Axially Split Casing Multistage Pump

Product Overview

Adopting the newly designed impeller hydraulic model, pump efficiency is 5-10% higher than similar domestic pumps. Wide effective area guarantees the reliable performance and energy-saving feature of the pump to the greatest extent; the impeller is in back-to-back arrangement to balance the axial force, and the remaining axial force is borne by the thrust bearing, and a single impeller is fixed on the shaft to ensure the vibration stability of the rotor components.

The double-suction impeller adopts a special design structure, and the impellers on both sides are evenly staggered to change the frequency of liquid flowing out of the impeller to ensure reliable and stable operation of the pump unit;

The pump body is a horizontal split structure, the suction and the discharge are below the pump shaft line, there is no need to move the pipeline and motor during maintenance, just open the pump cover and lift the rotor to perform maintenance;

The lubrication of the bearing adopts the thin oil lubrication large oil tank design, which can meet the needs of high-speed running. Cooling methods: natural cooling, air cooling, water cooling;

The high-pressure end of the pump is equipped with a pressure relief chamber, which is connected with the suction end through a balance pipe to balance the pressure in the seal chamber of the high-pressure end and reduce the pressure in the mechanical seal chamber;

Application

Oil field and various sewage, sludge, residual oil transportation / crude oil and product oil pipeline transportation.
