Horizontal Multi Stage Centrifugal Pumps

KN-C

Product code: KN-C

Application

Red discolored water countermeasure item
Water supply to buildings and factories
Cooling water
Industry
Small regional drinking water
Other general water supply

Feature

Making duplex casing structure and multistage bring quieter operation noise.
Coating nylon on casing, and adopting rust-less material such as Bronze, Resin, Stainless steel, or Rubber for the other parts prevents red discolored water arising form portion contacting liquid.
High head design with multistage structure and smooth water path by nylon coating.
Heater attachable structure for anti-freezing in winter season.
Nylon coated Companion flange is accessory for installation work.
Easy maintenance and inspection without dismantle of piping due to Back-pull-out structure.
