6” Pumps 6TN series
Manufactured completely in Bizzi & Tedeschi factory located in Campegine-Italy, thanks to the use of fine quality materials and construction which takes care of details, this product meets low cost and long life requirements. The duration especially represents an element which is much greater than similar products of competitor brands.
The 6TN series pump is of centrifugal multistage type with radial and semi-axial flow, equipped with coupling flange in accordance with Nema Standards, suitable to pump water from very deep wells.
The external jacket is 2 mm thick stainless steel to guarantee sturdiness and solidity.
The coupling, shaft and suction filter are in stainless steel.
Impellers, disks and diffusers are made in Lexan, originally by Sabic (ex General Electric), which are among the best wear-resistant thermoplastic materials present on the market.
The disks and diffusers are equipped with stainless steel wear rings in the areas in contact with the impellers to provide smooth rotation and long life.
Stainless steel shaft sleeves plated in thick chromium which rotate inside rubber abrasion-proof bearing bushes to grant high wear-resistance.
Valve body and suction casing in cast iron with nickel-plated treatment.
Antifriction ring to protect pump from potential counterthrust.
