6.1 Pump

Grundfos NKF is a non-self-priming, single-stage, long-coupled
end-suction pump with volute casing. It has an axial suction port
and a radial discharge port with PN 10 or PN 16 flanges

The impeller diameter can be reduced to customise the pump
performance to a certain duty point. This means that the actual
impeller diameter differs from the standard diameter stated in
data booklets, data sheets, etc. The actual impeller diameter is
stated on the pump nameplate.
The pump is equipped with a rubber bellows seal, type BAQE,
with seal faces of metal-impregnated carbon/silicon carbide.
Rubber parts are made of EPDM.
