Bombas de baixa alimentação – Serie ruidosa

GENERAL

The VP series of feed pumps are low-noise, single-stroke vane pumps with constant flow rate.
By using a dampened bell housing (PT) a reduction in noise level is achieved.

 

AREAS OF APPLICATION

  •  filter circuits
  • cooling circuits
  •  lubrication applications
  •  pump transfer units
