Hydrodynamic couplings MG-M-500 are designed for manual and remote speed regulation of boiler feed pumps and other centrifugal pump units to control head and discharge in accordance with system network characteristics.
The hydrodynamic coupling is installed between a motor with a rated speed of 3000 rpm (synchr.) and a pump. Speed regulation is performed via a scoop tube control mechanism.
Centrifugal feed pumps PE 600-300-5 are designed to supply water to stationary steam boilers, with absolute vapor pressure up to 6.2 MPa (63 kgf / cm²). Feed water should have pH 7-9,2, the temperature not more than 438K (165 °C) and should not contain solid particles.
PE pumps are horizontal, centrifugal, multistage, sectional units. Axial forces of the rotors are relieved by a hydraulic thrust bearing. Rotor end seals are mechanical (shaft seals) or gland-type. The rotors are supported by external sleeve bearings with forced or ring lubrication. Torque from the motor to the pump is transmitted via a gear coupling.
Feed pumps PE 600-300-3 are designed to supply feedwater to medium- and high-pressure steam generators with a temperature not exceeding 438K (165°C), pH 7–9.5, solid particle content no more than 5 mg/l, particle size no more than 0.1 mm, as well as other neutral liquids similar to feedwater in viscosity and chemical activity.
