Agricultural irrigation pumps
Service life increased from three to more than twelve months
When the land is irrigated, ditchwater is regularly sucked up. This water also contains sand particles, which enter the spray system and cause significant wear to the components. To solve the problem, a tungsten carbide spray layer was initially chosen. This produced a service life of around three months.
By using a diffusion technique to increase the surface hardness to as much as 2000 HV, Chromin has greatly increased the pump’s wear resistance. Its service life is now more than one year.
