LAIKO-KWD

KWD is a new generation of non self suction horizontal multi-stage centrifugal pump with a brand new industrial appearance design. The pump adopts axial suction and radial discharge, and the key ﬂow components are made of stainless steel stamping and welding technology. Excellent hydraulic performance and unique structural design, characterized by high eﬃciency, low noise, low vibra-tion, stability and reliability, resistance to mild corrosion, compact structure, beautiful appearance, small size, light weight, and easy maintenance, achieve eﬃcient operation of ﬂuid transportation in various scenarios, and eﬀectively reduce the operating costs of users' pumps.Operating conditions:a liquid that is thin, clean, non corrosive, non ﬂammable, non explosive, easily vaporized, and does not contain solid particles or ﬁbers; When the density of the conveyed medium is greater than that of clean water, a high-power motor is required. Please consult our company for details.Liquid temperature range:
Room temperature type: -20 ℃~+70 ℃
Hot water type: -20 ℃~+105 ℃
Maximum operating pressure: 10 bar
Maximum altitude: 1000m
Maximum ambient temperature:+40 ℃
Medium pH value: 3~9
