 10: 12 bar
• PN 6/10: 12 bar
• PN 16: 19.2 bar.
During normal operation, do not use the pump at higher
pressures than those stated on the nameplate.
The pressure test has been made with water containing
anticorrosive additives at a temperature of 20 °C.
