Product Description
The lightweight horizontal multistage centrifugal pumps CHL, CHLK and CHLF are equipped with a maintenance-free mechanical seal. The pump flow parts are made of stainless steel (304 or 316), and various materials of carbide seals guarantee the absence of leaks when pumping various media; low noise level: the pump operates smoothly on two low-noise bearings and, with the exception of the weak sound of the engine, is almost silent; Low failure rate: the simple and rational design significantly increases the mean time between failures of the entire unit. They have such characteristics as low noise level, resistance to mild corrosion, attractive appearance, small size and weight, and long service life.
The unit has a horizontal multi-stage impeller design. The wheels and guide vanes are made of stamped and welded stainless steel, have a closed wheel design and one-way suction. Working media include clean water, mildly corrosive liquids, medium temperature for the standard version from -15°C to +70°C, for the hot version - up to +110°C.
