2 NK Single-Stage Overhung Process Pumps HMS Group, with its proven experience in design and manufacturing of pumps for various industrial applications, using 3D and CFD methods supported by efficient customers feedback, continues to upgrade and retrofit existing products and develop new products lines. Application A new NK series of the centerline-mounted single-stage overhung pumps is designed for operation at refineries, various processes in chemical and petrochemical industry as well as the other industries to handle chemicals products, crude oil, petroleum products, liquefied gases and other similar liquids (by specific gravity, viscosity, corrosion effect on materials, and other factors). NK pumps comply with API 60 (-th ed.) standard, qualified by the modern requirements to efficiency and reliability, and completely respond to currently applied pumps by overall and fitting dimensions. Oil Processing and Petrochemistry In fractionation tower processes: refluxing condensate removal product feeding residues removal In pumping: hot oil overhead products heavy fraction In the following processes: stirring injection circulation heat exchange feeding The NK pumps series are manufactured by the Bobruisk Machine Building Plant (HMS Group division) located in Bobruisk, Belarus. The plant is specializing in the process pumps manufacturing for oil & gas and other industrial applications. Material Options Wet parts materials Suction nozzle arrangement Carbon steel 3% chromium steel Austenitic stainless steel Duplex steel Pumped liquid temperature, С Vertical Horizontal

4 Design Features & Advantages Fig. Fig.. Design of the suction and discharge nozzles corresponds to DIN / ANSI / ISO being rated for 64 bar pressure Heavy duty casing rated for up to 64 bar pressure. 3. The pump rotor can be pulled out without dismantling of the pump casing and pipelines that simplifies the maintenance operations. 4. The hard-alloy wearing rings ensure the pump s performance throughout the whole operational lifetime (Fig. ). 5. The seal chamber meets API 68 and API 60 requirements for application of any compliant mechanical seal. 6. The pumps of various sizes have highly unified main parts that significantly reduces the cost of maintenance. 7. The casing support pads are placed on the pump centreline to avoid misalignment between pump and motor shafts at temperature expansion. 8. A screw-type inducer is installed at the suction side for lowered NPSH (Fig. ). 9. A new energy-efficient flow path provides: High efficiency of the pump with rated and optional rotors; Retention of the rated performance with slightly trimmed impellers; Increased efficiency with deeply trimmed rated and optional impellers; Decreased radial load and shaft runout leading to extended operational lifetime of bearings and mechanical seals

5 NK Single-Stage Overhung Process Pumps Fig. 3 Fig The high-efficient cooling system keeps the pump casing and its bracket at a preset temperature for handling of the hightemperature liquids. The shaft mounted fan is optionally available for better cooling of the bearings houses (Fig. 3).. The rigid shaft with increased diameters provides minimal deflection and runout that extends operational lifetime of bearings and mechanical seal.. The efficient bearings lubrication system ensures their long operational lifetime (Fig. 4). A special mounting of pump to the base plate allows slight displacements of the casing to compensate its temperature expansion. A rigid welded base frame prevents shafts misalignment between pump and motor. Reliable and durable steel membrane coupling reduces vibrations and requires no maintenance. The pump vibration does not exceed limits in accordance with API 60 requirements. The design of the flow path keeps the rotor unloaded from axial forces to extend operational lifetime of the bearings. 0 The design of pump and its base plate provide smooth operation in seismicity areas of up to 9 by МSК-64 scale.
