Pumps lamellar NPL type. Are intended for application in hydraulic actuators of metal-cutting machines and other cars where pressure to 20 MPas (200 kgfs/cm2) is necessary and the stream of working liquid, unregulated in size, with constant pressure is formed.
Pumps have execution on pressure to 6,3 MPas (63 kgfs/cm2), to 16 MPas (160 kgfs/cm2), to 17,5 MPas (175 kgfs/cm2). Pumps are provided for work on pure mineral oils with kinematic viscosity of 25-400 mm of 2/with (cSt). Temperature is from-10 to +60os. Pumps are produced with the right rotation of a shaft (on rotation of an hour hand, to take a detached view the drive). By request of the consumer it is allowed to produce pumps with the left rotation of a shaft. The direction of rotation of a shaft is shown by the arrow placed on the plate. At the order it is necessary to specify a pump standard size, the direction of rotation of a shaft, climatic modification.
Structure of a symbol of the one-line pump:
L NPL 8/16, where 8 — the working volume of cm3;
16 — the nominal pressure of the pump;
l — the direction rotation of a shaft; right without designation.
Till 1995 pumps of the NPL brand had the G12, BG12 brand.
