Product Overview
Facility utility room circulation lines and heat transfer loops use the Grundfos NB 100-315/295 end-suction pump. Fitted with a 18.5 kW motor, system piping interfaces through an axial DN 125 suction port and a radial DN 100 discharge flange.
Liquid circulation performance achieves approx. 3539 L/Min maximum delivery with a developed head of approx. 30.5 m. Housing construction features cataphoretically coated EN-GJL-250 cast iron, accommodating a stainless steel impeller and a BQQE mechanical seal. Net weight measures 268 kg.
Plant power feed of 415 V three-phase operates the unit, drawing 34.9 Amps rated current for 18.5 kW. Fluid temperature capabilities range from -25°C to 120°C under working pressure limits up to 16 bar. Flange interfaces are dimensioned at DN 125 inlet and DN 100 outlet.
Motor frame structure conforms to IP55 sealing requirements alongside Class F insulation. External motor overload protection must be provided by the installer. The back-pull-out construction allows extraction of the motor and rotating components without disturbing suction or discharge pipe connections.
Features
- Replaceable wear rings protect casing hydraulics and retain designed pumping clearances.
- Solid stub shaft and ball bearing arrangement counteracts operating mechanical stresses.
- Standardized PN16 dimensions per EN1092-2 align with facility pipe headers.
- IEC standardized electric drive rated for continuous S1 operation in ambients up to 40°C.
- Back-pull-out arrangement allows fast access to motor and impeller without disturbing pipework.
- Precision balancing of rotating parts delivers quiet, low-vibration fluid transfer.
- Heavy-section cast iron volute with integral mounting pads provides solid base support.
