Centrifugal horizontal pumps of double-sided entry type "D" and units based on them, driven by an electric motor, are designed for pumping and lifting water and other liquids, water-like properties for viscosity and chemical activity, with temperatures up to + 85 ° C, with a content of solid inclusions , Not exceeding 0.05% by weight and a maximum size of up to 0.2 mm. They are used for urban, industrial and agricultural water supply, in farming and horticulture, in construction and municipal services, in the mining and metallurgical industries, as well as for drainage and irrigation.
Pumps type D - have a two-sided semi-helical fluid supply to the impeller and a spiral tap. The pump housing has a connector in the horizontal plane. The location of the suction and discharge nozzle in the lower part of the pump housing allows repairs without disconnecting the pipes and dismantling the engine. The motor drives the pump rotor through an elastic sleeve-finger coupling. The bearings of the rotor are radial or radial-thrust bearings with grease. Shaft seal - gland type. The impeller is a vestibular inlet, which ensures the equilibrium of the axial forces. Materials of the main parts of the pumps are gray cast iron, carbon steel.
