Specification

Pump housing
The pump housing is designed in such a way that a high
hydraulic efficiency is achieved when the energy
produced by the impeller is converted into pressure.
The pump housing thread enables connection to standard
pipe dimensions.

Pump housing with and without valves
Isolating valve and non-return valve
The COMFORT pump types BX (Europe) and BU (USA)
have a built-in isolating valve and a non-return valve.
The isolating valve ensures that maintenance can be
carried out while the inlet side is isolated.
The non-return valve isolates the outlet side during
maintenance.
Seal ring
The COMFORT pump has just one seal ring between the
spherical motor and the pump housing. The seal ring
material is resistant to hydrolysis and ageing, thus lasting
the entire pump life.

Union nut
The union nut ensures that motor and pump housing are
tightly connected. Thanks to the thread type, the seal ring
is pressed evenly over the entire seal face.
