Centrifugal with volute pump NKL

fuelfor hydrocarbonswater

Description
The Type NKL is a PN10 standard pump according to EN 733. Sizes deviating from the characteristic curve are adapted and staged to operators' requirements to achieve the most suitable efficiency. This pump is a single-stage, single-suction volute pump in a light-duty design, with an axial suction nozzle and a centrally located discharge nozzle oriented vertically upwards. Axial thrust is balanced by relief bore(s). The pump shaft is supported by two permanently grease-lubricated deep-groove ball bearings.
