Pumps for 50 32 125 technical specifications. Overall and mounting dimensions of the flange
Cantilever pumps K50-32-125 are a type of centrifugal pump with a one-way liquid supply to the impeller located at the end of the shaft remote from the drive. The units are equipped with an electric motor, usually installed on a single platform or connected by a flange. Cantilever pumps K50-32-125 are used for pumping water, chemically active liquids, liquids containing impurities and solids.
Console pumps K and console-monoblock pumps KM (electric pumping units based on them) are not intended for use in explosive and fire hazardous areas.
Cantilever pumps K - centrifugal, horizontal, cantilever pumps with housing support. The K50-32-125 pump is designed for pumping fresh water, liquids similar to water in density, viscosity and chemical activity. K50-32-125 are widely used in water supply, heat supply and heating systems, as well as for maintaining pressure in the heating or water supply system in multi-storey buildings.

Installation of console pumps K50-32-125
It is recommended to install the K50-32-125 pump on a level and high-quality concrete base, which can ensure reliable fastening of the purchased pump. The foundation must absorb various vibrations, shocks and linear deformations. The mass of the foundation should be one and a half times the mass of concrete. And its width and length should be one meter greater around the perimeter of the supporting frame. The pump is installed in the center of the concrete base and secured. When installing pipes, it is necessary to ensure that no mechanical forces are transferred to the pump housing. To achieve excellent performance of the K50-32-125 cantilever pump, you need to minimize vibration and noise.
Cantilever pumps K50-32-125 belong to the group of centrifugal horizontal single-stage pumping units supported on the pump housing and mounted on a single supporting frame or plate. The driving working movement from the electric motor to the pump is carried out through an elastic coupling. Cantilever pumps are widely used at pumping stations of urban, industrial and rural water supply as mechanisms for drainage, irrigation and irrigation of land, for pumping clean water (drinking and technical) with temperatures up to 140°C and non-explosive liquids similar to water in density and viscosity (up to 36 cSt) and chemical activity (pH from 6 to 9). The limit of solid inclusions is 0.2 mm, the concentration is no more than 0.1% of the total volume of the pumped liquid. The liquid should not contain fibrous materials, ash, slag, sand and other impurities. Used in pumps K50-32-125 electric motors - voltage 380 V, current frequency 50 Hz, type of current - alternating.

Description
K50-32-125 is a horizontal cantilever pump for water with temperatures up to 85°C (or up to 105°C with a mechanical seal on special order), or for liquids with similar chemical properties and density, i.e. the maximum amount of solid inclusions should be 0.2 mm, and the concentration should be 0.1%.
One of the most popular water pumps, it is widely used in industrial sectors, urban and agricultural sectors, in water supply and for irrigation of land.
Centrifugal cantilever pumps K50-32-125 are equipped with a shaft seal, but if the pump marking ends with the designation -5, then the pump has a mechanical shaft seal.
The pump type K50-32-125 is equipped with a three-phase asynchronous electric motor 1.5/3000 (kW/rpm), mounted on a common frame and connected through an elastic coupling.
An impeller is mounted inside the pump on a steel shaft. When turning the pump impeller, the pump parameters change downward, and the power requirement for the electric motor, accordingly, also decreases. The pressure side pipe is directed upwards vertically, the inlet pipe is directed horizontally.
When water is supplied, the pump drive, spinning the impeller, creates centrifugal force and water under pressure is discharged through the pressure pipe.
